Title: Tights-type leg support garment

Description:
TECHNICAL FIELD  
      The present invention relates to a tights-type leg support garment, and particularly relates to a stretchable leg support garment in which stretchable portions having relatively great straining forces are provided at specific positions.  
     BACKGROUND ART  
      Among parts of the human body, the knees tend to have orthopedic troubles most often, due to declines with age of muscles and ligaments that support the knees, injuries to the knees in sports, etc.  
      Recently, care of injuries to the knees and protection of the knees have been carried out by applying a taping treatment or a corset to a part of the human body that requires the same, occasionally.  
      However, the taping treatment is difficult to carry out for oneself, and it is necessary to ask the others, specifically the specialists, to conduct the same since the taping treatment requires skills that are not available from inexperienced persons. Therefore, it involves inconvenience in application and removal. Besides, long period application of the same should be avoided, since it could cause skin disorders. Furthermore, the taping treatment fixes the knee joint, thereby decreasing the degree of freedom of the movement of the knee joint. On the other hand, in the case where a corset is employed, the degree of freedom of the movement of the knee joint likewise decreases significantly, since a corset does not provide sufficient freedom to the patella.  
      Recently, various garments that support specific muscles have been proposed (JP 4(1922)-343868 A, JP 4(1992)-57902 A, JP 4(1992)-50302 A, JP 8(1996)-81807 A, JP 9(1997)-241906 A, JP 10(1998)-280209 A, etc.).  
      Such garments having muscle-supporting functions are generally provided with stretchable portions having relatively great straining forces at positions over or beside muscles to be supported.  
      However, these garments having muscle-supporting functions are designed not particularly from the viewpoint of the protection of the knees.  
      As to the human body, even taking a standing position causes the knees to warp. More specifically, a force causing the legs to bend convexly with the medial side of each knee joint being a vertex is applied to the legs, thereby applying more tension to the ligamentum collateralle of each knee joint on the medial side thereof (the ligamentum collateralle on the medial side is hereinafter referred to as ligamentum collateralle medialis). The ligamentum collateralle medialis is covered with tendons on inferior sides of the musculus sartorius, the musculus semitendinosus, the musculus semimembraneous, and the musculus gracilis, thereby being protected. However, if these muscles fatigue or become weaken with age, it is impossible to resist against the foregoing force with only the ligaments, and hence, the knees are made unstable.  
      Meanwhile, few studies have been made on garments for supporting the ligamentum collateralle medialis of the knee joint of the human body. Statistics, however, show that there are considerably many cases of disorders to the ligamentum collateralle medialis of the knee joint, among the disorders of the knee joint. Therefore, it has been found that, with a view to providing sufficient support to the knees while securing the freedom of the movement of the knees, studies should be focused on the ligamentum collateralle medialis.  
      The ligamentum collateralle medialis is located at a position slightly posterior to the medial side of each knee joint, extending between the vicinity of an inferior end of the os femoris and the vicinity of a superior end of the tibia. On the lateral side of the knee joint, opposite to the ligamentum collateralle medialis, the ligamentum collateralle lateralis is located, extending between the vicinity of the inferior end of the os femoris and the vicinity of a superior end of the fibra. It should be noted, however, that cases of disorders of the ligamentum collateralle lateralis are significantly less than cases of disorders of the ligamentum collateralle medialis; namely, cases of disorder of the ligamentum collateralle medialis are many. This is because that the ligamentum collateralle medialis has a small tensile strength as compared with that of the ligamentum collateralle lateralis, and hence, exhibits a small degree of extension before fracture. In other words, the ligamentum collateralle medialis is inferior to the ligamentum collateralle lateralis in strength and elasticity.  
      As described above, the ligamentum collateralle medialis is covered with tendons on inferior sides of the musculus sartorius, the musculus semitendinosus, the musculus semimembraneous, and the musculus gracilis, and is located at a position slightly posterior to the medial side of the knee joint. Therefore, there has been no muscle support garment that is focused on and actually intended to provide the support of the ligamentum collateralle medialis.  
      The inventors of the present invention made studies centering on the support of the ligamentum collateralle medialis and aimed to providing a leg support garment that is capable of effectively protecting the knees and stably maintaining the knee joints without decreasing the degree of freedom of the movement of the knee joints, that provides a good feeling when worn, and that is useful for preventing and reducing gonalgia caused by the instability of the knees, and further, for preventing injuries to the ligamentum collateralle medialis caused by sports or the like.  
     SUMMARY OF THE INVENTION  
      With the foregoing in mind, the present invention is to provide a leg support garment as described below. It should be noted that the following description includes auxiliary headings in brackets &lt; &gt; at the top of respective sections of descriptions corresponding to claims, but these are provided merely for conveniences in referring to the contents of the present invention, and do not limit the present invention at all.

      wherein the stretchable part having a relatively great straining force includes a stretchable portion (A) having a relatively great straining force that: 
          substantially covers the ligamentum collateralle on a medial side of the knee joint of the human body; and     on a superior side of the knee joint, extends through a length of not less than ¼ of that of the thigh, along at least one selected from the musculus group consisting of the musculus sartorius, the musculus semitendinosus, the musculus semimembranosus, and the musculus gracilis.        

      In the leg support garment of a tights type of the present invention, the stretchable portion (A) having a relatively great straining force supports the ligamentum collateralle medialis, and further, on the superior side of the knee joint, supports at least one selected from the musculus group consisting of the musculus sartorius, the musculus semitendinosus, the musculus semimembranosus, and the musculus gracilis that are located over the ligamentum collateralle medialis and extend upward. Therefore, a power of pulling up the stretchable portion having a relatively great straining force that supports the ligamentum collateralle medialis is produced by the portion extending upward in the stretchable portion (A) having a relatively great straining force, thereby increasing the power of supporting the ligamentum collateralle medialis. Further, at least one of the musculus sartorius, the musculus semitendinosus, the musculus semimembranosus, and the musculus gracilis that support the knee joint in cooperation with the ligamentum collateralle medialis is also supported by the stretchable portion having a relatively great straining force.

Though not shown, the musculus rectus abdominis is located at the center of the abdomen region, vertically from a superior part of the abdomen region on the inferior side of the thorax to the hypogastric region. Though not shown, the musculus obliquus externus abdominis is located at each of the right and left sides of the musculus rectus abdominis, and its muscular fibers are directed in an obliquely upward direction toward each side. Further, though not shown, the musculus obliquus internus abdominis is located substantially on the dorsal side of the musculus rectus abdominis and each musculus obliquus externus abdominis, and its muscular fibers are directed approximately in an obliquely downward direction toward each of the right and left sides from the center front line.  
      For descriptions of the ligamentum collateralle medialis and the like, a part of the skeleton and the ligaments in the vicinity of the knee joint is shown in  FIGS. 127 and 128 .  
       FIG. 127  is a rear view of the knee joint viewed from the dorsal side, and an arrow A indicates the medial side of the body while an arrow B indicates the lateral side of the body.  FIG. 128  is a side view of the knee joint viewed from the medial side (the arrow A side), and an arrow D indicates the anterior side of the body while an arrow E indicates the posterior side of the body.  FIG. 128  illustrates a state in which the knee is bent.  800  denotes the ligamentum collateralle medialis.  801  denotes the ligamentum collateralle lateralis.  803  denotes the condylus medialis of the tibia.  804  denotes the condylus lateralis of the fibula.  805  denotes the meniscus medialis.  806  denotes the meniscus lateralis.  807  denotes the ligamentum cruciatus posterior.  709 ′ denotes a part of the tendon of the musculus biceps femoris, and the muscle on the superior side of the same is not shown.  
      As explicit from these drawings, the ligamentum collateralle medialis is located at a position slightly posterior to the medial side of the knee joint, extending between the vicinity of the inferior end of the os femoris and the vicinity of the superior end of the tibia.  
      It should be noted that the positions, shapes, and sizes of the bones and muscles vary slightly with the individual body, and the foregoing muscle and skeleton charts illustrate a mere typical example.  
      The directions of the muscular fibers are lengthwise directions of thin lines drawn in the muscles shown in the drawings, and these directions of the muscular fibers are directions in which the muscles contract. It should be noted that that the positions, shapes, and sizes of the bones and muscles vary slightly with the individual body, and the foregoing muscle and skeleton charts illustrate a mere typical example.  
      Since, as described above, the positions, shapes, and sizes of the bones and muscles vary slightly with the individual body and the body itself varies in size, there is no harm even if the positions on a garment of stretchable portions having relatively great straining forces and those having relatively small straining forces are shifted slightly from the predetermined specified positions, respectively, as long as they are in ranges such that the objects of the present invention can be achieved.  
      The following description will explain specific embodiments of a leg support garment of the present invention while referring to drawings, to make the present invention easily understood. However, the leg support garment of the present invention is not limited to those shown in the drawings.  
      Furthermore, in the following description, the positions of stretchable portions having relatively great straining forces and the like in the leg support garment of the present invention are described using names of muscles, ligaments, tendons, and bones. This intends to describe a position of a stretchable portion having a relatively great straining force or the like in a simpler manner, using names of muscles, ligaments, tendons, bones, etc. of the body, so as to indicate that the portion is to pass over, or in the vicinity of, a portion where the muscles, bones, and the like are located. In the garment other than the stretchable portions having relatively great straining forces, only specific small portions such as seam lines and others are made of portions having particularly small stretchability or no stretchability, and most portions of the garment are made of fabrics having stretchability and straining forces relatively smaller than those of the stretchable portions having relatively great straining forces. The matters described above apply to the other embodiments described below.  
      In the present invention, “the stretchable portion having a relatively great straining force substantially covers the ligamentum collateralle on the medial side of the knee joint” means that the portion may not necessarily cover the entirety of the ligamentum collateralle medialis, but may cover a majority of the same. More specifically, it means that, on the superior side of the knee joint, substantially the entirety of the ligamentum collateralle medialis is covered with the stretchable portion having a relatively great straining force, while on the inferior side of the knee joint, only a part of the ligamentum collateralle medialis to a position corresponding to an inferior end of the patella is covered with the stretchable portion having a relatively great straining force.  
      Furthermore, in the drawings illustrating the embodiments of the garment of the present invention, if FIGS.  1  to  4  are taken as an example,  1  schematically denotes a position where the patella is located; it does not indicate a size of the patella. It also is used to indicate a central position of the knee joint. It should be noted that in a rear view of the garment according to the embodiment of the present invention also, the marking of the position of the patella facilitates the understanding of the garment of the present invention in the descriptions with reference to the drawings. Therefore, the position of the patella is indicated with a circle of a broken line. In a cross-sectional view taken on an A-A′ line and a side view also, the position of the patella is indicated with a half-circle.  
       FIG. 1  is a rear view of an embodiment of a tights-type leg support garment having a length capable of covering a range from a waistline to the superior side of the ankle according to the present invention (a long-type garment of this kind is hereinafter referred to as “long-tights-type garment” also).  FIG. 2  is a front view of the same.  FIG. 3  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 2 .  FIG. 4  is a side view of the garment obtained when seen from the right side viewed in the front view (in this case,  FIG. 2 ). Such a side view obtained when seen from the right side viewed in the front view is hereinafter referred to as the right-side view simply.  
      The long-tights-type leg support garment of the present invention shown in FIGS.  1  to  4  includes a stretchable part having a relatively great straining force, which includes a portion  2  expressed as the stretchable portion (A) having a relatively great straining force that is composed of a stretchable portion (A 1 )  121  having a relatively great straining force. The stretchable portion (A 1 )  121  having a relatively great straining force substantially covers the ligamentum collateralle  3  on the medial side of the knee joint of the human body, extends approximately along the vicinity of a periphery of the patella  1  on the medial side thereof so as to surround the patella  1  through not less than approximately ¼ (here, approximately 1.7/4) of the periphery of the patella  1  and to cover a part of an inferior region  4  of the patella  1 , reaches a side  5  of the musculus gastrocnemius and the musculus soleus on the medial side, and on the superior side of the knee joint, extends from the medial side to the lateral side of the thigh via the anterior side thereof approximately along the musculus sartorius  6  toward the vicinity of the trochanter major  8 , passing a superior part  7  of the musculus rectus femoris.  
      According to the foregoing preferred embodiment of the present invention, the stretchable portion  121  having a relatively great straining force covers a portion  4  of a part of an inferior region of the patella  1  so as to support the patella  1  as if pulling up the same from the inferior side, thereby improving the stability of the knee joint. The portion  121  further supports the musculus sartorius  6  and extends from the medial side to the lateral side of the thigh obliquely and spirally toward the vicinity of the trochanter major  8 , thereby increasing the power for pulling the stretchable portion having a relatively great straining force that supports the ligamentum collateralle medialis  3 . This makes it possible to provide a leg support garment having an increased power for supporting the ligamentum collateralle medialis  3 , and hence, this is preferable. Furthermore, this provides the support to the musculus sartorius  6  that complements the function of the ligamentum collateralle medialis  3  as well, which is also preferable.  
      FIGS.  5  to  8  are views illustrating another embodiment of a long-tights-type leg support garment of the present invention.  FIG. 5  is a rear view of the same,  FIG. 6  is a front view of the same,  FIG. 7  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 6 , and  FIG. 8  is a right-side view of the same.  
      The present embodiment differs from the embodiment shown in FIGS.  1  to  4  in the aspect that the portion  121  in the embodiment shown in FIGS.  1  to  4 , which is expressed as the stretchable portion (A 1 ) having a relatively great straining force, further includes a stretchable portion (A 1 - 1 )  122  having a relatively great straining force that extends from the vicinity of the trochanter major  8  to the vicinity of the waist  10  along the tractus iliotibialis  9 . Therefore, the same portions as those in the embodiment shown in FIGS.  1  to  4  are designated with the same reference numerals unless otherwise specified, and descriptions of the same are omitted. In the descriptions below as well, as to the embodiments shown in the drawings, the same portions as those in the other embodiments previously shown in the drawings are designated with the same reference numerals, and descriptions of the same are omitted.  
      Since the foregoing preferred embodiment of the present invention further includes the stretchable portion (A 1 - 1 )  122  having a relatively great straining force, which extends from the vicinity of the trochanter major  8  to the waist  10  along the tractus iliotibialis  9 , the same function as that explained with reference to FIGS.  1  to  4  is enhanced further, as well as the function of intensely pressing the trochanter major  8  is enhanced also, thereby improving the connection between the caput ossis femoris and the acetabulum. This is preferable since further providing a function of enhancing the stability of the hip joint.  
      Next, FIGS.  9  to  12  are views illustrating still another embodiment of a long-tights-type leg support garment of the present invention.  FIG. 9  is a rear view of the same,  FIG. 10  is a front view of the same,  FIG. 11  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 10 , and  FIG. 12  is a right-side view of the same.  
      The garment of the present embodiment is a garment as a modification of the embodiment shown in FIGS.  5  to  8 ; namely, the portion expressed as the stretchable portion (A 1 )  121  having a relatively great straining force further covers at least a part of a superior region  11  of the patella  1  by extending thereto approximately from a peripheral region of the patella  1  on the medial side of the patella  1 .  
      With the foregoing preferred embodiment of the present invention, the same function as that explained with reference to FIGS.  5  to  8  is exhibited. Besides, since the stretchable portion (A 1 )  121  having a relatively great straining force also covers at least a part of the superior region  11  of the patella  1 , the knee joint is supported therefrom as well as from the inferior region  4  of the patella  1 . Therefore, it allows more stability of the knee joint to be achieved, which is preferable.  
      Next, FIGS.  13  to  16  are views illustrating still another embodiment of a long-tights-type leg support garment of the present invention.  FIG. 13  is a rear view of the same,  FIG. 14  is a front view of the same,  FIG. 15  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 14 , and  FIG. 16  is a right-side view of the same.  
      The garment of the present embodiment is a garment as a modification of the embodiment shown in FIGS.  1  to  4 ; namely, the portion expressed as the stretchable portion (A 1 )  121  having a relatively great straining force further includes a stretchable portion (A 1 - 2 )  123  having a relatively great straining force. The stretchable portion (A 1 - 2 )  123  having a relatively great straining force extends obliquely upward from a side of the musculus gastrocnemius on the medial side through the vicinity of a periphery  12  of the patella on the inferior side of the patella to the lateral side  13  of the patella  1 .  
      With the foregoing preferred embodiment of the present invention, the same function as that explained with reference to FIGS.  1  to  4  is exhibited. Besides, the periphery of the patella  1  is covered from a side of the musculus gastrocnemius on the medial side, i.e., from the inferior medial side, and a power of pulling up the same in an obliquely upward direction is exerted thereto. Therefore, this provides more stability of the knee joint, and hence, the present embodiment is preferable.  
      Next, FIGS.  17  to  20  are views illustrating still another embodiment of a long-tights-type leg support garment of the present invention.  FIG. 17  is a rear view of the same,  FIG. 18  is a front view of the same,  FIG. 19  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 18 , and  FIG. 20  is a right-side view of the same.  
      The garment of the present embodiment is a garment as a modification of the embodiment shown in FIGS.  5  to  8 ; namely, to the garment shown in FIGS.  5  to  8 , a stretchable portion (B) having a relatively great straining force as described below is added. Namely, the garment further includes a stretchable portion (B)  124  having a relatively great straining force. The stretchable  143  (B)  124  having a relatively great straining force extends from a vicinity of the trochanter major  8  downward approximately along the tractus iliotibialis  9  to the lateral side of the patella  1 , covers a part of an inferior region  14  of the patella extending from the lateral side thereof, and passes a side  15  of the musculus gastrocnemius and the musculus soleus on the lateral side, thereby reaching the superior side  16  of the malleolus lateralis. The upper stretchable portion (A 1 - 1 )  122  having a relatively greater straining force has a slightly greater width as compared with that shown in FIGS.  5  to  8 , at a position where the stretchable portion (B)  124  having a relatively great straining force and the stretchable portion (A 1 )  121  having a relatively great straining force are united therewith.  
      With the foregoing preferred embodiment of the present invention, the same function as that explained with reference to FIGS.  5  to  8  is exhibited. Besides, since the stretchable portion (B)  124  having a relatively great straining force is further provided, the knee and leg are supported from the both sides at the femoral region and the lower leg region, and further, the musculus gastrocnemius and the musculus soleus are supported from their sides without hindering their actions. Furthermore, the function of pressing the trochanter major  8  is enhanced further, thereby improving the connection between the caput ossis femoris and the acetabulum. Therefore, this reinforces a function of enhancing the stability of the hip joint.  
      Next, FIGS.  21  to  24  are views illustrating still another embodiment of a long-tights-type leg support garment of the present invention.  FIG. 21  is a rear view of the same,  FIG. 22  is a front view of the same,  FIG. 23  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 22 , and  FIG. 24  is a right-side view of the same.  
      The garment of the present embodiment is a leg support garment in which the portion expressed as the stretchable portion (A) having a relatively great straining force is composed of a stretchable portion (A 2 )  130  having a relatively great straining force. The stretchable portion (A 2 )  130  having a relatively great straining force substantially covers the ligamentum collateralle  3  on the medial side of the knee joint of the human body, and extends approximately along a vicinity of a periphery of the patella  1  on the medial side thereof so as to surround the patella  1  through not less than approximately ¼ of the periphery of the patella  1  and to cover a part of an inferior region  4  of the patella  1 . Then, it reaches a side  5  of the musculus gastrocnemius and the musculus soleus on the medial side. Furthermore, on the superior side of the knee joint, the stretchable portion (A 2 ) having a relatively great straining force extends through the thigh approximately along the musculus semitendinosus  21  to the vicinity of the sulcus gluteus  22 .  
      The foregoing preferred embodiment allows the stretchable portion  130  having a relatively great straining force to cover a part of the inferior region  4  of the patella  1 , thereby support the patella  1  as if pulling up the patella  1  from the inferior side thereof As a result, the stability of the knee joint is improved. Furthermore, the embodiment allows the portion  130  to support the musculus semitendinosus  21  that is located on the medial side of the thigh, thereby increasing the power of pulling the stretchable portion having a relatively great straining force that supports the ligamentum collateralle medialis  3 . Consequently, a leg support garment with an increased power for supporting the ligamentum collateralle medialis  3  is provided, which is preferable. Furthermore, the musculus semitendinosus that complements the function of the ligamentum collateralle medialis is supported, which is also preferable.  
      Next, FIGS.  25  to  28  are views illustrating still another embodiment of a long-tights-type leg support garment of the present invention.  FIG. 25  is a rear view of the same,  FIG. 26  is a front view of the same,  FIG. 27  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 26 , and  FIG. 28  is a right-side view of the same.  
      The garment of the present embodiment is a leg support garment in which the portion expressed as the stretchable portion (A) having a relatively great straining force is composed of a stretchable portion (A 2 )  131  having a relatively great straining force. The stretchable portion (A 2 )  131  having a relatively great straining force substantially covers the ligamentum collateralle  3  on the medial side of the knee joint of the human body, and extends approximately along a vicinity of a periphery of the patella  1  on the medial side thereof so as to surround the patella  1  through not less than approximately ¼ of the periphery of the patella  1  and to cover a part of an inferior region  4  of the patella  1 . Then, it reaches a side  5  of the musculus gastrocnemius and the musculus soleus on the medial side. Furthermore, on the superior side of the knee joint, the portion (A 2 )  131  passes through the thigh approximately along the musculus gracilis  23 , and reaches the vicinity of the crotch  24 .  
      The foregoing preferred embodiment allows the stretchable portion  131  having a relatively great straining force to cover a part of the inferior region  4  of the patella  1 , thereby support the patella  1  as if pulling up the patella  1  from the inferior side thereof. As a result, the stability of the knee joint is improved. Furthermore, the embodiment allows the portion  131  to support the musculus gracilis  23  that is located on the medial side of the thigh, thereby increasing the power of pulling the stretchable portion having a relatively great straining force that supports the ligamentum collateralle medialis  3 . Consequently, a leg support garment with an increased power for supporting the ligamentum collateralle medialis  3  is provided, which is preferable. Furthermore, the musculus gracilis that complements the function of the ligamentum collateralle medialis is supported, which is preferable.  
      Next, FIGS.  29  to  32  are views illustrating still another embodiment of a long-tights-type leg support garment of the present invention.  FIG. 29  is a rear view of the same,  FIG. 30  is a front view of the same,  FIG. 31  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 30 , and  FIG. 32  is a right-side view of the same.  
      The garment of the present embodiment is a leg support garment in which the portion expressed as the stretchable portion (A) having a relatively great straining force is composed of the stretchable portion (A 2 )  132  having a relatively great straining force. The stretchable portion (A 2 )  132  substantially covers the ligamentum collateralle  3  on the medial side of the knee joint of the human body, and extends approximately along the vicinity of a periphery of the patella  1  on the medial side thereof so as to surround the patella  1  through not less than approximately ¼ of the periphery of the patella  1  and to cover a part of an inferior region  4  of the patella  1 . Then, it reaches a side  5  of the musculus gastrocnemius and the musculus soleus on the medial side. Further, on the superior side of the knee joint, the portion (A 2 )  132  passes through the thigh approximately along both  25  of the musculus semitendinosus and the musculus gracilis, and reaches the vicinity of the crotch  24  and the vicinity of the sulcus glutenus  22 .  
      The foregoing preferred embodiment allows the stretchable portion  132  having a relatively great straining force to cover a part of the inferior region  4  of the patella  1 , thereby support the patella  1  as if pulling up the patella  1  from the inferior side thereof As a result, the stability of the knee joint is improved. Furthermore, the embodiment allows the portion  132  to support both  25  of the musculus semitendinosus and the musculus gracilis that are located on the medial side of the thigh, thereby increasing the power of pulling the stretchable portion having a relatively great straining force that supports the ligamentum collateralle medialis  3 . Consequently, a leg support garment with an increased power for supporting the ligamentum collateralle medialis  3  is provided, which is preferable. Furthermore, both of the musculus semitendinosus and the musculus gracilis that complement the function of the ligamentum collateralle medialis are supported, which is also preferable.  
      Next, FIGS.  33  to  36  are views illustrating still another embodiment of a long-tights-type leg support garment of the present invention.  FIG. 33  is a rear view of the same,  FIG. 34  is a front view of the same,  FIG. 35  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 34 , and  FIG. 36  is a right-side view of the same.  
      The garment of the present embodiment is a leg support garment in which the portion expressed as the stretchable portion (A) having a relatively great straining force is composed of a stretchable portion (A 3 )  133  having a relatively great straining force. The stretchable portion (A 3 )  133  having a relatively great straining force substantially covers the ligamentum collateralle  3  on the medial side of the knee joint of the human body, and extends approximately along a vicinity of a periphery of the patella  1  on the medial side thereof so as to surround the patella through not less than approximately ¼ of the periphery of the patella  1  and to cover a part of an inferior region  4  of the patella  1 . Then, it reaches a side  5  of the musculus gastrocnemius and the musculus soleus on the medial side. Further, on the superior side of the knee joint, the portion (A 3 )  133  extends upward from the medial side to the lateral side of the thigh via the posterior side thereof approximately along the musculus semitendinosus and the musculus semimembranosus  26  to a vicinity of the trochanter major  8 , passing over the musculus biceps femoris  27  obliquely.  
      According to the foregoing preferred embodiment, the stretchable portion (A 3 )  133  having a relatively great straining force is provided, which extends from the side  5  of the musculus gastrocnemius and the musculus soleus on the medial side upwards, then passes the thigh obliquely in a spiral form from the medial side to the lateral side thereof via the posterior side thereof, and reaches the vicinity of the trochanter major  8 . Therefore, it is possible to support the patella  1  as if pulling up the same from the inferior side thereof, thereby improving the stability of the knee joint. Furthermore, it is also possible to increase the power of pulling the stretchable portion having a relatively great straining force that supports the ligamentum collateralle medialis  3 . Consequently, a leg support garment with an increased power for supporting the ligamentum collateralle medialis  3  is provided, which is preferable. Furthermore, both of the musculus semitendinosus and the musculus semimembranosus that complement the function of the ligamentum collateralle medialis are supported, which is preferable.  
      Next, FIGS.  37  to  40  are views illustrating still another embodiment of a long-tights-type leg support garment of the present invention.  FIG. 37  is a rear view of the same,  FIG. 38  is a front view of the same,  FIG. 39  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 38 , and  FIG. 40  is a right-side view of the same.  
      The garment of the present embodiment has characteristics of both the garment shown in FIGS.  5  to  8  and that of FIGS.  21  to  24 . More specifically, the portion expressed as the stretchable portion (A) having a relatively great straining force includes a stretchable portion (A)  121  having a relatively great straining force and a stretchable portion (A 1 - 1 )  122  having a relatively great straining force, as well as a stretchable portion (A 2 ′)  140  having a relatively great straining force. The stretchable portion (A)  121  having a relatively great straining force substantially covers the ligamentum collateralle  3  on the medial side of the knee joint of the human body, extends approximately along the vicinity of a periphery of the patella  1  on the medial side thereof so as to surround the patella  1  through not less than approximately ¼ (here, approximately 1.7/4) of the periphery of the patella  1  and to cover a part of an inferior region  4  of the patella  1 , reaches a side  5  of the musculus gastrocnemius and the musculus soleus on the medial side, and on the superior side of the knee joint, extends from the medial side to the lateral side of the thigh via the anterior side thereof approximately along the musculus sartorius  6  to a superior region  7  of the musculus rectus femoris and the vicinity of the trochanter major  8  [(A 1 )  122 ]. The stretchable portion (A 1 - 1 )  122  having a relatively great straining force extends from the vicinity of the trochanter major  8  along the tractus iliotibialis  9  to the vicinity of the waist  10 . On the superior side of the knee-joint-part of the stretchable portion (A)  121  having a relatively great straining force, the stretchable portion (A 2 ′)  140  having a relatively great straining force is also arranged extending from a divergence point  31  through the thigh approximately along the musculus semitendinosus  21  to the vicinity of the sulcus gluteus  22 .  
      According to the foregoing preferred embodiment of the present invention, the stretchable portions (A 1 )  121  and (A 1 - 1 )  122  having relatively great straining forces are present in a spiral form, extending obliquely from the medial side to the lateral side of the thigh, then, over the trochanter major  8  to the vicinity of the waist  10 . In addition, the stretchable portion (A 2 ′)  140  having a relatively great straining force that branches therefrom on the superior side of the knee joint is present also, extending through the thigh approximately along the musculus semitendinosus  21  to the vicinity of the sulcus gluteus  22 . The actions of these in combination further increase the power of pulling the stretchable portion having a relatively great straining force that supports the ligamentum collateralle medialis  3 . Consequently, a leg support garment with an increased power for supporting the ligamentum collateralle medialis  3  is provided, which is preferable. Furthermore, not only the musculus sartorius  6  but also the musculus semitendinosus  21  that complement the function of the ligamentum collateralle medialis  3  are supported, which is preferable. Furthermore, the stretchable portion (A 1 - 1 )  122  having a relatively great straining force that is provided from the vicinity of the trochanter major  8  to the vicinity of the waist  10  along the tractus iliotibialis  9  provides a function of pressing the trochanter major, thereby improving the connection between the caput ossis femoris and the acetabulum. Therefore, this further provides a function of enhancing the stability of the hip joint, which is preferable.  
      Next, FIGS.  41  to  44  are views illustrating still another embodiment of a long-tights-type leg support garment of the present invention.  FIG. 41  is a rear view of the same,  FIG. 42  is a front view of the same,  FIG. 43  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 42 , and  FIG. 44  is a right-side view of the same.  
      The garment of the present embodiment has characteristics of both the garment shown in FIGS.  5  to  8  and that of FIGS.  25  to  28 . More specifically, a portion expressed as the stretchable portion (A) having a relatively great straining force includes a stretchable portion (A)  121  having a relatively great straining force and a stretchable portion (A 1 - 1 )  122  having a relatively great straining force, as well as a stretchable portion (A 2 ′)  141  having a relatively great straining force. The stretchable portion (A)  121  having a relatively great straining force substantially covers the ligamentum collateralle  3  on the medial side of the knee joint of the human body, extends approximately along the vicinity of a periphery of the patella  1  on the medial side thereof so as to surround the patella  1  through not less than approximately ¼ (here, approximately 1.7/4) of the periphery of the patella  1  and to cover a part of an inferior region  4  of the patella  1 , reaches a side  5  of the musculus gastrocnemius and the musculus soleus on the medial side, and on the superior side of the knee joint, extends from the medial side to the lateral side of the thigh via the anterior side thereof approximately along the musculus sartorius  6  to a superior region  7  of the musculus rectus femoris and the vicinity of the trochanter major  8 . The stretchable portion (A 1 - 1 )  122  having a relatively great straining force extends from the vicinity of the trochanter major  8  along the tractus iliotibialis  9  to the vicinity of the waist  10 . On the superior side of the knee-joint-part of the stretchable portion (A)  121  having a relatively great straining force, the stretchable portion (A 2 ′)  141  having a relatively great straining force is also arranged extending from a divergence point  31  through the thigh approximately along the musculus gracilis  23  to the vicinity of the crotch  24 .  
      According to the foregoing preferred embodiment of the present invention, the stretchable portions (A 1 )  121  and (A 1 - 1 )  122  having relatively great straining forces are present in a spiral form, extending obliquely from the medial side to the lateral side of the thigh, then, over the trochanter major  8  to the vicinity of the waist  10 . In addition, the stretchable portion (A 2 ′)  141  having a relatively great straining force that branches therefrom on the superior side of the knee joint is present, extending through the thigh approximately along the musculus gracilis  23  to the vicinity of the crotch  24 . The actions of these in combination increases the power of pulling the stretchable portion having a relatively great straining force that supports the ligamentum collateralle medialis  3 . Consequently, a leg support garment with an increased power for supporting the ligamentum collateralle medialis  3  is provided, which is preferable. Furthermore, not only the musculus sartorius  6  but also the musculus gracilis  23  that complement the function of the ligamentum collateralle medialis  3  are also supported, which is preferable. Furthermore, the stretchable portion (A 1 - 1 )  122  having a relatively great straining force that is provided from the vicinity of the trochanter major  8  to the vicinity of the waist  10  along the tractus iliotibialis  9  provides a function of pressing the trochanter major, thereby improving the connection between the caput ossis femoris and the acetabulum. Therefore, this further provides a function of enhancing the stability of the hip joint, which is preferable.  
      Next, FIGS.  45  to  48  are views illustrating still another embodiment of a long-tights-type leg support garment of the present invention.  FIG. 45  is a rear view of the same,  FIG. 46  is a front view of the same,  FIG. 47  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 46 , and  FIG. 48  is a right-side view of the same.  
      The garment of the present embodiment is a leg support garment in which the portion expressed as the stretchable portion (A) having a relatively great straining force is a stretchable portion (A 2 ′)  142  having a relatively great straining force, and the stretchable part having a relatively great straining force further includes a stretchable portion (B′)  143  having a relatively great straining force. The stretchable portion (A 2 ′)  142  having a relatively great straining force substantially covers the ligamentum collateralle  3  on the medial side of the knee joint of the human body, extends approximately along a vicinity of a periphery of the patella  1  on the medial side thereof so as to surround the patella  1  through at least more than approximately ½ of the periphery of the patella  1  and to cover a part of inferior and superior regions  4  and  11  of the patella, and reaches a side  5  of the musculus gastrocnemius and the musculus soleus on the medial side. Further, on the superior side of the knee joint, in the femoral region, the stretchable portion (A 2 ′)  142  having a relatively great straining force extends approximately along the musculus semitendinosus and the musculus gracilis, and reaches the vicinity below the crotch  24  and a vicinity of the sulcus gluteus  22 . The stretchable portion (B′)  143  having a relatively great straining force extends from a side part of the waist  10  approximately along the tractus iliotibialis  9  via a vicinity of the trochanter major  8 , then, approximately along the tractus iliotibialis  9  to the lateral side of the patella  1 , surrounds the patella  1  through approximately ½ or more of the periphery of the patella  1  so as to cover a part of an inferior region  32  and a superior region  33  of the patella  1 , and passes a side  15  of the musculus gastrocnemius and the musculus soleus on the lateral side.  
      In the foregoing embodiment, two portions  4  and  11  of the stretchable portion (A 2 ′)  142  having relatively great straining forces project toward the medial side therefrom and cover a part of the inferior region  4  and a part of the superior region  11  of the patella  1 , respectively. Besides, two portions  32  and  33  of the stretchable portion (B′)  143  having relatively great straining forces project toward the lateral side therefrom and cover a part of the inferior region  32  and a part of the superior region  33  of the patella  1 , respectively. Here, the two portions  4  and  11  of the stretchable portion (A 2 ′)  142  having a relatively great straining force are arranged opposite to the two portions  32  and  33  of the stretchable portion (B′)  143  having a relatively great straining force, respectively, and at positions slightly shifted to the inferior side from positions of the portions  32  and  33  of the stretchable portion (B′)  143  having a relatively great straining force, respectively. Furthermore, when viewed from the front, the portion covering the inferior region  4  of the patella  1 , of the stretchable portion (A 2 ′)  142  having a relatively great straining force, has a relatively greater area.  
      The foregoing preferred embodiment allows the stretchable portions having relatively great straining forces to support the knee and leg from both sides in the femoral region and the lower leg region, without hindering the action of the musculus vastus lateralis and the musculus vastus medialis on the anterior side of the thigh, :and further, allows the knee joint to be supported as if wrapped from the surrounding, thereby providing further support of the knee joint. Besides, the function of pressing the trochanter major  8  is reinforced, thereby further improving the connection between the caput ossis femoris and the acetabulum. Therefore, the function of enhancing the stability of the hip joint is reinforced, which is preferable.  
      Furthermore, in the lower leg region, on the medial side, the muscles are fewer and the tibia is in contact with the surface of the body. On the other hand, on the lateral side of the lower leg region, the musculus gastrocnemius is on the lateral side of the fibula. Therefore, the foregoing embodiment provides the support of the knee joint as if pulling the medial side thereof having fewer muscles more intensely from the inferior side, thereby reinforcing the support of the ligamentum collateralle medialis, which is preferable.  
      As described above, in the foregoing embodiment, as to the two portions  4  and  11  of the stretchable portion (A 2 ′)  142  having a relatively great straining force that project to the lateral side and cover a part of the inferior region  4  and a part of the superior region  11  of the patella  1 , respectively, and the two portions  32  and  33  of the stretchable portion (B′)  143  having a relatively great straining force that project to the medial side and cover a part of the inferior region  32  and a part of the superior region  33  of the patella  1 , respectively, the position of the projecting portion  4  is slightly inferior to the position of the projecting portion  32 , and the position of the projecting portion  11  is slightly inferior to the position of the projecting portion  32 . Therefore, this provides the support of the knee joint as if pulling the medial side thereof having fewer muscles more intensely from the inferior side, thereby reinforcing the support of the ligamentum collateralle medialis, which is preferable. However, the projecting portion  4  may be at a position as high as the position of the projecting portion  32 , or the projecting portion  11  may be at a position as high as a position of the projecting portion  33 . Besides, the two portions  4  and  11  projecting toward the lateral side may further extend over the central line of the anterior side of the leg toward the lateral side, while the portions  32  and  33  opposite thereto may further extend over the central line of the anterior side of the leg toward the medial side. Alternatively, the projecting portions  4  and  32  may be connected with each other, and likewise, the projecting portions  11  and  33  may be connected with each other. Furthermore, the projecting portion  4  may be located at a position shifted slightly to the superior side of the projecting portion  32 , while the projecting portion  11  may be located at a position shifted slightly to the superior side of the projecting portion  33 .  
      Next, FIGS.  49  to  52  are views illustrating still another embodiment of a long-tights-type leg support garment of the present invention.  FIG. 49  is a rear view of the same,  FIG. 50  is a front view of the same,  FIG. 51  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 50 , and  FIG. 52  is a right-side view of the same.  
      The garment of the present embodiment is a garment as a modification of the embodiment shown in FIGS.  17  to  20 ; namely, to the garment shown in FIGS.  17  to  20 , stretchable portions having relatively great straining forces obtained by modifying a stretchable portion (C) having a relatively great straining force and a stretchable portion (D) having a relatively great straining force, respectively, are added as described below. Therefore, the same portions as those in the embodiment shown in FIGS.  17  to  20  are designated with the same reference numerals, and descriptions of the same are omitted. However, the portions substantially the same as those shown in FIGS.  17  to  20  still have a slight difference. Namely, the stretchable portion (B)  124  having a relatively great straining force shown in FIGS.  17  to  20  reaches to the superior side  16  of the malleolus lateralis, while a stretchable portion (B)  124 ′ having a relatively great straining force shown in FIGS.  49  to  52  reaches only the side  15  of the musculus gastrocnemius and the musculus soleus on the lateral side, and does not reach the superior side  16  of the malleolus lateralis.  
      The other aspects are substantially the same as those of the embodiment of the garment shown in FIGS.  17  to  20 , and stretchable portions having relatively great straining forces described below are further provided.  
      There are provided a stretchable portion (C)  145  having a relatively great straining force and a stretchable portion  146  having a relatively great straining force. The stretchable portion (C)  145  having a relatively great straining force includes right and left parts that are connected at a position  35  corresponding to the fourth lumbar vertebra to the os sacrum on the posterior side of the human body, and covers a region extending from the foregoing position  35 , through an approximately middle part of the musculus gluteus maximus at right and left, approximately in a direction along muscular fibers of the musculus gluteus maximus via the top of the bulge of the hip or the vicinity of the same to at least the vicinity of trochanter major. The stretchable portion  146  having a relatively great straining force includes right and left parts that are connected approximately in the vicinity of the posterior central position of the waist, and covers a region extending from the vicinity of the posterior central position of the waist to at least the flank at right and left, in contact with a part of the musculus latissimus dorsi, the musculus gluteus medius, and the musculus obliquus externus abdominis. Therefore, the stretchable portion (C)  145  having a relatively great straining force provides the firm support of the musculus gluteus maximus in the muscular fiber direction thereof. Thus, it can play a large role in supporting the rotating motion of the hips, preventing a decrease in the rotating angle of the hips, and stabilizing the pelvis in anterior-posterior direction. For an elderly person, it is effective in preventing falling down. Furthermore, it can play a large role in extending the hip joint in anterior-posterior direction when running, jumping, and climbing up a slope. Moreover, the stretchable portion  146  having a relatively great straining force provides the firmer support of a region from the posterior central position of the waist to the musculus latissimus dorsi, the musculus gluteus medius, and the musculus obliquus externus abdominis at right and left. Consequently, a function for complementing the function of preventing backward inclination of the pelvis and keeping a stable position of the pelvis is displayed.  
      Furthermore, the garment of the present embodiment includes a stretchable portion (D)  147  having a relatively great straining force and a stretchable portion  148  having a relatively great straining force. The stretchable portion (D)  147  having a relatively great straining force includes right and left parts that are connected with each other on the musculus rectus abdominis  36  in the abdominal region, and covers a region extending from a position on the musculus rectus abdominis in the hypogastric region, obliquely downward approximately in a direction along muscular fibers of the musculus obliquus internus abdominis to the vicinity of the trochanter major  8  at right and left. The stretchable portion  148  having a relatively great straining force includes light and left parts that are connected with each other on the musculus rectus abdominis  36  in the hypogastric region, and covers a region extending from a position on the musculus rectus abdominis  36 , obliquely upward approximately in a direction along muscular fibers of the musculus obliquus externus abdominis to at least the flank.  
      Therefore, the stretchable portion (D)  147  having a relatively great straining force supports a part of the musculus rectus abdominis and the musculus obliquus internus abdominis, thereby providing functions of reducing lumbar lordosis, maintaining good posture, making youthful figure, and preventing generation of pains such as lumbar pains. Furthermore, the stretchable portion  148  having a relatively great straining force supports a part of the musculus rectus abdominis and the musculus obliquus externus abdominis, thereby providing functions of reducing lumbar lordosis, maintaining good posture, making youthful figure, and preventing generation of pains such as lumbar pains.  
      It should be noted that such portions (C)  145 ,  146 , (D)  147 , and  148  are applicable to the stretchable part having a relatively great straining force in the other embodiments as required.  
      Next, FIGS.  53  to  56  are views illustrating still another embodiment of a long-tights-type leg support garment of the present invention.  FIG. 53  is a rear view of the same,  FIG. 54  is a front view of the same,  FIG. 55  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 54 , and  FIG. 56  is a right-side view of the same.  
      In the garment of the present embodiment is substantially the same as the leg support garment shown in FIGS.  1  to  4  in the aspect of the stretchable portion having a relatively great straining force that extends upward from the ligamentum collateralle  3  on the medial side of the knee joint, but differs from the garment shown in FIGS.  1  to  4  in the aspect of the stretchable portion having a relatively great straining force that extends downward therefrom. More specifically, the portion  2  expressed as the stretchable portion (A) having a relatively great straining force that substantially covers the ligamentum collateralle  3  on the medial side of the knee joint of the human body, and extends approximately along a vicinity of a periphery of the patella  1  on the medial side thereof so as to surround the patella through not less than approximately ¼ (here, approximately 1.7/4) of the periphery of the patella  1  and to cover a part of an inferior region  4  of the patella  1 . On the other hand, a stretchable portion  150  having a relatively great straining force that extends downward therefrom extends obliquely through the anterior side of the lower leg region to the lateral side in a direction toward the malleolus lateralis  16 ′. The stretchable portion  150  having a relatively great straining force, on the superior side of the knee joint, extends from the medial side to the lateral side of the thigh via the anterior side thereof approximately along the musculus sartorius  6  to a vicinity of the trochanter major  8 , passing a superior part  7  of the musculus rectus femoris.  
      Therefore, the portion on the superior side of the knee joint displays the same function as that in the case of FIGS.  1  to  4 , and the straining force is exerted to both of the superior and inferior parts of the ligamentum collateralle medialis  3  so as to pull up the same obliquely outward. Therefore, this provides the firmer support of the ligamentum collateralle medialis  3 .  
      Next, FIGS.  57  to  60  are views illustrating still another embodiment of a long-tights-type leg support garment of the present invention.  FIG. 57  is a rear view of the same,  FIG. 58  is a front view of the same,  FIG. 59  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 58 , and  FIG. 60  is a right-side view of the same.  
      The garment of the present embodiment resembles the garment shown in FIGS.  13  to  16  in the aspect that a stretchable portion  151  having a relatively great straining force surrounds the inferior side of the patella  1 . The former differs from the latter in the following aspect. Namely, the stretchable portion having a relatively great straining force extends obliquely upward from a side of the musculus gastrocnemius on the medial side through the vicinity  12  of the inferior side of the patella, further upward via the lateral side  13  of the patella  1  along the musculus vastus lateralis  37  and the tractus iliotibialis  9 , and join in at a junction point  38  with a stretchable portion having a relatively great straining force that extends from the medial side to the lateral side of the thigh via the anterior side thereof approximately along the musculus sartorius  6  to a vicinity of the trochanter major  8 , passing a superior part  7  of the musculus rectus femoris, and further, along the tractus iliotibialis  9  to the vicinity of the waist  10 .  
      The foregoing embodiment allows the garment to display the same function as that of the garment shown in FIGS.  13  to  16 , and to provide more stable support of the knee joint. Besides, as compared with the garment shown in FIGS.  13  to  16 , the garment of the present embodiment further includes the stretchable portion having a relatively great straining force that extends from the vicinity of the trochanter major  8  along the tractus iliotibialis  9  to the vicinity of the waist  10 . Therefore, the function of intensely pressing the trochanter major  8  is enhanced also, thereby improving the connection between the caput ossis femoris and the acetabulum. Therefore, this further provides a function of enhancing the stability of the hip joint. Thus, the present embodiment is preferable.  
      Next, FIGS.  61  to  64  are views illustrating still another embodiment of a long-tights-type leg support garment of the present invention.  FIG. 61  is a rear view of the same,  FIG. 62  is a front view of the same,  FIG. 63  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 62 , and  FIG. 64  is a right-side view of the same.  
      The garment of the present embodiment is a modification of the embodiment shown in FIGS.  57  to  60 ; namely, the stretchable portion  151  having a relatively great straining force in the embodiment shown in FIGS.  57  to  60  further includes a stretchable portion  152  having a relatively great straining force that extends from a junction position  39  downward, passes a side of the musculus gastrocnemius and the musculus soleus on the lateral side, then reaches the superior side  16  of the malleolus lateralis.  
      With the foregoing embodiment, the same function as that of the garment shown in FIGS.  57  to  60  is displayed, and further, the musculus gastrocnemius and the musculus soleus are supported from their sides without hindering their actions. Thus, the foregoing embodiment is preferable.  
      Next, FIGS.  65  to  68  are views illustrating still another embodiment of a long-tights-type leg support garment of the present invention.  FIG. 65  is a rear view of the same,  FIG. 66  is a front view of the same,  FIG. 67  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 66 , and  FIG. 68  is a right-side view of the same.  
      The garment of the present embodiment is a modification of the embodiment shown in FIGS.  13  to  16 . This is characterized in that a stretchable portion  153  having a relative great straining force completely surrounds the patella  1 . This further enhances the stability of the knee. It should be noted that the other aspects other than the stretchable portion  153  having a relative great straining force are the same as those of the stretchable part having a relatively great straining force shown in FIGS.  13  to  16 .  
      The foregoing embodiment allows the garment to display the same function as that of the garment shown in FIGS.  13  to  16 , and further provides the more stable support of the knee joint.  
      Next, FIGS.  69  to  72  are views illustrating still another embodiment of a long-tights-type leg support garment of the present invention.  FIG. 69  is a rear view of the same,  FIG. 70  is a front view of the same,  FIG. 71  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 70 , and  FIG. 72  is a right-side view of the same.  
      The garment according to the present embodiment is a modification of the embodiment shown in FIGS.  1  to  4 . The garment of the present embodiment has the following characteristic common to the leg support garment shown in FIGS.  1  to  4 . The portion  2  expressed as the stretchable portion (A) having a relatively great straining force that is composed of a stretchable portion (A 1 )  121  having a relatively great straining force. The stretchable portion (A 1 )  121  having a relatively great straining force substantially covers the ligamentum collateralle  3  on the medial side of the knee joint of the human body, extends approximately along the vicinity of a periphery of the patella  1  on the medial side thereof so as to surround the patella  1  through not less than approximately ¼ (here, approximately 1.7/4) of the periphery of the patella  1  and to cover a part of an inferior region  4  of the patella  1 , reaches a side  5  of the musculus gastrocnemius and the musculus soleus on the medial side, and on the superior side of the knee joint, extends from the medial side to the lateral side of the thigh via the anterior side thereof approximately along the musculus sartorius  6  toward the vicinity of the trochanter major  8 , passing a superior part  7  of the musculus rectus femoris. In the present embodiment, however, a triangle-shaped stretchable portion  154  having a relatively great straining force is further provided on the lateral inferior side of the patella  1 , and the vertex of the projecting portion  4  having a relatively great straining force covering the inferior region of the patella  1  of the stretchable portion  121  having a relatively great straining force is in contact with a vertex  40  of the stretchable portion  154  having a relatively great straining force at a position on the inferior side of the patella  1  so as to support the knee from the right, left, and inferior sides. Therefore, the same function as that of the leg support garment shown in FIGS.  1  to  4  is exhibited, while the function of supporting the knee from the inferior side is reinforced. It should be noted that the projecting portion  4  of the stretchable portion having a relatively great straining force that covers the inferior region  4  of the patella  1  and the stretchable portion  154  having a relatively great straining force may overlap each other, rather than only with the vertex of the former and the vertex  40  of the latter being in contact with each other.  
      Next, FIGS.  73  to  76  are views illustrating still another embodiment of a long-tights-type leg support garment of the present invention.  FIG. 73  is a rear view of the same,  FIG. 74  is a front view of the same,  FIG. 75  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 74 , and  FIG. 76  is a right-side view of the same.  
      The garment of the present embodiment is a garment as a modification of the embodiment shown in FIGS.  5  to  8 ; namely, the portion  2  expressed as the stretchable portion (A) having a relatively great straining force includes a stretchable portion  122 ′ having a relatively great straining force that resembles a combination of the stretchable portions  121  and  122  having relatively great straining forces. The stretchable portion  122 ′ substantially covers the ligamentum collateralle  3  on the medial side of the knee joint of the human body, extends approximately along the vicinity of a periphery of the patella  1  on the medial side thereof so as to surround the patella  1  through not less than approximately ¼ (here, approximately 1.7/4) of the periphery of the patella  1  and to cover a part of an inferior region  4  of the patella  1 , and reaches a side  5  of the musculus gastrocnemius and the musculus soleus on the medial side. Then, from the side  5  of the musculus gastrocnemius and the musculus soleus on the medial side, the portion  122 ′ passes a side  41  of an inferior part of the musculus gastrocnemius and the musculus soleus on the medial side to a superior side  42  of the malleolus medialis. On the superior side of the knee joint, the portion  122 ′ extends from the medial side to the lateral side of the thigh via the anterior side thereof approximately along the musculus sartorius  6  toward the vicinity of the trochanter major  8 , passing a superior part  7  of the musculus rectus femoris. Further, the portion  122 ′ extends therefrom along the tractus iliotibialis  9  to the vicinity of the waist  10 . The stretchable portion  122 ′ having the relatively great straining force slightly differs from the combination of the stretchable portions  121  and  122  having relatively great straining forces in the aspect that the former further extends from the side  5  of the musculus gastrocnemius and the musculus soleus via the inferior side  41  of the musculus gastrocnemius and the musculus soleus to the superior side  42  of the malleolus medialis.  
      In the present embodiment, furthermore, a stretchable portion  155  having a relatively great straining force is provided, which extends from the superior side of the patella  1  via the lateral side thereof, covers an inferior region  32  of the patella, and further, passes a side  43  of the musculus gastrocnemius and the musculus soleus on the lateral side downward to a superior side  16  of the malleolus lateralis.  
      Therefore, the same function as that of the garment of the embodiment shown in FIGS.  5  to  8  is displayed, and further, since the foregoing garment supports the knee joint from the medial and lateral sides, it provides the more stable support of the knee joint. Moreover, since the stretchable portions having relatively great straining forces passes along both the medial and lateral sides of the musculus gastrocnemius and the musculus soleus, they support these musculus without hindering their actions. Thus, the foregoing embodiment is preferable.  
      Next, FIGS.  77  to  80  are views illustrating still another embodiment of a long-tights-type leg support garment of the present invention.  FIG. 77  is a rear view of the same,  FIG. 78  is a front view of the same,  FIG. 79  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 78 , and  FIG. 80  is a right-side view of the same.  
      The garment of the present embodiment is a garment as a modification of the embodiment shown in FIGS.  9  to  12 ; namely, the portion  2  expressed as the stretchable portion (A) having a relatively great straining force includes a stretchable portion  156  having a relatively great straining force that resembles a combination of the stretchable portions  121  and  122  having relatively great straining forces. The stretchable portion  156  having a relatively great straining force substantially covers the ligamentum collateralle  3  on the medial side of the knee joint of the human body, extends approximately along the vicinity of a periphery of the patella  1  on the medial side thereof so as to surround the patella  1  through not less than approximately ¼ (here, approximately 1.7/4) of the periphery of the patella  1  and to cover a part of an inferior region  4  and a superior region  11  of the patella  1 . Then, from a side  5  of the musculus gastrocnemius and the musculus soleus on the medial side, the portion  156  extends via a side  41  of an inferior part of the musculus gastrocnemius and the musculus soleus on the medial side to a superior side  42  of the malleolus medialis. On the superior side of the knee joint, the portion  156  extends from the medial side to the lateral side of the thigh via the anterior side thereof approximately along the musculus sartorius  6  toward the vicinity of the trochanter major  8 , passing a superior part  7  of the musculus rectus femoris. Further, the portion  156  extends therefrom along the tractus iliotibialis  9  to the vicinity of the waist  10 . The stretchable portion  156  having the relatively great straining force slightly differs from the combination of the stretchable portions  121  and  122  having relatively great straining forces in the aspect that the medial inferior part of the former extends from the side  5  of the musculus gastrocnemius and the musculus soleus via a side  41  of an inferior part of the musculus gastrocnemius and the musculus soleus to a superior side  42  of the malleolus medialis.  
      Moreover, the garment of the present embodiment greatly differs from the garment shown in FIGS.  9  to  12  in the aspect that the stretchable portion  156  having a relatively great straining force branches out at a divergence point  44  and further covers a region extending therefrom downward along a lateral side of the leg to the malleolus lateralis  16 . More specifically, the stretchable portion  156  having a relatively great straining force further extends from the divergence point  44  approximately along the tractus iliotibialis  9  to the lateral side of the patella  1 , then, approximately along a vicinity of a periphery of the patella  1  on a lateral side thereof so as to surround the patella through approximately ½ or more of the periphery of the patella and to cover a part of and inferior region  32  and a superior region  33  of the patella  1 . Then, it extends downward along a side  43  of the musculus gastrocnemius and the musculus soleus on the lateral side to the superior side  16  of the malleolus lateralis.  
      The foregoing preferred embodiment of the present invention allows the same function as that of the garment of the embodiment shown in FIGS.  9  to  12  to be displayed. Further, the power for pulling the stretchable portion having a relatively great straining force that supports the ligamentum collateralle medialis  3  is further increased, whereby the power for supporting the ligamentum collateralle medialis  3  is increased. Besides, since the knee joint is supported from both of the medial and lateral sides, this provides the more stable support of the knee joint. Moreover, since the stretchable portion having a relatively great straining force passes both of the medial and lateral sides of the musculus gastrocnemius and the musculus soleus, these muscles are supported without hindering their activities. Thus, the present embodiment is preferable.  
      Next, FIGS.  81  to  84  are views illustrating still another embodiment of a long-tights-type leg support garment of the present invention.  FIG. 81  is a rear view of the same,  FIG. 82  is a front view of the same,  FIG. 83  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 82 , and  FIG. 84  is a right-side view of the same.  
      The garment of the present embodiment is a garment as a modification of the embodiment shown in FIGS.  17  to  20 ; namely, in the garment of the embodiment shown in FIGS.  17  to  20 , the stretchable portion (A)  121  having a relatively great straining force and the stretchable portion  124 ′ (B) having a relatively great straining force are in contact with each other at a position on the inferior side of the patella. Therefore, the same portions as those shown in FIGS.  17  to  20  are designated with the same reference numerals in the drawings and descriptions of the same are omitted. However, substantially the same portions as those shown in FIGS.  17  to  20  still have slight differences; namely, the stretchable portion (B)  124  having a relatively great straining force reaches to the superior side  16  of the malleolus lateralis, while the stretchable portion (B)  124 ′ having a relatively great straining force of the embodiment shown in FIGS.  81  to  84  stops at a side  15  of the musculus gastrocnemius and the musculus soleus on the lateral side, not reaching the superior side  16  of the malleolus lateralis.  
      The aspects other than the above are substantially the same as those of the garment of the embodiment shown in FIGS.  17  to  20 .  
      More specifically, a vertex of a projecting portion  4  of the stretchable portion  121  having a relatively great straining force that covers a part of the inferior region of the patella  1  and a vertex of a projecting portion  14  of the stretchable portion  124 ′ having a relatively great straining force that covers a part of the inferior region of the patella  1  are in contact with each other at a position on the inferior side of the patella  1 , so as to support the knee from the right, left, and inferior sides of the same. Therefore, the same function as that of the leg support garment shown in FIGS.  17  to  20  is displayed, and the function of supporting the knee from the inferior side is reinforced.  
      Next, FIGS.  85  to  88  are views illustrating still another embodiment of a long-tights-type leg support garment of the present invention.  FIG. 85  is a rear view of the same,  FIG. 86  is a front view of the same,  FIG. 87  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 86 , and  FIG. 88  is a right-side view of the same.  
      The garment of the present embodiment is a garment as a modification of the embodiment shown in FIGS.  81  to  84 ; namely, in the garment of the embodiment shown in FIGS.  81  to  84 , the stretchable portion (A)  121  having a relatively great straining force and the stretchable portion (B)  124 ′ having a relatively great straining force are coupled with each other in a slightly wide range on the inferior side of the patella, rather than in point contact with each other. Therefore, the same portions as those of the embodiment shown in FIGS.  81  to  84  are designated with the same reference numerals in the drawings and descriptions of the same are omitted.  
      More specifically, a portion  4  of the stretchable portion  121  having a relatively great straining force that covers a part of the inferior region of the patella  1  and a portion  14  of the stretchable portion  124 ′ having a relatively great straining force that covers a part of the inferior region of the patella  1  are coupled with each other at a position on the inferior side of the patella  1 , so as to support the knee from the right, left, and inferior sides of the same. Therefore, the same function as that of the leg support garment shown in FIGS.  81  to  84  is displayed, and the function of supporting the knee from the inferior side is further reinforced.  
      It should be noted that in the case of the present embodiment, in the case where the stretchable part having a relatively great straining force is formed by laminating stretchable fabrics in predetermined shapes on a garment main body and sewing them, or the like, the coupling between the portion  4  of the stretchable portion  121  having a relatively great straining force that covers a part of the inferior region of the patella  1  and the portion  14  of the stretchable portion  124 ′ having a relatively great straining force that covers a part of the inferior region of the patella  1  may be achieved by forming the same with one piece of fabric in which the stretchable portions  121  and  124 ′ having relatively great straining forces are continuously provided, so that the coupling therebetween has been achieved beforehand. Alternatively, the stretchable portions  121  and  124 ′ having relatively great straining forces may be made of separate pieces of fabrics, respectively, and portions of the fabrics corresponding to the portions  4  and  14  may be overlapped and sewn so that the coupling therebetween is achieved.  
      So far the present invention has been described with reference to specific examples of the long-tights-type leg support garment, but any design of a garment in which an upper body part is added to the long-tights-type leg support garment of the present invention as required is not excluded from the present invention at all, as long as the object of the present invention is not inhibited.  
      The following description will explain embodiments of a tights-type leg support garment having a length capable of covering a range from a waistline to the inferior side of the knee (a garment of this kind is hereinafter referred to as “semi-long-tights-type garment” also) while referring to the drawings. Meanwhile, “having a length capable of covering at least a range to the inferior side of the knee” described above means that the garment reaches at least the inferior end of the patella or a position below the same, and preferably, the garment has a hem line at a position at least 3  3  cm to 5 cm below the inferior end of the patella. Furthermore, though not particularly limited, the garment preferably has its lowest end at a middle position of the lower leg below the knee or above the same. However, the present invention does not exclude any garment having a hemline at a position below the same.  
      FIGS.  89  to  92  are views illustrating an embodiment of a semi-long-tights-type leg support garment of the present invention.  FIG. 89  is a rear view of the same,  FIG. 90  is a front view of the same,  FIG. 91  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 90 , and  FIG. 92  is a right-side view of the same.  
      The garment of the present embodiment is equivalent to a semi-long-tights-type leg support garment obtained by, from the long-tights-type leg support garment shown in FIGS.  5  to  8 , cutting away a part lower than a position of the portion  4  of the stretchable portion  121  having a relatively great straining force that covers the inferior region of the patella  1 .  
      More specifically, a portion  2  expressed as the stretchable portion (A) having a relatively great straining force includes a stretchable portion (A 2   1 )  121   a  having a relatively great straining force and a stretchable portion (A 2   1 - 1 )  122   a  having a relatively great straining force. The stretchable portion (A 2   1 )  121   a  having a relatively great straining force substantially covers the ligamentum collateralle  3  on the medial side of the knee joint of the human body, extends approximately along the vicinity of a periphery of the patella  1  on the medial side thereof so as to surround the patella  1  through not less than approximately ¼ (here, approximately 1.7/4) of the periphery of the patella  1  and to cover a part of an inferior region  4  of the patella  1 , and on the superior side of the knee joint, extends from the medial side to the lateral side of the thigh via the anterior side thereof approximately along the musculus sartorius  6  toward the vicinity of the trochanter major  8 , passing a superior part  7  of the musculus rectus femoris. The stretchable portion (A 2   1 - 1 )  122   a  having a relatively great straining force extends from the vicinity of the trochanter major  8  to the vicinity of the waist  10  along the tractus iliotibialis  9 . The lower end of the hemline in the present embodiment is at a position 5 cm lower than the inferior end of the patella (the semi-long-tights-type garments of the embodiments described below have the same hem line positions, unless otherwise specified).  
      The semi-long-tights-type leg support garment shown in FIGS.  89  to  92  is, according to the foregoing preferred embodiment of the present invention, arranged so that the stretchable portion (A 2   1 )  121   a  having a relatively great straining force covers a portion  4  of a part of an inferior region of the patella  1  so as to support the patella  1  as if pulling up the same from the inferior side, thereby improving the stability of the knee joint. The portion  121   a  further supports the musculus sartorius  6  and extends from the medial side to the lateral side of the thigh obliquely and spirally toward the vicinity of the trochanter major  8 , thereby increasing the power for pulling the stretchable portion having a relatively great straining force that supports the ligamentum collateralle medialis  3 . This makes it possible to provide a leg support garment having an increased power for supporting the ligamentum collateralle medialis  3 , and hence, this is preferable. Furthermore, this provides the support to the musculus sartorius  6  that complements the function of the ligamentum collateralle medialis  3  as well, which is also preferable. Furthermore, the portion  121   a  includes the stretchable portion (A 2   1 - 1 )  122  having a relatively great straining force, which extends upward further from the vicinity of the trochanter major  8  to the waist  10  along the tractus iliotibialis  9 . Therefore, the function of intensely pressing the trochanter major  8  is enhanced, thereby improving the connection between the caput ossis femoris and the acetabulum. This is preferable since further providing a function of enhancing the stability of the hip joint.  
      Next, FIGS.  93  to  96  are views illustrating another embodiment of a semi-long-tights-type leg support garment of the present invention.  FIG. 93  is a rear view of the same,  FIG. 94  is a front view of the same,  FIG. 95  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 94 , and  FIG. 96  is a right-side view of the same.  
      The garment of the present embodiment is a garment as a modification of the embodiment shown in FIGS.  89  to  92 ; namely, to the garment shown in FIGS.  89  to  92 , a stretchable portion (B 2 )  124   a  having a relatively great straining force as described below is added. Namely, the garment further includes a stretchable portion (B 2 )  124   a  having a relatively great straining force. The stretchable portion (B 2 )  124   a  having a relatively great straining force extends from a vicinity of the trochanter major  8  downward approximately along the tractus iliotibialis  9  to the lateral side of the patella  1 , covers a part of an inferior region  14  of the patella extending from the lateral side thereof.  
      The upper portion (A 2   1 - 1 )  122   a  having a relatively greater straining force has a slightly greater width as compared with that shown in FIGS.  89  to  92 , at a position where the stretchable portion (B 2 )  124   a  having a relatively great straining force and the stretchable portion (A 2   1 )  121   a  having a relatively great straining force are united therewith.  
      With the foregoing preferred embodiment of the present invention, the same function as that explained with reference to FIGS.  89  to  92  is exhibited. Besides, since the stretchable portion (B 2 )  124   a  having a relatively great straining force is further provided, the knee is supported from the both sides. Thus, the function of supporting the knee joint is reinforced. Furthermore, the function of pressing the trochanter major  8  is enhanced further, thereby improving the connection between the caput ossis femoris and the acetabulum. Therefore, this reinforces a function of enhancing the stability of the hip joint.  
      Next, FIGS.  97  to  100  are views illustrating still another embodiment of a semi-long-tights-type leg support garment of the present invention.  FIG. 97  is a rear view of the same,  FIG. 98  is a front view of the same,  FIG. 99  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 98 , and  FIG. 100  is a right-side view of the same.  
      The garment of the present embodiment is equivalent to a semi-long-tights-type leg support garment obtained by, from the long-tights-type leg support garment shown in FIGS.  21  to  24 , cutting away a part lower than a position of the portion  4  of the stretchable portion  121  having a relatively great straining force that covers the inferior region of the patella  1 .  
      The portion expressed as the stretchable portion (A) having a relatively great straining force is composed of a stretchable portion (A 2   2 )  130   a  having a relatively great straining force. The stretchable portion (A 2   2 )  130   a  having a relatively great straining force substantially covers the ligamentum collateralle  3  on the medial side of the knee joint of the human body, and extends approximately along a vicinity of a periphery of the patella  1  on the medial side thereof so as to surround the patella  1  through not less than approximately ¼ of the periphery of the patella  1  and to cover a part of an inferior region  4  of the patella  1 , and then, reaches a side of a superior part of the musculus gastrocnemius on the medial side. Furthermore, on the superior side of the knee joint, the stretchable portion (A 2   2 )  130   a  extends through the thigh approximately along the musculus semitendinosus  21  to the vicinity of the sulcus gluteus  22 .  
      The foregoing preferred embodiment allows the stretchable portion  130   a  having a relatively great straining force to cover a part of the inferior region  4  of the patella  1 , thereby support the patella  1  as if pulling up the patella  1  from the inferior side thereof. As a result, the stability of the knee joint is improved. Furthermore, the embodiment allows the portion  130   a  to support the musculus semitendinosus  21  that is located on the medial side of the thigh, thereby increasing the power of pulling the stretchable portion having a relatively great straining force that supports the ligamentum collateralle medialis  3 . Consequently, a leg support garment with an increased power for supporting the ligamentum collateralle medialis  3  is provided, which is preferable. Furthermore, the musculus semitendinosus that complements the function of the ligamentum collateralle medialis is supported, which is also preferable.  
      Next, FIGS.  101  to  104  are views illustrating still another embodiment of a semi-long-tights-type leg support garment of the present invention.  FIG. 101  is a rear view of the same,  FIG. 102  is a front view of the same,  FIG. 103  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 102 , and  FIG. 104  is a right-side view of the same.  
      The garment of the present embodiment is equivalent to a semi-long-tights-type leg support garment obtained by, from the long-tights-type leg support garment shown in FIGS.  25  to  28 , cutting away a part lower than a position of the portion  4  of the stretchable portion  131  having a relatively great straining force that covers the inferior region of the patella  1 .  
      The portion expressed as the stretchable portion (A) having a relatively great straining force is composed of a stretchable portion  131   a  having a relatively great straining force. The stretchable portion  131   a  having a relatively great straining force substantially covers the ligamentum collateralle  3  on the medial side of the knee joint of the human body, and extends approximately along a vicinity of a periphery of the patella  1  on the medial side thereof so as to surround the patella  1  through not less than approximately ¼ of the periphery of the patella  1  and to cover a part of an inferior region  4  of the patella  1 , and then, reaches a side of a superior part of the musculus gastrocnemius on the medial side. Furthermore, on the superior side of the knee joint, the portion  131   a  passes through the thigh approximately along the musculus gracilis  23 , and reaches the vicinity of the crotch  24 .  
      The foregoing preferred embodiment allows the stretchable portion  131   a  having a relatively great straining force to cover a part of the inferior region  4  of the patella  1 , thereby support the patella  1  as if pulling up the patella  1  from the inferior side thereof. As a result, the stability of the knee joint is improved. Furthermore, the embodiment allows the portion  131   a  to support the musculus gracilis  23  that is located on the medial side of the thigh, thereby increasing the power of pulling the stretchable portion having a relatively great straining force that supports the ligamentum collateralle medialis  3 . Consequently, a leg support garment with an increased power for supporting the ligamentum collateralle medialis  3  is provided, which is preferable. Furthermore, the musculus gracilis that complements the function of the ligamentum collateralle medialis is supported, which is preferable.  
      Next, FIGS.  105  to  108  are views illustrating still another embodiment of a semi-long-tights-type leg support garment of the present invention.  FIG. 105  is a rear view of the same,  FIG. 106  is a front view of the same,  FIG. 107  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 106 , and  FIG. 108  is a right-side view of the same.  
      The garment of the present embodiment is equivalent to a semi-long-tights-type leg support garment obtained by, from the long-tights-type leg support garment shown in FIGS.  45  to  48 , cutting away a part lower than a position of the portion  32  that covers a part of the lateral inferior region of the patella  1 .  
      The garment of the present embodiment is a leg support garment in which the portion expressed as the stretchable portion (A) having a relatively great straining force is a stretchable portion (A 2   2 ′)  142   a  having a relatively great straining force, and the stretchable part having a relatively great straining force further includes a stretchable portion (B 2 ′)  143   a  having a relatively great straining force. The stretchable portion (A 2   2 ′)  142   a  having a relatively great straining force substantially covers the ligamentum collateralle  3  on the medial side of the knee joint of the human body, extends approximately along the vicinity of a periphery of the patella  1  on the medial side thereof so as to surround the patella  1  through at least more than approximately ½ of the periphery of the patella  1  and to cover a part of inferior and superior regions  4  and  11  of the patella  1 , and reaches a side of a superior part of the musculus gastrocnemius on the medial side. Further, on the superior side of the knee joint, in the femoral region, the stretchable portion (A 2   2 ′)  142   a  having a relatively great straining force extends approximately along the musculus semitendinosus and the musculus gracilis, and reaches the vicinity below the crotch  24  and a vicinity of the sulcus gluteus  22 . The stretchable portion (B 2 ′)  143   a  having a relatively great straining force extends from a side part of the waist  10  approximately along the tractus iliotibialis  9  via a vicinity of the trochanter major  8 , then, approximately along the tractus iliotibialis  9  to the lateral side of the patella  1 , surrounds the patella  1  through approximately ½ or more of the periphery of the patella  1  so as to cover a part of an inferior region  32  and a superior region  33  of the patella  1 , and reaches a side of a superior part of the musculus gastrocnemius on the lateral side.  
      In the foregoing embodiment, two portions  4  and  11  of the stretchable portion (A 2   2 ′)  142   a  having relatively great straining forces project toward the medial side therefrom and cover a part of the inferior region  4  and a part of the superior region  11  of the patella  1 , respectively. Besides, two portions  32  and  33  of the stretchable portion (B 2 ′)  143   a  having relatively great straining forces project toward the lateral side therefrom and cover a part of the inferior region  32  and a part of the superior region  33  of the patella  1 , respectively. Here, the two portions  4  and  11  of the stretchable portion (A 2   2 ′)  142   a  having a relatively great straining force are arranged opposite to the two portions  32  and  33  of the stretchable portion (B 2 ′)  143   a  having a relatively great straining force, respectively, and at positions slightly shifted to the inferior side from positions of the portions  32  and  33  of the stretchable portion (B 2 ′)  143   a  having a relatively great straining force, respectively. Furthermore, when viewed from the front, the portion covering the inferior region  4  of the patella  1 , of the stretchable portion (A 2   2 ′)  142   a  having a relatively great straining force, has a relatively greater area.  
      The foregoing preferred embodiment allows the stretchable portions having relatively great straining forces to support the knee and leg from both sides in the femoral region and the lower leg region, without hindering the action of the musculus vastus lateralis and the musculus vastus medialis on the anterior side of the thigh, and further, allows the knee joint to be supported as if wrapped from the surrounding, thereby providing further support of the knee joint. Besides, the function of pressing the trochanter major  8  is reinforced, thereby further improving the connection between the caput ossis femoris and the acetabulum. Therefore, the function of enhancing the stability of the hip joint is reinforced, which is preferable.  
      Furthermore, in the lower leg region, on the medial side, the muscles are fewer and the tibia is in contact with the surface of the body. On the other hand, on the lateral side of the lower leg region, the musculus gastrocnemius is on the lateral side of the fibula. Therefore, the foregoing embodiment provides the support of the knee joint as if pulling the medial side thereof having fewer muscles more intensely from the inferior side, thereby reinforcing the support of the ligamentum collateralle medialis, which is preferable.  
      As described above, in the foregoing embodiment, as to the two portions  4  and  11  of the stretchable portion (A 2   2 ′)  142   a  having a relatively great straining force that project to the lateral side and cover a part of the inferior region  4  and a part of the superior region  11  of the patella  1 , respectively, and the two portions  32  and  33  of the stretchable portion (B 2 ′)  143   a  having a relatively great straining force that project to the medial side and cover a part of the inferior region  32  and a part of the superior region  33  of the patella  1 , respectively, the position of the projecting portion  4  is slightly inferior to the position of the projecting portion  32 , and the position of the projecting portion  11  is slightly inferior to the position of the projecting portion  32 . Therefore, this provides the support of the knee joint as if pulling the medial side thereof having fewer muscles more intensely from the inferior side, thereby reinforcing the support of the ligamentum collateralle medialis, which is preferable. However, the projecting portion  4  may be at a position as high as the position of the projecting portion  32 , or the projecting portion  11  may be at a position as high as a position of the projecting portion  33 . Besides, the two portions  4  and  11  projecting toward the lateral side may further extend over the central line of the anterior side of the leg toward the lateral side, while the portions  32  and  33  opposite thereto may further extend over the central line of the anterior side of the leg toward the medial side. Alternatively, the projecting portions  4  and  32  may be connected with each other, and likewise, the projecting portions  11  and  33  may be connected with each other. Furthermore, the projecting portion  4  may be located at a position shifted slightly to the superior side of the projecting portion  32 , while the projecting portion  11  may be located at a position shifted slightly to the superior side of the projecting portion  33 .  
      Next, FIGS.  109  to  112  are views illustrating still another embodiment of a semi-long-tights-type leg support garment of the present invention.  FIG. 109  is a rear view of the same,  FIG. 110  is a front view of the same,  FIG. 111  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 110 , and  FIG. 112  is a right-side view of the same.  
      The garment of the present embodiment is a garment as a modification of the embodiment shown in FIGS.  85  to  88 ; namely, in the garment of the embodiment shown in FIGS.  85  to  88 , the stretchable portion (A 2   1 )  121   a  having a relatively great straining force and the stretchable portion (B 2 )  124   a  having a relatively great straining force are brought in contact with each other at a position on the inferior side of the patella Therefore, the same portions as those of the embodiment shown in FIGS.  85  to  88  are designated with the same reference numerals in the drawings and descriptions of the same are omitted.  
      More specifically, a projecting portion  4  of the stretchable portion  121   a  having a relatively great straining force that covers a part of the inferior region of the patella  1  and a projecting portion  14  of the stretchable portion  124   a  having a relatively great straining force that covers a part of the inferior region of the patella  1  are coupled with each other at a position on the inferior side of the patella  1 , so as to support the knee from the right, left, and inferior sides of the same. Therefore, the same function as that of the leg support garment shown in FIGS.  85  to  88  is displayed. Besides, since the portions denoted with  4  and  14  are brought into contact with each other, the hems of the garment are stably positioned on the inferior sides of the knees, and the loosening of the garment, such as the sliding up, hardly takes place.  
      Next, FIGS.  113  to  116  are views illustrating still another embodiment of a semi-long-tights-type leg support garment of the present invention.  FIG. 113  is a rear view of the same,  FIG. 114  is a front view of the same,  FIG. 115  is a cross-sectional view of the same taken along an A-A′ line in  FIG. 114 , and  FIG. 116  is a right-side view of the same.  
      The garment of the present embodiment is a garment as a modification of the embodiment shown in FIGS.  109  to  112 ; namely, in the garment of the embodiment shown in FIGS.  109  to  112 , the stretchable portion (A 2   1 )  121   a  having a relatively great straining force and the stretchable portion (B 2 )  124   a  having a relatively great straining force are coupled with each other in a slightly wide range on the inferior side of the patella, rather than in point contact with each other. Therefore, the same portions as those of the embodiment shown in FIGS.  109  to  112  are designated with the same reference numerals in the drawings and descriptions of the same are omitted.  
      More specifically, a projecting portion  4  of the stretchable portion  121   a  having a relatively great straining force that covers a part of the inferior region of the patella  1  and a projecting portion  14  of the stretchable portion  124   a  having a relatively great straining force that covers a part of the inferior region of the patella  1  are coupled with each other at a position on the inferior side of the patella  1 , so as to support the knee from the right, left, and inferior sides of the same. Therefore, the same function as that of the leg support garment shown in FIGS.  109  to  112  is displayed, and the function of supporting the knee from the inferior side is further reinforced.  
      It should be noted that in the case of the present embodiment, in the case where the stretchable part having a relatively great straining force is formed by laminating stretchable fabrics in predetermined shapes on a garment main body and sewing them, or the like, the coupling between the portion  4  of the stretchable portion  121   a  having a relatively great straining force that covers a part of the inferior region of the patella  1  and the portion  14  of the stretchable portion  124   a  having a relatively great straining force that covers a part of the inferior region of the patella  1  may be achieved by forming the same with one piece of fabric in which the stretchable portions  121   a  and  124   a  having relatively great straining forces are continuously provided, so that the coupling therebetween has been achieved beforehand. Alternatively, the stretchable portions  121   a  and  124   a  having relatively great straining forces may be made of separate pieces of fabrics, respectively, and portions of the fabrics corresponding to the portions  4  and  14  may be overlapped and sewn so that the coupling therebetween is achieved.  
      So far, several embodiments of semi-long-tights-type leg support garments have been described with reference to the drawings. The present invention, however, is not limited to these, and the various kinds of long-tights-type leg support garments described above with reference to the drawings may be applied as semi-long-tights-type garments by cutting away the portions lower than the knee.  
      Furthermore, any design of a garment in which an upper body part is added to the semi-long-tights-type leg support garment of the present invention as required is not excluded from the present invention at all, as long as the object of the present invention is not inhibited. As to the ankle-length leg support garment of the present invention, any garment of this type to which a piece of fabric traversing the sole is attached so as to connect both sides of the hem of each leg part is not excluded from the present invention at all.  
      Meanwhile, in the long-tights-type and semi-long-tights-type leg support garments, any seam line of the main body of the garment preferably does not run through at least a region covering the ligamentum collateralle in the stretchable portion having a relatively great straining force located over the ligamentum collateralle on the medial side of the knee joint.  
      More specifically, as to the leg support garment of the present invention of any type, the long-tights-type or the semi-long-tights-type, it is necessary to form a portion covering the leg part into a cylindrical form, and applicable as a method for forming the leg part into a cylindrical form is, for instance, a method for rolling a flat fabric into a cylindrical form and seaming a hem on one side of the fabric and a hem on the other side of the fabric together. In the case where a fabric is thus shaped in a cylindrical form by seaming the same, conventionally it is usual that the sawing is carried out so that the seam line passes the medial side of the leg part.  
      In the present invention, it is preferable to design the garment so that the seam line of the main body of the garment does not run through at least a region thereof covering the ligamentum collateralle in the stretchable portion having a relatively great straining force located on the ligamentum collateralle on the medial side of the knee joint. To facilitate the understanding, the seam line of the main body of the garment whose leg part is formed in a cylindrical form is described below, taking concrete examples with reference to a few of the drawings.  
       FIG. 117  is a drawing in which a seam line of the main body of the garment whose leg part is formed in a cylindrical form is drawn into  FIG. 7 . More specifically,  FIG. 117  illustrates an embodiment in the case where a seam line  50  of the main body of the garment whose leg part is formed in a cylindrical form runs on a medial side of the leg part. The garment is designed so that the seam line  50  of the main body of the garment whose leg part is formed in a cylindrical form passes on a hem of a part of the stretchable portion  121  having a relatively great straining force located over the ligamentum collateralle  3  on the medial side of the knee joint, avoiding at least a region thereof immediately above the ligamentum collateralle  3 . Thus, the description “does not run through at least a region covering the ligamentum collateralle in the stretchable portion having a relatively great straining force located on the ligamentum collateralle on the medial side of the knee joint” is used so as to mean that the seam line is allowed to run on the hem of the region covering the ligamentum collateralle of the stretchable portion having a relatively great straining force. Of course, the garment may be designed so that the seam line passes through positions slightly distanced from the region covering the ligamentum collateralle of the stretchable portion having a relatively great straining force, without running on the hem of the region of the ligamentum collateralle at all.  
      Next,  FIG. 118  is a view illustrating another embodiment different from that shown in  FIG. 117 , for explaining a position of the seam line of the main body of the garment.  FIG. 118  is a drawing in which the seam line of the main body of the garment whose leg part is formed in a cylindrical form is drawn into  FIG. 8 . More specifically,  FIG. 118  illustrates an embodiment in the case where a seam line  51  of the main body of the garment whose leg part is formed in a cylindrical form runs on a lateral side of the leg part. In the case where the seam line of the main body of the garment whose leg part is formed in a cylindrical form runs on a lateral side of the leg part, the seam line by no means runs through at least a region covering the ligamentum collateralle in the stretchable portion having a relatively great straining force located on the ligamentum collateralle on the medial side of the knee joint. Therefore, such a seam line basically may be allowed to run through any position as long as the position is on the lateral side of the leg part. However, in the case where a certain stretchable portion having a relatively great straining force exists on the lateral side of the leg part, it is preferable to design the garment so that, if possible, the seam line should, for instance, pass along the hem of the same, avoiding the stretchable portion having a relatively great straining force, or that the seam line should be located at a position slightly distanced from the region covering the ligamentum collateralle of the stretchable portion having a relatively great straining force. In the example shown in  FIG. 118 , the seam line  51  of the main body of the garment whose leg part is formed in a cylindrical form is provided along the hem on one side of the stretchable portion  121  having a relatively great straining force in an upper part of the garment, and then, passes through approximately the center of the side part of the garment, slightly away from the stretchable portion  121  having a relatively great straining force, in a lower part from a position at a distance of approximately ⅓ of the total length of the garment from the waistline  10 .  
      Next,  FIG. 119  is a view illustrating still another embodiment different from that shown in  FIGS. 117 and 118 , for explaining a position of the seam line of the main body of the garment.  FIG. 119  is a drawing in which the seam line of the main body of the garment whose leg part is formed in a cylindrical form is drawn in  FIG. 80 . More specifically,  FIG. 118  illustrates another embodiment in the case where a seam line  52  of the main body of the garment whose leg part is formed in a cylindrical form runs on a lateral side of the leg part. In the example shown in  FIG. 118 , the seam line  52  of the main body of the garment whose leg part is formed in a cylindrical form is provided along a hem on the posterior side of the stretchable portion  156  having a relatively great straining force. By sewing the garment through the foregoing line, the seam line runs on the hem of the stretchable portion  156  having a relatively great straining force. Therefore, the seam line by no means independently appears on the garment, thereby hardly harming the appearance of the garment. Consequently, an advantage in that the design of the garment is not impaired is achieved. Particularly in the case where the stretchable portion having a relatively great straining force is composed of a patch of a fabric, the sewn portions constitute sewn portions where the patch of the fabric and the main body of the garment are sewn together. Therefore, the design of the garment is not impaired. Furthermore, since the sewn portions are such commonly sewn portions, the leg support garment of the present invention can be formed with fewer sewn portions. The foregoing is a mere example, but in the case where the stretchable portion having a relatively great straining force extends on the lateral side of the leg part of the garment, approximately from the upper end to the lower end of the garment, it is preferable that the seam line of the main body of the garment whose leg part is formed in a cylindrical form is provided along the hem of the stretchable portion having a relatively great straining force, since the aforementioned advantages and the like can be achieved.  
      The foregoing description explains the seam line of the main body of the garment in the case where the leg part thereof is formed in a cylindrical form, while referring to a few concrete examples, but the present invention is not limited to the concrete examples shown in the drawings.  
      As described above, with the preferred embodiment of the present invention, in which the seam line of the main body of the garment does not run through at least a region covering the ligamentum collateralle in the stretchable portion having a relatively great straining force located over the ligamentum collateralle on the medial side of the knee joint, the insufficiency of the power for supporting the ligamentum collateralle medialis can be avoided; the insufficiency of the power is caused in the case where a seam line runs through at least a region covering the ligamentum collateralle medialis in the stretchable portion having a relatively great straining force located over the ligamentum collateralle medialis, since the stretchability is decreased by the seam line. Therefore, with the preferred embodiment of the present invention, the straining force of the stretchable portion having a great straining force located over the ligamentum collateralle medialis is displayed sufficiently, which is preferable.  
      In a garment of the present invention, a stretchable portion having a relatively great straining force may be formed by laminating a stretchable fabric having a predetermined shape on the main body of the garment and sewing it, or by laminating a stretchable fabric having a predetermined shape on the main body of the garment and bonding it. Particularly, according to the former method, a garment having durability can be produced easily. Of course, a leg support garment of the present invention may be formed by preparing stretchable portions having relatively great straining forces and other portions as respective parts of predetermined shapes and seaming them together. However, such sewing is complex and takes a lot of labor.  
      Furthermore, for example, a stretchable portion having a relatively great straining force may be formed by stretching and laminating a stretchable fabric having a predetermined shape on the main body of the garment and sewing or bonding it. These methods are favorable when applying a stronger straining force by the stretchable portion having a relatively great straining force.  
      Furthermore, a stretchable portion having a relatively great straining force may be formed by impregnating or coating a predetermined part of the main body fabric of the garment with a solution or emulsion of a synthetic resin or rubber having elasticity followed by drying, or by laminating a film of a synthetic resin or rubber having elasticity on a predetermined part of the main body fabric of the garment. According to these methods, a stretchable portion having a relatively great straining force can be obtained with a relatively small thickness. As the synthetic resin having elasticity, suitable elastic resins such as polyurethane resins, polyester elastomer resins, etc. may be used.  
      Furthermore, a stretchable portion having a relatively great straining force may be formed by changing the knitting stitch of a stretchable fabric that forms the main body of the garment to a stitch with a greater straining force. According to this method, because lamination also is not necessary, a stretchable portion having a relatively great straining force can be formed thinner. The definition of the method in which a stretchable portion having a relatively great straining force is formed by changing the knitting stitch as described also includes a method of forming a stretchable portion having a relatively great straining force by using, among the fiber materials forming the main body of the garment, an elastic fiber thicker than those used in other portions, and a method of forming the same by increasing the density of the elastic fiber as compared with the other portions. According to any one of these methods, because lamination also is not necessary, a stretchable portion having a relatively great straining force can be formed further thinner.  
      Furthermore, in the case where the circular-knitting fabric is used as the fabric that forms the garment, it is possible to form the stretchable portions having great straining forces by the cut-boss knitting method.  
      Among the above-described methods for forming a stretchable portion having a relatively great straining force, preferred are the method of laminating a stretchable fabric having a predetermined shape on the main body of the garment and sewing it, and the method of stretching and laminating a stretchable fabric having a predetermined shape on the main body of the garment and sewing it. According to these methods, the straining force of the stretchable fabric sewn to the main body of the garment may be slightly smaller than, the same as, or larger than the straining force of the stretchable fabric of the main body of the garment. This is because lamination of a stretchable fabric on the main body of the garment results in increased straining force in the laminated part. The degree of the straining force of the fabric to be laminated may be chosen as appropriate depending on the type of the garment, intended use, preference of the wearer, etc.  
      Meanwhile, to facilitate the understanding, the technique for forming the stretchable portion having a relatively great straining force by the aforementioned cut-boss knitting method will be described below, with reference to FIGS.  120  to  122 .  
      FIGS.  120  to  122  are cross-sectional conceptual process views illustrating the cut-boss knitting technique in the circular knitting. A side indicated by a dotted arrow A is a front side of the circular knitting fabric, and a side indicated by a dotted arrow B is a back side of the circular knitted fabric.  
      First of all, as shown in  FIG. 120 , when a front yarn  61  and a back yarn  62  are supplied to a circular knitting machine for knitting, an intermediate yarn  63  is inserted between the front yarn  61  and the back yarn  62  so that the front, intermediate, and back yarns  61 ,  63 , and  62  are supplied together to the circular knitting machine so as to be knitted in a portion that is to have a relatively greater straining force by means of the cut-boss technique. These portions are portions between arrows  64   a  and  64   b  and between arrows  64   c  and  64   d  (it should be noted that the intermediate yarn  63  is indicated with an alternate long and short dash line for conveniences sake.) In a portion to be formed as the portion having a relatively small straining force, like the portion between the arrows  64   b  and  64   c , the intermediate yarn  63  is not inserted between the front and back yarns  61  and  62  thereby floated on the back side, so that the portion is knitted with only the front and back yarns  61  and  62 . Subsequently, the intermediate yarn  63  thus floated is cut at the positions indicated by the arrows  64   a ,  64   b ,  64   c , and  64   d . Consequently, as shown in  FIG. 121 , portions z 1  and z 3  compose stretchable portions having relatively great straining forces in which the intermediate yarn  63  is inserted, while a portion z 2  composes a stretchable portion having a relatively small straining force that is knitted with only the front and back yarns  1  and  2 .  
       FIG. 122  is a cross-sectional conceptual view illustrating a circular knitting fabric obtained by the cut-boss knitting technique.  61   a  is a front surface part of the circular knitting fabric on which the front yarn  61  appears,  62   a  is a back surface part of the circular knitting fabric on which the back yarn  62  appears,  63   a  is a reinforcing layer composed of the intermediate yarn  63 , portions z 1  and z 3  are stretchable portions having relatively great straining forces, and z 2  is a stretchable portion having a relatively small straining force.  
      In the present invention, the stretchable portion having a relatively great straining force and the stretchable portion having a relatively small straining force may be formed by only the cut-boss knitting technique as described above, or alternatively, in addition to the foregoing technique, a technique of varying the straining force by the stitch adjustment in each course of the circular knitting fabric may be used in combination.  
      Although not particularly limited, it is preferable that a stretchable portion having a relatively great straining force has a straining force of 0.3 N to 4 N approximately in its length direction. Within this range of straining force, the functions of the present invention are exhibited effectively, and moreover compressive feeling is not too strong, and wearing comfort is excellent. Even if the straining force of a stretchable portion having a relatively smaller straining force exceeds 0.3 N, it is justified as long as the straining force is smaller than those of any of the strong straining portions formed in the garment.  
      In the case where straining forces of fabrics used as a stretchable portion having a relatively great straining force and a stretchable portion having a relatively small straining force are measured, the following tensile test is carried out.  
      A 2.5 cm×16.0 cm (width×length) sample is formed so that the fabric warp direction (wale direction) is the lengthwise direction of the sample. The sample is placed so that the lengthwise direction is directed in the vertical direction, and both ends of the sample are gripped with clips. The sample is placed to the constant-speed extension-type tensile tester (“AUTOGRPH AG-500D” manufactured by Shimazu Corporation), with an upper grip length and a lower grip length being set to be 2.5 cm and 3.5 cm, respectively, and hence, a space between grips set to be 10.0 cm. The sample is stretched at a rate of 30±2 cm/min, up to a stretching degree of 80%. Here, a stress applied to the sample when the stretching degree is 30% is recorded as a stretching force (unit: N) [1 gf≈0.0098 N]. Then, the stress applied to the sample stretched to the stretching degree of 80% is removed, and the sample contracts toward its original length. Here, a stress applied to the sample when the stretching degree is recovered to approximately 30% is measured as a straining force (unit: N). The foregoing tensile tester is set so that these values are recorded automatically. It should be noted that each of the stretching force and the straining force was determined by measuring two samples and averaging the obtained values.  
      Here, the stretching degree (%) is a value expressed as [(d−e)/e]×100 where d represents a length in a stretching direction of a fabric in a stretched state, and e represents an original length of the sample before stretched (i.e., a space between grips).  
      It should be noted that the sample to be used for the measurement of the stretchability and the straining force preferably has the size as described above, but if a sample of this size cannot be cut out from the garment to be measured, a smaller sample may be used. However, because measurement error increases as the size of the sample decreases, it is preferable that a sample as large as possible is cut out and measured.  
      The width of a stretchable portion having a relatively great straining force in a garment of the present invention is not particularly limited, and it may be chosen as appropriate depending on the part where the stretchable portion having a relatively great straining force is present, the strength of the straining force of the material used, the means for forming the stretchable portion having a relatively great straining force, the purpose of use of the garment (for instance, the degree of disorder of the knee of the wearer, the part that suffers from the disorder, the aim of preventing disorder, and the type of the sports played), whether the wearer is an adult or a child, etc. to the extent so that the object of the present invention is achieved. Besides, the width necessarily varies with the part where it is applied. Therefore, it is difficult to specify the width numerically in general, but if the portion has a very small width, almost in a line form, it is useless, and the portion preferably has an average width of not less than 2 cm, and more preferably not less than 3 cm. Normally, the portion preferably has a width of not more than 15 cm where the portion is widest, and more preferably not more than 13 cm.  
      Of course, the width of a stretchable portion having a relatively great straining force may be partially smaller or greater depending on the part to the extent so that the object of the present invention is achieved.  
      In the present invention, the various stretchable portion having relatively great straining forces for supporting the muscles are mainly provided in directions approximately along the directions of fibers of the muscles and ligaments except for specific details. By so doing, the contraction of the muscles and the functions of the ligaments are supported without impairing the function of the muscles and ligaments.  
      Furthermore, a garment of the present invention may preferably use, as a stretchable fabric, a polyurethane fiber-containing power net that is a polyurethane fiber-containing stretch raschel knitted fabric, a polyurethane fiber-containing two-way stretch tricot knitted fabric that is a polyurethane fiber-containing tricot knitted fabric, a polyurethane fiber-containing circular knitting fabric, etc. Therefore, compared with a conventional supporter using a relatively thick pile fabric or neoprene sheet, etc., a fabric having a thickness in a range as used when making a usual garment, e.g. from about 0.3 mm to about 0.8 mm, may be used. Thus, a garment can be provided that reduces the wearer&#39;s appearance little such as the figure when worn, fits well to the body, and has relatively good ventilation. The kind of the power net includes, for example, a plane power net, satin power net, two-way stretch raschel, “TRISKIN” (trademark of Urabe Corporation), etc.  
      It is not necessary that all stretchable portions having relatively great straining forces have the same straining force, and they may have different straining forces depending on the part.  
      The kind of fiber yarns forming the fabric of the garment is not particularly limited, and various fiber yarns may be used, such as various synthetic fiber yarns made of polyester, nylon, etc., natural fiber yarns made of cotton, wool, silk, etc., semisynthetic fiber yarns made of rayon, etc., elastic fiber yarns made of polyurethane, etc., mixed fiber yarns made of mixtures of at least two kinds of these, a covering yarn, a water-absorptive quick-dry yarn, and other processed yarns.  
      In the case where an elastic yarn is used, a yarn made of elastic fibers alone may be used. However, it is more preferable to use an elastic fiber yarn that is covered with another fiber such as the aforementioned water-absorptive quick-dry yarn, a synthetic fiber yarn with an excellent water-repellency, or a natural fiber yarn, etc., depending on the purpose.

      By so doing, the stretchable portion (C) having a relatively great straining force is provided, which provides the firm support of the musculus gluteus maximus in the muscular fiber direction thereof. Thus, it can play a large role in supporting the rotating motion of the hips, preventing a decrease in the rotating angle of the hips, and stabilizing the pelvis in anterior-posterior direction. For an elderly person, it is effective in preventing falling down. Furthermore, it can play a large role in extending the hip joint in anterior-posterior direction when running, jumping, and climbing up a slope. Besides, the stretchable portion (D) having a relatively great straining force is provided, which supports a part of the musculus rectus abdominis and the musculus obliquus internus abdominis, thereby providing functions of reducing lumbar lordosis, maintaining good posture, making youthful figure, and preventing generation of pains such as lumbar pains.

By so doing, the leg support garment has a length capable of covering at least a range from the waistline to the inferior side of the knee. Therefore, the power of pulling the stretchable portion having a relatively great straining force that supports the ligamentum collateralle medialis, described in the above item (1), is exerted more intensely where the portion extends upward to the superior part of the thigh. Consequently, this provides a leg support garment in which the power of supporting the ligamentum collateralle medialis is improved, which is preferable. Moreover, since it is a tights-type garment, it is easy to wear, and suitable as sports wear. Particularly, it is suitably worn in high temperature areas or in the hot season.  
      (19) Furthermore, the leg support garment according to the above item (18) is arranged according to a preferred embodiment of the present invention wherein:  
      the portion expressed as the stretchable portion (A) having a relatively great straining force is a stretchable portion (A 2   1 ) having a relatively great straining force that: 
          substantially covers the ligamentum collateralle on the medial side of the knee joint of the human body;     extends approximately along a vicinity of a periphery of the patella on a medial side thereof so as to surround the patella through not less than approximately ¼ of the periphery of the patella and to cover at least a part of an inferior region of the patella, and reaches a side of a superior part of the musculus gastrocnemius on the medial side; and     on a superior side of the knee joint, extends from a medial side to a lateral side of the thigh via an anterior side thereof approximately along the musculus sartorius to a vicinity of the trochanter major, passing a superior part of the musculus rectus femoris. 
 
 By so doing, the stretchable portion having a relatively great straining force covers a portion of an inferior region of the patella so as to support the patella as if pulling up the same from the inferior side, thereby improving the stability of the knee joint. The portion further supports the musculus sartorius and extends from the medial side to the lateral side of the thigh obliquely and spirally toward the vicinity of the trochanter major, thereby increasing the power for pulling the stretchable portion having a relatively great straining force that supports the ligamentum collateralle medialis.
