Title: Sports glove

Description:
This nonprovisional application is based on Japanese Patent Application No. 2008-91671 filed on Mar. 31, 2008 and No. 2009-080101 filed on Mar. 27, 2009 with the Japan Patent Office, the entire contents of which are hereby incorporated by reference. 
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a sports glove, more specifically to a sports glove made of hardly-slippery natural leather providing a good fit. 
     2. Description of the Background Art 
     Conventionally, a glove stitched such that a leather grain side is left to be located on a surface of the glove is known as the sports glove made of the natural leather, and various proposals have been made to improve the hard-slipperiness and the good fit. For example, in a sports glove disclosed in Japanese Patent Laying-Open No. 2001-299982, a grain side is disposed on a backside of the glove, whereby the glove is hardly slippery even when the glove gets wet and a good fit is given to a hand. 
     In the sports glove disclosed in Japanese Patent Laying-Open No. 2001-299982, although the grain side is applied to a surface in contact with the hand so as to improve the hard-slipperiness between the hand and the glove, there is a demand for further improvements of the hard-slipperiness and the good fit. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing problems, it is an object of the present invention to provide a sports glove that can further improve the hard-slipperiness and the good fit in comparison to conventional gloves. 
     According to an aspect of the present invention, there is provided a sports glove having a leather member disposed on a palmar side, the leather member being made of natural leather and having a front side and a backside each applied with a grain side. 
     Accordingly, the grain side can be applied to the surface in contact with the hand on the palmar side of the glove, and the grain side can also be applied to the surface of the glove in contact with the member such as a bat. As a result, the slipperiness can be suppressed between the hand and the glove as well as between the glove and the member such as the bat, and the good fit can be provided because the grain side constitutes the surface in contact with the hand. 
     The sports glove according to the aspect of the present invention may include a palmar portion that covers a palm; and a finger portion that covers fingers, wherein the leather member is disposed on at least part of a palmar side of the finger portion and in at least part of the palmar portion. In such cases, the leather member can be disposed on regions of the palmar portion and finger portion, which influence the hard-slipperiness, because a player lays stress on the regions when grasping the bat. 
     The sports glove according to the aspect of the present invention may include a palmar portion that covers a palm, wherein the leather member is disposed on at least part of the palmar portion. In such cases, the leather member can be disposed on regions of the palmar portion and finger portion, which influence the hard-slipperiness, because the player lays stress on the regions when grasping the bat. 
     In the sports glove according to the aspect of the present invention, a stitch may be formed on the leather member. In such cases, the leather member in which the grain sides are applied to both the surfaces (that is, the member in which the two pieces of natural leather are overlapped with the grain side orientated toward an outer circumference) is fixed to the stitched portion. Therefore, a possibility of generating the slipperiness between the glove and the hand or between the glove and the member such as the bat can be reduced. The generation of the slipperiness is caused by a deviation between the two pieces of natural leather of the leather member. 
     In the sports glove according to the aspect of the present invention, the stitch may be formed so as to be gradually brought closer to a wrist from a thumb toward a little finger in the leather member. In such cases, when the player swings the bat while grasping the bat, the stitch is formed along a direction (bat extended direction) in which the largest centrifugal force is applied, so that the problem such as the deviation between the pieces of natural leather constituting the leather member having the both grain sides due to the centrifugal force can be prevented from being generated. 
     The sports glove according to the aspect of the present invention may include a finger portion that covers fingers, wherein the leather member is disposed on at least part of a palmar side of the finger portion. In such cases, the slipperiness can be suppressed in the finger portion in which particularly sensitive feeling is required when the player grasps the bat. 
     In the sports glove according to the aspect of the present invention, a stitch may be formed on the leather member. In such cases, the two pieces of natural leather constituting the leather member can be prevented from deviating when the player uses the sports glove. 
     The existence of the portion provided with the stitch can effectively suppress the slipperiness between the leather member and the hand and/or between the leather member and the bat when the player grasps the bat. 
     In the sports glove according to the aspect of the present invention, the stitch may be formed so as to be extended in a direction intersecting an extended direction of the finger portion in the leather member. In such cases, when the player swings the bat while grasping the bat, the stitch is formed along the direction (bat extended direction) in which the largest centrifugal force is applied, so that the problem such as the deviation between the pieces of natural leather constituting the leather member having the both grain sides due to the centrifugal force can be prevented from being generated. 
     According to the present invention, the hardly-slippery sports glove having the excellent fit can be realized. 
     The foregoing and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Exemplary embodiments of the present invention will be described below with reference to the drawings. In the following drawings, an identical or equivalent component is designated by the same reference numeral, and the repeated description is not made. 
     First Embodiment 
       FIG. 1  is a schematic diagram showing a palmar of a sports glove according to a first embodiment of the present invention.  FIG. 2  is a schematic diagram showing a backside of the sports glove of  FIG. 1 . Referring to  FIGS. 1 and 2 , the sports glove of the first embodiment will be described. 
     As shown in  FIGS. 1 and 2 , a palmar portion  2  and palmar sides of a middle finger  13 , a ring finger  14 , and a little finger  15  are made of both-grain-side natural leather (leather member in which two pieces of natural leather are overlapped such that grain sides are applied to a front side and a backside) that is of the feature of the present invention on a palmar of a sports glove  1 . A palmar side of an index finger  12 , a thumb  11 , and a thumb base portion  16  connected to thumb  11  are formed by a member (for example, natural leather or artificial leather) that is different from the both-grain-side natural leather. A hem rubber  7  is disposed on an end portion of a wrist insertion portion  5  of sports glove  1 . Side portions of index finger  12 , middle finger  13 , ring finger  14 , and little finger  15  are formed by finger gore portions  3  in which different natural leather, artificial leather, or cloth is disposed. Stitches  21   a  to  21   c  that are of seams are formed in palmar portion  2 . Stitches  21   a  to  21   c  are formed so as to be gradually brought closer to wrist insertion portion  5  from the thumb toward the little finger, while stitches  21   a  to  21   c  obliquely traverse palmar portion  2 . 
     A back portion  4  of sports glove  1  is made of natural leather or other pieces of synthetic fiber. On back portion  4 , a wrist belt  6  is disposed on hem rubber  7 , and one end of wrist belt  6  is detachable. 
     In sports glove  1  shown in  FIGS. 1 and 2 , the both-grain-side natural leather is applied to palmar portion  2  and the palmar sides of middle finger  13 , ring finger  14 , and little finger  15 . Therefore, the slipperiness can be reduced between the glove and the hand inside the glove, and the slipperiness can also be reduced between the glove and a member (such as a bat) that a gloved player grasps. 
     The generation of the problem such that the two pieces of leather constituting the both-grain-side natural leather are deviated during use can be suppressed by forming stitches  21   a  to  21   c . When sports glove  1  shown in  FIGS. 1 and 2  is used in grasping a baseball bat, because stitches  21   a  to  21   c  are formed along a direction (bat extended direction when the player swings the bat while wearing sports glove  1 ) in which the largest centrifugal force is applied during bat swing, the deviation between the two pieces of leather constituting the both-grain-side natural leather can be suppressed in the centrifugal direction by minimum necessary stitches  21   a  to  21   c.    
     As described above, in sports glove  1  shown in  FIGS. 1 and 2 , the slipperiness can be reduced between the hand and sports glove  1  as well as between the sports glove  1  and the member such as the bat, and the good fit can be provided because the grain side is applied to the surface in contact with the hand. 
       FIG. 3  is a schematic diagram showing a first modification of the sports glove of  FIGS. 1 and 2 . Referring to  FIG. 3 , a first modification of the sports glove of the first embodiment will be described.  FIGS. 3 to 30  correspond to  FIG. 1 , and  FIGS. 3 to 30  show the palmar side of the sports glove. 
     The sports glove  1  shown in  FIG. 3  basically has a configuration similar to that of the sports glove shown in  FIGS. 1 and 2 , but the sports glove  1  of  FIG. 3  differs from the sports glove of  FIGS. 1 and 2  in dispositions of the stitches  21   a  to  21   c  on the palmar side. That is, in sports glove  1  shown in  FIG. 3 , stitches  21   a  to  21   c  are formed so as to be extended toward wrist insertion portion  5  along the directions toward hem rubber  7  from leading end portions of middle finger  13 , ring finger  14 , and little finger  15 , that is, along the extended directions (orthogonal to a width direction) in central portions in the width directions of middle finger  13 , ring finger  14 , and little finger  15 . Therefore, the player is easy to grasp the bat by the hand while wearing sports glove  1  by forming stitches  21   a  to  21   c  in the direction substantially similar to that of the stitch on the back portion shown in  FIG. 2 . Further, stitches  21   a  to  21   c  are inserted in the direction of impact that is received by the hand grasping a grip portion of the bat when the bat contacts a ball (in striking the ball), which allows the deviation to be reduced between sports glove  1  and the bat or between the two pieces of leather constituting the both-grain-side natural leather. A stretch of the both-grain-side natural leather constituting palmar portion  2  can be reduced when sports glove  1  is used. 
       FIG. 4  is a schematic diagram showing a second modification of the sports glove of  FIGS. 1 and 2 . Referring to  FIG. 4 , a second modification of the sports glove of the first embodiment will be described. 
     Although sports glove  1  shown in  FIG. 4  basically has a configuration similar to that of sports glove  1  shown in  FIGS. 1 and 2 , sports glove  1  shown in  FIG. 4  differs from sports glove  1  shown in  FIGS. 1 and 2  in shapes of stitches  21   a  to  21   c  formed on the palmar-side leather member made of the both-grain-side natural leather. That is, in sports glove  1  shown in  FIG. 4 , stitches  21   a  to  21   c  are formed along fingers from the leading end portions of middle finger  13 , ring finger  14 , and little finger  15 , and stitches  21   a  to  21   c  are formed so as to be bent toward thumb  11  in palmar portion  2 . Therefore, as with sports glove  1  shown in  FIG. 3 , the player is easy to grasp the bat by the hand while wearing sports glove  1  by forming stitches  21   a  to  21   c  in the direction substantially similar to that of the stitch on the back portion shown in  FIG. 2 . 
       FIG. 5  is a schematic diagram showing a third modification of the sports glove of  FIGS. 1 and 2 . Referring to  FIG. 5 , a third modification of the sports glove of the first embodiment will be described. 
     Although sports glove  1  shown in  FIG. 5  basically has a configuration similar to that of sports glove  1  shown in  FIG. 4 , sports glove  1  shown in  FIG. 5  differs from sports glove  1  shown in  FIG. 4  in the shapes of stitches  21   a  to  21   c . That is, in sports glove  1  shown in  FIG. 5 , after stitches  21   a  to  21   c  are extended along fingers from the leading end portions to base portions of middle finger  13 , ring finger  14 , and little finger  15 , and stitches  21   a  to  21   c  are bent toward thumb  11  while brought closer one another in palmar portion  2 . Therefore, the effect similar to that of sports glove  1  shown in  FIG. 4  can be obtained. 
       FIG. 6  is a schematic diagram showing a fourth modification of the sports glove of  FIGS. 1 and 2 . Referring to  FIG. 6 , a fourth modification of the sports glove of the first embodiment will be described. 
     Although sports glove  1  shown in  FIG. 6  basically has a configuration similar to that of sports glove  1  shown in  FIGS. 1 and 2 , sports glove  1  shown in  FIG. 6  differs from sports glove  1  shown in  FIGS. 1 and 2  in the shapes of stitches formed on the palmar-side leather member made of the both-grain-side natural leather. That is, in sports glove  1  shown in  FIG. 6 , (as with the sports glove  1  shown in  FIG. 4 ), stitches  21   a  to  21   c  are formed so as to be extended to the bases from the leading end portions of middle finger  13 , ring finger  14 , and little finger  15 , and a fourth stitch  21   d  is formed so as to be extended along stitches  21   a  to  21   c  toward hem rubber  7  from a center of a side portion of little finger  15  of sports glove  1  in palmar portion  2 . The effect similar to that of sports glove  1  shown in  FIG. 4  can also be obtained in sports glove  1  shown in  FIG. 6 . Further, the deviation between the two pieces of natural leather constituting the leather member can effectively be suppressed by forming fourth stitch  21   d.    
       FIG. 7  is a schematic diagram showing a fifth modification of the sports glove of  FIGS. 1 and 2 . Referring to  FIG. 7 , a fifth modification of the sports glove of the first embodiment will be described. 
     Although sports glove  1  shown in  FIG. 7  basically has a configuration similar to that of sports glove  1  shown in  FIG. 3 , sports glove  1  shown in  FIG. 7  differs from sports glove  1  shown in  FIG. 3  in that the both-grain-side natural leather is also used in the palmar-portion-side surface of index finger  12  and a stitch  21   e  is formed toward the base from the leading end portion in index finger  12 . Therefore, the player grasps the bat more strongly because stitches  21   a  to  21   e  are formed for four fingers from index finger  12  to little finger  15 . Further, stitches  21   a  to  21   c  are inserted in the direction of impact that is received by the hand grasping the grip portion of the bat when the bat contacts the ball (in striking the ball), which allows the deviation to be reduced between sports glove  1  and the bat or between the two pieces of leather constituting the both-grain-side natural leather. The stretch of the both-grain-side natural leather constituting palmar portion  2  can be reduced when sports glove  1  is used. 
     In the fifth modification of the sports glove, as with the sports glove  1  shown in  FIG. 3 , the palmar side of index finger  12  may be formed by a member (such as normal natural leather in which the grain side is applied to the palmar portion or a floor side is applied to the palmar portion) different from the both-grain-side leather member. 
       FIG. 8  is a schematic diagram showing a sixth modification of the sports glove of  FIGS. 1 and 2 . Referring to  FIG. 8 , a sixth modification of the sports glove of the first embodiment will be described. 
     Although sports glove  1  shown in  FIG. 8  basically has a configuration similar to that of sports glove  1  shown in  FIG. 4 , sports glove  1  shown in  FIG. 8  differs from sports glove  1  shown in  FIG. 4  in the shapes of stitches  21   a  to  21   c . That is, in sports glove  1  shown in  FIG. 8 , stitches  21   a  to  21   c  are obliquely formed toward thumb  11  from side portions (side portions on the side opposite from thumb  11 ) of middle finger  13 , ring finger  14 , and little finger  15 . Therefore, during the bat swing, the deviation of the leather member (both-grain-side leather member) constituting palmar portion  2  can be reduced in a torque direction when the torque (force in a twist direction) is applied to the bat. 
       FIG. 9  is a schematic diagram showing a seventh modification of the sports glove of  FIGS. 1 and 2 . Referring to  FIG. 9 , a seventh modification of the sports glove of the first embodiment will be described. 
     Although sports glove  1  shown in  FIG. 9  basically has a configuration similar to that of sports glove  1  shown in  FIG. 3 , sports glove  1  shown in  FIG. 9  differs from sports glove  1  shown in  FIG. 3  in the shapes of stitches  21   a  to  21   c . That is, in sports glove  1  shown in  FIG. 9 , stitches  21   a  to  21   c  are formed only on middle finger  13 , ring finger  14 , and little finger  15 , respectively. A stitch  21   i  is formed in a portion corresponding to the base of each finger. Therefore, in the both-grain-side leather member disposed on the palmar side of the finger, the deviation between the two pieces of natural leather constituting the leather member can effectively be reduced by particularly forming stitches  21   a  to  21   c  on the palmar sides of the fingers. Further, stitches  21   a  to  21   c  are inserted in the direction of impact that is received by the hand grasping the grip portion of the bat when the bat contacts the ball (in striking the ball), which allows the deviation to be reduced between sports glove  1  and the bat on the palmar sides of middle finger  13 , ring finger  14 , and little finger  15 . 
       FIG. 10  is a schematic diagram showing an eighth modification of the sports glove of  FIGS. 1 and 2 . Referring to  FIG. 10 , an eighth modification of the sports glove of the first embodiment will be described. 
     Although sports glove  1  shown in  FIG. 10  basically has a configuration similar to that of sports glove  1  shown in  FIG. 9 , sports glove  1  shown in  FIG. 10  differs from sports glove  1  shown in  FIG. 9  in the shapes of stitches  21   a  to  21   c . That is, in sports glove  1  shown in  FIG. 10 , stitches  21   a  to  21   c  are obliquely formed toward thumb  11 , that is, from a side portion (side portions on the side opposite from thumb  11 ) of each finger to the other side portion located close to thumb  11 . Further, stitch  21   i  that is substantially perpendicular to the extended portion of each finger is formed in each of the base portions of middle finger  13 , ring finger  14 , and little finger  15 . Therefore, during the bat swing, the deviation of the leather member (both-grain-side leather member) constituting the palmar sides of middle finger  13 , ring finger  14 , and little finger  15  can be reduced in a torque direction when the torque (force in the twist direction) is applied to the bat. 
       FIG. 11  is a schematic diagram showing a ninth modification of the sports glove of  FIGS. 1 and 2 . Referring to  FIG. 11 , a ninth modification of the sports glove of the first embodiment will be described. 
     Although sports glove  1  shown in  FIG. 11  basically has a configuration similar to those of sports gloves  1  shown in  FIG. 10 , sports glove  1  shown in  FIG. 11  differs from sports gloves  1  shown in  FIG. 10  in that plural stitches  21   a  to  21   c  and  21   g  to  21   h  are formed on middle finger  13 , ring finger  14 , and little finger  15 , respectively. That is, in sports glove  1  shown in  FIG. 11 , each two of stitches  21   a  to  21   c  and  21   f  to  21   h  are obliquely formed from little finger  15  toward thumb  11  (so as to intersect the extended direction of each finger). Therefore, the effect similar to that of sports glove  1  shown in  FIG. 10  can also be obtained. That is, during the bat swing, the deviation of the leather member (both-grain-side leather member) constituting palmar sides of middle finger  13 , ring finger  14 , and little finger  15  can be reduced in the torque direction when the torque (force in the twist direction) is applied to the bat. The number of stitches on each of the fingers may be at least three, or the number of stitches may depend on the finger. 
       FIG. 12  is a schematic diagram showing a tenth modification of the sports glove of  FIGS. 1 and 2 . Referring to  FIG. 12 , a tenth modification of the sports glove of the first embodiment will be described. 
     Although sports glove  1  shown in  FIG. 12  basically has a configuration similar to that of sports glove  1  shown in  FIG. 9 , sports glove  1  shown in  FIG. 12  differs from sports glove  1  shown in  FIG. 9  in that obliquely formed stitches  21   f  to  21   h  (in the direction intersecting the extended direction of each finger) are formed toward thumb  11  from the side portion in the middle of each finger in addition to stitches  21   a  to  21   c  that are formed in the extended direction of each finger in each of middle finger  13 , ring finger  14 , and little finger  15 . Therefore, the effects provided by sports gloves  1  shown in  FIGS. 7 and 8  can simultaneously be obtained. 
       FIG. 13  is a schematic diagram showing an eleventh modification of the sports glove of  FIGS. 1 and 2 . Referring to  FIG. 13 , an eleventh modification of the sports glove of the first embodiment will be described. 
     Although sports glove  1  shown in  FIG. 13  basically has a configuration similar to that of sports glove  1  shown in  FIG. 3 , sports glove  1  shown in  FIG. 13  differs from sports glove  1  shown in  FIG. 3  in the shapes of stitches  21   a  to  21   c  formed in palmar portion  2 . That is, in sports glove  1  shown in  FIG. 17 , stitches  21   a  to  21   c  are substantially formed along the extended direction of each of middle finger  13 , ring finger  14 , and little finger  15  in palmar portion  2 , and stitches  21   a  to  21   c  are not extended to finger tip sides from stitches  21   i  formed in the base portions of middle finger  13 , ring finger  14 , and little finger  15 . From the different standpoint, in sports glove  1  shown in  FIG. 13 , stitches  21   a  to  21   c  are substantially linearly formed toward hem rubber  7  from the substantial centers of the base portions of middle finger  13 , ring finger  14 , and little finger  15  in palmar portion  2 . Therefore, stitches  21   a  to  21   c  are inserted in the direction of impact that is received by the hand grasping the grip portion of the bat when the bat contacts the ball (in striking the ball), which allows the deviation to be reduced between sports glove  1  and the bat or between the two pieces of leather constituting the both-grain-side natural leather. 
       FIG. 14  is a schematic diagram showing a twelfth modification of the sports glove of  FIGS. 1 and 2 . Referring to  FIG. 14 , a twelfth modification of the sports glove of the first embodiment will be described. 
     Although sports glove  1  shown in  FIG. 14  basically has a configuration similar to that of sports glove  1  shown in  FIG. 13 , sports glove  1  shown in  FIG. 14  differs from sports glove  1  shown in  FIG. 13  in the shapes of stitches  21   a  to  21   c . That is, in sports glove  1  shown in  FIG. 14 , stitches  21   a  to  21   c  are formed along fingers from the leading end portions of middle finger  13 , ring finger  14 , and little finger  15 , and stitches  21   a  to  21   c  are formed from the base portions of middle finger  13 , ring finger  14 , and little finger  15  so as to be gradually away from thumb  11 . Stitches  21   a  to  21   c  are formed so as to be curved. Therefore, during the bat swing, the deviation of the leather member (both-grain-side leather member) constituting palmar portion  2  can be reduced in the torque direction when the torque (force in the twist direction) is applied to the bat. 
       FIG. 15  is a schematic diagram showing a thirteenth modification of the sports glove of  FIGS. 1 and 2 . Referring to  FIG. 15 , a thirteenth modification of the sports glove of the first embodiment will be described. 
     As shown in  FIG. 15 , although sports glove  1  basically has a configuration similar to that of sports glove  1  shown in  FIGS. 1 and 2 , sports glove  1  shown in  FIG. 15  differs from sports glove  1  shown in  FIGS. 1 and 2  in the shapes of stitches formed on palmar portion  2 . In sports glove  1  shown in  FIG. 15 , stitches  21   a  to  21   c  are obliquely formed toward the little finger from index finger  12  so as to be gradually brought closer to hem rubber  7  in the region made of the both-grain-side natural leather, that is, in palmar portion  2 , middle finger  13 , ring finger  14 , and little finger  15 . Dead ends (end portions closest to hem rubber  7 ) of stitches  21   a  to  21   f  are formed so as to be connected to the side portion of little finger  15  of the glove. Therefore, during the bat swing, the deviation of the leather member (both-grain-side leather member) constituting palmar portion  2  can be reduced in the torque direction when the torque (force in the twist direction) is applied to the bat. 
       FIG. 16  is a schematic diagram showing a fourteenth modification of the sports glove of  FIGS. 1 and 2 . Referring to  FIG. 16 , a fourteenth modification of the sports glove of the first embodiment will be described. 
     Referring to  FIG. 16 , although sports glove  1  basically has a configuration similar to that of sports glove  1  shown in  FIG. 10 , sports glove  1  shown in  FIG. 15  differs from sports glove  1  shown in  FIG. 10  in the shapes of stitches  21   a  to  21   c  formed on middle finger  13 , ring finger  14 , and little finger  15 . That is, in sports glove  1  shown in  FIG. 16 , stitches  21   a  to  21   c  are formed along fingers from the leading end portions of middle finger  13 , ring finger  14 , and little finger  15 , and stitches  21   a  to  21   c  are formed so as to be obliquely brought closer to hem rubber  7  from the side portions, located closer to thumb  11 , of middle finger  13 , ring finger  14 , and little finger  15 . From the different standpoint, stitches  21   a  to  21   c  respectively intersect the extended directions of the fingers, and stitches  21   a  to  21   c  are obliquely formed so as to be gradually brought closer to the bases of the fingers from index finger  12  toward little finger  15 . Therefore, during the bat swing, the deviation of the leather member (both-grain-side leather member) constituting palmar portion  2  can be reduced in the torque direction when the torque (force in the twist direction) is applied to the bat. 
       FIG. 17  is a schematic diagram showing a fifteenth modification of the sports glove of  FIGS. 1 and 2 . Referring to  FIG. 17 , a fifteenth modification of the sports glove of the first embodiment will be described. 
     Referring to  FIG. 17 , although sports glove  1  basically has a configuration similar to that of sports glove  1  shown in  FIG. 14 , sports glove  1  shown in  FIG. 17  differs from sports glove  1  shown in  FIG. 14  in the shapes of stitches  21   a  to  21   c  formed in palmar portion  2 . That is, in sports glove  1  shown in  FIG. 17 , stitches  21   a  to  21   c  are formed so as to be obliquely and linearly extended from the central portions of the base portions of middle finger  13 , ring finger  14 , and little finger  15  (so as to be gradually away from thumb  11 ). Therefore, during the bat swing, the deviation of the leather member (both-grain-side leather member) constituting palmar portion  2  can be reduced in the torque direction when the torque (force in the twist direction) is applied to the bat. 
       FIG. 18  is a schematic diagram showing a sixteenth modification of the sports glove of  FIGS. 1 and 2 . Referring to  FIG. 18 , a sixteenth modification of the sports glove of the first embodiment will be described. 
     Referring to  FIG. 18 , although sports glove  1  basically has a configuration similar to that of sports glove  1  shown in  FIG. 17 , sports glove  1  shown in  FIG. 18  differs from sports glove  1  shown in  FIG. 17  in the shapes of stitches  21   a  to  21   c  formed in palmar portion  2 . That is, in sports glove  1  shown in  FIG. 18 , two stitches  21   a  and  21   b  are obliquely formed along fingers from the central portions of the base portions of middle finger  13  and ring finger  14  (so as to be gradually away thumb  11  as stitches  21   a  and  21   b  are brought closer to hem rubber  7 ). Therefore, during the bat swing, the deviation of the leather member (both-grain-side leather member) constituting palmar portion  2  can be reduced in the torque direction when the torque (force in the twist direction) is applied to the bat. 
       FIG. 19  is a schematic diagram showing a seventeenth modification of the sports glove of  FIGS. 1 and 2 . Referring to  FIG. 19 , a seventeenth modification of the sports glove of the first embodiment will be described. 
     Referring to  FIG. 19 , although sports glove  1  basically has a configuration similar to that of sports glove  1  shown in  FIGS. 1 and 2 , sports glove  1  shown in  FIG. 19  differs from sports glove  1  shown in  FIGS. 1 and 2  in that stitches  21   d  to  21   g  are also formed on middle finger  13 , ring finger  14 , and little finger  15 . That is, in sports glove  1  shown in  FIG. 24 , plural stitches  21   d  to  21   g  are formed in the directions intersecting the extended directions of the fingers in each of middle finger  13 , ring finger  14 , and little finger  15 . Therefore, during the bat swing, the deviation of the both-grain-side leather member can be reduced in the centrifugal direction by forming the stitch along the centrifugal direction. 
       FIG. 20  is a schematic diagram showing an eighteenth modification of the sports glove of  FIGS. 1 and 2 . Referring to  FIG. 20 , an eighteenth modification of the sports glove of the first embodiment will be described. 
     Referring to  FIG. 20 , although sports glove  1  basically has a configuration similar to that of sports glove  1  shown in  FIGS. 1 and 2 , sports glove  1  shown in  FIG. 20  differs from sports glove  1  shown in  FIGS. 1 and 2  in the shapes of stitches  21   a  to  21   c  formed on the palmar. That is, in sports glove  1  shown in  FIG. 20 , stitch  21   a  is obliquely formed toward hem rubber  7  from the side portion of thumb  11  of middle finger  13  so as to be gradually away from thumb  11 . On the other hand, stitches  21   b  and  21   c  are obliquely formed toward thumb base portion  16  from the side portions of ring finger  14  and little finger  15  on the side opposite from thumb  11 . That is, stitch  21   a  and stitches  21   b  and  21   c  are formed so as to intersect each other. Therefore, both the effects provided by sports gloves  1  shown in  FIGS. 8 and 15  can be obtained. 
       FIG. 21  is a schematic diagram showing a nineteenth modification of the sports glove of  FIGS. 1 and 2 . Referring to  FIG. 21 , a nineteenth modification of the sports glove of the first embodiment will be described.

Therefore, both the effects provided by sports gloves  1  shown in  FIGS. 8 and 15  can be obtained. Further, stitches  21   a  to  21   c  intersect one another at a point that is easily broken by the bat swing (little-finger-side (outside) region of palmar portion  2 ), which allows the point to be reinforced. 
     Second Embodiment 
       FIG. 22  is a schematic diagram showing a sports glove according to a second embodiment of the present invention. Referring to  FIG. 22 , a sports glove according to a second embodiment of the present invention will be described.

     As shown in  FIG. 22 , although sports glove  1  basically has a configuration similar to that of sports glove  1  shown in  FIGS. 1 and 2 , sports glove  1  shown in  FIG. 22  differs from sports glove  1  shown in  FIGS. 1 and 2  in that the member made of the both-grain-side natural leather is formed only in palmar portion  2 . That is, natural leather is used such that the grain side is disposed on the surface of thumb  11 , index finger  12 , middle finger  13 , ring finger  14 , and little finger  15  and the floor side is disposed inside the glove. Therefore, a seamed portion  30  is formed in the base portions of middle finger  13 , ring finger  14 , and little finger  15 . 
     The effect similar to that of sports glove  1  shown in  FIGS. 1 and 2  can be obtained in the configuration of  FIG. 22 . When the sensitive feeling is required in the fingertip, the both-grain-side natural leather is not used in each finger, but one piece of natural leather is used, so that loss of the feeling can be suppressed in the fingertip. 
     Any one of the stitch configurations shown in  FIGS. 3 to 21  may be applied to sports glove  1  shown in  FIG. 22 . 
     Third Embodiment 
       FIG. 23  is a schematic diagram showing a sports glove according to a third embodiment of the present invention. Referring to  FIG. 23 , a sports glove according to a third embodiment of the present invention will be described. 
     Referring to  FIG. 23 , although sports glove  1  basically has a configuration similar to that of sports glove  1  shown in  FIGS. 1 and 2 , sports glove  1  shown in  FIG. 23  differs from sports glove  1  shown in  FIGS. 1 and 2  in that the both-grain-side leather member is used only in the palmar sides of middle finger  13 , ring finger  14 , and little finger  15 . That is, in sports glove  1  shown in  FIG. 23 , the surface of palmar portion  2  is made of one piece of grain-side natural leather. Further, stitches  21   d  to  21   j  are formed on middle finger  13 , ring finger  14 , and little finger  15  so as to intersect the extended directions of the fingers (so as to be gradually brought closer to the base of the finger from thumb  11  toward little finger  15 ). The effect similar to those of sports gloves  1  shown in  FIGS. 1 and 2  can be obtained in sports glove  1  shown in  FIG. 23 . 
     The palmar side of index finger  12  may be formed by the both-grain-side leather member. Any one of the stitch configurations shown in  FIGS. 3 to 21  may be applied to sports glove  1  shown in  FIG. 23 . 
     Fourth Embodiment 
       FIG. 24  is a schematic diagram showing a sports glove according to a fourth embodiment of the present invention. Referring to  FIG. 24 , a sports glove according to a fourth embodiment of the present invention will be described. 
     Referring to  FIG. 24 , although sports glove  1  basically has a configuration similar to that of sports glove  1  shown in  FIGS. 1 and 2 , sports glove  1  shown in  FIG. 24  differs from sports glove  1  shown in  FIGS. 1 and 2  in that the both-grain-side leather member is used only in a thumb leading end portion  51 , an index finger leading end portion  52 , an middle finger leading end portion  53 , an ring finger leading end portion  54 , and an little finger leading end portion  55 . Thumb leading end portion  51 , index finger leading end portion  52 , middle finger leading end portion  53 , ring finger leading end portion  54 , and little finger leading end portion  55  are leading end portions of thumb  11 , index finger  12 , middle finger  13 , ring finger  14 , and little finger  15 . The effect similar to that of sports glove  1  shown in  FIGS. 1 and 2  can be obtained in sports glove  1  shown in  FIG. 24 . When sports glove  1  shown in  FIG. 24  is used in batting, a force of the hand (hand compression) can efficiently be transmitted to the bat because the both-grain-side leather member is used in the fingertip portion to which a pressure is applied during the bat swing. When sports glove  1  shown in  FIG. 24  is used in fielding, the both-grain-side natural leather is used in the finger portion to which the pressure is applied during the fielding, so that the deviation can be reduced between sports glove  1  and the glove in a catching motion. 
     Fifth Embodiment 
     Referring to  FIG. 25 , a sports glove according to a fifth embodiment of the present invention will be described. 
     Referring to  FIG. 25 , although sports glove  1  basically has a configuration similar to that of sports glove  1  shown in  FIGS. 1 and 2 , sports glove  1  shown in  FIG. 25  differs from sports glove  1  shown in  FIGS. 1 and 2  in the disposition of the both-grain-side leather member. That is, in sports glove  1  shown in  FIG. 25 , the both-grain-side leather members are used only in middle finger leading end portion  53 , ring finger leading end portion  54 , little finger leading end portion  55 , and a palmar-portion segment  56 . The palmar-portion segment  56  has a bent shape in which a horizontally extended portion and a vertically extended portion are connected. In the horizontally extended portion, the base portions of middle finger  13 , ring finger  14 , and little finger  15  are extended. The vertically extended portion is extended toward hem rubber  7  from the neighborhood of the base portion of little finger  15  of the horizontally extended portion. The effect similar to that of sports glove  1  shown in  FIGS. 1 and 2  can be obtained in sports glove  1  shown in  FIG. 25 . The fingertip on the palmar side, which is easily worn away by the use of sports glove  1 , and palmar-portion segment  56  are formed by the both-grain-side leather members. Therefore, the deviation can be reduced between the hand and the glove as well as between the glove and the member such as the bat, and the wear of sports glove  1  can be suppressed. 
     Sixth Embodiment 
     Referring to  FIG. 26 , a sports glove according to a sixth embodiment of the present invention will be described. 
     Referring to  FIG. 26 , although sports glove  1  basically has a configuration similar to that of sports glove  1  shown in  FIGS. 1 and 2 , sports glove  1  shown in  FIG. 26  differs from sports glove  1  shown in  FIGS. 1 and 2  in the disposition of the both-grain-side leather member. That is, in sports glove  1  shown in  FIG. 26 , the both-grain-side leather member is used only in palmar-portion segment  56  that is located below little finger  15  in palmar portion  2 . Palmar-portion segment  56  is disposed below little finger  15  in palmar portion  2 , and palmar-portion segment  56  is located while substantially facing thumb base portion  16  in the width direction of palmar portion  2 . In a planar shape, palmar-portion segment  56  has a substantially square shape. In four sides of the outer shape of palmar-portion segment  56 , the long side is extended in the substantially same direction as the extended direction of little finger  15 . In palmar-portion segment  56 , a seam (stitch) is formed in an outer circumferential portion thereof in order to fix palmar-portion segment  56 . Thus, in sports glove  1  according to the present invention, preferably the stitch used in the fixation is disposed inside the outer circumferential portion of the both-grain-side leather member. Palmar-portion segment  56  is formed by the both-grain-side leather member, so that the batter can more securely perform the bat grip in the hand located below (the grip end side of the bat) when gripping the bat. When the configuration shown in  FIG. 26  is adopted as the sports glove worn on the hand located below at the ready, the both-grain-side leather member is disposed on the portion (palmar-portion segment  56  of  FIG. 26 ) in which the force is particularly concentrated in the sports glove against the force of pushing back the bat by the centrifugal force during the bat swing and the impact of the batting. Therefore, the bat can securely be gripped during the bat swing or batting. 
     The portion in which the force is particularly concentrated in the sports glove can be specified by the following method. A detection sheet (for example, Presscale (ultra low-pressure: two-sheet type): product of FUJIFILM Business Supply Co., Ltd) whose color is changed in response to the pressure adheres to a grip tape of the bat, and a batter swings the bat while grasping the bat grip by bare hands. As a result, the color of the detection sheet is changed in the grip portion to which the pressure is applied from bare hands by the swing. In the hands of the batter (that is, sports glove), the portion in which the force is particularly concentrated during the swing can be specified from a positional relationship between the position of the color changed portion and the palmar portion of the hand by which the bat grip is grasped. 
     Seventh Embodiment 
     Referring to  FIG. 27 , a sports glove according to a seventh embodiment of the present invention will be described. 
     Referring to  FIG. 27 , although sports glove  1  basically has a configuration similar to that of sports glove  1  shown in  FIGS. 1 and 2 , sports glove  1  shown in  FIG. 27  differs from sports glove  1  shown in  FIGS. 1 and 2  in the disposition of the both-grain-side leather member. That is, in sports glove  1  shown in  FIG. 27 , the both-grain-side leather member is used only in a palmar-portion thumb-side fragment  61  that is located between index finger  12  and thumb base portion  16  (or thumb  11 ) in palmar portion  2 . Palmar-portion thumb-side fragment  61  is disposed from the base side of index finger  12  to thumb base portion  16 . A little-finger-side side portion of palmar-portion thumb-side fragment  61  has an outer circumferential shape that is substantially linearly extended toward thumb base portion  16  from between index finger  12  and middle finger  13 . Palmar-portion thumb-side fragment  61  is formed by the both-grain-side leather member, so that the batter can more securely perform the bat grip in the hand located above (the hitting side of the bat) when gripping the bat. When the configuration shown in  FIG. 27  is adopted as the sports glove worn on the hand located above at the ready, the both-grain-side leather member is disposed on the portion (palmar-portion thumb-side fragment  61  of  FIG. 27 ) in which the force is particularly concentrated in the sports glove against the force of pushing back the bat by the centrifugal force during the bat swing and the impact of the batting. Therefore, the bat can securely be gripped during the bat swing or batting. 
     For palmar-portion thumb-side fragment  61 , it can be confirmed that the force is concentrated during the bat swing by performing the experiment with the detection sheet as described in the sixth embodiment. 
     Palmar-portion thumb-side fragment  61  can be formed any planar shape. For example, palmar-portion thumb-side fragment  61  may be formed in the shape in which the width (in the direction toward the wrist from the fingers) is increased toward the thumb from the little finger. 
     Eighth Embodiment 
     Referring to  FIG. 28 , a sports glove according to an eighth embodiment of the present invention will be described.

That is, in sports glove  1  shown in  FIG. 28 , the both-grain-side leather members are used in a middle-finger palmar-side fragment  63 , a ring-finger palmar-side fragment  64 , and a little-finger palmar-side fragment  65  in addition to palmar-portion fragment  56  located below little finger  15  in palmar portion  2 . Middle-finger palmar-side fragment  63 , ring-finger palmar-side fragment  64 , and little-finger palmar-side fragment  65  are located on the palmar sides of middle finger  13 , ring finger  14 , and little finger  15 . Middle-finger palmar-side fragment  63 , ring-finger palmar-side fragment  64 , and little-finger palmar-side fragment  65  are extended from the leading end portions of middle finger  13 , ring finger  14 , and little finger  15  to regions between second joint from the leading end portion and third joint, respectively. When the batter is at the ready, middle-finger palmar-side fragment  63 , ring-finger palmar-side fragment  64 , and little-finger palmar-side fragment  65  that are disposed across the bat from palmar-portion fragment  56  are also formed by the both-grain-side leather members, so that the batter can more stably perform the bat grip. 
     Referring to  FIG. 29 , a first modification of the sports glove of  FIG. 28  will be described. Referring to  FIG. 29 , although sports glove  1  basically has a configuration similar to that of sports glove  1  shown in  FIG. 28 , sports glove  1  shown in  FIG. 29  differs from sports glove  1  shown in  FIG. 28  in that palmar-portion thumb-side fragment  61  is formed by the both-grain-side leather member instead of palmar-portion fragment  56  shown in  FIG. 28 . The configuration of palmar-portion thumb-side fragment  61  of sports glove  1  shown in  FIG. 29  is basically similar to that of palmar-portion thumb-side fragment  61  of sports glove  1  shown in  FIG. 27 . In the configuration of sports glove  1  shown in  FIG. 29 , when the batter is at the ready, middle-finger palmar-side fragment  63 , ring-finger palmar-side fragment  64 , and little-finger palmar-side fragment  65  that are disposed across the bat from palmar-portion thumb-side fragment  61  are also formed by the both-grain-side leather members, so that the batter can more stably perform the bat grip. 
     Referring to  FIG. 30 , a second modification of the sports glove of  FIG. 28  will be described. Referring to  FIG. 30 , although sports glove  1  basically has a configuration similar to that of sports glove  1  shown in  FIG. 28 , sports glove  1  shown in  FIG. 30  differs from sports glove  1  shown in  FIG. 28  in that palmar-portion thumb-side fragment  61  is formed by the both-grain-side leather member in addition to palmar-portion fragment  56  shown in  FIG. 28 . The configuration of palmar-portion thumb-side fragment  61  of sports glove  1  shown in  FIG. 30  is basically similar to that of palmar-portion thumb-side fragment  61  of sports glove  1  shown in  FIG. 27 . In the configuration of sports glove  1  shown in  FIG. 30 , when the batter is at the ready, middle-finger palmar-side fragment  63 , ring-finger palmar-side fragment  64 , and little-finger palmar-side fragment  65  that are disposed across the bat from palmar-portion fragment  56  and palmar-portion thumb-side fragment  61  are also formed by the both-grain-side leather members, so that the batter can more stably perform the bat grip. When the batter wears the sports glove on the hand (lower side) located closer to the grip end of the bat at the ready or when the batter wears the sports glove on the hand (upper side) located farther away from the grip end of the bat at the ready, the batter can more stably perform the bat grip. That is, the batter can more stably perform the bat grip in both the hands. 
     Middle-finger palmar-side fragment  63 , ring-finger palmar-side fragment  64 , and little-finger palmar-side fragment  65  that are formed by the both-grain-side leather members are disposed in sports glove  1 . Alternatively, only two of one of middle-finger palmar-side fragment  63 , ring-finger palmar-side fragment  64 , and little-finger palmar-side fragment  65  may be disposed. Middle-finger palmar-side fragment  63 , ring-finger palmar-side fragment  64 , and little-finger palmar-side fragment  65  may be disposed so as to be extended only to the leading end portions of middle finger  13 , ring finger  14 , and little finger  15 , or middle-finger palmar-side fragment  63 , ring-finger palmar-side fragment  64 , and little-finger palmar-side fragment  65  may be disposed so as to be extended to between a first joint from the leading end and a second joint. Middle-finger palmar-side fragment  63 , ring-finger palmar-side fragment  64 , and little-finger palmar-side fragment  65  may be formed at different positions or in different sizes in middle finger  13 , ring finger  14 , and little finger  15 , respectively. Middle-finger palmar-side fragment  63 , ring-finger palmar-side fragment  64 , and little-finger palmar-side fragment  65  may be formed so as to be extended toward the base sides of the fingers from not the leading end portions of middle finger  13 , ring finger  14 , and little finger  15 , but the middle of the finger. Plural middle-finger palmar-side fragments  63 , ring-finger palmar-side fragments  64 , and little-finger palmar-side fragments  65  may be disposed on middle finger  13 , ring finger  14 , and little finger  15 , respectively. In the configurations of palmar-portion fragment  56  and palmar-portion thumb-side fragment  61 , plural independent fragments (fragments formed by the both-grain-side leather members) may be dispersed. 
     Ninth Embodiment 
     Referring to  FIG. 31 , a sports glove according to a ninth embodiment of the present invention will be described. 
     Referring to  FIG. 31 , although sports glove  1  basically has a configuration similar to that of sports glove  1  shown in  FIG. 26 , sports glove  1  shown in  FIG. 31  differs from sports glove  1  shown in  FIG. 26  in a shape of a palmar-portion fragment  66  formed by the both-grain-side leather member. In palmar-portion fragment  66 , an upper end (end portion on the fingers) is extended from below little finger  15  to below middle finger  13  in palmar portion  2 , and an outer circumference of the end portion of thumb  11  is inclined toward the wrist from the base of index finger  12  (so as to be gradually brought closer to little finger  15 ). From the different standpoint, palmar-portion fragment  66  is formed such that the width (in a longitudinal direction (direction from the fingers to the wrist) of palmar portion  2 ) of palmar-portion fragment  66  is gradually increased from thumb  11  toward little finger  15 . The end portion of little finger  15  of palmar-portion fragment  66  is extended to the end portion on little finger  15  of palmar portion  2 . Therefore, when the batter wears sports glove  1  on the hand that becomes an axis of the bat swing, the batter can improve the bat grip force in a region (end portion on the little finger of palmar portion  2 ) below little finger  15 . The region below little finger  15  becomes the axis of the bat swing. 
     Tenth Embodiment 
     Referring to  FIG. 32 , a sports glove according to a tenth embodiment of the present invention will be described. 
     Referring to  FIG. 32 , although sports glove  1  basically has a configuration similar to that of sports glove  1  shown in  FIGS. 1 and 2 , sports glove  1  shown in  FIG. 32  differs from sports glove  1  shown in  FIGS. 1 and 2  in the disposition of the both-grain-side leather member. That is, in sports glove  1  shown in  FIG. 32 , the both-grain-side leather member is used only in a palmar-portion fragment  76  in palmar portion  2 . Palmar-portion fragment  76  is located from the base portion of index finger  12  to below little finger  15 . Palmar-portion fragment  76  is formed so as to be extended from the base portion of index finger  12  toward below little finger  15 , and palmar-portion fragment  76  may have a substantially rectangular planar shape. Palmar-portion fragment  76  is a region to where the largest pressure is applied to the hand during the bat swing, so that the bat grip can more securely be performed by disposing the both-grain-side leather member in palmar-portion fragment  76 . When palmar-portion fragment  76  is formed by the both-grain-side leather member, a difference in thickness is generated between palmar-portion fragment  76  and portions except for palmar-portion fragment  76 . Accordingly, palmar-portion fragment  76  is securely fixed when the batter grips the bat. The width (in the direction from the fingers toward the wrist) of palmar-portion fragment  76  is equal to or lower than an outer circumferential length of the bat grip portion, preferably the width is lower than 50% of the outer circumferential length. Specifically, preferably the width ranges from 1 mm to 35 mm, more preferably the width ranges from 10 mm to 30 mm As to the difference in thickness between palmar-portion fragment  76  and the portions except for palmar-portion fragment  76 , the thickness of palmar-portion fragment  76  is larger than those of the portions except for palmar-portion fragment  76  by at least 0.5 mm Therefore, the bat grip is easy to perform, and the stable swing can be performed. 
     Eleventh Embodiment 
     Referring to  FIG. 33 , a sports glove according to an eleventh embodiment of the present invention will be described. 
     Referring to  FIG. 33 , although sports glove  1  basically has a configuration similar to that of sports glove  1  shown in  FIG. 32 , sports glove  1  shown in  FIG. 33  differs from sports glove  1  shown in  FIG. 32  in the disposition of the both-grain-side leather member. That is, in sports glove  1  shown in  FIG. 33 , the both-grain-side leather member is used not in palmar-portion fragment  76  located from the base portion of index finger  12  to below little finger  15  in palmar portion  2 , but in a palmar-portion fragment  77  and the palmar-portion-side surface from index finger  12  to little finger  15 . Palmar-portion fragment  77  and the palmar-portion-side surface from index finger  12  to little finger  15  are a palmar-side surface except for palmar-portion fragment  76 . Palmar-portion fragment  76  is formed by a member that is not the both-grain-side leather member. In the configuration of sports glove  1  shown in  FIG. 33 , the difference in thickness can be generated between palmar-portion fragment  77  and palmar-portion fragment  76 , which allows the bat to be securely gripped. At this point, in the difference in thickness between palmar-portion fragment  76  and portions except for palmar-portion fragment  76 , the thickness of palmar-portion fragment  76  is lower than the portions except for palmar-portion fragment  76  by at least 0.5 mm, the bat grip is easy to perform, and the stable swing can be performed. 
     Twelfth Embodiment 
     Referring to  FIG. 34 , a sports glove according to a twelfth embodiment of the present invention will be described. 
     Referring to  FIG. 34 , although sports glove  1  basically has a configuration similar to that of sports glove  1  shown in  FIGS. 1 and 2 , sports glove  1  shown in  FIG. 34  differs from sports glove  1  shown in  FIGS. 1 and 2  in the disposition of the both-grain-side leather member. That is, in sports glove  1  shown in  FIG. 34 , the both-grain-side leather members are disposed only in middle-finger palmar-side fragment  63 , ring-finger palmar-side fragment  64 , and little-finger palmar-side fragment  65  that are located on the palmar sides of middle finger  13 , ring finger  14 , and little finger  15 . Further, in middle-finger palmar-side fragment  63 , ring-finger palmar-side fragment  64 , and little-finger palmar-side fragment  65 , joint width narrowed portions  81  are formed at two points corresponding to the joints of the finger. The width of the both-grain-side leather member is narrowed in joint width narrowed portion  81 . A joint aid portion  82  made of normal leather member or other fiber is formed adjacent to joint width narrowed portion  81 . Therefore, the bat can securely be gripped by the use of the both-grain-side leather member, and resistance of the glove is reduced when the finger is bent, and the ease of the finger motion can be improved in wearing sports glove  1 . The both-grain-side leather member may be disposed on the palmar side of index finger  12  or thumb  11 . The both-grain-side leather member may be disposed on the palmar side of any one of thumb  11  to little finger  15 . 
     Thirteenth Embodiment 
     Referring to  FIG. 35 , a sports glove according to a thirteenth embodiment of the present invention will be described. 
     Referring to  FIG. 35 , although sports glove  1  basically has a configuration similar to that of sports glove  1  shown in  FIG. 34 , sports glove  1  shown in  FIG. 35  differs from sports glove  1  shown in  FIG. 34  in the disposition of the both-grain-side leather member. That is, in sports glove  1  shown in  FIG. 35 , the both-grain-side leather members are disposed only in middle-finger palmar-side fragment  63 , ring-finger palmar-side fragment  64 , and little-finger palmar-side fragment  65  that are located on the palmar sides of middle finger  13 , ring finger  14 , and little finger  15 . Further, middle-finger palmar-side fragment  63  includes a middle-finger leading end portion  63   a , a middle-finger intermediate portion  63   b , and a middle-finger base portion  63   c . Middle-finger leading end portion  63   a , middle-finger intermediate portion  63   b , and middle-finger base portion  63   c  are separated from one another by joint aid portions  82 . Ring-finger palmar-side fragment  64  includes a ring-finger leading end portion  64   a , ring-finger intermediate portion  64   b , and a ring-finger base portion  64   c . Ring-finger leading end portion  64   a , ring-finger intermediate portion  64   b , and ring-finger base portion  64   c  are separated from one another by joint aid portions  82 . Little-finger palmar-side fragment  65  includes a little-finger leading end portion  65   a , a little-finger intermediate portion  65   b , and a little-finger base portion  65   c . Little-finger leading end portion  65   a , little-finger intermediate portion  65   b , and little-finger base portion  65   c  are separated from one another by joint aid portions  82 . Joint aid portion  82  is formed by a member that is more flexible than the both-grain-side leather member (in addition, more preferably the thickness of joint aid portion  82  is lower than that of the both-grain-side leather member). For example, any material such as normal chemical fiber and single-grain-side leather member can be used as the material for joint aid portion  82 . In the configuration of sports glove  1  shown in  FIG. 35 , the effect similar to that of sports glove  1  shown in  FIG. 34  can be obtained. 
     Fourteenth Embodiment 
     Referring to  FIG. 36 , a sports glove according to a fourteenth embodiment of the present invention will be described. 
     Referring to  FIG. 36 , although sports glove  1  basically has a configuration similar to that of sports glove  1  shown in  FIGS. 1 and 2 , sports glove  1  shown in  FIG. 36  differs from sports glove  1  shown in  FIGS. 1 and 2  in the disposition of the both-grain-side leather member. That is, in sports glove  1  shown in  FIG. 36 , palmar-portion fragment  56  is formed by the both-grain-side leather member such that the whole palmar portion  2  except for thumb base portion  16  is covered with palmar-portion fragment  56 . From the different standpoint, in palmar-portion fragment  56 , a planar end portion on the finger reaches bases of middle finger  13  to little finger  15 . An outer shape of the planar end portion on the thumb is extended toward the thumb from between index finger  12  and middle finger  13 , the outer shape is curved along the outer circumference of thumb base portion  16 , and the outer shape reaches hem rubber  7  of the wrist portion. The planar end portion on the wrist reaches hem rubber  7 , and the outer shape of the end portion on the wrist is substantially linearly formed along the upper end of hem rubber  7 . Stitches  21   a  to  21   c  are formed in palmar-portion fragment  56 . Stitches  21   a  to  21   c  are inclined from index finger  12  toward little finger  15  so as to be gradually brought closer to wrist (side of hem rubber  7 ) from the fingers. In the configuration of sports glove  1  shown in  FIG. 36 , the bat grip can securely be performed. 
     Fifteenth Embodiment 
     Referring to  FIG. 37 , a sports glove according to a fifteenth embodiment of the present invention will be described. 
     Referring to  FIG. 37 , although sports glove  1  basically has a configuration similar to that of sports glove  1  shown in  FIGS. 1 and 2 , sports glove  1  shown in  FIG. 37  differs from sports glove  1  shown in  FIGS. 1 and 2  in the disposition of the both-grain-side leather member. That is, in sports glove  1  shown in  FIG. 37 , the whole surface on the palmar (that is, palmar portion  2 , palmar side surfaces of thumb  11  to little finger  15 , and thumb base portion  16 ) is formed by the both-grain-side leather member. In the configuration of sports glove  1  shown in  FIG. 37 , the bat grip can securely be performed. 
     Sixteenth Embodiment 
     Referring to  FIG. 38 , a sports glove according to a sixteenth embodiment of the present invention will be described. 
     Referring to  FIG. 38 , although sports glove  1  basically has a configuration similar to that of sports glove  1  shown in  FIG. 36 , sports glove  1  shown in  FIG. 38  differs from sports glove  1  shown in  FIG. 36  in the disposition of the both-grain-side leather member. That is, in sports glove  1  shown in  FIG. 38 , palmar-portion fragment  56  shown in  FIG. 36  is formed by the both-grain-side leather member, a gore portion that covers a side surface of each finger constitutes a both-grain-side finger gore portion  83  formed by the both-grain-side leather member. Therefore, because the deviation between the fingers can be suppressed during the bat grip, the assured state of the bat grip can be maintained during the bat swing. Only part of the gore portion that covers the side surface of each finger in a lengthwise direction (extended direction of the finger) may constitute both-grain-side finger gore portion  83  formed by the both-grain-side leather member. Both-grain-side finger gore portion  83  may be disposed only for the specific finger. 
     Referring to  FIG. 39 , a first modification of the sports glove of  FIG. 38  will be described. Referring to  FIG. 39 , although sports glove  1  basically has a configuration similar to that of sports glove  1  shown in  FIG. 38 , sports glove  1  shown in  FIG. 39  differs from sports glove  1  shown in  FIG. 38  in the disposition of the both-grain-side leather member. That is, in sports glove  1  shown in  FIG. 9 , in addition to both-grain-side finger gore portion  83  shown in  FIG. 38 , the whole surface on the palmar is formed by the both-grain-side leather member like sports glove  1  shown in  FIG. 37 . Therefore, the effect provided by sports glove  1  shown in  FIG. 37  can be obtained in addition to the effect provided by sports glove  1  shown in  FIG. 38 . 
     Referring to  FIG. 40 , a second modification of the sports glove of  FIG. 38  will be described. Referring to  FIG. 40 , although sports glove  1  basically has a configuration similar to that of sports glove  1  shown in  FIG. 38 , sports glove  1  shown in  FIG. 40  differs from sports glove  1  shown in  FIG. 38  in that only the gore portion located in one of side surfaces of the finger constitutes both-grain-side finger gore portion  83 . In such cases, the relatively thick both-grain-side leather member is used only in one of the side surfaces, and the other side surface is made of another relatively flexible material. Therefore, the ease of the finger motion can be improved (that is, the fit of sports glove  1  can be improved) while the effect by sports glove  1  shown in  FIG. 38  is maintained to some extent. In sports glove  1  shown in  FIG. 40 , both-grain-side finger gore portions  83  are disposed on the side surfaces closer to the thumb of middle finger  13  to little finger  15 . Alternatively, both-grain-side finger gore portion  83  may be disposed on the opposite side (side surface on the little finger), or the direction in which both-grain-side finger gore portion  83  is disposed may be changed in each finger. Both-grain-side finger gore portion  83  may be disposed on not all the fingers but the specific finger. 
     EXAMPLE 
     The following experiments were performed to confirm the effects of the sports glove according to the present invention. 
     (Samples) 
     In order to confirm the effect of the sports glove according to the present invention, a glove with the palmar portion being formed by the grain side of the normal natural leather, a glove with the palmar portion being formed by the floor side of the normal natural leather, and a glove with the palmar portion being formed by a resin and artificial leather were prepared in addition to the sports glove shown in  FIGS. 1 and 2  of the present invention. 
     (Experimental Apparatus) 
     A measuring apparatus  40  shown in  FIG. 41  is a torque measuring apparatus. In measuring apparatus  40 , support members  43  are disposed on a base member  47  while facing each other, and a shaft  42  is rotatably supported in support members  43 . A bat grip portion  44  is connected and fixed to one end of shaft  42 . A grip tape  45  is disposed on the surface of grip portion  44 . A torque sensor  41  is connected to the other end of shaft  42 . A control unit  46  is connected to torque sensor  41  in order to record output from torque sensor  41 . 
     Two kinds of grip portions  44  having different materials of grip tapes  45  were prepared. That is, relatively hardly-slippery grip tape  45  was used as a grip tape A. Grip tape  45  that was relatively more slippery than grip tape A was used as a grip tape B. 
     (Experimental Method) 
     For eight testers, the torque was measured when the measuring apparatus shown in  FIG. 26  was rotated counterclockwise while the grip portion of the measuring apparatus is gripped by the four kinds of the gloves and bare hands. The measurement was performed for each of the two kinds of the grip portions having the different grip tapes. 
     (Results) 
     Tables 1 and 2 show the torque measurement results of the testers in the grip portions in which grip tape A and grip tape B are used. Table 1 is the result when the grip portion of grip tape A is used, and Table 2 is the result when the grip portion of grip tape B is used.

       FIGS. 42 and 43  show average torque values in the result in the kinds of the sports gloves. 
     In the graphs shown in  FIGS. 42 and 43 , a horizontal axis indicates the kind of the glove used, and a vertical axis indicates the torque. The torque in the vertical axis has a unit of Nm. In the horizontal axes of  FIGS. 42 and 43 , the letter A designates the case where the sports glove is made of one piece of natural leather and the grain side is applied to the palmar portion. The letter B in the horizontal axes designates the case where the sports glove of the present invention is used. The letter C in the horizontal axes designates the case where the sports glove with the floor side being applied to the palmar portion surface is used. The letter D in the horizontal axes designates the case where the sports glove with the palmar portion being formed by the resin and the artificial leather is used. The letter E in the horizontal axes designates the case where the grip portion is grasped by bare hands. 
     As can be seen from  FIGS. 42 and 43 , in each grip tape, the torque is maximized when the sports glove of the present invention is used. That is, it is shown that the hard-slipperiness is realized when the sports glove of the present invention is used. 
     The present invention is advantageously applied to the sports glove, particularly to the sports glove that is worn in the batting of baseball and softball. 
     Although the present invention has been described and illustrated in detail, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, the scope of the present invention being interpreted by the terms of the appended claims.
