Title: Medicine applicator, medicine application kit, and pressing tool for medicine applicator

Description:
TECHNICAL FIELD 
     The present invention relates to a medicine applicator, a medicine application kit, and a pressing tool for a medicine applicator for applying a medicine or a cosmetic such as an antiphlogistic agent or a sunblock, particularly, to a medicine applicator, a medicine application kit, and a pressing tool for a medicine applicator suitable for a person to be applied to apply a medicine or a cosmetic by himself or herself. 
     BACKGROUND ART 
     In the related art, many assist tools have been proposed with which a person to be applied applies an ointment, a medicine solution, or a cosmetic such as a sunblock or to affix a compress to the back and other sites that are out of the hands of the person to be applied, by himself or herself. In many assist tools, an application portion or an affixing portion for applying a liquid agent is formed at a scratching portion of a so-called backscratcher. 
     Patent Document 1 discloses one example of a medicine applicator of the related art. This publication provides a medicine application device with which a person applies a medicine to a lesion on a site such as the back that is difficult for the hands to reach, disinfects the lesion, wipes out pus, or wipes out blood by himself or herself. Namely, the medicine application device includes a handle and a medicine application portion at one end and the other end of a curved arm, respectively, and a stop plate for clamping is provided at an upper portion of the medicine application portion. During its use, tissue paper, gauze, absorbent cotton, or the like is laid under the medicine application portion, and is valley-folded along folding lines to wrap the tissue paper, gauze, absorbent cotton, or the like around the medicine application portion to fold both ends on an upper surface of the medicine application portion. Thereafter, the medicine application portion is covered with the stop plate for clamping, and the stop plate for clamping is fixed with an engaging claw. 
     Patent Document 2 discloses an example of a home medical assist tool of the related art that can easily affix or peel a medical patch to or off from a lesion of the back. In the medical assist tool described in this publication, a medical patch fixing tool has an integral structure in which an upper portion of a curved presser plate including a peeling portion at a lower side portion and an upper portion of a clamping plate including a claw are coupled to each other by a shaft including a spring. A support arm including a grip portion is structured to be connected by a support arm attachment portion, so that the support arm is attachable and detachable or is adjustable in angle.

     DISCLOSURE OF THE INVENTION 
     Problem to be Solved by the Invention 
     In the applicator of the related art described in Patent Document 1, instead of a scratching portion of a backscratcher, an application member is provided at an end portion of the applicator having a backscratcher shape. Then, a medicine is impregnated or applied to the application member and is transferred to the skin of a person to be applied. With such a configuration, the person to be applied can feel as if he or she applies a medicine to a site of the back that are out of the hands, with his or her own hands. 
     In the application device described in Patent Document 1, the medicine application portion having an elliptical shape is formed at a tip portion of the curved arm, and the stop plate for clamping that is rotatably provided at a base portion of the medicine application portion is rotated and pressed against tissue paper, cotton, gauze, or the like (hereinafter, also referred to as a treatment article) disposed to wrap the medicine application portion, and is fixed with the engaging claw provided at an end portion of the stop plate. In the application device, the treatment article such as tissue paper, cotton, or gauze can be reliably held, but the ratio or effective area of a portion used for application or wiping to the entirety of the treatment article is reduced. A standard product such as cut cotton or cotton puff that is a typical example of the treatment article is approximately 5 cm square, and when folded for clamping, the effective area that can be used for application or wiping is drastically reduced, so that the application time is lengthened while only a small portion of the skin can be treated (applied or wiped out) at once, and the size of a portion that are discarded without being used for treatment increases. 
     Patent Document 2 discloses that the medical patch is gripped and conveyed to the affixing portion by the clamping plate including the claw; and when the medical path reaches an affixing position, the gripping by the clamping plate is stopped, and the medical path is pressed and affixed by the presser plate. Since the medical assist tool described in Patent Document 2 is mainly intended to affix or peel the medical patch, in the case of applying a medicine using a treatment article such as cut cotton or cotton puff, no consideration is given to making the effective area used for applying the medicine as large as possible while reliably holding the cut cotton or cotton puff. 
     The invention is conceived in view of defects of an applicator of the related art with which a person to be applied applies a medicine solution to the back by himself or herself, and an object of the invention is to provide a medicine applicator configured by replacing a scratching portion of a backscratcher including an arm with an applicator for the medicine solution, which can attachably and detachably hold a disposable treatment article used for application and which can make an effective area used for applying the treatment article as large as possible. 
     Means for Solving Problem 
     In order to achieve the foregoing object, a medicine applicator of the invention is characterized by including: an arm extending in a longitudinal direction, of which one end portion side is used for gripping; and a pedestal portion disposed on the arm to be substantially parallel to the longitudinal direction of the arm. The medicine applicator is provided with a pair of pressing tools that attachably and detachably hold an application member on the pedestal portion, and the pair of pressing tools include a repulsive tool that generates a pressing force to bring the application member into contact with the pedestal portion. 
     In the invention, the “arm of which one end portion side is used for gripping” can also be paraphrased as, for example, the “arm on one end side of which a grip portion is formed”. 
     In addition, “being substantially parallel” implies not only a state where the longitudinal direction of the arm and the pedestal portion are completely parallel to each other with no angle therebetween, but also a state where the longitudinal direction of the arm and the pedestal portion are mostly parallel to each other with a slight angle therebetween. Specifically, for example, “being substantially parallel” implies a state where the longitudinal direction of the arm and the pedestal portion are completely or mostly parallel to each other with an angle of approximately 0° to 7° therebetween. 
     In addition, the mode in which the application member is disposed includes, for example, a mode in which the application member is disposed to cover at least a part of a bottom surface side of the pedestal portion, and the like. 
     In addition, the “application member” implies any member as long as the member can hold an application agent such as a medicine or a cosmetic on a surface or inside and can be disposed on the pedestal portion. For example, the “application member” implies any one of cotton, fabric, non-woven fabric, and paper made of natural fibers, chemical fibers, and the like, and more specifically, implies, for example, any one of absorbent cotton such as cotton puff or cut cotton, tissue paper, gauze, and the like. In addition, the “application member” implies both a disposable member and a non-disposable member. In addition, the term “application member” can also be paraphrased as, for example, a “treatment article”. 
     In addition, the “repulsive tool that generates a pressing force to bring the application member into contact with the pedestal portion” implies, more specifically, for example, the “repulsive tool that brings the application member into contact with the pedestal portion to generate a pressing force of the application member on the pedestal portion”. In addition, the “pressing tool” implies, for example, clamping means such as clips that can clamp and hold the application member between the clamping means and the pedestal portion. 
     Therefore, this characteristic of the invention can be paraphrased as, for example, as follows. 
     A medicine applicator includes: an arm extending in a longitudinal direction, on one end side of which a grip portion is formed; and a pedestal portion disposed on the arm to be completely or mostly parallel to the longitudinal direction of the arm. The medicine applicator is provided with a pair of clips that attachably and detachably hold a disposable or non-disposable treatment article disposed to cover at least a part of a bottom surface side of the pedestal portion, and the pair of clips include a repulsive tool that brings the treatment article into contact with the pedestal portion to generate a pressing force of the treatment article on the pedestal portion. 
     Then, in this characteristic of the invention, the medicine applicator may include a finger contact portion for assisting an operation of the pressing tools or for operating the pressing tools. 
     In addition, “assisting an operation of the pressing tools” means assisting an opening and closing operation of the pressing tools by adjunctively using the finger contact portion in a case where a user tries to pinch knob portions of the pair of pressing tools with fingers but the opening and closing position of the pressing tools cannot be stably controlled when the pressing tools are opened and closed, and “operating the pressing tools” means only the same usage manner as a usage manner to be described in the following “modes for carrying out the invention” without pinching the knob portions of the pressing tools from the beginning. Namely, it is meant that the finger contact portion disposed to correspond to each of the pressing tools should be used when the pressing tools are opened and closed. 
     In this characteristic, the pedestal portion may be disposed at a substantially central portion of the arm, and both end portions of the arm may be portions used for gripping, namely, grip portions. In addition, the pedestal portion may be disposed at the other end portion of the arm or in the vicinity of the other end portion, and a secondary arm (in the present specification, also referred to as an “assist arm”) that extends the arm may be attachably and detachably attached to the other end side of the arm to form a second grip portion at an end portion of the secondary arm (namely, to also use the end portion of the secondary arm for gripping). 
     In this characteristic, an end portion of each of the pair of pressing tools (clips or the like) may be formed as a knob portion, and the repulsive tool may be a coil spring (for example, a spring referred to as a kick spring, a torsional spring, a torsional coil spring, or the like) of which an end portion is in contact with a back surface side of the knob portion of each of the pressing tools (clips or the like) and of which a coil-shaped portion is wound around a shaft provided in the arm, and the repulsive tool may be a leaf spring of which both end portions are fixed to the back surface sides of the knob portions of the respective pressing tools (clips or the like). Further, the pedestal portion may be held to be swingable with respect to the arm. 
     Incidentally, “being wound” implies, for example, any one of a mode in which the repulsive tool is closely wound around an object such as a shaft or a pin while contacting the object, a mode in which the repulsive tool is wound around the object with a play (or a clearance) between the repulsive tool and the object, and the like. 
     In this characteristic, the repulsive tool may be fixed only to the pressing tools without being held by the arm. 
     In this characteristic, the arm may be provided with a male screw or a female screw, the secondary arm may be provided with a female screw or a male screw, and the secondary arm may be attachably and detachably attached to the arm by screwing the male screw or the female screw of the arm and the female screw or the male screw of the secondary arm. 
     In this characteristic, a groove may be disposed in the arm, and the repulsive tool may be disposed such that at least a part of the repulsive tool is fitted and held in the groove. 
     Incidentally, in this case, a mode of including a dowel-shaped protrusion or a shaft in the groove, or the like can be adopted. 
     In this characteristic, a grip portion that is different in shape and/or material from other portions of the arm may be provided at least on the one end portion side of the arm. 
     In this characteristic, a self-standing foot for holding the medicine applicator in a self-standing posture may be provided. 
     In this characteristic, the pressing tools each may include a regulating portion that regulates an operation of the repulsive tool. 
     The “regulating portion that regulates an operation of the repulsive tool” implies any portion as long as the portion can regulate the operation of the repulsive tool in a predetermined mode. For example, the regulating portion implies any one of a protrusion and recess portion that can regulate the repulsive tool so as to be slid along a predetermined trajectory (for example, a guide groove, a guide rib, or the like), a penetrated portion that can regulate the repulsive tool so as to pass through the penetrated portion within a predetermined range (for example, a passage hole, a slit, or the like), a shaft support portion that can regulate the repulsive tool so as to perform a predetermined rotation operation, and the like. Further, for example, among the specific modes of the regulating portion, the guide groove, the guide rib, the passage hole, the slit, and the like can also be paraphrased as a guide portion that guides the repulsive tool, namely, a guide portion that can guide the relative movement of the repulsive tool with respect to the pressing tools in a predetermined mode. 
     In addition, according to the invention, there is provided a medicine application kit including: the medicine applicator; and an application member disposed on the pedestal portion. 
     In addition, according to the invention, there is provided a pressing tool for medicine applicator that attachably and detachably holds an application member on the medicine applicator, the tool including: a shaft support portion swingably supported by the medicine applicator; a contact portion extending from the shaft support portion to come into contact with the application member; and a knob portion that extends from the shaft support portion in a direction different from a direction of the contact portion, to be used for gripping. 
     In this characteristic, the pressing tool for a medicine applicator may include a through-hole into which at least a part of the medicine applicator is insertable. 
     In this characteristic, the contact portion may include a non-slip portion including a protruding portion and/or a recessed portion. 
     Effect of the Invention 
     According to the invention, since the pressing tools (clamping means or the like) that are represented by clips and can attachably and detachably hold the application member (or the treatment article) are provided on the arm including the pedestal portion that is integrally formed with the arm, the application member can be easily attached and detached with a simple configuration. In addition, since the application member (or the treatment article) is simply held by the pressing tools (clamping means or the like) represented by clips, a reduction in the effective area of the application member (or the treatment article) used for applying a medicine or the like can be suppressed.

     MODES FOR CARRYING OUT THE INVENTION 
     Hereinbelow, one embodiment of a medicine applicator according to the invention will be described with reference to the drawings.  FIG.  1 ( a )  is an exploded perspective view of one embodiment of a medicine applicator  100  according to the invention,  FIG.  1 ( b )  is a partial top view of the medicine applicator  100  illustrated in  FIG.  1 ( a )  and  FIG.  1 ( c )  is a partial side view of the medicine applicator  100  illustrated  FIG.  1 ( a ) . 
     The medicine applicator  100  includes an arm  10  extending in a longitudinal direction, of which one end portion side is used for gripping; and a pedestal portion  222  disposed on the arm  10  to be substantially parallel to the longitudinal direction of the arm  10 . The medicine applicator  100  is provided with a pair of pressing tools  130  that attachably and detachably hold an application member  300  on the pedestal portion  222 , and the pair of pressing tools  130  include a repulsive tool  292  that generates a pressing force to bring the application member  300  into contact with the pedestal portion  222 . 
     The medicine applicator  100  includes an applicator body  200  including the arm  10  having a rod shape extending to approximately 30 to 70 cm, desirably, approximately 40 to 60 cm long, and the pedestal portion  222  disposed on the arm  10  to be substantially parallel to the longitudinal direction of the arm  10 . For example, when both the arm  10  and the pedestal portion  222  are made of synthetic resin, the applicator body  200  can be integrally formed by die forming, injection forming, or the like. For example, when the arm  10  is made of wood, lightweight metal such as aluminum, or the like, the pedestal portion  222  may be fixed to and integrated with the arm  10  made of wood, lightweight metal, or the like, with screws or the like. In addition, for example, the pedestal portion  222  may be fixed to and integrated with the arm  10  made of synthetic resin, with screws or the like. In addition, the pedestal portion  222  may be connected to and integrated with the arm  10  through a connecting material (not illustrated) such as a spacer. Further, in addition to a mode in which the arm  10  and the pedestal portion  222  are integrated, it is also possible to adopt a mode in which the arm  10  and the pedestal portion  222  are configured to be attachable and detachable by joining using screws or the like as in the above-described example and the size of the pedestal portion  222  can be changed, or a mode in which the cleaning of very small parts is facilitated. Incidentally, a portion at which the arm  10  and the pedestal portion  222  are joined or integrated forms a centralization portion  220  including a columnar body portion forming a part of the arm  10  in an axial direction, and the pedestal portion  222 . More specifically, the centralization portion  220  is a portion of the arm  10  including the pressing tools (clips)  130 , an attachment shaft (holding shaft)  268  of the pressing tools (clips)  130 , the pedestal portion  222 , a repulsive tool, and a repulsive tool-holding portion (including holding means such as the attachment shaft  268 ). 
     A grip portion  11  that a person to be applied grips by himself or herself is formed on the one end portion side of the arm  10 . A length of the grip portion is approximately 10 cm to 25 cm or approximately 10 cm to 18 cm. In the medicine applicator  100  of the present embodiment, since a structure is adopted in which a scratching portion of a backscratcher is replaced with the applicator body  200 , the arm  10  is slightly curved for convenience of the application of a medicine to the back of the person to be applied. However, the arm  10  may have a shape that is curved not only in one direction but also in a plurality of directions (for example, a shape that is curved in a substantially S shape, or the like) or, for example, may extend linearly. 
     A side of the arm  10  of the applicator body  200  opposite the grip portion  11  is an extending portion  14  that extends outward from the pedestal portion  222  not to affect an operation of the pedestal portion  222 . Typically, the extending portion  14  is approximately 1 cm to 5 cm long, but as in an embodiment to be described later, when the medicine applicator  100  is gripped with both hands, the extending portion  14  is replaced with an assist arm  400  extending approximately 30 cm to 70 cm (or approximately 10 to 50 cm), and a second grip portion  11  is disposed (formed) at an end portion of the assist arm  400 . The extending portion  14  may or may not penetrate through a through-hole  134  of the pressing tool  130  to be described later. 
     In order to reliably hold the application member  300  on the pedestal portion  222 , additionally, the pair of pressing tools  130  each having a substantially rectangular outer shape (laterally sectional shape of the pressing tools  130  may be an arch shape that easily fits the shape of fingers, a substantially S shape, or a crank shape) are swingably and substantially symmetrically provided on the applicator body  200  in an axial direction of the centralization portion  220  and in the vicinity of front and rear positions of the pedestal portion  222 . A configuration of the pressing tools  130  is also illustrated in  FIGS.  2 ( a ) to  2 ( d ) .  FIGS.  2 ( a ) to  2 ( c )  are a top view, a side view, and a front view of the pressing tool  130 , respectively, and  FIG.  2 ( d )  is a side view describing an operation of the pressing tool  130 . The pressing tool  130  is formed in a substantially oblong plate shape that is slightly long in one direction (up-down direction in  FIGS.  2 ( b ) to  2 ( d ) ). The through-hole  134  having a substantially oval shape that is slightly long along a length direction of the pressing tool  130  opens on a front surface of the pressing tool  130  at a position that is offset to one end of the pressing tool  130  in the length direction (lower end in  FIGS.  2 ( b ) to  2 ( d ) ) and that is at a substantially center in a width direction, and prevents the pressing tool  130  from interfering with the extending portion  14 , the centralization portion  220 , or the arm  10  when the pressing tool  130  is attached in the vicinity of the pedestal portion  222  of the applicator body  200 . Namely, the pressing tool  130  has the through-hole  134  through which at least a part of the medicine applicator  100  can penetrate. 
     A hole  137  extending in the width direction to penetrate through the pressing tool  130  from the vicinity of a central portion of the through-hole  134  of the pressing tool  130  in the length direction to both long side portions of the pressing tool  130  is provided for attaching the pressing tool  130  to the centralization portion  220 . The hole  137  is fitted to the attachment shaft  268  inserted into an attachment hole  265  of the centralization portion  220  to be described later. When viewed from the side, in the pressing tool  130 , when an imaginary line A 1  extending from a center point of the hole  137  toward the front surface of the pressing tool  130  to perpendicularly intersect the pressing tool  130  is regarded as a cutting line as illustrated in  FIG.  2 ( b ) , a knob portion  138  is formed on a counter pedestal portion  222  side (upper side in the drawing) S 2  opposite a pedestal portion  222  side (lower side in the drawing) S 1  with respect to the imaginary line A 1 , and a contact portion  132  in which a tip portion is bent in a direction of the pedestal portion  222  is formed on the pedestal portion  222  side S 1 . Namely, the pressing tool  130  is a pressing tool for a medicine applicator that attachably and detachably holds the application member  300  on the medicine applicator  100 , and that includes the hole  137  that is a shaft support portion swingably supported by the medicine applicator  100 ; the contact portion  132  extending from the shaft support portion to be able to come into contact with the application member  300 ; and the knob portion  138  that extends from the shaft support portion in a direction different from a direction of the contact portion  132 , to be used for gripping. 
     As illustrated in  FIGS.  1 ( a ) and  2 ( a ) , a guide rail  160  having a groove shape with a substantially semi-circular cross-section and extending linearly from the vicinity of the through-hole  134  toward the other end of the pressing tool  130  in the length direction (upper end in  FIG.  1 ( a ) ) is formed in a back surface (pedestal portion  222 -side surface) of the pressing tool  130 . Namely, in one side surface of the pressing tool  130 , toward which the tip portion of the contact portion  132  is bent, the guide rail  160  having a groove shape with a substantially arc-shaped cross section is provided in the pressing tool  130  to extend linearly from a substantially center of a short side forming the other end of the pressing tool  130  in the length direction (upper end in  FIG.  1 ( a ) ) to a position in the vicinity of one end of the through-hole  134  in the length direction (upper end in  FIG.  1 ( a ) ) along the length direction of the pressing tool  130  (up-down direction in  FIG.  1 ( a ) ). The guide rail  160  is formed with a width and depth such that a bent portion  2921  of the repulsive tool (kick spring)  292  to be described later can be fitted into the guide rail  160  with a slight margin (play). It is desirable that at least a surface (inner surface) of the guide rail  160  has, for example, a good sliding characteristic (low coefficient of friction, high wear resistance, or the like). For this reason, for example, at least the surface (inner surface) of the guide rail  160  may be made of resin such as polyacetal, polyamide, or polytetrafluoroethylene (PTFE) or other materials having a good sliding characteristic, or depending on the material of the pressing tool  130 , a surface layer made of a material having a good sliding characteristic, as described above may be provided on the surface (inner surface) of the guide rail  160 . In addition, in the embodiment, a mode is adopted in which the guide rail is required, but the invention also corresponds to a mode in which the guide rail is not used. 
     A pair of the attachment holes  265  that are substantially symmetrically disposed in the axial direction in a side surface of the centralization portion  220  of the applicator body  200  (a pair in one side surface of both right and left side surfaces) are disposed in both the right and left side surfaces, and the attachment shafts  268  are inserted and attached to the respective attachment holes  265 . The attachment shafts  268  are fitted to the respective holes  137 , and the pressing tools  130  are swingably attached to the centralization portion  220 . As illustrated in  FIG.  1 ( c ) , end portions (both end portions) of the repulsive tool (kick spring)  292  are bent inward (coil side) in a hook shape, so that the bent portions  2921  each having a shape that is locally bent in a curved shape are formed, and the bent portions  2921  may press back surface sides of the knob portions  138  of the respective pressing tools  130  or may extend in a shape where the end portions of the repulsive tool are processed not to cause resistance between the end portions of the repulsive tool and the pressing tools when the pressing tools are operated, for example, linearly or in an arc shape, or tips of the repulsive tool  292  may be processed into a substantially spherical shape or the like. At this time, the bent portions  2921  of the repulsive tool (kick spring)  292  are fitted into the respective guide rails  160  and press the back surface sides of the knob portions  138  of the respective pressing tools  130  while sliding in the respective guide rails  160 . Here, for example, if the pressing tools each are not provided with a portion such as the guide rail, the repulsive tool is offset (deviates) with respect to the pressing tools in a direction other than a desired direction, and as a result, a pressing force of the repulsive tool cannot be sufficiently transmitted to the pressing tools. On the other hand, according to a configuration in which an operation of the repulsive tool (kick spring)  292  is regulated by the guide rails  160  (regulating portions) as in the present embodiment, the operation of the repulsive tool can be more reliably and easily performed, and accordingly, a pressing force of the repulsive tool can be reliably and sufficiently transmitted to the pressing tools. In addition, particularly, since the bent portions  2921  each have a shape that is locally bent in a curved shape as in the above-described example, and slide in the respective guide rails  160  on outer sides of the bent portions  2921 , the bent portions  2921  can more smoothly slide. The attachment shafts  268  are attached and fixed to the respective attachment holes  265 , but the attachment shafts  268  may be rotatably fitted to the respective attachment holes  265 , and the attachment shafts  268  may be fixed to the holes  137  of the respective pressing tools  130  through welding, caulking, brazing, bonding, or the like. 
     A groove  232  having various shapes such as a substantially semi-circular shape in a side view, a quadrilateral shape, an oblong shape, and an elliptical shape in a top view, and a circular column shape in a perspective view is disposed in the axial direction of an upper peripheral surface of the centralization portion  220  (length direction of the arm  10 ), a hole  235  passing through the groove  232  in a radial direction is provided in the centralization portion  220 , and a presser pin  234  is provided across the groove  232  using the hole  235 . The presser pin  234  may be configured to be inserted into the hole  235  and to be fixed by a frictional force, or an end portion of the presser pin  234  after being fitted may be subjected to a process of preventing fall out, such as caulking. In addition, a long screw with a head may be used as the presser pin  234  and combined with one side of the through-hole  235  using a nut. A coil portion of the repulsive tool (kick spring)  292  is wound around the presser pin  234  (refer to  FIGS.  1 ( b ) and  1 ( c ) ), in other words, the repulsive tool (kick spring)  292  is disposed such that at least a part of the repulsive tool (kick spring)  292  is fitted and held in the groove  232 , so that the repulsive tool (kick spring)  292  that is disposed in a pre-biased state to press the back surface sides of the knob portions  138  of the pressing tools  130  can be reliably held by the centralization portion  220 . 
     An action of the repulsive tool (kick spring)  292  that is pre-biased and attached, and an operation of the pressing tools caused by the action will be described in detail with reference to  FIG.  1 ( c ) .  FIG.  1 ( c )  illustrates a state where the repulsive tool (kick spring)  292  that is a spring as a repulsive tool for pressing tools and one (right in the drawing) pressing tool  130  are attached and the other (left in the drawing) pressing tool  130  is removed. A portion of the repulsive tool (kick spring)  292  that is formed in a coil shape is wound around the presser pin  234 , is held by the centralization portion  220 , and is restricted in movement. The bent portion  2921  of the repulsive tool (kick spring)  292  is slidably fitted into the guide rail  160  of the pressing tool  130  without being fixed, and the back surface side of the knob portion  138  of the pressing tool  130  that is swingably held by the centralization portion  220  is pressed by an elastic force (restoring force) of the repulsive tool (kick spring)  292 . As illustrated in  FIG.  2 ( d ) , the pressing tool  130  pressed by the elastic force rotates around the attachment shaft  268  (hole  137 ) based on the principle of leverage, and the contact portion  132  that is a counter knob portion  138  side comes into contact with and is pressed against the pedestal portion  222  through (or without intervention of) the application member  300 , so that the rotational movement of the pressing tool  130  is stopped. The elastic force (restoring force) of the repulsive tool (kick spring)  292  that is pre-biased and attached continues to act under the above-described conditions unless any one of the components is deformed or damaged, and is maintained without being released. The elastic force (restoring force) of the repulsive tool (kick spring)  292  acts as a force (rotational moment) that presses the back surface side of the knob portion  138  of the pressing tool  130  to rotate the pressing tool  130 . 
     The knob portions  138  and  138  of the pressing tools  130  that are substantially symmetrically provided with back surfaces facing each other are rotated and separated from each other by the elastic force (restoring force) of the repulsive tool (kick spring)  292 . Accordingly, the contact portions  132  that are lower portions below swing centers (holes  137 ) of the respective rotating pressing tools  130  approach each other and abut on the pedestal portion  222  through (or without intervention of) the application member  300 . The application member  300  attached to the side surface and a bottom surface of the pedestal portion  222  is pressed against the pedestal portion  222  and is clamped by the contact portions  132 . This state is a state where the application member  300  is held by the applicator body  200 . In order to attach and detach the applicator body  200  and the application member  300  to and from each other, a force against the elastic force (restoring force) of the repulsive tool (kick spring)  292  is applied to the repulsive tool (kick spring)  292  through the knob portions  138 . Namely, the knob portions  138  of the pair of pressing tools  130  are pinched by the fingers to approach each other, and the pressing tools  130  are swung. The knob portions  138  are pinched by the fingers with a force stronger than the elastic force (restoring force) of the repulsive tool (kick spring)  292 , so that the knob portions  138  rotate around the respective attachment shafts  268  (holes  137 ) to approach each other. Accordingly, each of the contact portions  132  and  132  that are the lower portions below swing center axes (holes  137 ) of the respective rotating pressing tools  130  separates from the pedestal portion  222  to generate a space for attaching and detaching the application member  300 . This state is a state where the application member  300  is released from the applicator body  200 . 
     The application member  300  is disposed on a bottom surface side of the pedestal portion  222 . More specifically, as illustrated in  FIG.  2 ( d ) , the application member  300  is held by being disposed to cover a bottom surface portion of the pedestal portion  222  and to wrap around side surface portions and by being pressed against both surface portions of the pedestal portion  222  and clamped by the contact portions  132  of the pair of pressing tools  130  from both sides. However, as the disposition of the application member  300 , a mode other than such a mode can also be adopted. For example, a mode may be adopted in which the application member  300  covers a part of the bottom surface portion of the pedestal portion  222  instead of covering the entirety thereof. In other words, as the disposition of the application member  300 , a mode can be adopted in which the application member  300  covers the entirety or a part (at least a part) of the bottom surface portion of the pedestal portion  222 . In addition, for example, a mode can also be adopted in which the application member is disposed to cover only (at least a part of) the bottom surface portion without reaching the side surface portions of the pedestal portion and a peripheral edge portion of the application member is pressed against the bottom surface portion of the pedestal portion and is held by the contact portions of the pressing tools (not illustrated). In the case of this mode, for example, when the pressing tools are formed in a shape in which tip portions of the pressing tools are bent further inward (knob portion side), the bottom surface portion of the pedestal portion can be pressed by the tip portions. 
     As the application member  300 , any one of cotton puff, cut cotton, paper, or fabric which is soaked with a medicine or to which a paste-like medicine is applied can also be used. Since the size of the cotton puff that is commercially available is 60×80, 58×70, 50×60, 55×70, 50×65, or the like (dimensional unit is mm), namely, has a short side of approximately 50 to 60 mm and a long side of approximately 60 to 80 mm, and the size of the cut cotton is 40×40, 50×60, 50×50, 50×70, 56×80, 70×70, or the like (dimensional unit is mm), namely, has a short side of approximately 40 to 70 mm and a long side of approximately 40 to 80 mm, the size of the pedestal portion  222 , namely, the dimensions of sides of the bottom surface may be approximately equal to or less than the dimensions of sides of the application member  300 . Specifically, a length of the short side (axial direction of the arm  10 ) is approximately 30 to 60 mm, and a length of the long side (radial direction of the arm  10 ) is approximately 30 to 80 mm. However, since the application member that is commercially available is generally expandable and contractable, the dimensions of the sides of the bottom surface of the pedestal portion  222  may be larger than the above-described values. 
     Incidentally, the medicine applicator  100 , and the application member  300  disposed on the pedestal portion  222  can form a medicine application kit. 
     Next,  FIGS.  3 ( a ) to  4 ( e )  illustrate modification examples of the repulsive tool used for the pressing tools  130  according to the invention. 
     Incidentally, in each modification example provided below, the same members or portions as those of the embodiment illustrated in  FIGS.  1 ( a ) to  1 ( c )  are denoted by the same letter or numerals, and basically, a description thereof will not be repeated unless otherwise necessary. 
       FIGS.  3 ( a ) and  3 ( b )  illustrate modification examples in which the repulsive tool that is a kick spring is changed to repulsive tools (leaf springs)  294  and  296 .  FIG.  3 ( a )  is an example in which the repulsive tool (leaf spring)  294  disposed to protrude upward is used, and  FIG.  3 ( b )  is an example in which the repulsive tool (leaf spring)  296  disposed to protrude downward is used as a repulsive tool. In the modification example illustrated in  FIG.  3 ( b ) , a clearance hole  161  is formed in a portion of the centralization portion  220  of the arm  10  immediately below the repulsive tool (leaf spring)  296  such that the portion does not interfere with the repulsive tool (leaf spring)  296 . In the present modification example, the repulsive tool is fixed only to the pressing tools  130  without being held by the centralization portion  220 . Specifically, the repulsive tool can be configured simply by fixing both end portions of the repulsive tool (leaf spring)  294  or  296  to the back surface sides of the knob portions  138  of the pair of respective pressing tools  130  in a pre-biased state without holding the repulsive tool on the centralization portion  220 . Namely, both the end portions of the repulsive tool (leaf spring)  294  or  296  are fixed to the back surface sides of the knob portions  138  and  138  of the respective pressing tools  130  that are substantially symmetrically disposed with the back surfaces facing each other. The pressing tools  130  are rotated by an elastic force (restoring force) of the repulsive tool (leaf spring)  294  or  296 , and the knob portions  138  and  138  of the pressing tools  130  are separated from each other. 
     Incidentally, in the modification example illustrated in  FIG.  3 ( b ) , the clearance hole  161  is formed as described above, but for example, the repulsive tool (leaf spring) disposed to protrude downward may be provided to avoid the centralization portion of the arm (in a positional relationship illustrated in  FIG.  3 ( b ) , the repulsive tool (leaf spring) is disposed at the position of both end portions of the pressing tools  130  in the width direction, namely, the position of front and rear end portions of the pressing tools  130  in the drawing to be laterally offset from the centralization portion  220 ), and according to this configuration, the clearance hole can be eliminated. 
     As a specific example of attaching the repulsive tool (leaf spring)  294  or  296  to the knob portions  138 , when the knob portions  138  and the repulsive tool (leaf spring)  294  or  296  are made of materials that can be melted into each other, the knob portions  138  and the repulsive tool (leaf spring)  294  or  296  can be attached to each other by welding, bonding, or the like. When the knob portions  138  and the repulsive tool (leaf spring)  294  or  296  are made of materials that cannot be melted into each other, the knob portions  138  and the repulsive tool (leaf spring)  294  or  296  can be attached to each other by tightening, tacking, bonding, or the like using an adhesive agent, riveting, screwing, brazing, or the like. Alternatively, when holders into which the end portions of the repulsive tool (leaf spring)  294  or  296  can be fitted are disposed on the back surface sides of the respective knob portions  138 , and the end portions of the repulsive tool (leaf spring)  294  or  296  are inserted into the respective holders, the end portions of the repulsive tool (leaf spring)  294  or  296  can be reliably fixed to the respective knob portions  138 . Incidentally, the repulsive tool (leaf spring)  294  or  296  may be reliably fixed to the holders by additionally riveting or brazing the fitted portions. An action of the elastic force (restoring force) of the repulsive tool applied to the pressing tools, and an operation of the pressing tools caused by the action are the same as the contents illustrated in  FIGS.  1 ( a ) to  2 ( d ) . 
     Incidentally, both the end portions of the repulsive tool (leaf spring)  294  or  296  may be fixed to the respective pressing tools  130  as described above, but in addition to this mode, for example, both the end portions of the repulsive tool may be supported by shafts extending along a width direction of the leaf spring (or the width direction of the pressing tools), and rotatably attached to the respective pressing tools, and according to this configuration, the pressing tools can be more smoothly operated. 
       FIGS.  4 ( a ) to  4 ( e )  illustrate an example in which the attachment position and the shape of the repulsive tool (kick spring)  292  are changed, and an example in which the repulsive tool is changed to a leaf spring,  FIG.  4 ( a )  is a top view of the applicator body  200  including the repulsive tool (kick spring)  292 ,  FIG.  4 ( b )  is a front view of the applicator body  200 ,  FIG.  4 ( c )  is a side view of the applicator body  200 ,  FIG.  4 ( d )  is a front view of the applicator body  200  including a repulsive tool (leaf spring)  292   a,  and  FIG.  4 ( e )  is a side view thereof. In order to clearly illustrate the repulsive tool (kick spring)  292  and the repulsive tool (leaf spring)  292   a,  in these drawings, the pressing tools  130  are omitted (except that one is illustrated by a broken line in  FIGS.  4 ( c ) and  4 ( e ) ). 
     Specifically, two flake-shaped holding portions  284  and  284  are integrally formed on the upper peripheral surface of the centralization portion  220  of the applicator body  200  to stand in a posture parallel to the length direction of the arm  10  with surfaces of the holding portions  284  and  284  being spaced from and facing each other. A hole is formed in each of the holding portions  284 , and a shaft  290  is inserted and fixed to the holes. The coil portion of the repulsive tool (kick spring)  292  is wound around the shaft  290 , and the repulsive tool (kick spring)  292  is disposed in a pre-biased state. The bent portions  2921  are formed at both the end portions of the repulsive tool (kick spring)  292 , and the bent portion  2921  presses the back surface side of the knob portion  138  of the pressing tool  130  while being fitted and sliding in the guide rail  160  (not illustrated in  FIGS.  4 ( a ) to  4 ( e ) ) of the pressing tool  130  illustrated by broken line. On the other hand, similarly to the embodiment illustrated in  FIGS.  1 ( a ) to  1 ( c ) , the pressing tool  130  is swingably held by the attachment shaft  268  inserted into the attachment holes  265  disposed in the respective right and left side surfaces of the centralization portion  220 . Also in the present modification example, similarly to the embodiment illustrated in  FIGS.  1 ( a ) to  1 ( c ) , the pressing tools  130  reliably clamp the application member  300  attached to the pedestal portion  222 , so as to be attachable and detachable. An action between the pressing tools (clips or the like) and the repulsive tool that is the repulsive tool (kick spring)  292  that presses the back surface sides of the knobs  138  of the pressing tools  130 , and an operation of the pressing tools caused by the action are the same as those of the embodiment and the modification examples. 
     In the modification example illustrated in  FIGS.  4 ( d ) and  4 ( e ) , similarly to  FIGS.  4 ( a ) to  4 ( c ) , the holding portions  284  of the repulsive tool are formed, but since the repulsive tool is a leaf spring, the coil portion of the repulsive tool (kick spring) is not wound around the shaft  290 , and the repulsive tool (leaf spring)  292   a  that is a repulsive tool simply passes between the upper peripheral surface of the centralization portion  220  of the applicator body  200  and the shaft  290 . The repulsive tool (leaf spring)  292   a  passes between the upper peripheral surface of the centralization portion  220  of the applicator body  200  and the shaft  290  to extend in the axial direction of the centralization portion  220 , and is disposed in a pre-biased state to press the back surface side of the knob portion  138  of the pressing tool  130 . A guide rail having a groove shape and having a width and a depth corresponding to the width and the thickness of the repulsive tool (leaf spring)  292   a  is formed on the back surface side of the knob portion  138  of the pressing tool  130  to extend up and down (not illustrated), and a bent portion  2921   a  of the repulsive tool (leaf spring)  292   a  is fitted and slides in the guide rail. In order to prevent separation from the applicator body  200  caused by frictional movement, the repulsive tool (leaf spring)  292   a  may be processed into a bent shape in the vicinity of the shaft  290 . An action between the pressing tools and the repulsive tool that is the repulsive tool (leaf spring)  292   a  that presses the back surface sides of the knob portions  138  of the pressing tools  130 , and an operation of the pressing tools caused by the action are the same as those of the embodiment and the modification examples. 
       FIGS.  5 ( a ) and  5 ( b )  are a modification example in which the holding portions  284  are omitted in the modification example of  FIGS.  4 ( d ) and  4 ( e ) . A fastening hole is formed at a substantially center of a repulsive tool (leaf spring)  292   b.  The fastening hole or a fastening shaft is disposed in the upper peripheral surface of the centralization portion  220 , and a fastener  293  fixes the repulsive tool (leaf spring)  292   b  to the centralization portion  220  using the hole provided in the repulsive tool (leaf spring)  292   b.  The repulsive tool (leaf spring)  292   b  is formed with a length that presses the back surface sides of the knob portions  138  of the pair of pressing tools  130 , extends from a listening hole portion in the axial direction of the centralization portion  220 , and is disposed in a pre-biased state to press the back surface sides of the knob portions  138  of the pressing tools  130  while the bent portions  2921   a  are fitted and slid in guide rails (not illustrated). An action between the pressing tools and the repulsive tool that is the repulsive tool (leaf spring)  292   b  that presses the back surface sides of the knob portions  138  of the pressing tools  130 , and an operation of the pressing tools  130  caused by the action are the same as those of the embodiment and the modification examples. 
       FIGS.  6 ( a ) and  6 ( b )  illustrate another modification example in which the repulsive tool is held by the centralization portion  220  of the applicator body  200 .  FIGS.  6 ( a ) and  6 ( b )  are a top view and a side view, respectively, when the repulsive tool (leaf spring)  292   a  is used as a repulsive tool. 
     Similarly to the embodiment illustrated in  FIGS.  1 ( a ) to  1 ( c ) , the groove  232  is formed. Namely, the groove  232  having a substantially semi-circular shape is disposed in the axial direction of the upper peripheral surface of the centralization portion  220  (length direction of the arm  10 ), the hole  235  passing through the groove  232  in the radial direction is provided in the centralization portion  220  at the position of a substantially center of the groove, and the presser pin  234  is provided across the groove  232  using the hole  235 . The repulsive tool (leaf spring)  292   a  passes between the presser pin  234  and a bottom surface of the groove  232 , in other words, the repulsive tool (leaf spring)  292   a  is disposed such that at least a part of the repulsive tool (leaf spring)  292   a  is fitted and held in the groove  232 , so that the repulsive tool (leaf spring  292   a  disposed in a pre-biased state to press the back surface sides of the knob portions  138  of the pressing tools  130  can be reliably held by the centralization portion  220 . An action between the pressing tools and the repulsive tool that is the repulsive tool (leaf spring)  292   a  that presses the back surface sides of the knob portions  138  of the pressing tools  130 , and an operation of the pressing tools caused by the action are the same as those of the embodiment and the modification examples. The end portions of each of the leaf springs of  FIGS.  4 ( d ) and  4 ( e ) ,  FIGS.  5 ( a ) and  5 ( b ) , and  FIGS.  6 ( a ) and  6 ( b )  that are the embodiment may be fixed to or held by the back surface sides of the knob portions  138  of the respective pressing tools  130  as in the modification example of  FIGS.  3 ( a ) and  3 ( b ) . 
     (Other Modification Examples) 
     (1) 
     Next,  FIG.  7    illustrates a modification example of the medicine applicator  100  according to the invention. In the present modification example, the configuration of the arm  10  is changed, and any applicator body  200  illustrated in the embodiment and in the examples can also be applied.  FIG.  7    is a side cross-sectional view of a medicine applicator. In the embodiment and each modification example, the extending portion  14  that is relatively short is provided at a counter grip portion-side end portion of the applicator body  200 , but the assist arm  400  including a grip portion (not illustrated) is added in the axial direction of the arm  10 . Namely, the assist arm  400  and the arm  10  form a medicine applicator  102 , so that a user can grip the grip portions  11  provided at both end portions of the assist arm  400  and the arm  10 , and move the applicator body  200  on the skin in a dry fabric rubbing manner. Accordingly, the operability of the applicator body  200  is improved. For this reason, the configuration is such that the pedestal portion  222  is disposed at the other end portion (counter grip portion-side end portion) of the arm  10  or in the vicinity thereof, a male screw  412  is formed at the counter grip portion-side end portion of the arm  10 , and a female screw  414  is formed at an end portion of the assist arm  400 , and the medicine applicator  102  of a double grip type can be configured by attachably and detachably attaching the assist arm  400  to the arm  10  through screwing of the male screw  412  and the female screw  414 . According to the present modification example, the medicine applicator  102  can be gripped and used with both hands. In addition, needless to say, in the medicine applicator  102  according to the present modification example, the assist arm  400  and the arm  10  are disassembled, and the arm  10  in a state where the assist arm  400  is not added can also be used in the same manner as the mode illustrated in  FIGS.  1 ( a ) to  1 ( c ) . In addition, the disposition of the male screw  412  and the female screw  414  may be replaced such that the above-described disposition is reversed (namely, a female screw and a female screw are disposed at the counter grip portion-side end portion of the arm  10  and at the end portion of the assist arm  400 , respectively). 
     (2) 
     A joint structure between the arm and the assist arm is not limited to the above-described screwing between the male screw (or the female screw) provided in the arm and the female screw (or the male screw) provided in the assist arm. For example, as illustrated in  FIGS.  8 ( a ) to  8 ( c ) , a structure may be adopted in which a mortise portion  514  and a screw hole  514   a  penetrating through a side wall portion of the mortise portion  514  in the radial direction are formed at an end portion of an assist arm  500 , a tenon portion corresponding to the mortise portion  514  is formed at the counter grip portion-side end portion of the arm (not illustrated), and the tenon portion is inserted into the mortise portion  514  and a screw  514   b  is screwed into the screw hole  514   a  from the outside to join the assist arm  500  to the arm.

     Further, for example, as illustrated in  FIGS.  9  to  11   , a structure may be adopted in which in addition to a tenon portion and a mortise portion, a secondary mortise portion and a secondary tenon portion are formed. In a joint structure illustrated in the same drawings, a tenon portion  612  is formed at a counter grip portion-side end portion of an arm  610 , and a mortise portion  614  is formed at an end portion of an assist arm  600 . 
     As illustrated in  FIG.  10   , the tenon portion  612  has a diameter that is one size smaller than a diameter of the arm  610 , and extends in a circular column shape from the counter grip portion-side end of the arm  610  in the axial direction. A secondary mortise portion  612   a  is formed inside the tenon portion  612 , the secondary mortise portion  612   a  having an inner diameter that is one size much smaller than that diameter of the tenon portion  612 , and extending in a circular hole shape over a substantially total length of the tenon portion  612  in the axial direction. In addition, a groove portion  612   b  recessed from a surface of the tenon portion  612  to have an arc cross-sectional shape is formed at the position of a substantially center of the tenon portion  612  in the axial direction to extend along a circumferential direction. 
     As illustrated in  FIG.  11   , the mortise portion  614  is formed at the end portion of the assist arm  600  to have an inner diameter and a depth corresponding to the tenon portion  612  and to be recessed in a circular hole shape, and similarly to the above-described modification example illustrated in  FIGS.  8 ( a ) to  8 ( c ) , a screw hole (not illustrated) penetrating through a side wall portion of the mortise portion  614  in the radial direction is formed. In addition, a secondary tenon portion  614   a  having a diameter and a length corresponding to the secondary mortise portion  612   a  and extending in a circular column shape in the axial direction is formed on a central portion of an inmost surface of the mortise portion  614 . 
     The assist arm  600  can be joined to the arm  610  by inserting the tenon portion  612  into the mortise portion  614  and by screwing a screw  614   b  into the screw hole from the outside as illustrated in  FIG.  9   . According to this joint structure, the secondary mortise portion  612   a  and the secondary tenon portion  614   a  enable more reliable and stable joining. 
     (4) 
     Further, for example, as schematically illustrated in  FIG.  12   , a configuration may be adopted in which a pedestal portion  722  is disposed on a substantially central portion of an arm  710  and both end portions of the arm  710  are used for gripping. Similarly to the medicine applicator  100  according to the embodiment illustrated in  FIG.  1   , a medicine applicator  700  illustrated in the same drawing includes the arm  710  having a rod shape and extending long; the pedestal portion  722  disposed on the arm  710 ; and pressing tools  713  and  713 , but whereas the arm  10  according to the embodiment illustrated in  FIGS.  1 ( a ) to  1 ( c )  has a length of approximately 30 to 70 cm (or approximately 40 to 60 cm), the arm  710  according to the present modification example has a total length of approximately 60 to 140 cm (or approximately 40 to 110 cm) that is longer by a length of approximately 30 to 70 cm (or approximately 10 to 50 cm) of the assist arm. In other words, the arm  710  according to the present modification example has a non-divided configuration having, for example, a total length of approximately 60 to 140 cm that is substantially equivalent to a length obtained by adding, for example, a length of approximately 30 to 70 cm of the assist arm  400  according to the modification example illustrated in  FIG.  7    to, for example, a length of approximately 30 to 70 cm of the arm  10  according to the embodiment illustrated in  FIGS.  1 ( a ) to  1 ( c ) , namely, a configuration in which the arm and the assist arm are not divided and integrally formed from the beginning. 
     Then, the configuration is such that the pedestal portion  722  is disposed on the substantially central portion of the arm  710  according to the present modification example and both the end portions of the arm  710  are used for gripping as grip portions  711  and  711 . 
     In the medicine applicator  700  according to the present modification example, a user can grip the grip portions  711  and  711  formed at both the end portions, and move an applicator body on the skin in a dry fabric rubbing manner. Accordingly, similarly to the case of the medicine applicator  102  according to the modification example illustrated in  FIG.  7   , the operability of the applicator body is improved. 
     Incidentally, a configuration of a pressing mechanism (repulsive tool and the like) of  FIGS.  7 ,  9 , and  12    that are modification examples conforms to that of  FIGS.  1 ( a ) to  6 ( b ) . 
     (5) 
     Next,  FIGS.  13 ( a ) and  13 ( b )  illustrate a further modification example of the medicine applicator  100  according to the invention. A medicine applicator  900 B according to the present modification example is configured such that a grip portion having a shape different from that of other portions of an arm is provided on at least one end portion side of the arm. 
     The grip portion may be, for example, a grip portion having substantially the same configuration as that of other portions of the arm similarly to the grip portion  11  of the medicine applicator  100  according to the embodiment illustrated in  FIGS.  1 ( a ) to  1 ( c ) , but may be a grip portion having a configuration different from that of other portions of the arm as in the medicine applicator  900 B according to the present modification example, so that the ease to grip, the handleability, or the like can be further improved. 
     In the medicine applicator  900 B according to the modification example illustrated in  FIGS.  13 ( a ) and  13 ( b ) , one end portion side of an arm  910 B having a round rod shape with a circular cross section is formed in a flat plate shape by being crushed from both sides in the radial direction (both upper and lower sides in  FIGS.  13 ( a ) and  13 ( b ) ) to the center, to form a grip portion  911 B. Both end edge portions of the grip portion  911 B are formed with an arc-shaped cross section (substantially semi-circular shape). 
     According to the grip portion  911 B described above, since a grip position is unlikely to be offset in the circumferential direction when the grip portion  911 B is gripped with a hand, more reliable gripping is possible, and particularly, even when the person to be applied performs an operation on the back that he or she cannot see, a posture of the medicine applicator  900 B around an axis (angular position) can be easily and reliably identified, and the medicine applicator  900 B is easily controlled and held at a desired angular position. 
     Furthermore, in addition to the grip portion  911 B described above, for example, a non-slip portion may be provided on at least one end portion side of the arm by forming a layer made of rubber or the like on a surface portion or by forming protrusions and recesses in a surface, to form the grip portion. Namely, the grip portion may be different in shape and/or material from other portions of the arm. In addition, various grip portions provided as exemplary examples above can also be provided on the other end portion side of the arm or in the assist arm. 
     (6) 
     The contact portion of the pressing tool can adopt various configurations. For example, as illustrated in  FIGS.  14 ( a ) to  14 ( f ) , contact portions each including a non-slip portion including a protruding portion and/or a recessed portion are exemplary examples. 
     Each of contact portions  132   a  to  132   c  illustrated in  FIGS.  14 ( a ) to  14 ( c ) , similarly to the contact portion  132  according to the embodiment illustrated in  FIGS.  1 ( a ) to  1 ( c ) , is formed by bending a tip portion in the direction of the pedestal portion, and each of contact portions  132   d  to  132   f  illustrated in  FIGS.  14 ( d ) to  14 ( f ) , is directly formed on a pedestal portion-side surface of a tip portion without the tip portion being bent. Accordingly, a portion that can come into contact with the application member is provided with various non-slip portions. 
     The contact portions  132   a  to  132   c  illustrated in  FIGS.  14 ( a ) to  14 ( c )  are formed in a shape in which the tip portions of the respective pressing tools are bent inward (pedestal portion side), to form respective projections  135   a  to  135   c  as protruding portions. More specifically, the projection  135   a  illustrated in  FIG.  14 ( a )  is shaped such that a tip edge is linear, the projection  135   b  illustrated in  FIG.  11 ( b )  is shaped such that a tip edge extends upward and downward in a wave shape, and the projection  135   c  illustrated in  FIG.  14 ( c )  is shaped such that a tip edge extends upward and downward in a mountain-and-valley shape. 
     Each of the contact portions  132   d  to  132   f  illustrated in  FIG.  14 ( d ) to  14 ( f )  is configured such that a protruding portion and/or a recessed portion are formed on the pedestal portion-side surface of the tip portion. More specifically, the contact portion  132   d  illustrated in  FIG.  14 ( d )  is subjected to embossing to form a protrusion and recess surface portion  135   d  including a large number of protrusions and recesses. The contact portion  132   e  illustrated in  FIG.  14 ( e )  is provided with a plurality of slits disposed along the width direction of the pressing tool, to form a protrusion and recess surface portion  135   e.  Incidentally, instead of the slits or in combination with the slits, a projection protruding from the pedestal portion-side surface of the tip portion may be provided. The contact portion  132   f  illustrated in  FIG.  14 ( f )  forms a protrusion and recess surface portion  135   f  having a shape that is processed to form protrusions and recesses in a grid pattern. 
     Further, in addition to the foregoing modes, for example, it is also possible to adopt a mode in which the pedestal portion-side surface of the tip portion is subjected to a surface treatment to have a sand shape (by application, etching, or the like), or a mode in which the pedestal portion-side surface of the tip portion is not subjected to a treatment. 
     (7) 
     As the arm, in addition to an arm having a round rod shape similar to the arm  10  according to the embodiment, for example, anus having various shapes such as an arm having a prismatic shape, an arm having a substantially T shape in a cross-sectional view, and an arm having a substantially H shape in a cross-sectional view can be used. In addition, the arm may be solid or hollow (pipe shape). Furthermore, the arm may have a mode in which the arm is expandable and contractable by a nested structure or the like, or a mode in which a centralization portion side and a grip portion side of the arm can be separated by a nested structure or the like. 
     According to the embodiment and each modification example of the invention described above, the person to be applied can evenly apply an antiphlogistic agent, a medicine, or a cosmetic such as a sunblock to the back that he or she cannot see. 
     (8) 
     In addition, in the embodiment and each modification example, a body portion of the centralization portion  220  and the arm  10  on a grip portion side are integrally disposed as described above, but far example, as illustrated in  FIG.  15   , the body portion of the centralization portion  220  and the arm  10  on a grip portion  11  side and on an extending portion  14  side are cut from each other along cutting planes parallel to the radial direction as illustrated by broken line A 2 , and both are coupled to each other in the axial direction to be rotatable around a coupling axis  295 . Incidentally, the arm  10  on the extending portion  14  side may remain integrated with the body portion of the centralization portion  220  without being cutting therefrom. Namely, the configuration may be such that at least the body portion of the centralization portion  220  and the arm  10  on the grip portion  11  side are cut from each other. Since the centralization portion  220  and the arm  10  on the grip portion side are configured to be rotatable (or swingable) in such a manner, as illustrated by arrow A 3 , the pedestal portion  222  is two-dimensionally rotatable in a left-right direction (in a swinging manner) with respect to the grip portion  11 , and the application member  300  can be smoothly brought into close contact with a curved surface of the skin of the person to be applied. 
     (9) 
     Next,  FIGS.  16 ( a ) to  16 ( d )  illustrate a further modification example of the medicine applicator according to the invention. A medicine applicator S 100  illustrated in the same drawing is provided with a penetrated portion as a regulating portion that can regulate a repulsive tool so as to pass through the penetrated portion within a predetermined range. 
     In the present modification example, as illustrated in  FIGS.  16 ( a ) and  16 ( b ) , a repulsive tool  162  is configured by forming a leaf spring (or a wire spring or the like) to be curved in a partially circular shape (substantially C shape) in which a part is missing. In addition, a configuration of an arm S 10  is the same as the configuration of the arm  10  according to the embodiment illustrated in  FIGS.  1 ( a ) to  1 ( c ) , except that clearance holes  165  and  165  are provided outside the attachment positions of a pair of pressing tools S 130  and S 130  (on sides opposite the pedestal portion  222  side), respectively. On the other hand, as illustrated in  FIGS.  16 ( c ) and  16 ( d ) , each of the pressing tools S 130  has the same configuration as that of the pressing tool  130  according to the embodiment illustrated in  FIGS.  1 ( a ) to  1 ( c ) , except that the guide rail is not provided and a passage hole  163  and a holding hole  164  are provided at substantially central portions in a width direction of an upper end edge-vicinity portion and a lower end edge-vicinity portion, respectively. The passage hole  163  has a substantially oblong cross-sectional shape that is laterally long and that is larger than the cross section of the repulsive tool  162 , and as illustrated in  FIG.  16 ( c ) , penetrates through the pressing tool S 130  from a back surface (pedestal portion  222 -side surface) to a front surface while being inclined downward, to form a curved shape corresponding to the shape of the repulsive tool  162 . The holding hole  164  has the same cross-sectional shape as that of the passage hole  163 , and as illustrated in  FIG.  16 ( c ) , is recessed from the front surface of the pressing tool S 130  to the vicinity of a central portion in a thickness direction while being inclined downward, to form a curved shape corresponding to the shape of the repulsive tool  162  (namely, the holding hole  164  is formed to open only on a front surface side of the pressing tool S 130  and to come to a dead end inside the pressing tool S 130  without penetrating to a back surface side). As illustrated in  FIGS.  16 ( a ) and  16 ( b ) , the clearance holes  165  each have a substantially oblong cross-sectional shape that is laterally long and that is larger than the cross section of the repulsive tool  162 , and penetrate through the arm S 10  from positions that are slightly closer to both outer sides in a length direction of the arm S 10  than the pedestal portion  222 , to an opposite side (upper side in  FIGS.  16 ( a ) to  16 ( d ) ) on a pedestal portion  222 -formation side of a peripheral surface of the arm S 10  (lower side in  FIGS.  16 ( a ) to  16 ( d ) ) while extending to both the outer sides in the length direction, to form a curved shape corresponding to the shape of the repulsive tool  162 . 
     As illustrated in  FIGS.  16 ( a ) and  16 ( b ) , similarly to the case of the embodiment illustrated in  FIGS.  1 ( a ) to  1 ( c ) , the pair of pressing tools S 130  and S 130  are attached to the arm S 10 , and the repulsive tool  162  is disposed to pass through the passage holes  163  and  163  of both the pressing tools S 130  and S 130  and through the clearance holes  165  and  165  of the arm S 10  and to be fitted into the holding holes  164  and  164  of both the pressing tools S 130  and S 130  at both ends of the repulsive tool  162 . In a disposed state, as illustrated by arrow A 4  in  FIG.  16 ( b ) , an elastic force acts toward both the ends along a circumferential direction of the repulsive tool  162 , and accordingly, both the pressing tools S 130  and S 130  can press and hold the application member  300  on the pedestal portion  222  through contact portions. On the other hand, when the pair of pressing tools S 130  and S 130  are pinched with knob portions to approach each other against the elastic force of the repulsive tool  162 , the contact portions of both the pressing tools S 130  and S 130  can be separated from the application member  300 , and the application member  300  can be released, but since the repulsive tool  16  moves to extend outward with this release operation, the passage holes  163 , the holding holes  164 , and the clearance holes  165  each are formed with a margin not to interfere with the movement of the repulsive tool  16 . 
     According to the present modification example, since the operation of the repulsive tool  162  is regulated by the passage holes  163 , the holding holes  164 , and the clearance holes  165 , similarly to the case of the embodiment illustrated in  FIGS.  1 ( a ) to  1 ( c ) , the operation of the repulsive tool  162  is reliably and easily performed, and accordingly, a pressing force of the repulsive tool  162  is reliably and sufficiently transmitted to the pressing tools S 130  and S 130 , and even when the repulsive tool is subjected to a force in the radial direction or sometimes in the axial direction, the repulsive tool is not removed from the applicator body, and the function of the medicine applicator is not impaired. Incidentally, similarly to the guide rails  160  and the like according to the embodiment illustrated in  FIGS.  1 ( a ) to  1 ( c ) , the passage holes  163 , the holding holes  164 , and the clearance holes  165  according to the present modification example can function as both a regulating portion and a guide portion. 
     (10) 
     Further, a modification example illustrated in  FIGS.  17 ( a ) to  17 ( d )  may be implemented. A medicine applicator T 100  illustrated in the same drawing has the same configuration as that of the medicine applicator S 100  according to Modification Example (9), except that a plurality of the repulsive tools  162  made of leaf springs (or wire springs or the like) are provided. A pressing tool T 130  according to the present modification example has the same configuration as that of the pressing tool S 130  according to Modification Example (9), except that passage holes  166  and  166  and holding holes  167  and  167  are provided in the vicinities of both end portions in a width direction of an upper end edge-vicinity portion and a lower end edge-vicinity portion, respectively, to be slightly separated from a through-hole T 134  to both sides in the width direction. Then, similarly to the repulsive tools  162  according to Modification Example (9), two repulsive tools  162  and  162  are disposed using the passage holes  166  and  166  and the holding holes  167  and  167 . 
     According to the present modification example, since the plurality of repulsive tools  162  are provided, elastic forces of the repulsive tools  162  can act more effectively, and an operation of the repulsive tools  162  can be more stabilized. Further, since the repulsive tools  162  are disposed to avoid the position of the through-hole T 134 , the repulsive tools  162  do not interfere with the arm  10 , and therefore, the need for providing a clearance hole in the arm  10  can be eliminated. 
     Incidentally, a plurality of the repulsive tools may be provided which include the repulsive tools passing through the respective clearance holes  165  and  165  of the arm S 10  as in the repulsive tools  162  according to Modification Example (9), and regardless of a disposition mode, three or more repulsive tools may be provided. 
     (11) 
       FIGS.  18 ( a ) to  18 ( c )  illustrate a further modification example of the medicine applicator according to the invention. A medicine applicator U 100  illustrated in the same drawing is such that a repulsive tool  168  is provided on the pedestal portion  222  side of a peripheral surface of an arm U 10 . 
     In the present modification example, on the pedestal portion  222  side (lower side in  FIGS.  18 ( a ) and  18 ( b ) ) of the peripheral surface of the arm U 10 , recessed grooves  169  and  169  each being recessed in a shape that is tapered in a substantially triangular shape in a cross-sectional view are provided at respective positions adjacent to the outsides in a length direction with respect to the pedestal portion  222 , and repulsive tool holding shafts  170  and  170  are provided across inmost portions inside the respective recessed grooves  169  and  169  along a width direction of pressing tools U 130 . The repulsive tool  168  is made of a kick spring, a bent portion  1681  is formed at one end portion thereof, and a coil portion thereof is wound around the repulsive tool holding shaft  170 . The pressing tool U 130  has the same configuration as that of the pressing tool  130  according to the embodiment illustrated in  FIGS.  1 ( a ) to  1 ( c ) , except that a guide rail  171  is formed in a front surface (surface opposite a pedestal portion  222 -side surface), the guide rail  171  extending linearly from a position that is slightly offset to one in the width direction from a center of a contact portion U 132 -side end edge portion (lower end edge portion in  FIGS.  18 ( a ) and  18 ( b ) ) of a through-hole U 134  toward a lower end edge of the pressing tool  130 . Namely, the guide rail  171  is provided in a surface of the pressing tool U 130  opposite a direction in which the contact portion U 132  is bent, to extend linearly from a position that is slightly offset to one from a center of a short side forming a contact portion U 132 -side end of the pressing tool U 130 , along a length direction (up-down direction in  FIGS.  14 ( a ) and  14 ( b ) ) of the pressing tool U 130  until the guide rail  171  communicates with the through-hole U 134 . 
     In the present modification example, the bent portion  1681  of the repulsive tool (kick spring)  168  is fitted into the guide rail  171  and presses the contact portion U 132 -side end portion in the front surface of the pressing tool U 130  while sliding in the guide rail  171 , and on the other hand, an end portion of the repulsive tool (kick spring)  168  opposite a bent portion  1681 -formation side comes into contact with one inclined surface in the recessed groove  169  and is stopped. With this configuration, an elastic force of the repulsive tool (kick spring)  168  can act on the pressing tool U 130 . 
     Incidentally, for example, the repulsive tool  168  made of a kick spring according to the present modification example may be changed to a repulsive tool made of a leaf spring, or the like. 
     (12) 
       FIGS.  19 ( a ) to  19 ( c )  illustrate a further modification example of the medicine applicator according to the invention. A medicine applicator V 100  illustrated in the same drawing is provided with a finger contact portion  172  in addition to having the same configuration of the medicine applicator  100  according to the embodiment illustrated in  FIGS.  1 ( a ) to  1 ( c ) . 
     In the present modification example, finger contact portions  172 A and  172 B are provided on a peripheral surface of an arm V 10  at respective positions that are slightly spaced from a groove V 232  to both outer sides in a length direction (may span to the through-hole of the pressing tool  130 , but is spaced not to interfere with the operation of the pressing tool  130 ). Of the finger contact portions  172 , a finger contact surface  1721 A extending outward from a surface opposite a pedestal portion  222  side (upper side in  FIG.  19 ( a ) ) on the peripheral surface of the arm V 10  to form a mountain shape of which a tip is rounded in a front view is formed in the finger contact portion  172 A on an extending portion V 14  side, both side surfaces extend in a slope shape from both hypotenuses of the finger contact surface  1721 A to converge at one point portion that is slightly spaced toward the groove  232  on the peripheral surface of the arm V 10 , and the finger contact portion  172 A is formed in a three-dimensional shape as a whole that protrudes in a substantially triangular pyramid shape from the peripheral surface of the arm V 10 . A ridge line portion (intersecting line portion between both the side surfaces) extending from a top of the finger contact portion  172 A toward the groove V 232  while being inclined downward extends while maintaining a cross-sectional shape that is continuous from tips of the finger contact surface  1721 A and that is rounded, and a tip portion at which the ridge line portion intersects the peripheral surface of the arm V 10  is also formed to be rounded in a plan view. In addition, as illustrated in  FIG.  19 ( c ) , the finger contact surface  1721 A is formed to be round recessed in a substantially arc shape from the peripheral surface of the arm V 10  outward and slightly inward as a whole in a side view. 
     In the present modification example, as illustrated in  FIG.  19 ( c ) , the pressing tool  130  on a grip portion V 11  side can be opened and closed by placing one finger (for example, thumb) F 1 A on the finger contact surface  1721 A of the finger contact portion  172 A on the extending portion V 14  side and placing another finger (for example, index finger) F 2 A on a front surface side of the knob portion of the pressing tool  130  on the grip portion V 11  side, and by performing pinching with the fingers F 1 A and F 2 A. On the other hand, the pressing tool  130  on the extending portion V 14  side can be opened and closed by placing one finger (for example, index finger) F 1 B on a finger contact surface of the finger contact portion  172 B on the grip portion V 11  side and placing another finger (for example, thumb) F 2 B on a front surface side of the knob portion of the pressing tool  130  on the extending portion V 14  side, and by performing pinching with the fingers F 1 B and F 2 B. Since the finger contact portions  172  are provided in such a manner, an individual opening and closing operation of one pressing tool  130  of the pair of pressing tools  130  and  130  is also facilitated, so that the operability is improved. 
     The finger contact portions  172 A and  172 B may be individually formed and integrated by being joined to the peripheral surface of the arm V 10 , or may be integrally formed with the arm V 10  at the same time. In addition, the shape of the finger contact portion can be any shape such as a box shape, a columnar shape, a flake shape, and a knob shape, and for example, at least a part of the finger contact portion may be configured to be expandable and contractable, or a sliding structure may be adopted in which the finger contact portion is slidable in a longitudinal direction of the arm V 11  to adjust a width between individual fingers. 
     In addition, needless to say, the finger contact portion can also be applied to, for example, a medicine applicator according to another mode such as a mode in which grip portions are provided at both end portions of an arm.

       FIGS.  20 ( a ) to  20 ( c )  illustrate a further modification example of the medicine applicator according to the invention. A medicine applicator W 100  illustrated in the same drawing is such that an arm W 10  is provided with an assist foot  173  for operating pressing tools W 130 . 
     In the present modification example, the assist foot  173  is provided at a position that is slightly offset to a grip portion W 11  side from a centralization portion W 220  in the arm W 10 . The assist foot  173  has a plate shape that gradually extends outward from a peripheral surface of the arm W 10  in a radial direction to form a substantially triangular shape in a front view, and corners of both tips are formed in a round chamfered shape. In addition, as illustrated in  FIG.  20 ( c ) , the assist foot  173  has a shape that is curved from both end portions to a central portion to bulge slightly to the grip portion W 11  side in a substantially arc shape in a bottom view. 
     The assist foot  173  is integrated with the peripheral surface of the arm W 10 , and this integration may be integration by joining the assist foot  173  to the arm W 10  or by integrally forming both at the same time, but in order to improve the stability or to prevent the assist foot from being lost, it is desirable that the assist foot is configured to be non-detachably fixed to the arm W 10 . 
     However, for example, as illustrated in  FIG.  21   , an arm W 10   a  may be provided with an attachable and detachable portion  174  from which an assist foot  173   a  is attachable to and detachable. The attachable and detachable portion  174  illustrated in the same drawing is configured by bonding or embedding a magnetic body to at least a surface of the arm W 10   a  or inside an arm portion, and on the other hand, similarly, at least a corresponding location of the assist foot  173   a  (portion that is in contact with the peripheral surface of the arm W 10   a ) is also made of a magnetic body, and accordingly, the assist foot  173   a  is freely attachable to and detachable from the arm W 10   a.  Further, for example, the arm and the assist foot may be configured to be detachably coupled to each other through a hole and a shaft in a physical structure without using a magnetic body. 
     In such a case, when a user uses the medicine applicator, the assist foot  173   a  is removable, and application can be performed without the assist foot interfering with a clothing worn by the user. 
     The medicine applicator W 100  (and W 100   a ) according to the present modification example can be placed on a flat surface such as a floor surface while being supported by tip edges of the assist foot  173 , but at this time, the center of gravity of the medicine applicator W 100  is located at a position that is slightly offset to the grip portion W 11  side from the assist foot  173 , and for this reason, the medicine applicator W 100  takes an inclined posture in which with a tip of the assist foot  173  as a fulcrum, a grip portion W 11 -side end descends to come into contact with the flat surface while the centralization portion W 220  floats up. Therefore, in this inclined posture, tips of the pressing tools W 130  are held to be always separated from the flat surface. Since it is possible to attach and detach the application member while operating the pressing tools W 130  without interference with the flat surface, the application member can be easily attached and detached. Since the applicator body is separated from the flat surface and does not interfere therewith, the arm W 10  and the assist foot  173  can be set at any angle in the radial direction of the arm W 10 . 
     Incidentally, for example, in a mode in which the position of the center of gravity is varied by providing the grip portions at both end portions of the arm, the above-described inclined posture may not be obtained as it is, but even in such a case, the above-described inclined posture may be obtained, for example, by disposing an appropriate weight at one end portion of the arm. 
     (14) 
       FIGS.  22 ( a ) and  22 ( b )  illustrate further modification examples of the medicine applicator according to the invention. Each of medicine applicators Y 100   a  and Y 100   b  illustrated in  FIGS.  22 ( a ) and  22 ( b )  includes a self-standing foot  175 ,  FIG.  22 ( a )  is an example in which a self-standing foot  175   a  is provided at an extending portion Y 14   a -side end, and  FIG.  22 ( b )  is an example in which a self-standing foot  175   b  is provided at a grip portion Y 11   b -side end. 
     The self-standing foot  175   a  illustrated in  FIG.  22 ( a )  is formed in a substantially conical shape in which the diameter gradually increases from the extending portion Y 14   a -side end of an arm Y 10   a  having a round rod shape further toward the outside. Namely, the self-standing foot  175   a  is formed in a substantially truncated cone shape in which an upper surface has a circular shape of substantially the same dimension as the lateral cross section of an extending portion Y 14   a  of the arm Y 10   a  and a bottom surface has a circular shape with a larger diameter (larger area) than the lateral cross section of the extending portion Y 14   a.  It is desirable that a part or the entirety (at least a part) of the self-standing foot  175   a  is made of a material having a higher specific gravity than that of the material of the arm Y 10   a  (for example, a combination in which the arm Y 10   a  is made of ABS resin and the self-standing foot  175   a  is made of lead). The self-standing foot  175   a  may be integrally formed with the arm Y 10   a,  and for example, may be configured to be attachable to and detachable from the arm Y 10   a  by a magnetic body similarly to the case of the assist foot  173   a  illustrated in  FIG.  21   , or may be configured to be attachable and detachable by a coupling structure using a hole and a shaft. Furthermore, for example, at least outer end surface (lower end surface in  FIG.  22 ( a ) ) of the self-standing foot  175   a  may be configured to have magnetism, so that the self-standing foot  175   a  adheres to a metal surface during its use through the magnetism, or the self-standing foot  175   a  may adhere to a surface through a suction disk. 
     The self-standing foot  175   b  illustrated in  FIG.  22 ( b )  has basically the same configuration as that of the self-standing foot  175   a  illustrated in  FIG.  22 ( a ) , but since the self-standing foot  175   b  is provided to a grip portion Y 11   b  having a slightly larger diameter than that of other portions of an arm Y 10   b,  an upper surface of the self-standing foot  175   b  also has a diameter that is slightly large by the amount. 
     Incidentally, the self-standing foot may be provided at either end portion of the arm, or the self-standing foots may be provided at both end portions, but at least in order to improve the stability during self-standing, it is desirable that the self-standing foot is provided at an end portion of the arm on the side at which the center of gravity is located. In addition, even in this case, the position of the center of gravity may be adjusted by a weight or the like. 
     In the medicine applicators Y 100   a  and Y 100   b  according to the present modification examples, the bottom surfaces of the self-standing foots  175   a  and  175   b  are disposed to stand on a surface such as a floor surface, so that a self-standing posture (standing posture) can be held. Accordingly, for example, the work of replacing the application member such as cotton puff can be easily performed, and there is an advantage in accommodating or storing the medicine applicators Y 100   a  and Y 100   b.    
     (15) 
       FIGS.  23 ( a ) and  23 ( b )  illustrate other examples of the self-standing foot,  FIG.  23 ( a )  is an example in which a self-standing foot  176  is provided at an extending portion Z 14   a -side end, and  FIG.  23 ( b )  is an example in which the self-standing foot  176  is provided at a grip portion Z 11   b -side end. The self-standing foot  176  according to the present modification example can function in substantially the same manner as the self-standing foot  175  according to Modification Example (14). 
     The self-standing foot  176  according to the present modification example is configured such that a support shaft  176 F is provided on a base plate  176 B. The base plate  176 B has a rectangular plate shape and is disposed to lie flat on a surface, and the support shaft  176 F having a round rod shape extends upward from a central portion of an upper surface of the base plate  176 B. 
     In a medicine applicator Z 100   a  illustrated in  FIG.  23 ( a ) , a shaft hole  177   a  having a circular cross section is recessed to extend linearly from a center of an extending portion Z 14   a -side end surface of an arm Z 10   a  along an axial direction of the arm Z 10   a.  An inner diameter and a length (depth) of the shaft hole  177   a  are set such that the support shaft  176 F of the base plate  176 B is easily insertable into or removable from the shaft hole  177   a  and the support shaft  176 F can be held in the shaft hole  177   a  without rattling. 
     Since a medicine applicator Z 100   b  illustrated in  FIG.  23 ( b )  has the same configuration as that of the medicine applicator Z 100   a  illustrated in  FIG.  23 ( a )  except that a shaft hole  177   b  is provided at a pip portion Z 11   b -side end, the medicine applicator Z 100   b  is configured such that the same self-standing foot  176  can also be applied. 
     The medicine applicators Z 100   a  and Z 100   b  according to the present modification examples can easily hold a self-standing posture with a simple configuration similarly to the case of the medicine applicators Y 100   a,  and Y 100   b  according to Modification Example (14), but in addition thereto, the attachment and detachment of the self-standing foot  176  is facilitated. 
     (16) 
     Further, for example, the self-standing foot can also be configured as illustrated in  FIGS.  24 ( a ) and  24 ( b ) . A self-standing foot  178  according to the present modification example holds an arm P 10  of a medicine applicator P 100  so as to be gripped from the outside,  FIG.  24 ( a )  is an example in which an extending portion P 14 -side end portion of the arm P 10  is gripped, and  FIG.  24 ( b )  is an example in which a grip portion P 11 -side end portion of the arm P 10  is gripped. 
     A self-standing foot  178   a  illustrated in  FIG.  24 ( a )  is formed in a rectangular parallelepiped outer shape, and a support hole  179   a  configured such that the extending portion P 14 -side end portion of the arm P 10  is easily insertable into or removable from the support hole  179   a  and can be held therein without rattling is provided at a central portion of an upper surface of the self-standing foot  178   a.  A self-standing foot  178   b  illustrated in  FIG.  24 ( b )  has the same configuration as that of the self-standing foot  178   a  illustrated in  FIG.  24 ( a )  except that a support hole  179   b  has a slightly large diameter to correspond to the grip portion P 11 -side end portion. 
     The self-standing foot  178  ( 178   a  and  178   b ) according to the present modification example can function in substantially the same manner as the self-standing foot  176  according to Modification Example (15). 
     (17) 
     For example, similarly to the case of the self-standing foot  175  according to Modification Example (14), as a configuration of the self-standing foot, the self-standing foot may be configured to have magnetism, so that the self-standing foot adheres to a metal surface through the magnetism, or the self-standing foot may adhere to a surface through a suction disk. 
     (18) 
       FIGS.  25 ( a ) to  25 ( e )  illustrate further modification examples of the medicine applicator according to the invention. A medicine applicator H 100  illustrated in  FIG.  25 ( a )  is an example in which an arm H 10  is provided with a low-rigidity portion  182  having a relatively low rigidity, and  FIGS.  25 ( b ) to  25 ( e )  are views specifically illustrating various configuration examples of the low-rigidity portion  182 . 
     As illustrated in  FIG.  25 ( a ) , the low-rigidity portion  182  is provided between a centralization portion H 220  and a grip portion H 11  in the arm H 10  at a position that is slightly offset to the centralization portion H 220 . As a more specific configuration example, a low-rigidity portion  182   b  illustrated in  FIG.  25 ( b )  is formed by reducing the cross-sectional area of the corresponding portion of the arm H 10 . Further, for example, in addition to reducing the cross-sectional area in such a manner or in combination therewith, the corresponding portion of the arm H 10  may be made of a material having a relatively low rigidity (for example, polyethylene or the like). A low-rigidity portion  182   c  illustrated in  FIG.  25 ( c )  is such that the corresponding portion of the arm H 10  is formed in a bellows shape. A low-rigidity portion  182   d  illustrated in  FIG.  25 ( d )  is such that the corresponding portion of the arm H 10  is formed in a wave shape or in a continuous S shape (meandering shape). A low-rigidity portion  182   e  illustrated in  FIG.  25 ( e )  is configured such that a filling material (for example, liquid silicone rubber or the like)  183  is clamped in gaps formed by the wave shape of the low-rigidity portion  182   d  illustrated in  FIG.  25 ( d )  and the filling material and the corresponding portion are joined to each other by bonding or the like. 
     In the low-rigidity portion  182  according to the present modification examples, the rigidity of the corresponding portion of the arm H 10  is lowered to impart “flexibility”, and accordingly, a burden on the wrist or the arm of a user can be reduced. 
     When the low-rigidity portion is provided, the low-rigidity portion may be provided at a part of the arm H 10  as in the present modification examples, or may be provided over the entirety of the arm. In other words, the low-rigidity portion may be provided at least a part of the arm. 
     In addition, in the medicine applicator H 100  according to the present modification example, a low-rigidity layer  184  may be provided on a use surface (surface that the body of the user contacts) of a pedestal portion H 222 , and the low-rigidity layer  184  is formed by applying a low-rigidity material such as liquid silicone rubber to the use surface of the pedestal portion H 222 . The low-rigidity layer  184  can reduce hardness, burden, or the like on the skin of the user. Even when such a low-rigidity layer is provided, the low-rigidity layer may be provided on the entirety of the pedestal portion, in other words, may be provided at least on the use surface of the pedestal portion. 
     (19) 
       FIGS.  26 ( a ) to  26 ( c )  illustrate a further modification example of the medicine applicator according to the invention. In a medicine applicator G 100  illustrated in the same drawing, pressing tools G 130  each have configurations such as a through-hole G 134  similarly to the pressing tools  130  according to the embodiment illustrated in  FIGS.  1 ( a ) to  1 ( c ) , and similarly, the pressing tools G 130  are swingably attached to an arm G 10 , and both side portions of contact portions extend to wrap around side surface portions of a pedestal portion G 222 , and accordingly, extending pieces G 139  are formed. 
     In the present modification example, as illustrated in  FIG.  26 ( c ) , the pedestal portion G 222  is formed in a substantially octagonal shape in which four corners of a square are cut off to form hypotenuses in a bottom view, namely, a three-dimensional shape including a total of ten surfaces that are eight side surfaces, an upper surface, and a lower surface. On the other hand, the extending pieces G 139  of the pressing tools G 130  according to the present modification example extend diagonally along side surfaces of the four corners of the pedestal portion G 222  to extend outward in a bottom view, and the contact portions form a substantially angled arch shape in a bottom view as a whole. 
     The extending pieces G 139  according to the present modification example are shaped to extend outward as described above, so that the extending pieces G 139  can easily and reliably press the pedestal portion G 222  without getting suck to the side surface portions of the pedestal portion G 222 . 
     As the shape of the contact portions including the extending pieces, in addition to a substantially angled arch shape in a bottom view as described above, for example, various shapes such as a substantially channel shape in a bottom view, a substantially C shape in a bottom view, and a substantially arc shape (arch shape) in a bottom view can be adopted, and the shape of the pedestal portion may be formed along substantially a shape of a pedestal portion side of the contact portions. In addition, the shape of the pedestal portion can also be a substantially circular column or elliptical column shape, and the shape can be more suitable for the skin surface of the user. 
     Incidentally, each embodiment is provided as an exemplary example and does not limit the invention. The scope of the invention is set forth in the appended claims. 
     INDUSTRIAL APPLICABILITY 
     The invention can be applied to the medicine applicator, the medicine application kit, and the pressing tool for a medicine applicator for applying, for example, a medicine or a cosmetic.
