[Problems to be Solved by the Invention] 0004 [0004] However, in the structure disclosed in Patent Document 1, the pair of sub-grip portions of the pair of connecting portions are configured to be rotated by individual pivot points. This is because, when the pair of sub-grip portions is held and used at a time, adjustment of the increase and decrease of the relative strength of the pair of sub-grip portions is difficult, and the skin surface may not be sufficiently pinched. In addition, the elastic pushing force for returning the pair of sub-grip portions to the initial state must be considered because the pair of sub-grip portions are rotated by individual turning fulcrum points, so the degree of freedom in designing the elastic pushing member reduce. [0005] The present invention has been developed in view of such a background, and it is intended to provide a cosmetic device capable of improving a cosmetic effect. [Means for Solving the Problems] [0007] One aspect of the present invention is a cosmetic device including a grip, which is a pair of sub-grip portions and a connecting portion, and the connecting portion is a unit The pair of auxiliary grip parts can be opened and closed to be connected; the shaft part is supported by the pair of auxiliary grip parts respectively; the roller is arranged on the shaft part, and can be centered on the axis of the shaft part It is rotatably supported; and an elastic pushing member that generates elastic pushing force for returning the relative positional relationship of the pair of auxiliary grip portions to an initial state, the connecting portion has a pivot point, and the pair of auxiliary grips The part is configured to perform an opening / closing operation by rotating around the rotation fulcrum. [Effects of the Invention] [0007] In the above-mentioned cosmetic device, the pair of auxiliary grip portions are connected by a connecting portion, and the opening and closing operation is performed by rotating around a pivot fulcrum of the connecting portion. Thereby, it is easier to adjust the increase and decrease of the relative power in the pair of sub-grip parts than when the pair of sub-grip parts are rotated at individual rotation fulcrum points. As a result, it is easy to pick up the skin surface, and it is possible to improve the beauty effect. In addition, regarding the spring thrust force for returning the pair of auxiliary grip parts to the initial state, it is not necessary to consider the case where the pair of auxiliary grip parts are rotated with individual rotation fulcrum points, so that the ejection member can be prevented. Reduced design freedom. [0008] In addition, a pair of auxiliary grip portions supports the shaft portions of a pair of rollers, and is connected so as to be openable and closable. With this, the user can push the pair of auxiliary grips away by pressing the pair of rollers against the part that wants a cosmetic effect, and can adjust the pair appropriately according to the shape of the used part. Wheel interval. As a result, the above-mentioned cosmetic device is suitable for a user from a relatively undulating portion such as a face or a wrist to a relatively undulating portion such as the abdomen. [0009] In the above-mentioned cosmetic device, a user can easily adjust the pressing force applied to a part where a cosmetic effect is desired by adjusting the degree of opening and closing of a pair of auxiliary grip portions. Therefore, the operation of the cosmetic device is easy. In addition, the pressing force caused by a pair of rollers can be expected to promote the blood circulation of the skin of the pressed part, or to activate the effects of metabolism, etc., and can be expected to provide excellent beauty such as skin beauty. effect. [0010] The cosmetic device is an elastic pushing member having an elastic pushing force for returning the relative positional relationship between the pair of auxiliary grip portions to an initial state. As a result, when the pair of auxiliary grips are turned in the opening direction, and the interval between the pair of rollers is widened, the elastic pushing force caused by the elastic pushing member acts on each of the rollers, bringing the pair of rollers closer to each other. Push in direction. Therefore, a large pressing force can be appropriately applied to a portion sandwiched between the pair of rollers. As a result, a more excellent cosmetic effect can be expected. [0011] As described above, according to the present invention, it is possible to provide a cosmetic device capable of improving a cosmetic effect.

[Form for Implementing the Invention] [0013] In the present specification, The above "initial state" means: Without using the above-mentioned beauty devices, In addition, there is no state in which a part intended to obtain a cosmetic effect is sandwiched between a pair of rollers. [0014] Preferably, the pair of sub-grip portions has a twist prevention member, The twist prevention member, This is to prevent the pair of auxiliary grips from twisting when they are rotated around the pivot point. When pressing a pair of rollers against the skin, If the pair of auxiliary grip parts are deformed torsionally, The tilt angle of the axis of the shaft portion supported by the pair of auxiliary grip portions changes. With this, The pinch-up of the skin surface caused by the pair of rollers supported by the shaft portion cannot be sufficiently performed, There is a concern that the cosmetic effect will be reduced. but, As described above, since the pair of auxiliary grip portions is prevented from being twisted by the twist prevention member, and so, The tilt angle of the axis of the shaft portion supported by the pair of auxiliary grip portions can be maintained. the result, The skin surface caused by a pair of rollers can be fully lifted, And prevent the reduction of beauty effects. In terms of torsion prevention members, As long as it is high rigidity, Can take a variety of aspects. [0015] The pair of auxiliary grip portions has an appearance forming portion forming an outer surface of the pair of auxiliary grip portions, The above-mentioned twist preventing member, Is arranged inside the appearance forming part, Furthermore, it is desirable to form it from the core material which has higher rigidity than the said surface formation part. at this time, The core material serving as a twist prevention member can prevent twisting of a pair of auxiliary grip portions and prevent a decrease in the cosmetic effect. The appearance forming portion becomes a shape that a user can easily hold, Or achieving a high design shape can improve the degree of design freedom. The shape and material of the core material, As long as the rigidity such as the twisting direction of the pair of auxiliary grip portions is sufficiently high, Can take a variety of aspects. E.g, By using a metal plate as the core material, It can fully improve the rigidity of the core material. also, By using a relatively strong metal plate such as a stainless steel plate, Or by increasing the thickness of the plate, It can further increase the rigidity of the core material. usually, Use stainless steel plate as core material, In this way, sufficient rigidity can be obtained, I prevent twisting of a pair of sub grip parts, And prevent the reduction of beauty effects. [0017] The core material is in a longitudinal direction of the pair of auxiliary grip portions, Ideally, it is set to be more than half of the length in the longitudinal direction of the pair of sub grip portions. at this time, The increased rigidity of the pair of sub-grip portions can further prevent twisting of the pair of sub-grip portions. [0018] Moreover, The core material of the pair is in the longitudinal direction of the auxiliary grip portion of the pair, The entirety of the auxiliary grip portions provided in the pair is more desirable. at this time, The rigidity of the pair of auxiliary grip parts is further improved, Furthermore, twisting of the pair of auxiliary grip portions can be further prevented. [0019] A pair of the core materials each have a through hole at an end portion thereof, The rotation fulcrum of the connection portion, Are the above through-holes in which the above-mentioned pair of core materials are overlapped on the same axis, It is preferable to insert a grip shaft into this through hole. at this time, With a simple structure, a pair of auxiliary grip parts can be rotated with one rotation fulcrum. [0020] the core material, It is preferable to provide a shaft support part which supports the said shaft part in the edge part opposite to the edge part provided with the said through hole. at this time, The degree of opening and closing of a pair of auxiliary grip parts is adjusted by the user, The interval between a pair of rollers can be changed. therefore, It is easy for the user to grasp the size of the opening and closing movements of the pair of auxiliary grips, Relationship with the amount of change in the interval of a pair of rollers. also, By adjusting the degree of opening and closing of the pair of auxiliary grip parts, It is easy to adjust the pressing force applied to the part where the cosmetic effect is desired. the result, Makes it easier to operate the cosmetic device, You can expect more excellent cosmetic results. [0021] The pair of shaft portions is in an initial state, The distance from the base of the grip side toward the front end side can be extended so that the interval between the pair of axes is enlarged. at this time, When pressing the above cosmetic device against the skin, The distance between the pair of rollers can be easily pushed away. the result, The said cosmetic device becomes easier for a user to operate. [0022] Also, In the above mentioned pushing member, For example, using spring members, Rubber etc. Among these, As far as the above-mentioned ejection member is concerned, It is desirable to use a metal spring member. Metal spring member, It is easy to moderately increase the above-mentioned bomb thrust. the result, With the use of the above cosmetic equipment, Expect even better cosmetic results. [0023] Also, In the above initial state, The pair of rollers may be separated from each other. at this time, When the pair of rollers is pressed against the part that wants to obtain a cosmetic effect, A state where the part is sandwiched between the rollers to a certain extent can be naturally realized. With this, This makes it easier to sandwich the part you want to get a cosmetic effect between the rollers, It becomes easier for users to operate. In addition, In the above initial state, When the pair of rollers are separated from each other, The interval between the pair of rollers in the initial state can be appropriately set in a range of 1 to 50 mm. [0024] Again, The pair of shaft portions may often be arranged in the above-mentioned opened state. at this time, The pressure sandwiched between the pair of rollers is moderately increased. And you can expect superior cosmetic results, In addition, the ease of operation of the cosmetic device can be further improved. [0025] Again, The grip is preferably inclined with respect to a plane including the pair of axes. at this time, By causing the grip to press the pair of rollers against the skin surface along the skin surface, On the other hand, the plane including the pair of axes is inclined with respect to the skin surface. and, Moving the cosmetic device while maintaining this state, With this, A pair of rollers can be used to deform the part that wants to obtain a cosmetic effect in a pinch manner. the result, With the use of the above cosmetic equipment, Expect even better cosmetic results. [0026] Again, The above mentioned functions of pinching the skin, Is changed according to the interval of a pair of rollers, And keep the interval of a pair of rollers in a proper range, With this, The above effect can be felt. therefore, When the grip is inclined with respect to a plane including the axes of the pair, By further setting the opening and closing restrictions, I feel the above effect, Furthermore, a more excellent cosmetic effect can be expected. [0027] Again, The above-mentioned roller can be made into a spherical shape. at this time, The pressing force of the roller is easy to concentrate on the part sandwiched between a pair of rollers. So you can fully increase the physical pressure, You can expect more excellent cosmetic results. also, at this time, The rollers can be rotated smoothly while pressing the pair of rollers against the skin. The ease of operation of the cosmetic device can be further improved. [0028] Furthermore, The above-mentioned slightly spherical shape includes: Sphere, Twist the sphere into a spheroid, In general, the teardrop shape is considered to be a spherical shape. also, The roller may have a surface formed by a smooth curved surface, For example, it can also have many triangles, Polyhedron with a surface composed of a quadrangle, etc. When the roller is a polyhedron, Compared to a roller with a surface made of a smooth curved surface, Can prevent the surface of the roller from sliding against the skin, You can expect more excellent cosmetic results. [0029] Again, The grip has a solar panel, It can also constitute the electromotive force by the solar panel, Let electric current flow to the human skin in contact with the roller. at this time, With the current flowing to the human skin, Activates skin cells, And there will be better lymphatic flow, Or promote blood circulation, Or the possibility of improving the effects of metabolism, etc. the result, With the use of the above cosmetic equipment, Expect even better cosmetic results. [0030] In another aspect of the invention, Is a beauty device, among them, have: Grip It is equipped with a pair of auxiliary grip parts, And the link, The connecting portion is capable of opening and closing the pair of auxiliary grip portions; Shaft Are respectively supported by the pair of auxiliary grip parts; Scroll wheel, It is arranged on the shaft part, And is rotatably supported around the axis of the shaft portion; As well as popping components, This is caused by the elastic thrust for returning the relative positional relationship of the pair of auxiliary grip parts to the initial state. The connecting portion has a pivot point, The pair of auxiliary grip portions has a twist prevention member, The twist prevention member, Rotate around the above pivot point, And the composition performs opening and closing operations, and, This prevents the pair of auxiliary grips from twisting when the center of rotation is pivoted. According to the cosmetic device, Because the twist prevention member can prevent twisting deformation of the pair of auxiliary grip portions, and so, The tilt angle of the axis of the shaft portion supported by the pair of auxiliary grip portions can be maintained. the result, The skin surface caused by a pair of rollers can be fully lifted, And prevent the decline in beauty effects. In terms of torsion prevention members, As long as it is high rigidity, Can take a variety of aspects.

[0050] Moreover, As shown in Figure 5, As shown in Figure 6, Insert the grip shaft 340 through the through hole of the disc portion 342b of the upper ferrule 342, and, The spring cover portion 342 c in the upper ferrule 342 covers a part of the upper surface and a part of the outer peripheral surface of the wound portion 510 of the spring member 51. and, A nut 347 is attached to the grip shaft 340 via two washers 345 and a spring washer 346. A part of the upper surface and a part of the outer peripheral surface of the wound portion 510 of the spring member 51 are covered by the spring cover portion 342c, The spring mechanism 51 is prevented from falling off. In addition, The spring washer 346 is located between the two washers 345. The spring washer 346 seeks to absorb the axial error of the grip shaft 340 and suppress the shake. also, With each ferrule 342-343 and washer 345, Reduced due to a pair of auxiliary grip parts 33a, The friction caused by the rotation of 33b on the grip shaft 340, etc. And prevent loosening. [0051] Moreover, As shown in Figure 7 (a), As shown in Figure 7 (b), The pair of auxiliary grip portions 33a, 33b, It is configured to be capable of being opened and closed by rotating around the grip shaft 340 as a fulcrum. and, Spring member 51, Is a pair of auxiliary grip parts 33a, 33b The spring force which is pushed in the closing direction is given to the pair of auxiliary grip portions 33a, 33b. With this, The user sets a pair of auxiliary grip portions 33a, The pair of rollers 4 at the front end of 33b is pressed against the skin surface, With this, A pair of auxiliary grip portions 33a, 33b is turned in the opening direction against the elastic thrust of the spring member 51. [0052] Moreover, As shown in Figure 8, The pair of auxiliary grip portions 33a, 33b, The restriction pin 52 of the press-in hole 383 of the core material 333 pressed into the second sub-grip portion 33b is located in the notch portion 385 of the first sub-grip portion 33a. Also shown in Figure 9, The restriction pin 52 pressed into the press-fitting hole 383 of the core material 333 of the first sub-grip portion 33a is located in the cutout portion 385 of the second sub-grip portion 33b. [0053] As shown in FIG. 5, As shown in Figure 6, 联 部 34 ， The connecting portion 34, It is covered by the cylindrical connection part cover 35. Linking part cover 35, Made of elastomer. have: In the initial state, Located in a pair of auxiliary grip parts 33a, The cover body portion 351 exposed between the rear ends of 33b, And a pair of auxiliary grip portions 33a, The rear end of 33b extends from the cover body 351, and, In the initial state shown in Fig. 7 (a), Located in a pair of auxiliary grip parts 33a, A pair of covers on the inner side of the rear end portion of 33b extend to provide the portion 352. The pair of cover extensions 352 are open at the ends in the extension direction, Assembled in a pair of auxiliary grip parts 33a, 33b, The inner space 353 of the connection part cover 35 and a pair of auxiliary grip parts 33a, The space inside 33b communicates. [0054] As shown in FIG. 6, A cylindrical inner rib 356 is provided on the inner side surface of the cover body portion 351 so as to fit inside the cylindrical portion 342 a of the upper ferrule 342. By inserting the inner rib 356 into the cylindrical portion 342a, Instead, the connection portion cover 35 may be fixed to the connection portion 34. With this, The cover body portion 351 can be prevented from following the pair of auxiliary grip portions 33a, When the opening and closing action of 33b moves. also, As shown in Figure 7 (a), A rear end portion 354 of the cover, which is an end portion in the rear direction of the cover body portion 351, is formed in a V shape. With this, With a pair of auxiliary grip parts 33a, 33b opens and closes from the initial state shown in FIG. 7 (a) to the opening direction, A pair of auxiliary grip parts 33a, 33b rotates with the grip shaft 340 as a fulcrum, As shown in Figure 7 (b), In a pair of auxiliary grip portions 33a, The rear end portion 33b narrows the interval P between the rearmost portions of the regions facing each other. and, Because the rear end portion 354 of the cover is V-shaped, and so, The pair of sub grip parts 33a, The interval P of the rearmost portion in the rear end portion of 33b is narrowed, As a result, the cover rear end portion 354 is easily compressed and deformed. on the other hand, In a pair of auxiliary grip portions 33a, The rear end of 33b, The interval Q between the front ends of the areas facing each other, As a result of the initial state shown in FIG. 7 (a), a pair of auxiliary grip portions 33a, 33b is opened from the initial state and widened as shown in FIG. 7 (b). With this, A pair of auxiliary grip parts 33a, Although the rear end portion of 33b is separated from the cover body portion 351, However, a pair of cover extension portions 352 extending from the cover body portion 351 is formed in the cover body portion 351 and a pair of auxiliary grip portions 33a, The rear ends of 33b are exposed. therefore, It is possible to prevent the cover body portion 351 and the pair of auxiliary grip portions 33a, 33b saw the situation inside. [0055] Again, as shown in picture 2, In a pair of auxiliary grip portions 33a, 33b is provided with a solar cell section 6. As shown in Figures 5 and 10, The solar cell section 6 has: Lens 61, Solar panel 62, Substrate 63, First connection member 64, 2nd connecting member 65, Powered screw 66. A pair of terminals 62a are connected to the solar cell panel 62, It is arranged on the upper surface of the substrate 63. A pair of terminals 62a, It is located above a pair of hubs 63 a provided with through holes in the base plate 63. and, The lens 61 is mounted on the substrate 63 by covering the entire area of the solar cell panel 62 with screws 61 a. Between the lens 61 and the substrate 63, A sealing member 63b is provided along the outer edge of the substrate 63. With this, Maintaining the watertightness of the space between the lens 61 and the substrate 63, The solar cell panel 62 is waterproofed from the outside. The solar cell section 6 having such a structure, As shown in Figure 11, Form a single unit. and, As shown in Figure 5, A penetrating portion 610 is formed in the grip upper side portion 332. Solar cell section 6, Therefore, the lens 61 is exposed from the penetrating portion 610 and is attached to the inner side surface of the grip upper side portion 332 by a screw 67. [0056] As shown in FIG. 10, As shown in Figure 11, A first connection member 64 and a second connection member 65 are provided on the lower surface of the substrate 63. As shown in Figure 5, The first connection member 64 and the second connection member 65 are formed with through holes 64 a through which conductive conductive screws 66 are inserted, 65a. The first connection member 64 and the second connection member 65, Is inserted into the through hole 64a, The energizing screw 66 of 65 a is screwed into a pair of hubs 63 a of the substrate 63 and is fixed to the lower surface of the substrate 63. Furthermore, As shown in Figure 10, The front ends of the energization screws 66 screwed into the pair of hubs 63 a abut against the terminals 62 a of the solar cell panel 62. With this, The first connection member 64 and the second connection member 65 are electrically connected to the terminals 62 a of the solar cell panel 62 via the energization screws 66. [0057] As shown in FIG. 10, As shown in Figure 11, The first connection member 64 includes a first connection portion 64 b that abuts on the core material 333 extending toward the core material 333. on the other hand, The second connection member 65 includes a second connection portion 65 b extending to abut on the inner side surface of the grip cover portion 334. With this, The solar cell panel 62 is electrically connected to the grip cover portion 334 and the core material 333 via the first connection member 64 and the second connection member 65. and, Because the core material 333 is electrically connected to the roller 4, and so, The user holds the grip 3, A closed circuit is formed by abutting the roller 4 on the skin surface. With this, Electric current can flow to the human body by the electromotive force of the solar cell panel 62. [0058] Next, The usage aspect of the beauty device 1 of this example is demonstrated. When using cosmetic device 1, First, the user lets a pair of auxiliary grip portions 33a, The grip cover 334 of 33b touches the palm, While holding the grip portion 32, light is incident on the solar cell portion 6. and, As shown in Figure 3, The pair of rollers 4 are pressed against the skin surface 8 so that the gripping portion 32 follows the skin surface 8. in this way, By pressing the roller 4 against the skin surface 8, The plane P including the pair of axes A is inclined with respect to the skin surface 8. [0059] From a state where the pair of rollers 4 are in contact with the skin surface 8, By further pressing the pair of rollers 4 against the skin surface 8, As shown in Figure 7 (b), The grip 3 is opened in the direction of the arrow mark 102 against the spring thrust of the spring member 51, As shown by arrow mark 100 in FIG. 4, The distance d between the pair of rollers 4 can be pushed apart. The pair of shaft portions 2 in the cosmetic device 1 of this example, Even if the interval d between the pair of rollers 4 is changed from the initial state and any of the initial states, The interval of the pair of axes A may be maintained in an extended state from the base on the grip 3 side toward the distal end side. that is, Beauty device 1 of this example, Is the composition often becomes a stretched state. [0060] Moreover, If a pair of auxiliary grip parts 33a, 33b opens from the initial state, And as shown in Figure 8, As shown in Figure 9, The core material 333 of the first auxiliary grip portion 33a is rotated in the direction of the arrow mark 102a with the grip shaft 340 as a fulcrum, and, The core material 333 of the second sub grip portion 33b is rotated in the direction of the arrow mark 102b with the grip shaft 340 as a fulcrum. Along with this, The restriction pin 52 moves in the backward direction. and, If the two core materials 333 are rotated by a predetermined amount in the opening direction, The restriction pin 52 abuts on the rear end surface 385a of the notch portion 385, However, the two core materials 333 are restricted from turning in the opening direction. also, In the initial state, While the core material 333 of the first sub-grip portion 33a is pushed in the direction of the arrow mark 102b by the spring member 51, The core material 333 of the second sub-grip portion 33b is elastically pushed in the direction of the arrow mark 102a. With this, A pair of auxiliary grip parts 33a, 33b while being pushed in the closing direction, The restriction pin 52 abuts the front end surface 385b of the notch portion 385, However, the two core materials 333 are restricted from turning in the closing direction. [0061] The restriction pin 52 and the cutout portion 385 in the cosmetic device 1 of this example, Is designed so that a pair of auxiliary grip parts 33a, 33b When opening and closing, The interval d between the pair of rollers 4 can be changed within a range of 1 to 50 mm. and, Because it has a core material 333 formed of a metal plate, and so, In a state where the interval d between the pair of rollers 4 is maximized, Even if the force of pressing a pair of rollers 4 against the skin surface 8 is increased, A pair of auxiliary grip parts 33a, 33b is not easy to produce elastic deformation, On the other hand, the interval d between the rollers 4 constituting a pair does not become larger than this. [0062] Moreover, With the pair of rollers 4 in contact with the skin surface 8, By moving the cosmetic device 1 from the roller 4 side toward the grip 3 side, As shown in FIG. 3 and FIG. 4, a part that wants to obtain a cosmetic effect is wrapped between a pair of rollers 4. The skin surface 8 is changed into a state of being pinched by the pair of rollers 4. [0063] At this time, Let the beauty device 1 move, And close the pair of auxiliary grip portions 33a, Force in the direction of 33b, This can increase the pressing force applied to the portion sandwiched between the pair of rollers 4. [0064] Again, The roller 4 is in contact with the skin surface 8, While the grip cover 334 of the grip 3 is in contact with the palm, Formed containing solar panels 6, Wheel 4, The grip cover 334 and the closed circuit of the human body. therefore, By the electromotive force of the solar cell panel 62, an electric current can flow to the human skin in contact with the roller 4. [0065] Next, The effect of this example will be described. [0066] The cosmetic device 1 according to this embodiment, The pair of auxiliary grip portions 33a, 33b is connected to be able to be opened and closed by rotating the grip shaft 340 as a pivot point. With this, Compared to a pair of auxiliary grip portions 33a, 33b When turning with individual turning fulcrum, A pair of auxiliary grip parts 33a, The adjustment of the relative power increase and decrease in 33b becomes easier. the result, Easy to pick up skin surface 8, Can improve the beauty effect. also, About letting a pair of sub grip parts 33a, 33b Spring thrust for returning to the initial state, Because it is not necessary to consider a pair of auxiliary grip portions 33a, 33b the case of turning with individual turning fulcrum, and so, It is possible to prevent a reduction in the degree of freedom in design of the spring member 51 as the spring member 5. [0067] Again, A pair of auxiliary grip parts 33a, 33b while supporting the shaft portion 2 of the pair of rollers 4, It is openable and closable. With this, user, By pressing a pair of rollers 4 against the part that wants to get a cosmetic effect, A pair of auxiliary grip parts 33a, 33b, The interval d between the pair of rollers 4 can be appropriately adjusted in accordance with the shape of the part to be used. the result, Beauty device 1 of this example, Is formed to fit from the face, The user performs the user from a relatively undulating portion such as the wrist to a relatively undulating portion such as the abdomen. [0068] Again, Beauty device 1 of this example, Is a pair of auxiliary grip portions 33a, The degree of opening and closing of 33b, It is easy to adjust the pressing force applied to the part where a cosmetic effect is desired. therefore, The beauty container 1 is easy to operate. also, With the pressing force caused by a pair of rollers 4, It is expected to promote blood circulation in the skin of the pressed part, Or you can expect effects such as activation of metabolism, Further, excellent cosmetic effects such as making the skin beautiful can be expected. [0069] Again, Beauty device 1 of this example, It is equipped with the sub grip part 33a which is a pair, The relative positional relationship of 33b is returned to the spring member 51 of the elastic member by the elastic force for the initial state. With this, A pair of auxiliary grip parts 33a, 33b turns in the opening direction, In a state where the interval d between the pair of rollers 4 is widened, The elastic pushing force caused by the elastic pushing member acts on each roller 4, Push the pair of rollers 4 toward each other. therefore, It is possible to moderately apply a large pressing force to a portion sandwiched between the pair of rollers 4. the result, Expect even better cosmetic results. [0070] Furthermore, In the cosmetic device 1 of this example, A pair of auxiliary grip parts 33a, 33b has the grip shaft 340 as the pivot As a pair of auxiliary grip portions 33a, The core material 333 of the torsion preventing member in the case of 33b torsion. When pressing a pair of rollers 4 against the skin surface 8, If a pair of auxiliary grip parts 33a, 33b When twisted, A pair of auxiliary grip parts 33a, The angle θ of the shaft portion 2 supported by 33b changes, In addition, the skin surface 8 caused by the pair of rollers 4 cannot be picked up sufficiently. There is a concern that the cosmetic effect will be reduced. but, As described above, a pair of auxiliary grip portions 33a, 33b torsionally deformed, and so, Can maintain a pair of auxiliary grip parts 33a, The angle θ of the shaft portion 2 supported by 33b, And prevent the decline in beauty effects. [0071] Also, In the cosmetic device 1 of this example, A pair of auxiliary grip parts 33a, 33b has a pair of auxiliary grip portions 33a, The grip lower side portion 331 of the appearance forming portion of the outer surface of 33b, The grip upper side portion 332 and the grip cover portion 334. and, The twist prevention member is arranged inside the appearance forming portion, Further, the core material 333 has a higher rigidity than the appearance forming portion. With this, The core material 333 serving as a twist prevention member prevents a pair of sub grip portions 33a, The twist of 33b can prevent the reduction of the cosmetic effect, With the grip lower side portion 331 as the appearance forming portion, The grip upper side portion 332 and the grip cover portion 334 are shaped to be easily held by a user, Or it can be made into a shape which achieves high designability, etc., and can improve design freedom. [0072] Again, In the cosmetic device 1 of this example, A stainless steel plate was used as the core material 333. With this, Get enough rigidity, Prevent a pair of sub grip parts 33a, 33b twist, And prevent the decline in beauty effects. [0073] Also, Beauty device 1 of this example, The core material 333 is in a pair of auxiliary grip portions 33a, 33b long side direction, Across the pair of auxiliary grip portions 33a, More than half of the length in the longitudinal direction of 33b is provided. With this, A pair of auxiliary grip parts 33a, 33b increased rigidity, Further, it is possible to further prevent the pair of auxiliary grip portions 33a, 33b Twisted case. [0074] Furthermore, In the cosmetic device 1 of this example, The core material 333 is in a pair of auxiliary grip portions 33a, 33b long side direction, A pair of auxiliary grip parts 33a, 33b overall. With this, A pair of auxiliary grip parts 33a, The rigidity of 33b is further increased, which can further prevent a pair of auxiliary grip portions 33a, 33b Twisted case. [0075] Furthermore, In the cosmetic device 1 of this example, A pair of core materials 333 each have a through hole 381 at an end portion 38 thereof, The pivot of the connecting portion 34, Is a through hole 381 of a pair of core materials 333 superimposed on the same axis L1, It is configured by inserting the grip shaft 340 into the through hole 381. With this, With a simple structure, a pair of auxiliary grip parts 33a, 33b rotates with a pivot point. [0076] Furthermore, In the cosmetic device 1 of this example, The core material 333 is provided at the first end portion 37 on the side opposite to the second end portion 38 provided with the through-hole 381 with a through-hole 371 as a shaft support portion for supporting the shaft portion 2. With this, The user adjusts a pair of auxiliary grip portions 33a, The opening and closing amplitude of 33b, The interval d of the pair of rollers 4 can be changed. therefore, It is easy for a user to grasp a pair of auxiliary grip portions 33a, The size of the opening and closing action of 33b, Relationship with the amount of change in the interval d of the pair of rollers 4. also, By adjusting the pair of auxiliary grip portions 33a, The opening and closing amplitude of 33b, It is easy to adjust the pressing force applied to the part where the cosmetic effect is desired. the result, The ease of operation of the cosmetic device 1 can be improved, You can expect more excellent cosmetic results. [0077] Again, Beauty container 1, Is in a state where the interval d of the pair of rollers 4 is extended, Causing the elastic pushing force of the elastic pushing member 5 to act on each of the rollers 4, Then, the pair of rollers 4 are pushed toward each other. therefore, It is expected to promote blood circulation in the skin of the portion pressed by the pair of rollers 4, Or you can expect effects such as activation of metabolism, Further, a cosmetic effect such as making the skin beautiful can be expected. [0078] Again, Beauty container 1, It is provided with the restriction pin 52 and the cutout part 385 as an opening-closing restriction part. therefore, The beauty container 1 can surely prevent the interval d of the pair of rollers 4 from being excessively stretched, In addition, breakage of the cosmetic device 1 can be reliably prevented. [0079] Again, A pair of shaft parts 2, It is an extended state in which the intervals of the axis A are often arranged in a pair from the base on the grip 3 side toward the front end side. that is, Beauty container 1, Is to achieve the open state in the initial state, It becomes easier for the user to operate. also, The expanded state can be achieved by changing the state of the interval d between the pair of rollers 4 from the initial state, And it can moderately increase the pressing force of part of the body sensation sandwiched between a pair of rollers 4, And expect better cosmetic results. [0080] Again, The grip 3 is inclined with respect to a plane P including a pair of axes A. Furthermore, In this example, Restricting pin 52 and notch 385, Is designed so that a pair of auxiliary grip parts 33a, 33b When opening and closing, The interval d between the pair of rollers 4 can be changed within a range of 1 to 50 mm. By keeping the interval d of the pair of rollers 4 in an appropriate range, The above-mentioned effect of pinching the skin can be felt. the result, Expect even better cosmetic results. [0081] Also, The roller 4 has a substantially spherical shape. therefore, The pressing force by the roller 4 is easy to concentrate, In addition, the pressing pressure of the user's physical sensation can easily become sufficiently large. also, You can make a smoother rotation while pressing a pair of rollers 4 against your skin. The ease of operation of the cosmetic device 1 can be further improved. [0082] Also, The grip 3 has a solar cell section 6, And can constitute the electromotive force by the solar cell panel 62, Let the electric current flow to the human skin in contact with the roller 4. therefore, With the use of the beauty device 1, Expect even better cosmetic results. [0083] Again, The solar cell section 6 forms a single unit, Solar panel 62, The sealing member 63b achieves waterproofing that is sealed from the outside. With this, This is because even if the sub-grip portion 33a of the solar cell portion 6 is not secured, 33b overall waterproofness, It is also possible to ensure the waterproofness of the solar panel 62, and so, Do not ensure the sub-grip section 33a, 33b overall waterproof sealing member, Can reduce the number of parts. Furthermore, Because the solar cell section 6 forms a single unit, and so, In the sub-grip section 33a, 33b exerts an external force, And the grip lower side 331, When the grip upper side portion 332 and the grip cover portion 334 are flexed, The solar cell section 6 itself is not easily deformed. therefore, Even in this case, It is also easy to maintain the waterproofness of the solar cell panel 62. [0084] Again, In this example, With the pair of auxiliary grip parts 33a, The grip lower side portion 331 of the appearance forming portion 33b, The grip upper side portion 332 and the grip cover portion 334, Make a pair of sub grip parts 33a, The cross-section in the front-rear direction of the appearance of 33b is slightly oval. With this, The appearance forming portion and the structure can also be improved in rigidity. the result, A pair of auxiliary grip parts 33a, which can be obtained together with the core material 333, 33b improvement of overall rigidity, It is possible to further prevent the pair of auxiliary grip portions 33a, 33b reversed. [0085] Furthermore, The pair of auxiliary grip portions 33a, 33b each form an integral body formed of a metal. at this time, Because a pair of auxiliary grip parts 33a, 33b itself can function as a core material, Therefore, the pair of auxiliary grip portions 33a, 33b rigidity. the result, It is possible to further prevent the pair of auxiliary grip portions 33a, 33b deflection. [0086] a pair of auxiliary grip portions 33a, When the rigidity of 33b is excessively low, If a pair of rollers 4 is used to press the part where the cosmetic effect is desired, There will be a sub-grip section 33a, 33b Concerns about deflection. therefore, Depending on the situation, even if the pair of auxiliary grip parts 33a, 33b The opening and closing operation in the closing direction cannot sufficiently reduce the interval d between the pair of rollers 4, On the other hand, there is a possibility that the pressing force applied to a part where a cosmetic effect is desired cannot be fully felt. on the other hand, Beauty device 1 of this example, Because of the above structure, So you can avoid such problems, On the other hand, the opening and closing action of the grip 3 can sufficiently increase the pressing force applied to a cosmetic effect. The above results, Beauty container 1, It can fully increase the physical pressure, You can expect more excellent cosmetic results. [0087] As above, Beauty container 1, Is suitable for use on all parts of the body, And expect superior cosmetic results. (Evaluation test) An evaluation test by a sensory test was performed on the cosmetic device 1 of the above-mentioned example. Prepare the cosmetic device 1 of the above embodiment as a test example, A conventional cosmetic device 900 shown in FIG. 12 was prepared as a comparative example. As shown in Figure 12, Conventional beauty device 900, The pair of auxiliary grip parts 933 are made of ABS resin, Without the core material 333. Although not shown in the figure, the forward direction end part of a pair of auxiliary grip part 933, but, A pair of rollers having the same configuration as the roller 4 of the cosmetic device 1 of this embodiment is provided. [0089] Moreover, A connecting plate 953 and a plate spring 951 are provided in the connecting portion 934 of the pair of sub grip portions 933. The link plate 953 is slightly U-shaped when viewed from above. A pair of through holes 954 and a pair of restriction grooves 956 are provided. A hub 955 formed to protrude from the inner side surface of the auxiliary grip portion 933 is inserted into the pair of through holes 954. With this, A pair of auxiliary grip parts 933 are connected. also, A pair of restriction pins 952 formed inside the pair of restriction grooves 956 and protruding from the inner side surface of the auxiliary grip portion 933 are located here. In the cosmetic device 900 of this comparative example, With the hub 955 inserted through a pair of through holes 954 as a pivot point, The pair of auxiliary grip portions 933 are individually turned to be openable and closable. and, The range in which the pair of auxiliary grip portions 933 can be opened and closed is a range in which the restriction pin 952 located in the pair of restriction grooves 956 is movable in the restriction groove 956. In the cosmetic device 900 of the comparative example, The restriction pin 952 and the restriction groove 956 are set so that the distance between the rollers is in the range of 1 to 50 mm, similarly to the cosmetic device 1 of this embodiment. [0090] The evaluation method is as follows. First of all, A total of 31 males and 16 females aged 20 to 50 were selected as subjects. For evaluation test 1, In the state of covering the eyes of the subject, An applicator different from the test subject applies the cosmetic device 1 of the test example and the cosmetic device 900 of the comparative example to the calf, To evaluate the subject's physical sensation. In addition, The operator has the same strength in the cosmetic device 1 of the test example and the cosmetic device 900 of the comparative example. Surge at speed. also, For evaluation test 2, The subject himself applied the cosmetic device 1 of the test example and the cosmetic device 900 of the comparative example to his calf, To evaluate such a physical sensation. Somatosensory evaluation, After using two cosmetic devices, Choice feels like users. The following Table 1 shows the evaluation test 1 2 results. [0091] [0092] As shown in Table 1, in the evaluation test 1, the proportion of the cosmetic device 1 that wanted to use the test example was 71%, and 22 of the 31 subjects were selected as the cosmetic device 1 of the test example. On the other hand, in the evaluation test 1, the proportion of the cosmetic device 900 that wanted to use the test example was 23%, and 7 of the 31 subjects selected the cosmetic device 900 of the comparative example. In the evaluation test 2, the proportion of the cosmetic device 1 that wanted to use the test example was 84%, and 26 of the 31 subjects selected the cosmetic device 1 of the test example. On the other hand, in the evaluation test 2, the proportion of the cosmetic device 900 that wanted to use the test example was 10%, and three of the 31 subjects selected the cosmetic device 900 of the comparative example. [0093] As described above, in any of the evaluation tests 1 and 2, the proportion of the cosmetic device 1 that wants to use the test example is higher than the case of the cosmetic device 900 of the comparative example. This is presumably because the cosmetic device 900 of the comparative example does not have the core material 333. Therefore, if the roller is pressed against the skin surface, the sub grip portion 933 is twisted, and the distance between the rollers is widened, so that the skin cannot be sufficiently developed Pinch up the face, so that the sense of body is reduced. [0094] In the cosmetic device 900 of the comparative example, since the pair of auxiliary grip portions 933 are rotated at individual pivot points, a pair of auxiliary grips for maintaining the most suitable distance between the rollers is required. It is difficult to adjust the increase and decrease of the strength of the portion 933. However, in the cosmetic device 1 of the test example, the pair of auxiliary grip portions 33a and 33b are rotated by the grip shaft 340 serving as a pivot fulcrum. Adjustment of strength increase and decrease is easy. [0095] As described above, according to the evaluation tests 1 and 2, in the cosmetic device 1 of the first embodiment, it can be confirmed that the body feeling is improved compared with the cosmetic device 900 of the comparative example.
