Good.

  As shown in FIGS. 10 and 11, insertion holes 41 are provided at both left and right ends of the holder member 14. A tap screw 42 passing through the insertion hole 41 is screwed into a boss hole 43 of the boss 27, and the holder member 14 and the cassette member 13 are fixed by the tap screw 42. The insertion hole 41 of the holder member 14 is thick. Further, instead of the tap screw 42, a pin that is press-fitted into the insertion hole 41 and the boss hole 43 may be used. This pin may be integral with the holder member 14.

  As shown in FIGS. 10, 12 and 13, the cover member 15 is made of a synthetic resin suitable for painting such as ABS and PC, and its surface is painted, and the top is placed on top of the painting. Coat is given. The cover member 15 is formed by a pair of side surfaces 51 forming both side surfaces of the beauty device main body 10 and an end surface portion 52 located between the front ends of the both side surface portions 51 so as to form an almost bivalve shape as a whole. A short extension 53 is formed at each end of the end face 52. A substantially arc-shaped concave stress avoiding portion 54 is recessed at the edge of the extension portion 53. The stress avoiding portion 54 avoids stress concentration when a force in the opening direction acts on the side surface portion 51. belongs to. As shown in FIGS. 3 to 5, the outer surface of the side portion 51 of the cover member 15 is entirely convex including the central portion in the front-rear direction and the left-right direction, and the central portion of the outer surface of the side portion 51. Are concave portions 30 that gradually fall while maintaining a convex curved surface in the front-rear direction.

  Then, as shown in FIG. 18, the outer peripheral edge of the side surface portion 51 is elastically engaged with the step portion 28 of the Casser member 13, and the Caser member 13 is gripped by the cover member 15 with the Caser portion 12 exposed. I have. In this state, the portion of the casing member 13 excluding the casing portion 12 and the holder member 14 are housed between the side surface portions 51. Accordingly, the casing member 13 and the holder member 14 are covered by the side surface portions 51 except for the casing portion 12 and the rotating body 18. The spacer 21 of the cuff member 13 is in contact with or close to the inner side surface of the both side surface portions 51, and the spacer 21 suppresses the dent deformation of the side surface portion 51 toward the holder member 14.

As shown in FIGS. 10, 18, and 19, the above-described insertion hole 17 through which the support shaft 16 is inserted is provided through the end face portion 52.
Next, the support shaft 16 and the rotating body 18 and their related components will be described in detail.

  As shown in FIGS. 10 and 11, a pair of shaft support portions 61 and 62 each having a semicircular cross section are formed on both front and back surfaces of the right and left sides of the holder member 14. The shaft support portions 61 and 62 on the front and back sides of each pair communicate with each other, and their axes are inclined with respect to the front-rear direction and cross each other in plan view. The inner bottom portions of the shaft support portions 61 and 62 are formed by three bridge portions 63, respectively. Of the three erection portions 63, one of the erection portions 63 located in the middle protrudes a retaining portion 65 having a claw portion 64 at the tip. As shown in FIG. 18, a guide slope 87 is formed inside the claw portion 64.

  As shown in FIGS. 6, 7, and 8 to 10, each pair of shaft support portions 61 and 62 accommodates a support shaft 16. For this reason, the support shafts 16 of each pair intersect with each other in an inclined state so as to open between their tips. As shown in FIGS. 10, 14 and 15, each support shaft 16 has a large diameter portion 66 and a small diameter portion 67, and a tapered tapered portion 68 is formed at one end of the large diameter portion 66. At the same time, a flange 69 is formed at the other end of the large diameter portion 66. A small diameter stepped engaging portion 70 is recessed in the large diameter portion 66 near the tapered portion 68. At the tip of the small diameter portion 67, a stepped holding portion 71 having a further smaller diameter is formed in a concave shape. The portion of the large-diameter portion 66 excluding the flange-side end is a flat portion 72 having a D-cut shape cut off on the diameter line of the support shaft 16. An O (O) ring 73 is fitted to the large diameter portion 66 at a position in contact with the flange 69.

  As shown in FIG. 10, the support shaft 16 is accommodated in a state where the flat portion 72 is located on the open side of the shaft support portions 61 and 62. Further, the claw portion 64 of the retaining portion 65 is retained by the retaining portion 70 under the elasticity of the retaining portion 65 and retained in the shaft support portions 61 and 62 in a retaining state. I have. When a pulling force is applied to the support shaft 16 from the shaft support portions 61 and 62, when the pullout torque is equal to or more than a predetermined value, the claw portion 64 is broken and the support shaft 16 can be pulled out. . This predetermined value of the pullout torque is defined as a first torque. The support shafts 16 are arranged so as to intersect with the plane portions 72 facing each other, and the axes of the support shafts 16 are arranged on the same plane. Therefore, as shown in FIG. 3, the rotating body 18 is also arranged on the same plane α. As shown in FIG. 6, each pair of the support shaft 16 and the rotating body 18 are located on the axis の of the opening inclination angle θ1, and two inner adjacent two of the pair of the support shaft 16 and the rotating body 18 are provided. The support shaft 16 and the rotating body 18 are located on the axis の of the tapered inclination angle θ2.

  As shown in FIGS. 6 and 7, in the present embodiment, the opening inclination angle θ1 of the axis の of each of the pair of left and right support shafts 16 and the rotating body 18 is 70.5 degrees. In each pair of the support shaft 16 and the rotating body 18, the tapered inclination angle θ2 of the axis 軸 of the adjacent inner supporting shaft 16 and the rotating body 18 is 95.6 degrees. The large-diameter portion 66 of the support shaft 16 is inserted through the insertion hole 17 of the cover member 15 from the outside, and the flange 69 and the small-diameter portion 67 are located outside the end face portion 52. For this reason, the flange 69 and the O-ring 73 are located on the outer side surface of the end face portion 52 of the cover member 15, and the flange 69 and the O-ring 73 allow the cover member 15 to move away from the step portion 28 of the cover member 13. Movement is suppressed. The O-ring 73 is made of a silicone resin in order to obtain easy deformation and strength, but may be made of NBR (nitrile rubber), PP, or the like.

  As shown in FIGS. 18 and 19, the flange 69 of each support shaft 16 is disposed along the curve on the end surface 52 of the cover member 15, and the flanges of the two support shafts 16 on both outer sides in the arrangement direction are provided. 69 is located outside the flange 69 of the two inner support shafts 16. Therefore, the two rotators 18 located on both outer sides in the arrangement direction protrude forward, and the two rotators 18 located in the center are located on the rear side, which is the rear, as shown in FIG. In the present embodiment, the difference ε between the front and rear heights of the rotating body 18 is 4.0 mm (millimeter). In the present embodiment, the interval δ between each pair of rotating bodies 18 is 5.0 mm, and the interval γ between two adjacent rotating bodies 18 on the back side of each pair of rotating bodies 18 is , 8.4 mm.

  As shown in FIGS. 15 and 18, a bearing 74 having a substantially quadrangular prism shape is rotatably supported on the small-diameter portion 67, and this bearing 74 is fitted into the holding portion 71 of the support shaft 16. It is retained by a ring-shaped stop ring 75. The bearing 74 is made of POM as a material suitable for rotation, but may be made of ABS, PC, PE, PBT, PA6, PP (polypropylene) or the like. The retaining ring 75 is made of POM in order to obtain tensile strength and corrosion resistance, but may be made of ABS, PC, PE, PBT, PA6, PP (polypropylene) or the like. The rotating body 18 is fitted on the bearing 74. Therefore, the rotating body 18 is rotated on the support shaft 16 together with the bearing 74. The bearing 74 is made of a synthetic resin material having a small friction coefficient. The outer diameter of the retaining ring 75 is substantially equal to the inner diameter of a portion of the rotating body 18 facing the retaining ring 75 in the inner cavity 84. In other words, when the stop ring 75 is to be expanded in a state where the rotating body 18 is fitted on the bearing 74, the stop ring 75 interferes with the inner diameter surface of the lumen 84.

  As shown in FIGS. 16 to 18, positioning protrusions 78 and 79 are formed at both ends in the axial direction of both sides of the bearing 74. Among the positioning protrusions 78, 79, the positioning protrusion 78 on the flange 69 side is higher than the positioning protrusion 79 on the stop ring 75 side. Then, the higher positioning ridge 78 is engaged with the positioning groove 80 inside the rotating body 18, and the bearing 74 and the rotating body 18 are positioned. The lower positioning ridge 79 is pressed against the inner surface of the rotating body 18 to prevent rattling between the rotating body 18 and the bearing 74.

  An opening 82 is formed in substantially a half of the peripheral wall of the bearing 74. A protruding piece 77 is projected from the axial edge of the open portion 82 toward the inside of the open portion 82, and a claw portion having a guide slope 87 for guiding the attachment of the rotating body 18 at the tip thereof. 76 are formed. The claw portion 76 is engaged with a concave portion 86 inside the rotating body 18 to prevent the rotating body 18 from being pulled out. The claw portion 76 constitutes a vulnerable portion against destruction, and when a pullout torque of a predetermined value or more acts on the rotating body 18 and the support shaft 16 from the rotating body 18, the claw portion 76 is broken, and The body 18 can be withdrawn. This pulling torque is referred to as a second torque, and the second torque is a value lower than the first torque for pulling out the support shaft 16. Further, when the claw portion 76 is broken by the pullout torque, the shape and size of the claw portion 76 are set so that a residual protrusion 89 indicated by a two-dot chain line in FIG. Have been.

The beauty device configured as described above is assembled in the following procedure.
That is, as shown in FIGS. 6 and 7, the holder member 14 is fitted into the first concave portion 22 of the cassette body 11 of the cuff member 13, and the convex portion 31 is fitted into the second concave portion 23. At the same time, the first to fourth engagement portions 32, 33, 34, 35, and 37 are engaged with the peripheral edge of the main body 11. As a result, the holder member 14 is positioned with respect to the Casser member 13. Then, in this state, the cap member 13 and the holder member 14 are fixed by the tap screw 42. Next, the cover member 15 is assembled to the cass member 13 so as to cover the cass member 13 and the holder member 14. Is engaged with the step portion 28 of the cuff member 13, and the cover member 15 is positioned.

  On the other hand, as shown in FIGS. 15 and 18, an O-ring 73 is attached to the flange 69 of the large-diameter portion 66 of the support shaft 16. Further, the bearing 74 is attached to the small-diameter portion 67 of the support shaft 16, and the retaining ring 75 is attached to the holding portion 71 of the small-diameter portion 67, so that the bearing 74 is held. Further, the rotating body 18 is fitted around the outer periphery of the bearing 74. The attachment of the O-ring 73 and the attachment of the bearing 74 may be performed one after another. In the externally fitted state of the bearing 74, as shown in FIG. 19, the bearing 74 and the rotating body 18 are positioned by fitting the positioning ridge 78 and the positioning groove 80. Further, the rotating body 18 is fixed to the bearing 74 by the engagement between the claw portion 76 and the concave portion 86. Thus, an assembly of the support shaft 16, the bearing 74, and the rotating body 18 is configured.

  Then, the support shaft 16 to which the rotating body 18 is attached is inserted into the shaft support portions 61 and 62 of the holder member 14 from the insertion hole 17 of the cover member 15. With the insertion of the support shaft 16 into the shaft support portions 61 and 62, the taper portion 68 of the support shaft 16 engages with the slope 87 of the claw portion 64 of the retaining portion 65 to make the retaining portion 65 elastic. After retreating in opposition, the claw portion 64 is hooked on the hooking portion 70 of the support shaft 16, and the support shaft 16 is prevented from being pulled out. In this case, since the inner end positions of the shaft support portions 61 and 62 that define the insertion depth of the support shaft 16 in the axial direction are located at the back side where the inner ends of the support shaft 16 do not come into contact with the distal end of the support shaft 16 in the inserted state. In the state in which is accommodated in the shaft support portions 61 and 62, a clearance is formed between the inner ends of the shaft support portions 61 and 62 and the tip of the support shaft 16. For this reason, the support shaft 16 is pushed in until the claw portion 64 is properly hooked on the hook portion 70, and the support shaft 16 can be properly hooked by the hook portion 64.

  In this case, since the shaft supporting portions 61 and 62 have a depth that accommodates the radial half of each pair of the supporting shafts 16, the supporting shafts 16 are arranged so that the flat portions 72 of the supporting shafts 16 are in contact with each other. The direction of the direction about the axis of is set. In this way, the flat portions 72 of the support shaft 16 are joined together, and the rotation of the support shaft 16 is prevented. In this state, the engagement of the O-ring 73 with the end surface 52 of the cover member 15 prevents the support shaft 16 from moving to the depths of the shaft support portions 61 and 62. Further, the engagement between the claw portion 64 and the latch portion 70 prevents the support shaft 16 from moving in the withdrawing direction from the shaft support portions 61 and 62. Accordingly, the rotating bodies 18 are arranged in the positional relationship shown in FIG. 6, and the backlash of the support shaft 16 in the axial direction can be prevented.

The beauty device of the embodiment can be assembled as described above.
The beauty device of the present embodiment is used as follows.
As shown in FIGS. 2, 21 and 22, this cosmetic device is normally gripped by the user's thumb, index finger and middle finger. Then, the surface portion of the face is mainly rubbed by the Cassa portion 12, and the Cassa massage is performed. In this case, as shown in FIG. 20, the bulging part 19 of the cass part 12 can massage a part of the face such as the cheek and the outer corner of the eyes. In addition, the protruding portion such as the chin can be massaged by the concave portion 20 of the casser portion 12.

  Furthermore, as shown in FIG. 21 and FIG. 22, a surface portion such as a face can be rolled and massaged by the rotating body 18. In this case, of the four rotating bodies 18, two rotating bodies 18 located on both outer sides protrude forward, and two inner rotating bodies 18 are located on the back side. For this reason, the four rotating bodies 18 can be simultaneously involved in the rolling massage along the bulge of the surface such as the face. In addition, by simultaneously applying the rotating body 18 and the one bulging portion 19 at the end of the array to a surface portion such as a face, the rolling massage by the rotating body 18 and the cassama surge by the bulging portion 19 can be performed simultaneously.

  At the time of this rolling massage, two pairs of left and right rotating bodies 18 are supported on a support shaft 16 which is arranged to be inclined so as to extend forward. For this reason, if the beauty device is moved in the rolling direction of the rotating body 18, as shown by a two-dot chain line in FIG. Is pressed, and the skin between each pair of rotating bodies 18 is pulled. As the rotator 18 rolls in the reverse direction, two pairs of rotators 18 simultaneously pick up two portions of the surface portion 100 such as a face, as indicated by the two-dot chain line in FIG.

  On the other hand, of the two pairs of rotating bodies 18 on the left and right, two adjacent rotating bodies 18 located on the inner side are supported by the support shaft 16 which is inclined and arranged in a tapered shape. Therefore, if the cosmetic device is moved and inclined in the rolling direction of the rotating body 18 in the same manner as described above, as shown by a two-dot chain line in FIG. The face portion of the face is picked up by the two pairs of rotating bodies 18. Further, as the rotating body 18 rolls in the opposite direction, as shown by a two-dot chain line in FIG. 2, the skin between the two rotating bodies 18 is pressed and pulled by the two adjacent rotating bodies 18.

  Therefore, if the beauty device is reciprocated, the pick-up, pressing and pulling can be performed simultaneously and alternately by each pair of rotating bodies 18 and two adjacent rotating bodies 18, The body surface portion 100 can be continuously and evenly massaged by the rotating body 18, and an effective cosmetic effect can be obtained.

This embodiment has the following effects.
(1) The cosmetic device is provided with a holder member 14 for supporting the rotating body 18, a cass member 13 having a cass part 12 for the cass, and a cover member 15 having an appearance function. Therefore, the user can freely select and execute the massaging of the massaging by the massaging unit 12, the rolling massage by the rotating body 18, and the massaging of the massaging by the massaging unit 12 and the rolling massage by the rotating body 18 as necessary. Thus, a beauty massage suitable for the user can be performed. That is, as shown by the two-dot chain line in FIG. 20, the rubbing massage can be performed under the eyes and the outer corners of the eyes, and the rolling massage can be performed by the rotating body 18, and the rubbing can be further performed. The effective massage effect can be obtained by the simultaneous massage of and rolling. In addition, since the beauty device main body 10 is configured by the holder member 14, the cass member 13 and the cover member 15, the number of parts can be reduced. Therefore, the configuration can be simplified, and the assembly of the beauty device becomes easy.

  (2) The cosmetic device body 10 is composed of a cass member 13 having a cass part 12, a holder member 14 for supporting the rotating body 18, and a cover member 15 covering the cass member 13 and the holder member 14. Therefore, a low-friction coefficient suitable for massaging massage can be selected as the mass member 13, a high-toughness material suitable for supporting the rotating body 18 can be selected as the holder member 14, and decoration and use can be selected as the cover member 15. Of a material suitable for gripping can be selected. Therefore, it is possible to avoid the manufacturing member and the design member from being restricted as the cassard member 13, the holder member 14, and the cover member 15. For this reason, it can be set as a high-performance and excellent appearance as a cosmetic device.

  (3) Since metal plating is applied to the cass part 12, the coefficient of friction of the surface of the cass part 12 becomes small, and the cass part 12 becomes slippery. Thus, by reducing the friction coefficient of the cass part 12, the skin is hardly pulled at the time of cass massage of the body surface part 100, and it can be used comfortably.

  (4) The parts other than the cass part 12 and the rotating body 18 used for massage are covered by the both side parts 51 and the end parts 52 of the cover member 15, and the support shaft 16 and the holder member 14 are concealed without being exposed. As a result, the cosmetic device as a whole can have an excellent appearance. Further, since the cover member 15 can be made of a different material and color from those of the casing member 13 and the holder member 14, various decorations can be made.

(5) Since the rotating body 18 is spherical, the body surface is pressed in a state close to point contact, and effective massage can be performed with strong pressure.
(6) Since a total of four rotating bodies 18 in two pairs are supported by the support shaft 16 having a flared shape, by moving the cosmetic device in one direction, the body surface portion 100 is formed by the rotating bodies 18 of each pair. Are picked up and moved in the other direction, so that the two portions of the body surface portion 100 are pulled. In addition, two of the four rotating bodies 18 that are adjacent to each other at the back are supported by the tapered support shaft 16, so that the beauty apparatus is moved in one direction to be adjacent to the rotating body 18. The body surface portion 100 is picked up by the pair of rotating bodies 18 at a timing opposite to that of each pair of rotating bodies 18 and is pulled by being moved in the other direction. As described above, the body surface portion 100 is subjected to the picking up and pulling actions alternately and at the opposite timing, so that an effective beauty massage can be performed. When the body surface portion 100 is picked up and pulled, pores in the skin are widened, and dirt and waste products in the pores can be easily taken out from the pores.

  (7) The holder member 14 is attached to the Casser main body 11 of the Casser member 13 in a positioning state, and the cover member 15 is attached to the step 28 of the Casser member 13 in a positioning state. As described above, since the holder member 14 and the cover member 15 are assembled with reference to the Casser member 13, high assembly accuracy can be obtained and the assembly can be easily performed.

  (8) The cover member 15 is integrally formed by a pair of side surface portions 51 that cover the portion of the Casser member 13 excluding the Casser portion 12 and the end surface portions 52 that are located between the both side surface portions 51 and are integral with the both side surface portions 51. ing. Therefore, the cover member 15 can be configured by one component, and the configuration of the cover member 15 can be simplified. Further, in a state where the cover member 15 is positioned by the step portion 28 of the Casser member 13, the support shaft 16 is inserted into the insertion hole 17, and the end surface of the holder member 14 is located on the inner surface of the end surface portion 52, An O-ring 73 on the shaft 16 is located on the outer surface of the end face portion 52. In this manner, since the end surface portion 52 of the cover member 15 is held by the holder member 14, the Casser member 13, and the O-ring 73, it is not necessary to screw the cover member 15 to the Casser member 13 and the holder member 14. Become. Therefore, assembling of the cover member 15 is facilitated, and the appearance is improved because there is no screw. Also, when using the cosmetic device, the head of the screw does not hit the body surface portion 100, so that a good feeling of use can be obtained.

  (9) Because the cover member 15 has the both side surfaces 51 and the end surface 52 integrally formed, for example, compared to a configuration in which a plurality of parts in which the both side surfaces 51 and the end surface 52 are separate are combined. Also, the assembly of the cover member 15 is facilitated. In addition, since there is no joint between the parts, not only the appearance is excellent, but also the foreign matter and the residue of cosmetics are not clogged at the joint, the cleanliness can be maintained, and the appearance can be prevented from deteriorating. .

  (10) Since the beauty device is formed in a symmetrical shape and the rotating body 18 is arranged on the same plane α, there is no directionality in the left and right directions when using the beauty device. Therefore, the beauty device can be used in the same manner in either direction without being constrained to the left and right directions and the front and back directions, and the device is easy to use.

  (11) Since the depressions 30 are formed in the center portions of the outer side surfaces of the both side surface portions 51 of the cover member 15, respectively, when the cosmetic device is gripped with a fingertip, it can be stably gripped. Therefore, the rubbing massage by the cass part 12 and the rolling massage by the rotating body 18 can be easily and appropriately performed.

  (12) A convex curved surface swelling in an arc shape is formed on the outer surface of the side surface portion 51 of the cover member 15. Therefore, in a state in which the beauty device is grasped with a fingertip, it is possible to freely and delicately change the contact angle of the cass part 12 and the rotating body 18 with the skin by the movement of the fingertip without much movement of the wrist. It becomes easy to use.

  (13) As shown by a two-dot chain line in FIG. 20, one bulging portion 19 of the cass part 12 and one rotating body 18 at the end of the array can be simultaneously applied to the skin, so that rubbing massage and rolling are performed. Massage can be performed simultaneously, and efficient massage can be performed. For example, by using the rotating body 18 for the thin eye area of the skin and the cass part 12 for the thick cheek, it is possible to simultaneously massage parts having different skin thicknesses with appropriate strength. Becomes possible. Moreover, in this case, as shown in FIG. 2, the boundary 29 between the Casser portion 12 and the cover member 15 is inside the line β connecting the top of the Casser portion 12 and the outer peripheral surface of the rotating body 18 at the array end. , The boundary 29 can be prevented from contacting the skin, and a good feeling of use without discomfort can be maintained. Further, as shown by a two-dot chain line in FIG. 2, the rotating body 18 and the side surface 51 of the cover member 15 can be simultaneously applied to the skin of the body surface 100, so that rolling massage and rubbing massage with a large area can be performed. Can be performed simultaneously, and an effective massage can be performed.

  (14) Since the four rotating bodies 18 are arranged on the same plane α, the picking up of the surface by each pair of rotating bodies 18 can be performed naturally and comfortably. On the other hand, when the rotating body 18 is not arranged on the same plane α, a force in the twisting direction acts on picking up and pulling the rotating body 18, so that the usability may be reduced.

  (15) Of the four rotators 18, the inner two rotators 18 are arranged at the back, so that a convex portion such as a face such as a jaw can be widened by the four rotators 18. Massage at the same time.

  (16) Since the support shafts 16 of each pair intersect, the support shafts 16 can be lengthened to prevent backlash of the support shafts 16 and the angles θ1 and θ2 between the shafts are set with high accuracy. it can. Therefore, it is possible to improve the shaft strength and shaft accuracy to obtain a feeling of use and a sense of quality. In addition, since each pair of support shafts 16 that penetrate the insertion hole 17 of the cover member 15 is inclined, and in addition, each pair of support shafts 16 intersect, the cover member 15 is It is held without being displaced or detached from the member 13. Therefore, the mounting strength of the cover member 15 can be increased without providing fixing means such as screws.

  (17) Since the D-cut flat portions 72 are formed on the support shafts 16 and the pair of support shafts 16 make the flat portions 72 contact each other, the thickness of the cosmetic device can be reduced. Further, the floating of the support shaft 16 on the mating side from the shaft support portions 61 and 62 can be suppressed by the flat surface portion 72 that is in contact with the flat surface portion. 16 can be simplified. Further, a closed annular configuration in the form of a hole for supporting the support shaft 16 on the holder member 14 becomes unnecessary, and the die removal in the molding of the holder member 14 becomes easy. As a result, molding of the mold is simplified. Further, the rotation of the support shaft 16 is prevented by the contact of the flat portion 72. For this reason, it is possible to prevent abrasion of the portions of the shaft support portions 61 and 62 of the holder member 14 due to the rotation of the support shaft 16, and as a result, it is possible to prevent the backlash of the support shaft 16 and maintain a high-grade feeling of use.

  (18) A taper portion 68 is formed at the tip of the support shaft 16, and an inclined surface 87 is provided on the claw portion 64 on the holder member 14 side, so that the support shaft 16 is attached to the shaft support portions 61 and 62 at the end of assembling the cosmetic device as a whole. The support shaft 16 is configured to be fixed by being inserted and by the hook portion 70 and the hook portion 64 being hooked. That is, when assembling the rotating body 18, the rotating body 18 is assembled to the support shaft 16 via the bearing 74, and the support shaft 16 in that state is inserted into the shaft support portion 61, through the insertion hole 17 of the cover member 15. 62 can be inserted. Of course, the support shaft 16 may be assembled to the holder member 14 alone, and then the rotating body 18 may be assembled to the support shaft 16. In this case, since the tapered portion 68 is formed at the end of the support shaft 16, the end of the support shaft 16 does not interfere with the insertion hole 17 and the entrances of the shaft support portions 61 and 62, and the support shaft 16 is supported by the shaft. It can be smoothly inserted into the parts 61 and 62. When the support shaft 16 is housed in the shaft supports 61 and 62, a clearance is formed between the inner ends of the shaft supports 61 and 62 and the tip of the support shaft 16. Therefore, when the support shaft 16 reaches a predetermined position, the claw portions 64 are compressed while the compression deformation of the O-ring 73 between the end surface portion 52 of the cover member 15 and the flange 69 of the support shaft 16 and the curvature deformation of the end surface portion 52 are caused. Is retracted and latched in the latch 70 in the fitted state. When the claw portion 64 is hooked on the hooking portion 70, the compression deformation of the O-ring 73 and the curved deformation of the end face portion 52 are restored, and the support shaft 16 is firmly fixed without rattling. Therefore, the support shaft 16 can be easily assembled. After the assembly, the support shaft 16 does not come off, and the rotating body 18 can be brought into contact with the skin to perform a massage by a motion according to the user's intention.

  (19) A bearing 74 made of a synthetic resin material having a small coefficient of friction is rotatably fitted to the support shaft 16, and the bearing 74 is retained by the support shaft 16 in a retaining state by a retaining ring 75 made of synthetic resin. I have. Therefore, a smooth rotation without rattling can be obtained as the rotating body 18, and a cosmetic device excellent in usability can be realized.

  (20) For example, in the case where the rotation of the rotating body 18 is poorly caused by the bearing 74, a force is applied to the rotating body 18 in the axial direction of the support shaft 16 to rotate by the second torque. When the body 18 is to be pulled out from the support shaft 16, the protruding piece 77 is broken at a portion of the claw portion 76 as a weak portion of the bearing 74. That is, when the rotating body 18 is externally fitted to the bearing 74 on the support shaft 16, the outer diameter of the retaining ring 75 is substantially equal to the inner diameter of the inner cavity 84 of the rotating body 18. In this case, the outer peripheral surface of the retaining ring 75 interferes with the inner peripheral surface of the inner cavity 84. Therefore, the bearing 74 held by the retaining ring 75 cannot come off the support shaft 16. Therefore, the pulling force with respect to the rotating body 18 is concentrated on the claw portion 76, and the claw portion 76 is destroyed. As a result, the rotating body 18 can be detached from the support shaft 16 alone with the bearing 74 left on the support shaft 16, and the bearing 74 can be easily replaced. For this reason, the bearing 74 does not remain in the rotating body 18, and the bearing 74 remains attached to the small-diameter portion 67 of the support shaft 16. On the other hand, if the bearing 74 remains in the rotating body 18, it is difficult to reuse the rotating body 18. In other words, in such a case, it is necessary to remove the bearing 74 from the inside of the rotating body 18 in order to reuse the rotating body 18. However, in the configuration of the present embodiment, such work is omitted. be able to.

  (21) When the rotating body 18 is detached from the support shaft 16, the claw portion 76 of the bearing 74 is broken, but a small residual protrusion 89 is formed at the claw portion 76 at the tip of the protruding piece 77. Therefore, if there is any need to reassemble the rotating body 18 after the rotating body 18 is detached, the rotating body 18 in the reassembled state can be held by the residual protrusion 89, so that the claw portion 76 can be compared with before the fracture. Then, although there is some backlash, a rolling massage can be performed.

  (22) If an assembling error occurs in which the O-ring 73 is not attached to the support shaft 16, the support shaft 16 is pulled out of the holder member 14 to attach the O-ring 73. In this case, the claw portion 76 of the projection 77 of the holder member 14 is broken, and the support shaft 16 can be pulled out. Therefore, damage to the expensive support shaft 16 made of metal can be avoided. If the holder member 14 is replaced with a new one, the support shaft 16 can be reused.

  (23) Since the support shaft 16 is made of stainless steel, it has excellent corrosion resistance and high toughness. Therefore, it is possible to prevent the support shaft 16 from being corroded by the cosmetic solvent or the surface from being oxidized. As a result, the smooth rotation of the bearing 74 supported by the support shaft 16 can be maintained, and the support shaft 16 is hardly damaged or deformed, so that a good feeling of use can be maintained for a long time.
