Therefore, when the rotating body 13 is moved on the body surface part, the body surface part 100 is pressed and picked up by the rotation of both the rotating bodies 13, as shown in FIG. Therefore, high cosmetic effects can be obtained.

Therefore, in this embodiment, the synergistic effect of the body surface part 100 being picked up as described above and being intermittently strongly pressed by the protrusions 12 makes it possible to obtain even higher cosmetic effects. .

In this beauty device, the seal rings 22, 44, and 83 prevent water from entering the base frame 14 of the handle 11, so this beauty device can be used in the bathroom without any trouble, even in the bathtub. Can be used.

According to this embodiment, there are the following effects.
(1) Since the body surface of the user of the cosmetic device is pressed and picked up by the rotating body 13 at the same time, high cosmetic effects can be obtained.

(2) In this case, due to the rotation of the rotating body 13, the body surface part is intermittently strongly pressed by the projections 12, so that even higher cosmetic effects can be obtained. Moreover, since the tip of the protrusion 12 has a ball shape, although there is moderate stimulation to the body surface, pain can be suppressed.

(3) Between the outer peripheral edge of the base frame 14 of the handle 11 and the inner peripheral edge of the opening of the second frame 16, between the cylindrical part 29 of the base frame 14 and the support shaft 38, and between the lens unit 80 and the inner edge of the through hole 78 Seal rings 22, 44, and 83 are interposed between the parts. Therefore, it is possible to prevent water from entering the base frame 14, and even if the base frame 14 accommodates electrical components such as the power generation panel 72, their functions may be inhibited by water. This can be prevented.

(4) Since the base frame 14 is boat-shaped and the wall portion of the base frame 14 is curved, the strength of the base frame 14 itself can be improved, and in turn, the strength of the handle 11 can be improved. I can do it.

It can be suppressed. Therefore, it is possible to prevent the handle 11 from being damaged or the first and second frames 15 and 16 of the handle body 20 from opening. Therefore, since the rotating body 13 can be strongly pressed against the body surface, a high massage effect can be obtained.

(7) Since the front end of the reinforcing member 19 is located at the proximal end of the support shaft 38, the force acting on the proximal end of the support shaft 38 in a direction intersecting the axial direction of the coaxial 38, that is, It is possible to resist the force that would cause the support shaft 38 to rise and damage the cylindrical portion 29 of the base frame 14, and damage to the cylindrical portion 29 and the like can be effectively avoided.

(8) By providing the reinforcing member 19 on the base frame 14 covered by the first and second frames 15 and 16, the reinforcing member 19 can be hidden, and the appearance of the handle 11 can be maintained well.

(9) By providing functional parts such as the power generation panel 72 inside the base frame 14 and providing the reinforcing member 19 on the outside of the base frame 14, the internal volume of the base frame 14 is prevented from being narrowed by the reinforcing member 19. It can be avoided. Therefore, the space within the base frame 14 can be used effectively, and functional parts can be easily assembled.

(10) By fitting the reinforcing member 19 into the recess 33 on the outer surface of the base frame 14, movement of the reinforcing member 19 can be restricted and the reinforcing member 19 can be held in a fixed position. Therefore, the reinforcing member 19 can be easily assembled, and the reinforcing member 19 can be prevented from moving in the assembled state, so that the reinforcing function can be exerted. Further, the protrusion of the reinforcing member 19 from the outer surface of the base frame 14 can be suppressed, contributing to miniaturization of the handle 11 and flexibility in design.

(11) Since the handle 11 is formed in a forward-leaning shape when viewed from the side, the handle 11 can be used in an easy-to-use position along the body surface, and an effective massage function can be obtained.

(12) Since the handle 11 is provided with the first and second covers 17 and 18 as decorative members, various effects such as a decorative effect can be obtained. That is, if the first and second covers 17 and 18 are different in appearance from the handle body 20 in terms of color, gloss, surface roughness, pattern, etc., the first and second covers 17 and 18 will affect the handle 11 and the beauty. The overall design of the vessel can be improved.

Furthermore, if the first and second covers 17 and 18 are made of wood or mixed with wood flour, the specific heat of the first and second covers 17 and 18 will be high, and the handle 11 will not be gripped. When doing so, you can feel the warmth and improve the comfort associated with the massage operation. Furthermore, if the first and second covers 17 and 18 are made of wood or mixed with wood flour as described above, the first and second covers 17 and 18 will have a higher coefficient of friction than the handle body 20 and will slip. This makes it easier to operate during massage.

If the first and second covers 17 and 18 are made of a rubber material or soft urethane material that is softer than the handle body 20, the handle 11 will fit easily in the hand and will be easy to operate during massage as described above.

If the first and second covers 17 and 18 are made of highly rigid materials such as metal, the strength of the handle body 20 can be improved. In this way, if highly rigid materials are used as the first and second covers 17 and 18, the overall strength of the handle 11 will be increased due to the synergistic effect of the first and second covers 17 and 18 and the reinforcing member 19. It can be done.

(13) As shown in FIGS. 13 to 15, undercuts are not formed at the protrusion 12 of the rotating body 13. Therefore, the outer peripheral surface of the rotating body 13 including these protrusions 12 can be easily and precisely shaped.
