The hair removal device shown in FIG. 1 has a hair removal block 2 disposed at the upper end of a main body 1 having a motor 11 built therein. The rotation of the motor 11 in the main body 1 is transmitted to a rotating body 3 having a face gear 31 integrally formed on the lower surface via a reduction gear train 12 and swings via a link mechanism (not shown). The power is transmitted to the gear 13.

On the other hand, the epilation block 2 is mounted on the support 20 so as to swingably support the middle of the plurality of disks 21 in the vertical direction, and is slidable with respect to the support 20 in the axial direction. The slide levers 22 and 23 are provided, and every other disk 21 is
Then, the remaining disk 21 is engaged with the slide lever 23. When the slide levers 21 and 23 move in opposite directions, each disk 21 opens and closes with the support 20.

The support 20 is supported on the frame 15 by a shaft 25 and has a gear 26 at one end for meshing with the swing gear 13. 20 swings around an axis 25. This swinging operation is linked to the opening / closing operation described above, and the hair held by the opening / closing operation of the disk 21 can be pulled out by the swinging operation.

A pair of slide levers 22 and 23 in the epilation block 2 are driven by a pair of movable levers 4 and 4 having one ends engaged with the rotating body 3. That is, as shown in FIGS. 3 and 4, the cam portion 3 as an annular groove having a radius different from place to place is provided on the upper surface of the rotating body 3.

When the rotating body 3 rotates, each of the movable levers 4 and 4 swings around the support shafts 16 and 16 which are in the axial direction orthogonal to the axial direction of the rotating body 3. As a result, the slide levers 22 and 23 reciprocate. At this time, although the movement of the movable lever 4 is oscillating about the support shaft 16, since the axial direction of the support shaft 16 is parallel to the direction of the rotation axis of the rotating body 3, the cam portion 30 The state where the side wall of the roller 41 and the outer peripheral surface of the roller 41 are in line contact is always maintained. In addition, since the line connecting the contact portion and the rotation center of the rotating body 3 is the same as the reciprocating direction of the slide levers 22, 23, the reciprocating drive of the slide levers 22, 23 is ensured.

As shown in FIGS. 5 and 6, the supporting shafts 16 and 1 extend in a direction perpendicular to the direction of the rotation axis of the rotating body 3.
6, the movable levers 4, 4 are slidably engaged with the support shaft 16, and the movable lever 4 is reciprocally slid in the axial direction of the support shaft 16 with the rotation of the rotating body 3. Good. Also in this case, the state where the side wall of the cam portion 30 and the outer peripheral surface of the roller 41 are in line contact with each other is always maintained.
