Due to the presence of the upper and lower elastic pieces 160, the connecting portion 161 can be moved up and down, and the blade heads 1 each having one end attached to the supporting portion 16 thus constructed. 1 is substantially parallel to each other, so that it can be moved up and down without contacting each other, and the double-edged heads 1 and 1 can be moved up and down individually. The vertical positions of both ends in the longitudinal direction can be different. For this reason, when the double-edged heads 1, 1 are pressed against the skin, the blade heads 1, 1
Moves vertically and tilts, so that each blade head 1 changes its posture so that the contact area between each blade head 1 and the skin is always maximized.

In addition to the double-edged heads 1 and 1 being individually movable up and down as described above, the blade heads 1 can be fixed in a state where the up-down position is lowered downward. Is becoming This is the holding frame 15
Slide handle 90 on the outside of the slide
And a hook 91 protruding from the slide handle 90.
A cam member 9 that is connected to the slide frame 90 and slides on the inner surface of the holding frame 15 together with the blade head 1.
