Description of the Related Art Conventionally, in a reciprocating electric shaver in which an inner blade 2 can be attached to and detached from a driver 1 and a drive is transmitted, a joint portion 22 is formed at a lower portion of an inner blade base 24 as shown in FIG. The spherical driving force transmitted portion 21a is formed in the center of the joint portion 22.
Are formed. A substantially U-shaped driving force transmitting portion 12a having an open top is formed on the upper portion of the driver 1.
The inner blade 2 can be fitted so as to hold the spherical driving force transmitted portion 21a. A hook 13 is formed at the upper end of the driving force transmitting portion 12a to prevent the driving force transmitted portion 21a from coming off. The driving force transmitting portion 12a is elastically deformable, and can be bent outward (direction of transmitting driving force: vibration direction) when the driving force transmitted portion 21a is attached or detached. As a result, when the driver element 1 reciprocates, the inner blade 2 can reciprocate through the driving force transmitting portion 12a and the driving force transmitted portion 21a. Further, since the driving force transmitted portion 21a of the inner blade 2 is spherical, the driving force is transmitted and the driving force transmitted portion 2 is transmitted.
The inner blade 2 can be swung (tilted) around the center 1a.

という問題があった。Here, the inner blade 2 is pushed up by the push-up spring 15 in the driver 1 so that the inner blade 2 works to push up the outer blade (not shown). When the outer blade is detached for cleaning, etc., the inner blade 2 moves upward by the action of the push-up spring 15. At this time, the spherical driving force transmitted portion 21a of the inner blade 2 also moves upward along the concave portion in the driver 1, but the driving force transmitting point is
Since it only moves on the wall surface of the recess, if the driver 1 is driven to wash the inner blade 2 with water in this state,
There was a problem that abrasion powder generated by the vibration of the inner blade 2 was accumulated at the driving force transmission point, which hinders sliding. Further, when the inner blade 2 is attached to the driver element 1, the spherical driving force transmitted portion 21a may receive a force on the recess wall surface in an oblique direction. At that time, the wall surface is abnormally worn and the driving force transmission point Wear powder accumulates on the inner blade 2
There is a problem in that sliding of the inner blade 2 becomes worse due to seizure between the inner blade 2 and the like.
