Electric shaver

摘要

A support arm that is rockably supported on one end of a grip portion and projects from the one end is provided. Both ends of a blade head are supported by the support arm such that the blade head can rock around an axis extending along a reciprocating direction of an inner blade, and an axial direction of the rocking motion of the support arm with respect to the grip portion is set in a direction intersecting with the reciprocating direction of the inner blade. This configuration achieves an electric shaver capable of increasing the movable range of the blade head while preventing a main body from increasing in size.
