Abstract

An electric power tool includes an electric motor and a rotation direction restriction mechanism. The rotation direction restriction mechanism includes an outer ring, an inner circumferential member, cam surfaces, lock members, and a protrusion (eccentric mechanism). The inner circumferential member is located on an inner circumferential side of the outer ring. The cam surfaces are recessed on an outer circumferential surface of the inner circumferential member. The inner circumferential member rotates relatively to the outer ring in a first direction and is restricted from rotating in a second direction when the lock member moves within the corresponding cam surface.
