Abstract
In a clutch mechanism formed by adhering a friction member to a face of one of a pair of rotating elements with an adhesive member and arranged to bring the surface of the other of the pair of rotating elements into pressed contact with the friction member by an urging member, a recessed part is formed in the face of the one of the rotating elements to which the friction member is adhered, so as to accumulate and retain pressure sensitive adhesive seeping from the adhesive member.
