Abstract
An electromagnetic clutch mechanism includes: a driving-side rotatable body; a driven-side rotatable body; an electromagnet; a flat spring; and an elastic member that alleviates a collision impact generated between the driven-side rotatable body and the driving-side rotatable body. The driven-side rotatable body includes a recess recessed in an A direction, which is opposite to a direction that is directed from the driven-side rotatable body toward the elastic member in an axial direction. The recess functions as an urging portion that exerts an urging force to the elastic member through contact of the recess against the elastic member at the time of energizing the electromagnet. The elastic member includes an urging-force receiving portion, and the urging-force receiving portion receives the urging force from the recess through contact of the urging-force receiving portion to the recess at the time of energizing the electromagnet.
