Abstract

An electromagnetic clutch () capable of connecting and disconnecting a driving power source and a rotary shaft () includes a rotor () rotated by the driving power source, and an armature () capable of being attracted to the rotor () by electromagnetic force to produce a transmission force transmitted from the rotor () to the rotary shaft (). The electromagnetic clutch () further includes leaf springs () urging the armature () in such a direction as to separate the armature from the rotor (). The leaf springs () each assume an orientation such that a boost force assisting the attractive force acting upon the armature () is produced based on the transmission force when the armature () is attracted to the rotor ().
