Abstract
A spring plate member is connected to a hub. The spring plate member includes a plate spring portion generating a resilient force to separate an armature from a rotor, and an outer ring portion, which faces the armature. An elastic member is provided between the armature and the outer ring portion for connecting the armature directly with the outer ring portion. Thus, operation noises of the electromagnetic clutch and a compressor are efficiently reduced. Further, the axial dimension of elastic member can be made much smaller than that of the conventional cylindrical elastic member.
