摘要： An electromagnetic clutch capable of reducing attracting noise generated when an armature plate is attracted to the friction surface of a rotor, wherein the thickness of the projected part (32) of an elastic member (31) in the state of being compressingly held by an inner plate (26) and the armature plate (12) is increased more than the thickness of the projected part (33) of the elastic member (31) in the state of being compressively held by an outer plate (17) and the armature plate (12), whereby the volume of the projected part (32) of the elastic member (31) can be increased relative to that of the projected part (33).
