In order to reduce an electromagnetic clutch in an axial size, a ring-shaped leaf spring connects an armature to a hub. The leaf spring has an outer ring portion connected to the armature, an attachment portion connected to the hub and located inner than the outer ring portion, and a connecting portion for connecting the outer ring portion and the attachment portion. A plurality of rivets of the armature are disposed at the outer ring portion. An embossed portion for generating an initial deflection on the leaf spring is disposed at an intermediate portion between the rivets in the circumferential direction of the outer ring portion.
