An electromagnetic clutch reduces clutch operating noise at a low cost by utilizing elastic members which are suited to a spring force of a leaf spring. An approximate nonagonal leaf spring has an outer ring portion, attachment portions connected to a hub, and connecting portions. Under the outer ring portion, securing portions of an armature are disposed. First elastic members are disposed at intermediate points of the securing portions, and a second elastic member is disposed in a gap between the leaf spring and the hub along an axial direction. When actuating the electromagnetic clutch, the leaf spring compresses the second elastic member, and when stopping the electromagnetic clutch, the armature collides with the first elastic member so that an axial position of the armature is secured. |
