ABSTRACT:
An electromagnetic clutch is disclosed. The electromagnetic clutch includes a pulley and an electromagnetic mechanism. A hub is secured on a drive shaft and has a radially extending flange portion. An armature plate is concentrically disposed on the hub and faces the axial end surface of the pulley with an axial air gap. A holder plate is fixed on an axial end surface of the armature plate and is formed with an axially extending flange which has a configuration including at least one straight line. The radial flange portion of the hub is also formed with a second axially extending flange at a radial outer end portion. The first and second axially extending flanges are formed of a similar configuration and face one another with a radial gap between them. An elastic member is disposed in an inner surface of the first axial flange portion to fill the radial gap and cover the axial end surface of the radial flange portion and the second axial flange. Therefore, the hub and the armature plate are connected by the elastic member, and the impact force generated, when the electromagnetic clutch is activated, is eased by the compressive deformation of the elastic member.
