ABSTRACT:
An electromagnetic clutch is disclosed that 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 therebetween. A holder plate is fixed on an outer axial end surface of the armature plate and is formed with a triangularly axially extending flange. The radial flange portion of the hub is also formed with a second axially extending flange corresponding to the first flange. The first and second axially extending flanges are formed of a similar configuration and face one another with a radial gap. An elastic member is disposed in the radial gap to ease the impact force created when the clutch is engaged.
