ABSTRACT:
An electromagnetic clutch for an automotive air conditioning system is disclosed. The electromagnetic clutch includes a rotor, an electromagnetic coil, and an armature plate. A hub is secured to a drive shaft and has a radially extending flange portion which is provided with a plurality of pairs of first projecting portions. A damper plate is disposed forwardly of the armature plate so as to be connected with the armature plate through a plurality of leaf springs and is provided with a plurality of second projecting portions and longitudinal holes on the axial end surface thereof. Each pair of the first projecting portions can be disposed within each pair of the second projecting portions with a gap therebetween that may accommodate one of a plurality of elastic members. A stopper plate is disposed on the axial end surface of the damper plate and may be radially moved within the range of the longitudinal holes which are provided therein. Therefore, torsional resonance, shock and vibration are eased by the principally compressive deformation of the elastic member which is enclosed within the space between the first and second projecting portions.
