ABSTRACT OF THE DISCLOSURE An electromagnetic clutch for an automotive air conditioning system is disclosed which includes a rotor, an electromagnetic coil, and an armature plate. A boss is secured to a drive shaft and has a wave-shaped flange which is formed on the outer surface of the boss. A front plate is disposed forwardly of the wave-shaped flange of the boss through a ring-shaped washer of elastic material. A rear plate is disposed rearwardly of the wave-shaped flange of the boss through another ring-shaped washer of elastic material. The armature plate is connected to the boss, which connects the front plate and rear plate through the washers made of elastic material, respectively, through a plurality of leaf springs. When the above electromagnetic clutch is supplied with electric current, the rotational force in the direction opposite to the rotational force of the front plate and rear plate is added to the boss. However, since the front plate and rear plate are rotatably fixed to the bogs through the ring-shaped washers made of elastic material, the drive shaft is prevented from receiving torsional resonance by the compression and deformation of the ring-shaped washers.
