CA 2027442
An electromagnetic clutch is disclosed which includes a clutch rotor having a first friction surface and an annular armature plate having a second friction surface. The first friction surface and the second friction surface face each other. A friction member is made of nonmagnetic material and is fixedly disposed within a second groove formed at the second friction surface of the annular armature plate. A first end surface of the friction member projects with respect to the second friction surface of the annular armature plate. The first friction surface of the clutch rotor is provided with a first annular groove to receive the projecting portion of the friction mem- ber. Therefore, the depth of the second groove becomes smaller. Consequently, a reduction of the number of magnetic lines of flux which radially penetrate through an annular portion of the annular armature plate at the location of the second groove is prevented. Thus, the magnetic attraction between the annular armature plate and the clutch rotor is increased without increasing the weight of the electromagnetic clutch.
