Abstract
An electromagnetic clutch device includes an armature, a rotor, an electromagnet, and a silencing member. The armature is supported by a driving member so that the armature is movable in the axial direction and rotate integrally with the driving member. The rotor is arranged coaxially with the armature, rotate with respect to the armature and rotate integrally with an output member. The electromagnet presses the armature and the rotor against each other based on an electromagnetic attraction force generated when current is supplied through the electromagnet to be coupled with each other in the torque transmittable manner. The silencing member is provided on an outer circumferential portion of the armature to attenuate noise generated by the vibration of the armature in a state where the silencing member is out of contact with any member other than the armature.
