を介在させたことを特徴とする電磁クラツチ。 A rotor that is rotatable about a single axis and rotationally driven by an external drive source; an armature that is disposed opposite to the axial end face of the rotor and movable in a direction parallel to the single axis; and a driven armature that is movable in a direction parallel to the single axis. In an electromagnetic clutch including a leaf spring elastically supported on a shaft, and an excitation device that includes the rotor and the armature in a magnetic circuit and selectively brings the armature toward and away from the rotor, the leaf spring is coupled to the armature. An electromagnetic clutch characterized in that a damping material and a preload applying member for applying pressure to the vibration damping material are interposed in at least one of the connecting portion of the plate spring and the driven shaft.
