Claims

[Claims for Utility Model Registration] (1) A rotor that is rotationally driven by a drive source such as an engine and an armature disposed opposite to this rotor are included in a magnetic circuit of an excitation coil, and the excitation coil is energized. In the electromagnetic clutch which connects the rotor and armature so as to be integrally rotatable, a plurality of leaf springs that separate the rotor and armature are attached to a hub connected to a rotating shaft of a driven device, and the leaf springs are actuated. A cylindrical damper holder is fixed to the end, and a cylindrical damper rubber is accommodated in each damper holder, while a collar whose flange part is in constant contact with the damper holder or leaf spring and whose shaft part is inserted into the cylindrical hole of the cylindrical damper rubber is used. An electromagnetic clutch having a shaft end connected to the armature, and further having a sheet made of a low friction coefficient material interposed between the contact surfaces of the armature and one or both of the leaf spring and the damper holder. (2) The electromagnetic clutch according to claim 1, wherein the seat is fitted into a counterbore formed in an armature. (3) The electromagnetic clutch according to claim 1, wherein the counterbore is bonded to a leaf spring, a damper holder, or both.
