Claims

[Scope of utility model registration request]

A rotor rotationally driven by a drive source, an armature installed opposite to the friction surface of the rotor, a hub coupled to the rotating shaft of the driven device, one end coupled to the hub and the other end coupled to the rotor. a leaf spring coupled to the armature, an excitation coil that attracts and attracts the armature to the friction surface of the rotor against the spring force of the leaf spring, and the hub located on the opposite friction surface side of the armature. a hub plate fixed to the hub plate; a cushion rubber attached to the hub plate and compressed between the armature; and a cushion rubber detachably attached to the outer peripheral end of the hub plate and compressed between the armature. An annular cushion ring made of elastic material and a serviceable electromagnetic clutch.
