Claims

[Claims for Utility Model Registration] 1. A clutch rotor having a pulley protruding outward from the rotor shaft end surface that is rotationally driven by an external drive source and an armature disposed opposite to the clutch rotor are disposed within the clutch rotor. In an electromagnetic clutch that transmits rotational driving force by adhering the armature to the friction surface of the clutch rotor, it is included in the magnetic circuit of the excitation coil, which is attached to the magnetic circuit of the excitation coil. An electromagnetic clutch characterized by having a notch that communicates with the outside air to discharge foreign matter. 2. The electromagnetic clutch according to claim 1, wherein the notch is a long hole extending in the circumferential direction. 3. The electromagnetic clutch according to claim 1 or 2, wherein the notch is provided by cutting and raising a part of the pulley. 4. The electromagnetic clutch according to claim 1, 2, or 3, wherein the rotor has a groove on its shaft end surface corresponding to the notch.
