A rotor that is rotationally driven by a separately existing drive source via a drive belt, and a rotor that is disposed opposite to this rotor through a gap and that is connected and fixed to the rotating shaft of a driven body. In an electromagnetic clutch comprising an armature and an excitation device fixedly disposed inside the rotor and coupling the armature and rotor when energized, the rotor has an annular shape with a V-groove in contact with a drive belt. a rotor core rotatably held in the housing of the driven body by a bearing, and an annular ring press-fitted between the inner periphery of the pulley ring and the outer periphery of the rotor core so as to apply a compressive strain of 15% to 30%. The rotor core is characterized in that a rib having a diameter larger than the inner diameter of the pulley ring is disposed circumferentially on the friction surface side of the cylindrical outer surface of the rotor core that faces the armature. electromagnetic clutch. 2. The electromagnetic clutch according to claim 1, characterized in that a rib having a width smaller than the V-groove width is provided on the inner circumference of the pulley ring.
