ABSTRACT:
An electromagnetic clutch includes a rotor assembly constituted by a pulley portion and a rotor portion. The pulley portion has a pulley portion on an outer circumferential side, is axially supported on a driven shaft to be rotatable, and is designed to receive a driving force from a driving shaft. The rotor portion has an armature on a side of the driving shaft. The armature is selectively friction-engaged by magnetic attraction. The rotor portion of the rotor assembly is formed by casting to have an uneven surface shape constituted by a plurality of projections on its outer circumferential surface. The synthetic resin pulley portion is integrally coupled to the outer circumferential surface of the rotor portion by insert molding.
