ABSTRACT:
An electromagnetic clutch including a pulley which is rotated by an external power source through a belt or belts for selectively transmitting the rotation of the pulley to a drive shaft by electromagnetically attracting a magnetic armature supported on the drive shaft. The pulley has a magnetic annular body rotatably supported and a belt-receiving groove member of aluminum alloy formed onto the outer surface of the magnetic annular body by die casting and integrated with the magnetic annular body. The construction improves the weight, cost and simplifies the method of production of the pulley without degrading the performance and balance of the pulley.
