Abstract

In an electromagnetic clutch having a pulley 10 which is rotated by an external driving power source through a belt or belts for selectively transmitting the rotation of the pulley to a drive shaft 5 by electromagnetically attracting a magnetic armature 7 supported on the drive shaft 5, the pulley comprises a magnetic annular body 101 rotatably supported and a belt- receiving groove member 102 of aluminium alloy formed onto the outer surface of the magnetic annular body 101 by die-casting and integrated with the magnetic annular body, in order to improve the weight, the cost and the producing method of the pulley 10 without degrading the performance and the balance of the pulley. <IMAGE>
