A disk material is plastic-formed to form an inner cylindrical portion of a rotor and a cover member which covers an end side of the rotor. After that, the disk material is slit inwardly from an outside thereof in a radial direction of the disk material to form an outer cylindrical portion of the rotor and a pulley corresponding portion which will be the pulley. Finally, the pulley corresponding portion is plastic-formed to form a pulley groove. Thereby, even when the location of the pulley relative to the outer cylindrical portion are different, same processes can be applied to these different type pulley integrated rotors until the disk material is slit. That is, many different type pulley integrated type rotors can be manufactured with low cost while maintaining high concentric accuracy between the pulley and the rotor.
