ABSTRACT:
A workpiece W2 is grasped by inserting a first jig into a concave portion which is formed in a rotor forming process, and by interfitting a second jig to a convex portion which is also formed in the rotor forming process. Thereby, the workpiece W2 is firmly grasped, and a groove-forming roller can be strongly pressed into the workpiece W2. A time for forming a pulley groove is shortened, and a manufacturing cost thereof is reduced.
