CONSTITUTION:The cup like flange member 2 is forged and formed with the 1st blank material of the disk like thin steel sheet. The 2nd blank material 4 is obtained by forcibly pressing the ring member 3 formed in the ring like into the flange member 2 and fitting. Next, this 2nd blank material 4 is mounted on the supporting stand 5, and the supporting die 6 is fit into the inner side of the 2nd blank material 4. This supporting die 6 is provided with the wave shaped projecting and recessing parts 7 in the circumferential direction and its top end comes into contact with or fits with small clearance to the inner circumferential surface 2 of the flange member 2. In this state, while pressing the gear like dies 8 to the outer circumference of the 2nd blank material 4, both are rotated relatively. Therefore, the gear 9 is created with rolling on the outer circumferential part of the 2nd blank material with the dies 8.
