Description
次いで、第４工程に於いて、前記第三中間素材の外周面の軸方向他端部に、例えば、切削加工、転造加工、又はプレス成型を施す事により、前記小径部４８（雄セレーション５１）と、前記段部４９とを形成する。この様にして第四中間素材を得る。
Next, in the fourth step, the other end portion in the axial direction of the outer peripheral surface of the third intermediate material is subjected to, for example, cutting, rolling, or press molding, so that the small diameter portion 48 ( male serration 51). ) And the stepped portion 49. In this way, a fourth intermediate material is obtained.
次いで、第６工程に於いて、この第五中間素材のうちの前記雄スプライン部８ｂに相当する部分の内周面の軸方向一端部から軸方向中間部にかけての部分に切削加工を施す事により、前記大径孔部４２（前記薄肉部４５）を形成する。一方、前記第五中間素材のうちの前記雄スプライン部８ｂに相当する部分の内周面の軸方向中間部から軸方向他端部にかけての部分は、そのまま前記中径孔部４３とする。 Next, in the sixth step, by cutting a portion of the fifth intermediate material corresponding to the male spline portion 8b from one end portion in the axial direction of the inner peripheral surface to the intermediate portion in the axial direction. The large diameter hole portion 42 (the thin portion 45) is formed. On the other hand, a portion of the fifth intermediate material corresponding to the male spline portion 8b from the intermediate portion in the axial direction to the other end portion in the axial direction is used as the medium diameter hole portion 43 as it is.
