An extension part that extends outward in the circumferential direction from one end side of the main body, an outward flange that is formed at a right angle from the extension part, and a trapezoid that is formed on the outward flange at a predetermined pitch. In manufacturing a clutch retainer including a tooth portion, a groove in which a wavy ring or the like is fitted and held between all of the tooth portion protruding toward the inner peripheral surface of the outward flange and the extending portion is formed. As a solution means, the above-mentioned tooth portions are press-formed so as to be formed.

W1が、フランジ1aの幅W2より前記溝３の幅W3だけ小さく
なるようにして、歯部２が形成される。Next, an embodiment of the present invention will be described with reference to the drawings. In FIGS. 1 and 2, reference numeral 1 denotes a body made of sheet metal and formed in a cylindrical shape. An extension 1b is formed outward from the one end side in the circumferential direction, and a direction perpendicular to the extension 1b. The outward flange 1a is integrally formed. Denoted at 2 is a tooth portion having a trapezoidal cross section formed at a predetermined pitch on the outward flange 1a, and can be easily formed by forging the mountain portion 2a from the outer side toward the inner side (center portion of the main body 1). Can be provided. At this time, all of the tooth portions 2 (mountain portions 2a) protruding toward the inner peripheral surface of the outward flange 1a and the extending portion 1b.
The tooth portion 2 is formed by forging so that the fitting groove 3 of the wavy ring is formed between and. That is, the width of the tooth portion 2
The tooth portion 2 is formed such that W1 is smaller than the width W2 of the flange 1a by the width W3 of the groove 3.
この方法で得られるウェーブリング嵌合用溝３は必要十
分な溝深さ3Hを確保することができ、且つ上記溝底部の
板厚3tが厚く得られるので、比較的薄い鋼板を用いても
母材を破断させることなく形成（仕上げ加工）すること
ができる。The wave ring fitting groove 3 obtained by this method can secure a necessary and sufficient groove depth 3H, and since the plate thickness 3t at the groove bottom portion can be obtained thickly, even if a relatively thin steel plate is used, Can be formed (finishing) without breaking.
このようにして形成されるクラッチリテーナは、比較的
薄い鋼板を用いても、充分な強度を確保することがで

Cuts the part of the tooth that is formed,
In order to secure the predetermined groove depth 13H without breaking the base material of the bottom portion 13t of the groove, it is necessary to increase the thickness of the base material, which impedes weight reduction.

きるAs described above, according to the present invention, since the tooth portion of the flange of the clutch retainer is forged and at the same time the groove for fitting the wave ring is formed, it is possible to reduce the manufacturing process and improve the work efficiency. And the cost can be reduced. Even if a relatively thin steel plate is used as the base material of the clutch retainer, the wave ring fitting groove can be formed without breaking the base material, and acts as a rib.
It is possible to manufacture a lightweight and strong clutch retainer.
