歯山部2btよ内側の歯山部2aより山部断面形状が小
形でしかも狭幅に又は同等に形成されている。FIG. 1 shows a partial perspective view of a clutch retainer 1 manufactured according to the present invention, in which an outward flange 1a is formed at one end of a cylindrical drum, and teeth 2 are formed on the flange portion. The toothed portion 2 has a substantially trapezoidal cross-sectional shape, and the inward chevron portion of the flange 1a is divided into two toothed portions 2a and 2b. The cross-sectional shape of the crest is smaller and narrower than that of the tooth ridge 2a on the inner side of 2bt.
そして、二つの歯山部2a、2bに挟まれた凹部は、ス
ナップリング用溝3となっている。The recessed portion sandwiched between the two toothed portions 2a and 2b serves as a snap ring groove 3.

より剪断された剪断面として形成される。In press forming the clutch retainer 1 having such a structure, the present invention provides an upper die 4 for forming the toothed portion 2a inside the clutch retainer 1, and a toothed portion 2b as shown in FIG. It has a lower die 5 for forming the snap ring groove 3 and a middle die 6 for forming the snap ring groove 3 between the upper die 4 and the lower die 5. A forging device equipped with a pan differential is used 1. This forging device simultaneously forms the teeth 2 and the snap ring groove 3, and as shown in Fig. 3, both sides of the snap ring groove 3 are formed. wall 3
a and 3b are formed as sheared surfaces that are sheared by the inward bulge of the gear tooth portions 2a and 2b.

ておく。When the tooth portion 2 and the snap ring groove 3 are molded simultaneously in this way, the outer tooth ridge portion 6a of the middle die 6 is fitted into the snap ring groove 3, so the clutch retainer 1 is removed after molding. However, in the case of the present invention, the payout can be made easily. That is, as shown in FIG.
The tooth thickness '6a of a is set to be larger than the tooth thickness 128 of the tooth ridge portion 2a in order to form the predetermined snap ring groove 3, but the trough portion sandwiched between the tooth ridge portions 2b is Since the tooth thickness is set to be smaller than the tooth thickness 15a of the outer tooth ridge portion 5a of the lower die 5 to be formed, when the middle die 6 is rotated by a half pitch after forming, the outer tooth of the middle die 6 as shown in FIG. The crest 6a is removed from the snap ring groove 3 and moved to a position where it overlaps the outer peripheral gear 5a of the lower die 5. Therefore, if the knock ring 1-0 is raised in this state, the clutch retainer 1 can be removed from the upper die 4, the middle die 6, and the lower die 5, and the clutch retainer 1 can be taken out. Note that the punch 7 is moved outward in advance.

Driver pin 8 with the tip bent as shown in the figure
The driver pin 8 is raised and the tip 8a is inserted into the hole 6b formed in the middle die 6.
By pushing the inclined wall 6C, the middle die 6 is moved to the arrow A
can be moved in the direction. By appropriately setting this movement stage, the middle die 6 can be rotated by exactly half a pitch. Conversely, when the driver pin 8 is lowered, the middle die 6 can be returned to its original position by moving laterally.

である。Furthermore, in the above embodiment, an example was shown in which a snap ring groove was formed on the inner surface of the flange, but in contrast to this, a punch was placed on the inner surface and a die was placed on the outer surface to form the predetermined teeth and grooves. It can also be applied when forming a snap ring groove on the outer surface. The present invention can be widely applied not only to clutch retainers but also to members having teeth and snap ring grooves.
