スラスト力を受け、それらのスキューを防止している。In FIG. 4, A is a pinion gear, B is a carrier plate, and C is a pinion shaft. The pinion gear A is rotatably supported on a pinion shaft C via a number of needles D. Two flat washers E are arranged on both sides of the pinion gear A between the pinion gear A and the carrier plate B so as to receive the thrust force of the pinion gear A. Further, the flat washer E comes into contact with the end of the needle D, receives a thrust force by the needle D, and prevents skew thereof.

しやすく耐久性上の問題があった。However, in such a conventional carrier device, since the thrust force of the needle D is received by the two flat washers E, it is necessary to sufficiently secure the rigidity thereof. In this case, the plate thickness of the washer E must be increased, and the axial length of the entire carrier device becomes large, which is an obstacle to shortening the overall length of the automatic transmission. Further, since the end of the needle D is in sliding contact with the flat washer E while rotating and revolving, the end of the needle D tends to generate heat and has a problem in durability.

The length of the automatic transmission and thus the overall length of the automatic transmission can be reduced. Further, since the contact area between the outer curved surface and the end surface of the needle 6 is relatively large, the surface pressure is reduced and wear is reduced.

Although the example using the pinion washers 7 and 8 was shown,
The reason why a plurality of washers are provided is to sequentially decrease the relative sliding speed between the pinion gear 1 and the carrier plates 2 and 3. In the case of a model having a relatively low relative sliding speed, the washer is provided with the first pinion. Only one washer 7 may be used.

歯車のキャリア装置を得ることができる。As is apparent from the above description, according to the present invention, a folded portion holding a ring member is formed on the inner diameter side of the pinion washer, and the outer curved surface of the folded portion and the end of the needle bearing are formed. Since the portions are brought into contact with each other, sufficient rigidity can be obtained without increasing the thickness of the pinion washer, and the axial length can be reduced. In addition, since the shape of the outer curved surface of the folded portion can be determined depending on the shape of the ring member, the degree of freedom of the shape is increased, and at the same time, stability of an important dimension when receiving thrust of the needle is obtained, It is possible to obtain a carrier device of a planetary gear having excellent durability with reduced contact pressure with the needle.
