は非常に重要であつた。 In such a structure, the one-way clutch 20 is attached by a snap spring 24, but conventionally this snap ring 24 is attached to a second
It was shaped as shown in the figure. That is, a small notch 24a is provided at one location on the circumference so that the diameter can be elastically reduced, thereby allowing for attachment and detachment. FIG. 3 shows a state in which this snap ring 24 is assembled into the transmission case 12. By the way, as shown in FIG. 1, a park gear 25 for fixing the output shaft 23 is arranged adjacent to the snap ring 24, and this park gear 25 is connected to a parking pole 27 operated by a park rod 26 (FIG. 3). It is then fixed as necessary. The parking pole 27, which can swing around the pin 28, usually has a return spring 29.
is placed in a non-meshing position by the Conventionally, it has been necessary to arrange the one-way clutch 20 and the park gear 25 with a sufficient distance in the axial direction so that the parking pole 27 and its return spring 29 do not interfere with the snap spring 24. That is, it was necessary to make dimension A in FIG. 1 a certain value or more. Therefore, there was a problem in that the axial dimension of the automatic transmission became large. Particularly in front-wheel drive automatic transmissions, how to reduce the axial dimension is an important issue, and the above-mentioned problem has been very important.

１図におけるＡ寸法を小さくすることができる。 FIG. 4 shows a snap spring 30 according to the present invention. The nearly circular snap spring 30 has a cutout portion 30 having a predetermined arc length (a length slightly longer than the length of the parking pole 27) that is larger than the normal case.
a, and one cutout end is provided with a positioning pawl 30b extending outward. FIG. 5 shows a state in which this snap spring 30 is assembled into an automatic transmission. Transmission case 1
A parking pole 27 that is swingable about a pin 28 fixed to the output shaft 23 is arranged so as to be able to mesh with a park gear 25 that is integrated with the output shaft 23. Parking pole 27 is usually return spring 2
When the parking rod 26 is actuated, it rotates counterclockwise and engages with the parking gear 25. The snap spring 30 has a notch 30
A is mounted so as to face the location where the parking mechanism consisting of the parking pole 27, return spring 29, parking rod 26, etc. is arranged. Further, the positioning pawl 30b of the snap ring 30 is located within the spline groove 12a for fixing the clutch plate of the transmission case 12.
Rotation is prevented so that the circumferential position of 0 does not change. It is clear that the one-way clutch 20 can be secured in a conventional manner by means of this snap ring 30. Further, since the snap spring 30 does not exist near the parking pole 27 (that is, it is a notch 30a), the parking pole 27 and the return spring 19
There is no risk of interference with the snap spring 30,
One-way clutch 20 and parking pole 25
can be arranged as close as possible, and dimension A in FIG. 1 can be made small.
