Further, a spring portion 78 protruding in the axial direction is formed on the outer peripheral edge portion of the retainer washer 77, and the spring force of the spring portion 78 presses the outer ring 71 against the snap ring 79, whereby the outer ring 71 moves about the axis. Is restrained to prevent the outer ring 71 from swinging around when the inner ring 72 changes its rotation direction, thereby preventing the rattling noise generated when the convex portion of the housing 70 hits the convex portion (teeth) of the outer ring 71. I try to prevent it.

されている場合に特に問題となりやすい。By the way, in such a one-way clutch, a friction torque Tm is generated in accordance with the axial load force of the spring portion 78, and the friction torque Tm, the lock torque Tr, and the idling torque Tf are generated. Since Tm <Tr and Tm> Tf, respectively, the outer ring 71 of the outer ring 71 in the operating state of the one-way clutch is, as shown in FIG. The position of the outer ring 71 is kept in contact with the inner ring 72 and the rotation of the outer ring 71 when the inner ring 72 changes its rotation direction to the idling side F is suppressed. However, when the lock torque is applied, the contact surfaces of the housing 70 and the outer ring 71 are slightly elastically deformed in reality, and therefore, the outer ring is slightly circled due to repeated locking and idling of the inner ring. Is swinging in the direction. At this time, since the outer wheel moving speed to the lock side R is faster than the outer wheel moving speed to the idling side F, the retainer washer 77 moves integrally with the outer wheel when the outer ring 71 moves to the idling side F. Although the position does not shift, it cannot follow the movement of the outer ring 71 to the lock side R, and the outer ring 71
Relative to the inner ring idling side F, the mounting portion 77a of the retainer washer 77 comes into contact with the circumferential side surface 70c of the housing recess 70a on the inner ring idling side as shown in FIG. It turns out that it may hurt. As described above, when the housing recess 70a is scratched, abrasion powder is generated, and this abrasion powder may hinder the automatic shifting operation of the automatic transmission, for example. This is especially likely to be a problem when the housing 70 is made of a light alloy such as an aluminum alloy.

来より周知である。On the other hand, the retainer washer 6 is integrally formed at its outer peripheral edge with a mounting portion 6a which engages with the mounting groove 1c and is mounted on the outer ring 1. Similarly, the retainer washer 7 is also integrally formed at its outer peripheral edge with a mounting portion 7a that engages with the mounting groove 1b and is mounted on the outer race 1. As a result, the retainer washers 6 and 7 are attached to the side surfaces of the outer ring to suppress the axial movement of the engaging member 3. A spring portion 7b is provided on the outer peripheral edge of the retainer washer 7 to exert a frictional force between the housing 9 and the outer ring 1. The action of the spring portion 7b will be described later, but is well known in the art.

れる。The housing 9 is formed with a concave portion 9a into which the convex portion 1a of the outer ring 1 is spline fitted. The housing 9 is formed with a step portion 21 facing the one retainer washer 7 and a snap ring 10 facing the other retainer washer 6 is attached. A snap ring may be attached instead of the step 21,
In this case, the snap ring is considered part of the housing.

The outer ring 1 is brought into contact with the snap ring 10 by its spring force.
Can be pressed against. Therefore, due to the spring force, the outer ring 1
Since a frictional force acts between the outer ring 1 and the housing 9 to restrain the movement of the outer ring 1 around its axis, the outer ring 1 is prevented from swinging around when the inner ring 2 changes its rotation direction to the idling direction.
It is possible to prevent the rattling noise generated by the concave portion 9a of the outer ring 1 hitting the convex portion 1a of the outer ring 1.

Although not located in a, the stepped portion 20 of the outer ring 1 may be omitted if necessary, and the structure may be the same as the mounting portion structure on the retainer washer 6 side. In this case, the mounting portion is located inside the recess 9a.

位置決めが容易となる。Further, in the vicinity of the mounting portion 6a of the retainer washer 6 and on the idling direction side of the inner ring 2, a projection 11 protruding radially outward is formed on the outer peripheral surface 1b of the end portion of the mounting groove 1a of the outer ring 1. Thus, the mounting portion 6a serves as a stopper portion S so as not to move in the inner ring idling direction F. As can be understood from FIGS. 4A and 4B for details of the protrusion 11, the side face 1b of the outer ring 1 is appropriately pressed with a tool, for example, a spherical tool to form the recess 12 by plastic deformation, and the amount of plastic deformation is Is bulged outward in the radial direction to form a protrusion 11.
This prevents movement of the mounting portion 6a of the retainer washer 6 in the idling direction F of the inner ring, so that the housing 9
Since the recess 9a is not in contact with the circumferential wall surface 9b on the inner ring idling direction side, the problem of scratching the recess 9a of the housing 9 does not occur. If necessary, this protrusion 11 may also be formed on the locking direction side R of the inner ring 2 in the same manner. By forming the protrusions 11 on both sides of the mounting portion 6a in this way, the positioning of the mounting portion 6a becomes easy.
