弾性片１５は第１０図に示すようにウエブ７の面
に沿う程度に大きく変形する。 This spring member 10 is fitted on the outside of the web 7, and the outer diameter of the spring member 10 is adjusted by the engagement between the bent piece 16 formed at the end of the other spring plate portion 14' and the inner diameter edge of the web 7. The roller 9 is pressed by a pair of elastic pieces 15 facing the roller pocket 8 in order to prevent it from coming off in the direction, but when the transmission of rotational torque is cut off, the roller 9 moves into the wedge-shaped space due to inertia etc. In many cases, the elastic pieces 15 move more than necessary toward the outer part of the web 7, and due to the movement of the roller 9, the pair of elastic pieces 15 are greatly deformed to the extent that they follow the surface of the web 7, as shown in FIG. .
弾性片１５の上記のような変形は、回転トルク

以上に変形するのが防止される。(5) Effect The roller retainer according to this invention has the above-mentioned configuration, and when the roller one-way clutch is switched from a state in which rotational torque is transmitted to a state in which transmission is interrupted, the roller moves toward the wide part of the wedge-shaped space. However, the elastic piece of the spring member is pushed by the roller and deforms. When the amount of deformation of the elastic piece increases, the elastic piece comes into contact with the protrusion, and the protrusion prevents the elastic piece from deforming more than necessary.

に向けて傾斜している。 Furthermore, a pair of protrusions 28, 28 for regulating the amount of deformation of the elastic piece 15 are provided on both sides of the surface of the web 23 facing the elastic piece 15. Each of the protrusions 28, 28 extends from the inner surface of each side ring 21, 22 toward the center of the web 23, and its front surface in the circumferential direction is inclined toward the bending line of the elastic piece 15 facing thereto.
上記の構成から成るローラ保持器２０は、第２

広間〓部に臨むことによつて、外輪１に対する回
転伝達が遮断される。 Now, in the state shown in FIG. 6, when the inner ring 2 is rotated in the direction of the arrow, the roller 9 bites into the narrow part of the wedge-shaped space 4, so that the rotation of the inner ring 2 is transmitted to the outer ring 1. Therefore, when the inner ring 2 is stopped or moved in the opposite direction, the roller 9 moves to the right in FIG. 6 and deforms the elastic piece 15 of the spring member 10, causing the roller 9 to By facing the outer ring 4, rotation transmission to the outer ring 1 is blocked.
上記のように、回転トルクの伝達状態から伝達
を遮断する状態に切り控えたとき、ローラ９には
慣性力が作用して弾性片１５を必要以上に変形さ

ことになり（第１２図参照）、弾性片１５は所定
量変形すると、それ以上変形するのが防止され
る。 As described above, when the rotational torque is cut from the transmitting state to the transmitting state, the inertial force acts on the roller 9 and tries to deform the elastic piece 15 more than necessary. When the elastic piece 15 deforms to a predetermined position, its back surface comes into contact with the protrusion 28 (see FIG. 12), and when the elastic piece 15 deforms by a predetermined amount, it is prevented from deforming further.
なお、第６図に示すように、弾性片１５がロー
ラ９で押されてウエブ２３の方向に所定量変形す

ようその突出縁２５の突出量を規制しておくこと
により、上記と同様に弾性片１５が必要以上に変
形するのを防止することができる。 As shown in FIG. 6, when the elastic piece 15 is pushed by the roller 9 and deforms by a predetermined amount in the direction of the web 23, the protruding edge 25 is bent so that a part of the roller 9 comes into contact with the tip of the protruding edge 25. By regulating the amount, it is possible to prevent the elastic piece 15 from deforming more than necessary, similarly to the above.
また、ローラ保持器２０を構成する一方の側面
