Due to this contact, the rattling suppressing member 52 comes into close contact with the rotating member 30 and the cover member 31, thereby preventing rattling of the rotating member 30.

また前記ロック部材52が前記ロック解除位置となったときには、図7(b)で示すように、前記収容孔55の長手方向両端部のうち前記移動方向62に沿う後端部が前記がたつき抑制部材53に当接し、前記コイルばね63の勢力に抗して前記がたつき抑制部材53は前記移動方向62に押されることになり、前記がたつき抑制部材53の前記斜面53aが前記凹部側斜面61aから離反する側に前記がたつき抑制部材53が移動し、がたつき防止状態が解除されることになる。 Further, when the locking member 52 is in the unlocked position, as shown in FIG. The rattling suppressing member 53 comes into contact with the suppressing member 53 and is pushed in the moving direction 62 against the force of the coil spring 63, so that the slope 53a of the rattling suppressing member 53 moves into the recessed part. The rattling suppressing member 53 moves to the side away from the side slope 61a, and the rattling preventing state is released.
