Kind Code:
A1
Abstract:
In this vehicle brake, for example, a one-way clutch includes: a coil spring that is interposed between a first rotation transmitting part and a second rotation transmitting part and is configured so that at least one among an increase and decrease in winding diameter occurs when a force is received from the first rotation transmitting part and so that the other among the increase and decrease in winding diameter occurs when a force is received from the second rotation transmitting part; and a frictional engagement member having a circumferential surface including a textured surface that locks the rotation of the coil spring by interfacial friction with the outer circumferential surface or the inner circumferential surface of the coil spring, and that permits the rotation of the coil spring by coming into a sliding contact with the coil spring only when the one among the increase and decrease in winding diameter occurs due to the first rotation transmitting part.
