A plurality of rollers are disposed between an inner race and an outer race that are coaxial and relatively rotatable. The inner race and outer race are configured to engage with each other via part or all of the plurality of rollers that are held in a circumferential direction between roller support parts and pocket parts, the roller support parts being formed on one of an outer circumferential surface of the inner race and an inner circumferential surface of the outer race, and the pocket parts being formed on the other. A torque limiting member that applies a radial load on the rollers to press the rollers against the roller support parts is provided coaxially with the inner race and the outer race. The torque limiting member is flat and annular in an axial direction and resiliently deformable in a radial direction.

Positive clutch

An object of the present invention is to provide a vehicle parking lock system that realizes a parking lock with a positive user perception, and enables energy and cost reductions without complex control and with a simple configuration. The object is achieved by a selectable clutch configured to be switchable between four operating modes and provided to one of an input shaft, an output shaft, and an intermediate shaft of a transmission. The operating mode of the selectable clutch is controlled based on detection signals of a plurality of sensors to prevent an unintended movement of the vehicle when the vehicle is stationary.
