Parking lock clutch

A parking lock clutch comprising:

• an outer race;
• an inner race that is provided coaxially with the outer race and so as to be capable of rotating relative to the outer race;
• a plurality of rollers disposed between the outer race and the inner race;
• a biasing member that biases the rollers in a radial direction toward roller accommodating portions provided in one of the outer race and the inner race;
• a selector configured to be capable of switching an operating mode between a lock mode in which relative rotation of the inner race relative to the outer race is prohibited and a free mode in which relative rotation of the inner race relative to the outer race is permitted;
• and a selector drive mechanism that drives the selector to rotate, wherein
• in the lock mode, the rollers are sandwiched in a circumferential direction between the roller accommodating portions and roller support grooves provided in the other of the outer race and the inner race, and the selector presses the rollers against the roller support grooves, and
• roller contact surfaces of the selector that come into contact with the rollers are configured as inclined surfaces that are inclined with respect to the circumferential direction.
