Abstract: Provided is a selectable clutch with a simple structure capable of reducing friction loss, preventing noise generation, allowing size reduction, extending service life, and minimizing the load when switching modes. The selectable clutch includes a selector. One of the inner race and the outer race is formed with support grooves, and the other with pocket parts. Rollers are disposed between the inner race and the outer race, and biased into the pocket parts by a resilient member. The roller-holding surface of each support groove and the roller-holding surface of each pocket part are inclined at an angle such that, when a roller is held therebetween, a force acts on the roller in a direction to move the roller toward a corresponding pocket part. In a lock mode, the rollers are held by the support grooves, pocket parts, and selector. The roller-holding surface of the selector includes a sloped portion. [Figure 1]
