ABSTRACT:
A ratchet type one-way clutch in which an outer ring is made of aluminum is improved in durability. In order to solve such problems as an increase in the number of parts, complication, bulkiness, an increase in weight and an increase in cost, there is provided a one-way clutch with the lock-up function also having the function of idly rotating only in one direction and the function of blocking the rotation in both directions. In a ratchet type one-way clutch having an outer ring having a pocket in the inner periphery thereof, an inner ring disposed coaxially with the outer ring and having a notch in the outer periphery thereof, a pawl contained in the pocket and fitted in the notch of the inner ring for transmitting torque between the inner ring and the outer ring, and a resilient member for biasing the pawl toward the inner ring, the outer ring is made of aluminum, and the inner peripheral side surface of the outer ring is subjected to a hardening process.
