Filed: 1992-07-09
Abstract: PURPOSE:To relieve the extent of force being added to a retainer due to interference with an engager at the time of high torque load, in an outer ring type two-way clutch. CONSTITUTION:A large diametral side retainer 12 is made to contact with the inner circumferential surface of an outer 1 in a slidingly rotatable manner, and this retainer 12 is expanded in its diameter by an elastic snap-ring 15, attaching it to the outer ring 1 under pressure. In succession, a stopper pin 22 pressed in the retainer 12 is fitted in a square hole of a small diametral side retain 13 with some play. When large force is added to the retainer 12 from a sprag 19 by torque load, the retainer 12 slidingly rotates, thereby relieving this force. In addition, with the stopper pin 22, the small diametral side retainer 13 is rotated together with the counterpart, thus a positional relationship between both these retainers 12, 13 is maintained in this way.
