摘要： A spring type one-way clutch includes an outer ring rotatable about a rotary shaft and having an inner tubular portion, and a clutch spring mounted in the outer ring. The clutch spring includes a large-diameter coil spring portion, a transition portion connected to the winding end of the large-diameter coil spring portion, and a small-diameter coil spring portion connected to the radially inner end of the transition portion and wound in the opposite direction from the large-diameter coil spring portion. When the outer ring is rotated in the direction opposite the winding direction of the large-diameter coil spring portion, the large- and small-diameter coil spring portions are radially compressed and pressed against the inner tubular portion and the rotary shaft, allowing the rotary shaft to rotate together with the outer ring. The transition portion spirals radially inwardly in the winding direction of the large-diameter coil spring portion.

摘要： A one-way clutch is proposed which includes an outer race having a radially inner surface in which a plurality of pockets are formed. Rollers are each received in one of the pockets. Wedge-shaped spaces are defined between respective cam surfaces of the pockets and a shaft inserted through the outer race. When the shaft rotates in one direction, the rollers are wedged into the narrow ends of the respective wedge-shaped spaces, thereby locking the clutch. When the shaft rotates in the opposite direction, the rollers move toward the wide ends of the wedge-shaped spaces, thereby unlocking the clutch. The casing includes a main body and a cylindrical member fitted in the main body and made of an elastic synthetic resin. The outer race is fitted in the cylindrical member.

摘要： The object is to stably support pillars forming a retainer of the roller type one-way clutch. An outer race (11) has one end thereof closed by a flange (16) and the other end closed by a lid (22). A predetermined number of pocket bottom surfaces (17) are continuously formed on the radially inner surface of the outer race (11). A pocket (24) is defined by pillars (23) inserted on both circumferential sides of each pocket bottom surface (17). The pillars (23) have their base portions integrally joined to the lid (22), thereby forming a retainer (12). The pillars (23) have protrusions (32) at their distal ends which are fixed to holes (19) formed in the flange (16) by e.g. fusing, thereby fixing the retainer (12) to the outer race (11).
