Abstract
Disclosed herein is a bushing for a one-way clutch which is to be assembled in a stator of a torque converter. The bushing is useful for centering outer and inner rings of the one-way clutch and for backing up an associated thrust needle bearing. The bushing has a thrust surface to be positioned facing the thrust needle bearing and defines a center hole, an inner periphery and an outer periphery. The bushing is provided with a plurality of grooves formed in the thrust surface of the bushing and extending from the outer periphery to the inner periphery. An inward extension of a longitudinal center line of each of the grooves does not intersect a center of the bushing. The grooves may be arranged, for example, in the form of a whorl.
