Abstract
In a roller type one-way clutch before an inner race contacts with rollers, the inner race is centered by a pad bearing, whereby it becomes unnecessary to use a special assembling jig and also the working property of assembly can be improved without increasing the number of steps of assembling the one-way clutch. The roller type one-way clutch comprises an outer race having an axially extending annular inner peripheral cam surface, an inner race disposed inside the outer race and having an annular outer peripheral raceway surface, the outer race and the inner race being space apart from each other and disposed concentrically with each other for rotation relative to each other, a roller member disposed between the outer race and the inner race for transmitting a torque between the outer peripheral raceway surface and the inner peripheral cam surface, and a pad bearing for centering the inner race relative to the outer race, the roller member having on at least one of the axial opposite end portions thereof a chamfered portion chamfered over the entire periphery thereof.
