Provided is a low-cost roller clutch equipped with support bearings having excellent transmission performance and durability and for which it is possible to surely prevent interference between component members. Of the component members of a roller clutch 10b, a first support bearing 29 and second support bearing 30, an outer-ring member 27 is common. A first race member 33, which functions as the inner ring of the first support bearing 29, and a clutch inner-ring member 28 are a single body. The clutch inner-ring member 28 and a second race member 34 of the second support bearing 30 are separate bodies. A clutch retainer 15b is held between the back-end sections of concave sections 19 of a cam surface 18 and the end edge of the second race member 34, and displacement in the axial direction of the clutch retainer 15b is suppressed. As a result, the clutch retainer 15b is prevented from hindering the rotation of the first support bearing 29 and second support bearing 30. |
