To ensure durability of a one-way clutch by relieving a bearing pressure exerted on a side bearing.
The one-way clutch is provided between outer and inner races 1 and 2 with end bearings 5A and 5B to keep concentricity of two races, and either one of the two races 1 and 2 is fitted into a static member 8 and the other is fitted into a rotary member 9, the clearance of the fitting-in part between the static member 8 and the race is decreased to a value lower than that of a fitting-in part between the rotary member 9 and the race. A load applied due to whirling is released on the larger clearance. Movement in a radial direction of the race fitted in the static member side and a high load due to an own weight are supported by the static member and the applied load of the end bearing is relieved.
