Abstract
In an annular space between a pulley and a shaft body disposed coaxially with each other, a one-way clutch is interposed in an intermediate range in an axial direction and rolling bearings are disposed on both sides in the axial direction of the one-way clutch. A tightening distance for fitting between the one-way clutch and pulley is set to be smaller than that between the rolling bearing and pulley. Due to this structure, in a condition in which an excessive radial load acts upon the pulley, that radial load acts on not the one-way clutch but the rolling bearings on both sides thereof, so that a clutch operation of the one-way clutch can be carried out stably.
