In a belt-driven auxiliary equipment driving apparatus for vehicle engines, a one-way clutch-integrated pulley is disposed which includes a bearing for relatively rotatably supporting inner and outer rings and a clutch mechanism for effecting or blocking torque transmission between the inner and outer rings by changing the tilting direction of sprags according to the direction of relative rotation of the inner and outer rings. In such a case, a cage of the clutch mechanism is connected to a cage of the bearing. The cage of the bearing is rotated in the same direction as that of relative rotation of the outer ring at a relative rotational speed lower than that of the outer ring, and as a result, the relative speed of bodily movement of each sprag around the inner ring is made slower than the relative rotational speed of the outer ring. During idling of the inner and outer rings, each sprag thereby slides also on the outer ring and the speed of slide of each sprag on the inner ring is lowered. This avoids abrasion from progressing only in the cam surface of each sprag in contact with the inner ring, thereby improving functional durability of the clutch.
