ABSTRACT:
A pulley unit improved in axial positioning of a cage of a one-way clutch is provided. An outer radius of an orbital portion of inner rings of two rolling bearings disposed at both axial sides of the cage are designed to be larger than an inner radius of the cage, so that axial movement of the cage is constrained. Due to this structure, projecting and recessing portions disposed on the cage of the one-way clutch and on an inner ring become unnecessary and can be eliminated.
