Abstract
A pulley unit made by interposing a one-way clutch in an annular space between a pulley and an axial body providing a deep groove ball bearing on a base end side of the one-way clutch, and a roller bearing on the free end side; setting an inner rolling surface of a roller of the one-way clutch to be an outer diameter surface of the axial body and an inner rolling surface of a rolling member of the roller bearing to be an outer diameter surface of the axial body. The pulley unit permits easy position setting of the pulley, so that stabilized lock and free operation can be expected and productivity can be improved.
