The pulley part has an inner portion with a frustoconical inner surface mounted on an outer cylindrical surface of the outer ring, an outer cylindrical portion having an outer cylindrical surface configured to support a belt or a chain, and an intermediate portion extending radially inward from the cylindrical outer portion to the inner portion. The pulley part is integral and has an open end on an axial side opposite the intermediate portion. The frustoconical surface extends inwardly towards the outer ring, and the inner surface is force fitted onto the outer cylindrical surface of the outer ring.
