The plain bearing is arranged adjacent to and on an axially outer side of a side portion of the one-way clutch and between an inner ring and an outer ring of the one-way clutch, and on its inner and outer peripheries, has flanges with bearing tracks formed thereon. The side plate is arranged on an axially outer side of the plain bearing and at a position adjacent to the plain bearing such that the side plate serves not only as a stopper for the plain bearing but also as a bearing track for a needle bearing. The plain bearing and side plate are provided with engageable portions, respectively, and are maintained in engagement with each other via the engageable portions.
