Abstract
A carrier is supported by a case via a bearing. The bearing comprises an inner race, an outer race, rollers, and a retainer. The inner race has a tapered outer peripheral surface, and is fixed to a carrier. The outer race has a tapered inner peripheral surface facing the outer peripheral surface of the inner race, and is fixed to the case. The rollers is disposed between the inner race and the outer race. An end part of the retainer having a larger diameter makes contact with the case via a first member. The larger diameter end part of the retainer makes contact with the case via a second member. By the retainer making contact with the case and the carrier via the first member and the second member, the retainer can reduce friction compared to when making direct contact with the case and the carrier.
