Abstract

　A carrier is supported on a casing via a tapered roller bearing. The tapered roller bearing comprises an inner race, an outer race, tapered rollers and a retainer. The inner race is mounted to a carrier. The outer race is mounted to a casing. The tapered rollers are positioned between the inner race and the outer race. The outer peripheral surface of the inner race and the inner peripheral surface of the outer race are not provided with ribs that restrict the tapered rollers from moving in a direction away from the central axis of the bearings. The end where the diameter of the retainer is the greatest comes into contact with the carrier in the central axis direction of the bearing, and comes into contact with the casing in a direction perpendicular to the central axis of the bearing.
