摘要

The tapered roller bearing (1) includes the tapered rollers (4) provided between an outer race (2) and an inner race (3) such that each tapered roller has a tapered surface and a large convex end surface (12) communicating with the tapered surface and corresponding to the large concave collar rib surface (15) of the inner race. An independent claim is also included for a final reduction gear.
