Abstract
An in-wheel motor unit comprises a housing, a motor, a speed reducer, a hub bearing comprising an inner race and an outer race, and a seal member fluid-tightly sealing a gap between the housing and the outer race. The outer race comprises a cylinder part disposed inside the housing and a flange part fixed to a housing wall surface by one or a plurality of fastening members. The housing has a projecting part with a substantially cylindrical shape extending from a housing opening in an axle inward direction. An outer peripheral surface of the cylinder part abuts against an inner peripheral surface of the projecting part. The seal member is disposed in a groove provided on the outer peripheral surface and extending over a whole periphery of the cylinder part of the outer race.
