Abstract
A rear-end bearing accommodating portion that has a floored cylindrical shape is formed integrally on a rear bracket. A brush apparatus is mounted to the rear bracket by mounting a slinger portion onto an end portion of a shaft so as to cover slip rings. A rectifier is mounted to the rear bracket in close proximity to the rear-end bearing accommodating portion and the slinger portion. A rolling bearing is configured into a creep preventing bearing in which a resin band is mounted into a ring-shaped recessed groove that is recessed into an outer circumferential surface of an outer ring. A first slit is disposed through the slinger portion so as to be positioned so as to face downward when mounted to a vehicle and so as to communicate between an internal portion and an external portion of the slinger portion.
