Abstract

See full text

A motor pump includes a base body, a pump, and a motor. The motor includes a tubular yoke having a bottom and an opening on a base body side, a bearing, a rotation shaft, a rotor, a commutator, a brush and a brush shaft. The bearing is fitted to an inside of a bearing hole of the base body. The brush holder is fitted to an inside of the yoke and engages with an outer peripheral surface of the bearing. The brush holder and the bearing are disposed so as to be spaced from the base body in an axial direction of the rotation shaft. The motor-side seal member is provided between the yoke and the base body. The base body constitutes a stopper that prevents the brush holder from being extracted from the yoke.
