Abstract

PURPOSE:To make a device thinner, by arranging retaining sections having a slot for penetrating a shaft through a bracket, and by retaining ball bearings between the retaining sections and end rings. CONSTITUTION:On the inner peripheral surfaces 10a on the shaft 2 sides of aluminum-die-cast end rings 10 arranged on the axis-directional end surfaces of a rotor 1, the outer rings of ball bearings 6 are butted. On a bracket 11 fixed on a stator 3 with screws 4, retaining sections 11a having a slot 12 for penetrating the shaft 2 through are arranged, and the retaining sections 11a are butted to the inner rings 6a, and the retaining sections 11a, the inner peripheral surfaces 10a of the end rings 10, and the ball bearings 6 are retained. The ball bearings 6 can be positioned at the inner peripheral sections of the end bracket 11, and so a motor can be made thinner.
