Abstract

PURPOSE:To reduce the thickness of a motor by mounting a brush holding member onto the internal surface of the bottom of a case in the periphery of a bearing and forming structure in which an end cover is not set up. CONSTITUTION:A bearing metal 22 for pivotally supporting a motor shaft 25 is fixed at the center of the bottom of an external cylinder case 21, and a field magnet 23 is fastened onto the inner circumferential surface of the external cylinder case 21. A revolving armature is composed of a cuplike yoke 24, a grooved core 28 and a winding 29, and the revolving armature is supported rotatably by the motor shaft 25. A brush holding member 31 is set up around the bearing metal 22 on the internal surface of the bottom of the case 21, and a brush 32 slid onto the conductor circumferential surface of a commutator 26 is held by the brush holding member 31.
