DC commutator motor that prevents variation in characteristics of the motor and suppressing deterioration of performance, and reduces the number of assembly steps. A magnet is attached to an inner circumferential surface of a bottomed cylindrical bracket to form a field pole. In an armature, a commutator is fastened to an armature core which is formed by laminating a plurality of thin core sheets. Shaft is inserted into the integrated body of the armature core with the commutator. Armature coil is wound within slots provided in the armature core, and bearings are attached. The armature is assembled with the field pole. Polygonal protruding portion which is made of resin is provided in the commutator, the protruding portion fastened to inner circumferential surfaces of the slots of the armature core, and the shaft is then inserted. |
