PROBLEM TO BE SOLVED: To reduce the cost.SOLUTION: A plurality of teeth T formed in an armature core 56 includes an axial part Tc and a first branch part Ta and a second branch part Tb each of which is branched from a tip of the axial part Tc. Coil parts C1 to C12 in an inner side are concentratedly wound to the axial part Tc. Coil parts C13 to C24 of an outer side are separately wound to the first branch part Ta of one teeth T of the adjacent teeth T and the second branch part Tb of the other teeth T. The coil parts C1 to C12 in an inner side are formed by a plurality of inner side windings, and in the inner side winding, the plurality of coil parts in the inner side is formed between one end side wire connection part connected to a segment S of a commutator 54 and the other end side wire connection part. Similarly, the coil parts C13 to C24 are formed by the plurality of outer side windings, and, in each of the outer side windings, the plurality of coil parts in the outer side is formed between one end side wire connection part connected to the segment S of the commutator 54 and the other end side wire connection part.SELECTED DRAWING: Figure 1 |
