Abstract
A positive connection plate of a DC motor includes a fitting groove to enable assembling a specific brush holder thereto. The specific brush holder includes a convex part that fits in the fitting groove and a stepped surface having a step at a radially outer side of the convex part, and located at the opposite-core side of its armature from a core-side end surface of the convex part. A space existing in an axial stepped area which is located at the core side from the stepped surface and in which the step is formed is a stepped space. A drawing member is drawn from a position which circumferentially overlaps with the specific brush holder to the outside of a motor case, and is disposed so as to overlap with the stepped space in the axial direction.
