ある。The brush base mounting device of the present invention is a brush base mounting device that assembles the brush pieces held on the brush base so that they come into sliding contact with the surface of a flat commutator. The tips of the legs protruding from the back of the outer periphery are inserted into the insertion holes on the bottom of the yoke, and the tips that protrude outward are caulked, so the brush base is not directly caulked during assembly, which prevents deformation of the brush base. Further, there is no need to form a stepped portion at the opening of the yoke, and therefore the pressure contact strength of the brush that presses against the commutator surface can be kept constant.
