Patent ID: 10177623

Abstract:
A first brush holder is assembled to a core-side connection plate by inserting a slit insertion portion into a slit from an outer circumferential side of the core-side connection plate, and a radial outside position of the first brush holder to the core-side connection plate is regulated by both sides in a circumferential direction of a first slit being inserted into a pair of guiding grooves. A radial outside position of the brush holder is regulated by being fixed to a counter-core-side connection plate by press-fitting a convex portion provided on a counter-core-side of the first brush holder into a second slit of a counter-core-side connection plate. A second brush holder is assembled to the counter-core-side connection plate from an outer circumferential side of the counter-core-side connection plate, and a radial outside position is regulated by the core-side connection plate.
