ABSTRACT:
The invention relates to a brush holding device used in a motor, and a method of assembling a brush holding frame onto a base plate in the brush holding device. In the brush holding device, flanged portions are protruded from both sides of a lower portion of a brush holding frame, and a pair of fixing portions each having a recessed portion substantially identical in shape to a cross-sectional shape of a corresponding one of said flanged portions are provided. The brush holding frame is inserted between the fixing portions while being slid on and along a base plate surface until the flanged portion on both sides of the brush holding frame are respectively fitted to the recessed portions of the fixing portions. Cover portions are provided on the brush holding frame at a level lower than the guide hole so as to cover the fixing portions when the fixing portions and flanged portions are fitted together.
