PURPOSE:To simplify the fixture of a brush guide by forming a hole, with which a mounting leg of the guide is engaged, at a bracket, and engaging a cut and erected part with the hole of the bracket by the elastic force when passing the leg through the hole. CONSTITUTION:A cut and erected part 71 formed at the mounting leg 72 of a brush guide 45 is deflected inward against the elastic force when the leg 72 is inserted into a hole 73 of a bracket B38, and when the top of the part 71 is passed through the hole 73 of the bracket B38 out, the part 71 is returned to the original state by the elastic force to be engaged with the bottom 77 disposed near the hole 73 of the bracket B38. Thus, the guide 45 can be effectively prevented from coming off the hole 73 of the bracket B38. |
