ラシ交換の際ブラシのみの交換ですみ、ブラシに必要と
されていた異形管、保持器が不必要となりブラシを安価
にすることができる。Function The present invention has the structure described above, and since the brush can be prevented from being removed and held and fixed by bending the tab of the irregularly shaped tube, when replacing the brush, only the brush needs to be replaced. A container is not required and the cost of the brush can be reduced.
さらにブラシ保持器をモータフレームから取りはずす必
要がない為、ブラシの交換も容易にすることができる。Furthermore, since there is no need to remove the brush holder from the motor frame, the brushes can be easily replaced.
実施例
以下、本発明の実施例について図面を参照しながら説明
する。EXAMPLES Hereinafter, examples of the present invention will be described with reference to the drawings.
第１図は、本発明のブラシ組立の斜視図であり、第２図
