Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a brush holder capable of determining whether the length of a brush in a pressing direction is equal to or less than a predetermined length.SOLUTION: A holder 52 that surrounds a brush 51 in such manner that the brush is pressed against a slip ring 151 is provided with an exposure hole 521 (check hole) and a second reference line 522 (second mark) as means to determine whether the length of the brush in the pressing direction is equal to or less than a predetermined length as the brush wears. The brush 51 is provided with a first reference line 513 (first mark) for indicating a guide for the length of the brush 51 to be replaced. 【課題】ブラシの圧接方向における長さが一定長さ以下となったことを判別することが可能なブラシホルダーを提供する。【解決手段】ブラシ５１がスリップリング１５１に圧接するようにブラシを取り囲むホルダー５２において、ブラシの圧接方向における長さがブラシの磨耗に伴って一定長さ以下となったことを判別するための手段として露出孔５２１（確認孔）、第２目安ライン５２２（第２目印）が設けられている。ブラシ５１には、ブラシ５１を交換するべきブラシ５１の長さの目安を示す第１目安ライン５１３（第１目印）が設けられる。【選択図】図２
