A grommet (40) is coupled to one side of a brush holder stay (20). When the brush holder stay (20) is housed in an end bracket (11), a projection (42,look at Fig.4) projecting from the grommet (40) is engaged with a groove (14) which is provided in the end bracket (11). A screw insertion hole (25) opened at a position opposite to the grommet (40) of the brush holder stay (20) is adjusted with a threaded hole (16) of a boss portion formed in the end bracket (11), whereby a screw (34) is inserted therethrough and screwed in the threaded hole (16). The brush holder stay (20) is fixed to the end bracket (11) by one piece of screw (34) and the grommet (40).
