PURPOSE: To enable use of a long brush and to provide a lengthened service life by integrally molding the outer frame, the brush holder, the support for the pigtail connecting board of one polarity, and the support for a grommet which holds the pigtail of the other polarity, of a rotating electric machine.

CONSTITUTION: Outer frame 12a and a plurality (four, in the drawing) of brush 13a, 13b holders 12b, 12c of a rotating-electric machine are molded integrally. A supporting part 16 for a connecting board 15 of pigtails 14a, 14b from negative side brushes 13a, 13b and a notch 18 to be inserted with a grommet 17 for holding the positive side pigtails 14b, 14b and arranged at the opposite side to the supporting part 16 are also molded integrally with the outer frame 12a and the brush holders 12b, 12c. Coil springs 19 are inserted into the brush holders 12b, 12c in order to urge the brushes 13a, 13b toward the center. By such arrangement, a long brush can be employed and the assembling work is carried out efficiently.
