The endframe is provided with a journal in which is mounted a bearing supporting the drive shaft. Further disposed in the endframe are brushes in contact with a commutator portion of the assembly, and brush tubes for supporting the brushes. A brush retainer is mounted on the journal and has a face portion overlying a face portion of the bearing. The journal is provided with ribs which extend axially of the retainer. The ribs are engaged with the retainer, which is plastic, and hold the retainer in non-rotative fashion with the retainer face portion abutting an end of the commutator portion.
