Abstract

To provide for axial alignment of the shaft of a starter motor, the shaft is formed with a ring groove (17) and a pair of half-disks (18) positioned between a holding plate (12) of the brush holder and the end shield (6) of the starter retains the half-disks in position, the half-disks engaging in the groove to thus position the axial location of the starter shaft (3).
