A starter motor has a rotating armature with a rotating shaft on which a groove is formed, a rear bracket, and a cylindrical-shape yoke connected to a front bracket which supports a pinion shaft. A holder washer member is inserted rotatively in the groove and limits movement in the axial direction of the rotating armature. A holder plate member is provided with a brush holder member. The holder washer member is sandwiched in an axial direction between a step portion of the rear bracket and an inner peripheral portion of the holder plate member. An outer peripheral edge portion of the holder plate member is sandwiched between an outer peripheral edge portion of the rear bracket and a step portion of the yoke. As a result, the rear bracket is fixed by a through-bolt to the front bracket. In the starter motor structure the holder plate member can be fixed to the rear bracket without using a fixing component such as a screw. |
