Abstract
A starter for automotive engines is provided which is equipped with a planetary gear train working as a speed reducer. The starter also includes a partition plate and a thrust washer. The partition plate extends radially of the starter between an electric motor and a planetary gear train to isolate the planetary gear train from a motor chamber. The thrust washer extends radially of the starter in abutment with the partition plate so as to bear a thrust load, as transmitted from the planetary gear train. The thrust washer also includes an outer peripheral portion which is placed between a rear end surface of an internal gear of the planetary gear train and the front end surface of the partition plate and has an elastic mechanism working to elastically urge the internal gear of the planetary gear train frontward in the axial direction of the starter.
