Abstract
In order to provide a starter motor with an intermediate gear which can secure a good engaging performance for a pinion, an intermediate gear and a ring gear to thereby eliminate the strange sound of the intermediate gear and to reduce the wear of a bearing of the intermediate gear as well as the wear of the teeth of the pinion and intermediate gear, according to the invention, there is provided a starter motor with an intermediate gear in which the shift coefficient of a pinion is set smaller than the shift coefficient of the intermediate gear to thereby reduce a difference between two kinds of engagement pressure angles respectively obtained between the pinion and intermediate gear as well as between the intermediate gear and a ring gear.
