Claims

[Claims for Utility Model Registration] (1) In a starter motor equipped with a planetary gear reduction device, the starter motor revolves around the armature rotation shaft by meshing with a sun gear formed on the outer periphery of one end of the armature rotation shaft of the DC motor. A plurality of planetary gears are rotatably supported by pins on a carrier, and the tips of the pins protrude from the planetary gears and are attached to the inner peripheral surface of an annular support projecting toward the armature rotating shaft. A starting motor with a planetary gear reduction device, characterized in that it is slidingly supported. (2) The starter motor with a planetary gear reduction device according to claim 1, wherein the annular support comprises a yoke or a front bracket. (3) The planetary planet as set forth in claim 1 of the utility model registration claim, wherein the annular support is constructed by fitting a sleeve bearing to the inner circumference of an inwardly projecting portion of a yoke or a front bracket. Starting motor with gear reduction device.
