Abstract
In a starter system for an internal combustion engine using a planetary reduction gear unit, the internal gear of the planetary reduction gear unit, the center bracket accommodating the internal gear and the pinion cover are joined together so as not to rotate relative to one another by using radial projections provided in the outer circumferential surface of the internal gear which are passed through openings provided in the center bracket and received by associated recesses provided in the pinion cover. The three members are thus prevented from rotating relative to one another with a simple structure which is also easy to assemble. The projection of the internal gear may also be used for securing an annular seal member interposed between an axial end surface of the internal gear and the corresponding shoulder surface of the center bracket.
