Abstract
A starter is comprised of a starter motor, a planetary gear speed reduction mechanism including a sun gear, a plurality of planetary gears and an internal gear, a casing rotatably supporting the output shaft via a bearing and an outer cylindrical member coupled with the casing. The planetary gear speed reduction mechanism has an internal gear block having the internal gear, and the internal gear block is disposed in the cylindrical member and spline-fitted to the casing. Thus, a labyrinth is formed between the internal gear block and the casing.
