The starter includes a planetary type reduction gear device for reducing rotational speed of a motor, the planetary type reduction gear including a sun gear coupled to a shaft of the motor, planetary gears engaging with the sun gear and a planetary carrier outputting a revolutional motion around the sun gear of the planetary gears as a drive torque of the motor. The starter further includes a one-way clutch transmitting the drive torque from a side of a clutch outer thereof to a side of a clutch inner thereof through rollers disposed in cam chambers formed between the clutch outer and the clutch inner. The clutch outer is integral with the planetary carrier. The planetary carrier is integrally formed with planetary shafts rotatably supporting the planetary gears, and projecting pins projecting in the same direction as the planetary shafts. The planetary shafts are located inwardly of the cam chambers.
