Claims

[Scope of utility model registration request]

A DC motor, a planetary reduction mechanism mounted on the armature shaft of the DC motor, and an overrunning clutch provided on the output shaft of the planetary reduction mechanism, which is gear-engaged with the engine flywheel gear. The starter motor has a configuration in which the output shaft is supported by a front machine frame, and the planetary motion body of the planetary reduction mechanism is brought into contact with the inner peripheral surface to absorb rotational reaction force of the planetary motion body. It has an intermediate bracket having an annular surface for receiving pressure formed on its inner circumferential surface, the open end of this intermediate bracket is closed with a flange portion formed by an extension of the yoke of the motor, and the other end of the intermediate bracket supports the output shaft. A starter motor characterized in that the space is closed by a flange of an intermediate bracket, and the planetary speed reduction mechanism is housed in the closed section.
