ABSTRACT:
An inertia drive engine starter comprising an electric motor having an armature shaft provided with an axial, bottomed central bore in the front end, a slide output shaft provided with a pinion at the front end thereof and a stopper at the rear end thereof received in the bottomed central bore of the armature shaft, and an overrunning clutch for transmitting the torque of the armature shaft to the slide output shaft. Internal helical splines formed in the inner surface of the inner race of the overrunning clutch and external helical splines formed in the outer surface of the slide output shaft are engaged to transmit the torque of the armature shaft to the slide output shaft and to thrust the slide output shaft to the front when the electric motor is actuated. The axial movement of the slide output shaft is limited to a predetermined fully advanced position by the engagement of the stopper provided at the rear end of the slide output shaft with the inner race of the overrunning clutch, which is restrained from axial movement.
