It is possible to obtain an engine starting device in which, at the time of initial engagement of a first pinion gear and an engine starting gear, in a case where the first pinion gear collides with the engine starting gear, the first pinion gear is inclin...

The starter motor for a vehicle is capable of achieving a minimum and optimum size of a magnet switch and a starter motor in such a manner that a lever ratio R and an air gap A are improved in a range satisfying a designated moving distance P of a pinion. ...

The starter motor has a brushless variable-reluctance or squirrel cage rotor (14) with a pinion (12) mounted on its shaft (22) and able to slide axially, along grooves formed on the surface of the shaft. The rotor is axially offset so it moves axially when...

The starter has an electric motor with an axially mobile pinion (5). The coupling between the motor shaft and the pinion provides damping of mechanical shocks, using a damper disk (20) between the connection (7) to the motor shaft and the connection (8) to...
