Abstract

An inertia-drive starter is proposed, in the case of which a relay is not required to engage the pinion in the flywheel ring gear (47) of an internal combustion engine. With this starter, a pushing-forward of the driven shaft (33) to engage a pinion (45) in the flywheel ring gear (47) is brought about by means of a pole tube (9) located on the stator (5) of the starter motor (5, 7), which said pole tube executes a turning motion around the motor axis when the starter motor (5, 7) is energized. Means (55, 63, 77, 79) are provided that convert the turning motion of the pole tube (9) directly into an axial motion acting on the driven shaft (33).
