Abstract

A starter for starting an internal combustion engine has an electric starter motor, which has a drive shaft provided with an external toothing, a pinion shaft bearing a pinion, and a clutch element of a roller-type overrunning clutch situated between the drive shaft and the pinion shaft. The clutch element has an internal toothing mating with the external toothing of the drive shaft and is shiftable together with the pinion shaft away from the starter motor in the axial direction of the drive shaft into a meshing position in which the pinion mates with a gear wheel or ring gear of the internal combustion engine. The starter also has a device provided for directly supporting the pinion shaft on a section of the external toothing of the drive shaft facing away from the starter motor.
