Abstract
A starting device has a pinion for a drive of a toothed rim of an internal combustion engine, an engaging relay having an armature which axially displaces the pinion, a free wheel device and a stator rotor in which the pinion cooperates, a locking device which prevents a pre-engagement of the pinion in an unexcited state of the engaging relay. The locking device has a stationary locking element which engages behind a part actuated by the armature for securing a rest position of the pinion. The armature has a tappet on which a control sleeve is arranged. The locking element is formed as a first spring provided with at least one undercut step and deflectable in a release position by the control sleeve arranged on the tappet of the armature.
