Abstract

A starter device for an internal combustion engine (10) has an actuating device and an entrainer (24) can be coupled to the crankshaft (13) of the engine (10). The entrainer (24) and the actuating device are rotatably journalled about a rotational axis (14). The entrainer (24) and the actuating device are connected to each other via a damping spring (23). The damping spring (23) is connected with a first end (26) to the actuating device and with a second end (27) to the entrainer (24). The entrainer (24) and the actuating device have respective supports (21, 42). The damping spring (23) is mounted on the outer periphery of the two supports (21, 42). In the direction of the rotational axis (14), a disc (22) is mounted between the two supports (21, 42) in order to avoid the situation that the damping spring (23) can force itself into a gap between the two supports (21, 42) which gap can arise during operation.
