Abstract

A starter device for an internal combustion engine has an entrainer for coupling to the engine. The entrainer and an actuator of the starter device are mounted rotatably about a rotational axis. A damper spring is arranged between and operatively connects the entrainer and the actuator to each other. The starter device has at least one stud, on whose outer periphery the damper spring is mounted. The damper spring is a hinge spring wound from a spring wire. The cross section of the spring wire is rounded on the inner side of the spring wire. At least a portion of the cross section runs linearly on the outer side of the spring wire.
