Abstract
A starter device for an internal combustion engine has a drive element and a output element. The drive element enables driving the starter device in rotation. The output element is supported rotatably about an axis of rotation and has a coupling device for releasably coupling the starter device to the crankshaft. A coil spring is arranged operatively between drive element and output element in an axial direction between a first abutment at the drive element and a second abutment at the output element. The first and second abutments have a first spacing relative to one another at least at one circumferential location in a first area and a second spacing relative to one another in a second area. The first and second spacing are measured parallel to the axis of rotation. The first spacing is smaller than the second spacing. The first area is radially outside of the second area.
