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

The invention relates to an eccentric drive ( ) and especially to an eccentric drive for a portable handheld work apparatus having a wheel ( ) driven by a drive motor ( ). A cam ( ) is eccentrically fixed to an end face ( ) of the wheel ( ). The cam ( ) is held by a connecting rod ( ) and cylinder-shaped roller bodies ( ) are mounted between the connecting rod ( ) and the cam ( ). The roller bodies ( ) have axial ends ( ) which engage in an annular slot ( ) of the wheel ( ). A holding element ( ) is disposed on the cam ( ) and limits the axial play of the roller bodies ( ).
