Patent ID: 7690277

Claim:
A starting device for an internal combustion engine for hand-held tools, chainsaws, lawnmowers, trimmers, comprising: a rotatable pulling medium roller connected to a drive plate on a crankshaft of the internal combustion engine for initiating a rotational movement in the drive plate and crankshaft; a deformation body formed as a rubber elastic body extending between the pulling medium roller and the drive plate thereby making the connection between the pulling medium roller and the drive plate rotational and elastic, wherein the pulling medium roller, the drive plate and the deformation body share a common axis of rotation and the deformation body has a star-shaped outer contour; and a first recess in the pulling medium roller and a second recess in the drive plate, each recess having a star-shaped inner contour into which the star-shaped outer contour of the deformation body fits, in order to create a positive transmission of the rotational movement between the pulling medium roller and the drive plate.
