Description

[Technical field]

[0001] The present invention relates to a cutting device, in particular a chain saw and associated drive wheel, according to the preambles of the independent claims. [Background technology]

[0002] From the prior art, a large number of chainsaws are known which have a drive wheel for the saw chain.

However, a drawback of such cutting devices is that the saw chain vibrates perpendicularly to the direction of movement during the switching-on and cutting processes. This vibration can cause the saw chain to move back and forth, which causes it to stretch and shortens its lifespan. Summary of the Invention [Problem to be solved by the invention]
