Abstract
In order to provide a belt drive for a motor-driven tool with a first, drive-side belt pulley, a second, tool-side belt pulley and a belt that can be tensioned over the first and the second belt pulley, that is characterized by being easier to use, it is proposed that a cam, rigidly connected with a shaft, is arranged in the first or second belt pulley, whereby during a rotational movement of the shaft the belt pulley can be moved from an eccentric arrangement in relation to the shaft into a concentric arrangement by way of a translational movement and a rotational movement of the belt pulley.
