Abstract
A portable handheld motor-driven tool such as a brushcutter or the like drives a work tool via a drive shaft. The drive shaft is coupled to the motor shaft and is journalled in the motor housing by means of damping member. The respective longitudinal axes of the motor shaft and drive shaft are displaced with respect to each other to prevent vibrations during operation of the motor-driven tool.
