Abstract
A device for driving a drilling and/or impacting tool including a shaft journalled in a housing so as to be rotatable, if necessary. One end of the shaft is connectable with the tool whereas the other end is accessible for an oscillatory impact body movable in the housing by a guide, a rotatable driving shaft setting and a transmission. The transmission includes a device for converting the rotary movement of the driving shaft into an oscillatory movement of a driving element which is connected through an elastic member with the impact body.
