A device for driving nails and similar fastening elements includes a driver rod performing a reciprocating stroke-like movement for placing the nails. A rotating driving element transmits the driving power to the driver rod so that it carries out the stroke-like movement. During the nail driving operation, the rotating driving element is coupled with the driver rod by a carrier. The carrier is secured to the driving element and moves along an elongated path in converting the rotational movement of the driving element into the stroke-like movement of the driver rod.
