Abstract

The invention relates to a hand tool machine (2), in particular a drilling and/or percussion hammer, with a housing (4) and a vibration-damped handle (10) elastically supported relative to the housing (4) with two essentially parallel legs (20, 22) and a coupling element (44 or 46) between each leg (20 or 22) and the housing (4) that is pin-jointed to the leg (20 or 22) and the housing (4). The coupling elements (44, 46) are connected to each other by a connector (48) that synchronizes the movements of the coupling elements (44, 46).
