The present invention at least one of the impact mechanism, the guide surface having, has, in the receiving bore inner diameter relates to a percussion device having the impact mechanism comprising: a housing having a receiving bore which is equipped with a percussion piston so as to be movable along the longitudinal axis is formed, and the percussion piston on, at least one of the percussion piston guide surface is formed having an outer diameter. To the radial contact between the impact piston and the impact mechanism housing avoided as much as possible, to reduce the amount of the oil leakage through the gap between the guide surface, and in order to prevent wear on the lands between the wear and the seal on the guide surface, According to the invention, the impact mechanism, the guide surface has a diameter that increases non-linearly in the axial direction at least in some areas, and / or the percussion piston guide surface has an outer diameter that decreases in a non-linear in the axial direction.
