Abstract

A hand-held power tool, in particular an impact driver, an impact drill, or a rotary hammer, is proposed, which has a drive unit and/or output with at least one line of action, which produces at least oscillations along the line of action. In order to reduce these oscillations, the hand-held power tool is equipped with at least one vibration absorber unit. The vibration absorber unit has at least one mobile vibration absorbing element, which has at least one degree of freedom of movement. This degree of freedom of movement encloses at least one angle not equal to zero with the line of action.
