Abstract

A hand-held power tool includes a main element with a normal axis which extends perpendicularly to a tool axis and through a center of gravity. A handle is supported in the plane of motion defined by the tool axis and the normal axis such that it is movable relative to the main element. A spring unit connects the handle with the main element, and has a spring element to define a trajectory of at least one portion of the handle in the plane of motion under the influence of a load force triggered when the handle is moved out of a neutral position and approaches the stationary main element. A rotary element defines a joint-free rotation axis, about which the handle rotates in the plane of motion when a motion takes place relative to the main element.
