Abstract
An impact tool includes a motor, a rotating shaft rotationally driven by the motor, a swinging member that swings in an axial direction of a tool bit by rotation of the rotating shaft, a tool driving mechanism connected to an end region of the swinging member in a direction transverse to the axis of the rotating shaft. The tool driving mechanism is moved rectilinearly in the axial direction of the tool bit by swinging movement of the swinging member thereby rectilinearly driving the tool bit. A vibration reducing member reduces vibration caused in the axial direction of the tool bit during operation of the tool bit. The vibration reducing member is disposed on an opposite side of a rectilinear working axis of the tool bit from the rotating shaft and connected to a connecting part between the swinging member and the tool driving mechanism so as to be driven.
