A technique for further improving vibration reducing performance is provided in an impact tool that rectilinearly drives a tool bit in an axial direction of the tool bit via a swinging member. An impact tool includes a motor 111, a rotating shaft 125 rotationally driven by the motor 111, a swinging member 129 that swings in the axial direction of a tool bit 119 by rotation of the rotating shaft 125, a tool driving mechanism 141, 143, 145 that is connected to an end region of the swinging member 129 in a direction transverse to the axis of the rotating shaft 125, and is caused to rectilinearly move in the axial direction of the tool bit 119 by swinging movement of the swinging member 129, thereby rectilinearly driving the tool bit 119, and a vibration reducing member 151 for reducing vibration caused in the axial direction of the tool bit 119 during operation of the tool bit 119. The vibration reducing member 151 is disposed on an opposite side of a rectilinear working axis of the tool bit 119 from the rotating shaft 125 and connected to a connecting part between the swinging member 129 and the tool driving mechanism 141, 143, 145 in such a manner as to be driven. |
