Abstract: An impact tool performs a processing operation on a workpiece by carrying out an impact operation on a tool bit in a longitudinal axis direction. The impact tool includes a motor having a rotor and a stator, a tool main body housing the motor, a drive shaft parallel to a longitudinal axis of the tool bit and rotatably driven by the motor, and an oscillating member that is supported by the drive shaft and that carries out an oscillating movement in the axial direction of the drive shaft based on the rotational motion of the drive shaft. A tool drive mechanism is coupled to the oscillating member so that the oscillating movement of the oscillating member linearly moves the tool bit in the longitudinal axis direction. The motor is an outer rotor motor in which the rotor is disposed on an radially outer side of the stator.
