An electric power tool includes a motor (20) that rotary drives an output shaft; an operation unit (30) to input a drive command of the motor (20); a torque setting device (40) that sets an upper limit value of a rotational torque of the output shaft in accordance with a torque setting command; and a control device (40) that drives the motor (20) in one of a forward direction and a reverse direction in accordance with the drive command, and stops driving of the motor (20) when the rotational torque of the output shaft has reached the upper limit value set by the torque setting device (40) during driving of the motor (20). The torque setting device (40) is configured to set the upper limit value such that the upper limit value during driving of the motor (20) in the forward direction and the upper limit value during driving of the motor in the reverse direction are different. |
