POWER TOOL

A power tool configured to stabilize the rotational speed of a motor is provided. A power tool (1) includes a motor (4), a trigger (3), a pressure sensing unit (7), and a control circuit (5). The motor (4) is configured to receive electric power from a battery (241) to rotate a socket (212). The trigger (3) is movably held by a tool body (2). The pressure sensing unit (7) includes a pressure receiving unit (71) for receiving pressure according to a pull-in amount of the trigger (3) and is configured to measure a magnitude of the pressure received with the pressure receiving unit (71). The control circuit (5) is configured to control a rotational speed of the motor (4) based on measured pressure measured by the pressure sensing unit (7). The control circuit (5) is configured to perform hysteresis control of the rotational speed of the motor (4) such that the rotational speed of the motor (4) with respect to the measured pressure differs between a case where the measured pressure increases with time and a case where the measured pressure decreases with time.
