Claim:
1. A power tool comprising: a motor; a drive unit driven by the motor; a trigger switch operable by a user and switchable between an activation state, in which the motor is driven, and a deactivation state, in which the motor is stopped; a forward-reverse switch operable by the user and used to switch a motor rotation direction between a forward rotation direction and a reverse rotation direction; and a control unit that drives the motor based on an operation of the trigger switch, wherein the control unit is adapted to allow a mode shifting switch of the power tool to be switched between a first mode and a second mode; wherein in the first mode, the control unit switches the motor rotation direction to a rotation direction that is selected by the forward-reverse switch, in the second mode, when the trigger switch is switched from the activation state to the deactivation state, the control unit switches the motor rotation direction so that the motor is driven in a rotation direction opposite to the present rotation direction when the trigger switch is activated next, and in the second mode, when the trigger switch continues to be in the activation state, the control unit continuously drives the motor in the present rotation direction.
