Abstract
A driver includes: a pressure chamber and a striking portion actuated in a direction of striking a fastener when compressed gas is supplied to the pressure chamber, and can select a single firing and a continuous firing; a switching mechanism having a first actuated state to actuate the striking portion in the direction when the single firing is selected and a second actuated state to block the striking portion from being actuated in the direction when the continuous firing is selected; and a control unit configured to switch the switching mechanism from the first actuated state to the second actuated state when a predetermined time elapses in a state where the continuous firing is selected and the switching mechanism is in the first actuated state. The control unit stops the power supply to the switching mechanism for at least part of a period of time when the predetermined time elapses.
