Abstract
To improve convenience of a working machine. A driver 10 includes a striking portion 12, a pin wheel 50 that rotates by a driving force of an electric motor, and a control unit that controls the electric motor. The pin wheel 50 has a plurality of rotating portion-side engagement portions, and the striking portion 12 has a plurality of striking portion-side engagement portions. The striking portion 12 moves upward when the pin wheel 50 rotates in an engaged state where the rotating portion-side engagement portion and the striking portion-side engagement portion is engaged with each other. The control unit determines whether or not the plurality of striking portion-side engagement portions and the plurality of rotating portion-side engagement portions have a predetermined engagement relationship in a striking operation.
