ABSTRACT:
An electric driving machine has a motor for rotating a flywheel, power transmission for converting rotational drive force of the flywheel into rectilinear drive force and transmitting the rectilinear drive force to an actuator which fires a fastener, and engagement/disengagement arrangement which transmits the rotational drive force of the flywheel to a driver blade of interrupts transmission of the rotational drive force. The electric driving machine is provided with a second switching element connected in series with the engagement/disengagement arrangement and a third switching element connected in shunt with the engagement/disengagement arrangement. When a push lever switch is in an OFF position where driving of a fastener is not ready, the third switching element is held in an ON state.
