Abstract
A driver includes a housing in which an accumulator for accumulating compressed air is provided; a trigger provided in the housing; a cylinder stored in the housing; a piston stored to be slidable in the cylinder and driven by the compressed air; and a head valve moving in response to movement of the trigger between an acting position which is distant from the cylinder so that the compressed air acts on the piston and a blocking position which abuts against the cylinder so that the action of the compressed air on the piston is blocked. The cylinder can be arranged at a first position and a second position closer to the head valve than the first position in a state that the head valve moves from the blocking position to the acting position.
