1. A driving tool, comprising:
a driving passage that extends along a first end surface of a tool main body;
a driver that is movable along the driving passage;
a lift mechanism configured to move the driver from a bottom dead center to a standby position and from the standby position to a top dead center;
a pusher configured to push a driving member from a side opposite to the first end surface such that the driving member contacts a tip end of the driver at the standby position; and
an idling strike prevention mechanism configured to interlock with a position of the pusher, wherein:
the pusher pushes the driving member to the driving passage into a driving position when the driver moves from the standby position to the top dead center, thereby the driving member being driven by the driver that moves to the driving position;
the pusher moves to an activation restriction position when no driving member is left in order that the idling strike prevention mechanism restricts activation of the driving tool-;
the idling strike prevention mechanism includes (i) a contact arm that is movably attached to the tool main body for activating the lift mechanism by contacting a workpiece to move to an on position, and (ii) a stopper having an engagement portion that engages the contact arm to restrict the contact arm from moving to the on position when the pusher moves to the activation restriction position;
the idling strike prevention mechanism includes a relative moving mechanism by which the stopper is movable relatively to the pusher in a pushing direction in which the pusher moves to a side of the first end surface;
the relative moving mechanism includes a biasing member between the stopper and a stopper holding portion that holds the stopper, the biasing member biasing the stopper toward the driving passage with respect to the stopper holding portion; and
the pusher is formed integrally with the stopper holding portion.
