Abstract
A driving tool includes a flywheel, a driver held to be movable between an initial position and a driving position along an movement axis, a ring member configured to transmit rotational energy of the flywheel to the driver, and a driver moving mechanism configured to move the driver with respect to the ring member from the initial position to a transmitting position. When the driver is placed in the initial position, the ring member is disposed loosely around the outer periphery of the flywheel. When the driver is moved to the transmitting position by the driver moving mechanism, the ring member is frictionally engaged with the driver and with the flywheel, rotated by the flywheel, and transmits the rotational energy to the driver, thereby pushing the driver from the transmitting position toward the driving position.
