ABSTRACT:
A gas lighter is provided which is highly reliable and cannot release fuel gas even when its actuation member is depressed, as long as a child resistant locking device has not been moved to its unlocking position. The gas lighter includes a fuel-supplying device for supplying fuel gas to a nozzle through a valve mechanism, an action lever, which must be rotated about a rotation axis to open and close the valve mechanism of the fuel-supplying device, an igniter for igniting fuel gas discharged through the nozzle, and the actuation member, which when depressed drives the igniter. An unlocking member is normally held in a locking position where it holds the rotation axis of the action lever in a first position where depression of the actuation member cannot rotate the action lever to open and close the valve mechanism. The unlocking member is movable to an unlocking position to move the rotation axis of the action lever to a second position where rotation of the action lever by the actuation member can open and close the valve mechanism.
