Abstract
A piezoelectric gas lighter includes a lighter body. The fuel gas in the lighter body is supplied to a nozzle through a valve mechanism which is opened and closed by an actuator lever and a piezoelectric unit ignites the fuel gas discharged from the nozzle. A depression member actuates the actuator lever and the piezoelectric unit to open the valve mechanism and ignite the fuel gas discharged from the nozzle in response to depression of the depression controller. The depression member includes a control cap operatively connected to a piezoelectric unit, a stopper member which is movable between a locking position where the control cap is prevented from being depressed and a releasing position where the control cap is permitted to be depressed and an urging member which urges the stopper member to the locking position. The stopper member is provided with a pair of sliding portions extending back and forth on opposite sides of the control cap and the sliding portions are slidably supported by the control cap so that the stopper member is movable downward together with the control cap and movable between the locking position and the releasing position. The urging member includes a pair of resilient pieces provided on opposite sides of the control cap so that they are engaged with the sliding portions of the stopper member to urge the stopper member to the locking position and the stopper member is moved to the releasing position by urging the stopper member toward the control cap.
