The present invention relates to the construction of a combustion nozzle for a gas lighter, and more particularly to the construction of a nozzle provided with an inner automatic shutting-off device, wherein a second valve provided in a nozzle rod, for blocking a blocking portion through the action of a shape memory member, is equipped with a push-back portion for being resiliently deformed to urge the shape memory member in a direction of pushing it back when the blocking portion is blocked. With this arrangement, a return spring can be dispensed with to reduce the number of parts, and the shape memory member such as a shape memory alloy can be satisfactorily restored without giving it the bidirectional property. |
