PURPOSE:To make it possible to simply carry out cleaning of a pilot nozzle by operating a nozzle cleaning needle in linkage with a knob shaft for extinguishment in a push-type gas plug. CONSTITUTION:By pushing the knob shaft 26 for fire extinguishment, a lever 44 operating in linkage therewith inclines with respect to a fulcrum (g) as a center, and a lever 49 inclines with respect to a fulcrum (h) by a tension spring 50 disposed at the tip end of the lever 44 so as to push up a spring shoe 48 fitted to the nozzle cleaning needle 41, and the nozzle cleaning needle 41 to clean a pilot nozzle 38. By providing two springs, and two fulcrums, the operation can be positively performed, and cleaning of the nozzle can be performed every time the knob shaft 26 is pushed. |
