PURPOSE:To enable compacting of constitution, to facilitate assembly, and to improve ignition performance, by a method wherein a projection is provided on a gas cock body, an ignition burner is engaged therewith, and in order to prevent the occurrence of displacement, the ignition burner is located in a manner to make plane contact with a gas cock to securely mount them by a screw tightening way. CONSTITUTION:A projection part (a) for engaging with an ignition burner 3 is formed on a gas cock 1, and a securing screw tightening part (b) is located on the same straight line as the straight line on which ignition nozzle 2 is situated. This reduces axial vibration of the ignition nozzle 2 and the ignition burner 3. The ignition burner 3 is secured to the gas cock 1 in a manner to make plane contact with the gas cock, and thereby the ignition burner 3 is decreased in vertical vibration. Further, the ignition nozzle 3 makes direction contact with a gas cock body, and this reduces incurring of a flow rate loss and improves ignition performance. |
