固定される。 The heat resistant member 12 is made of graphite, and has a through hole 20 through which the pipes 18 and 19 are inserted. By fitting this heat-resistant member 12 into the gun barrel 17, the gun barrel 17 is covered with the heat-resistant member 12. A nozzle tip is located on the end surface of the heat-resistant member 12. Mixture chamber 16
and the heat-resistant member 12 are fixed by screw connection or other connection means.
