PROBLEM TO BE SOLVED: To supply fuel to cavity sections which can have relatively small spaces and a flow passage through which an air flow is fed to a cavity section by making the fuel to be fed to the flow passages formed in a dome inlet module or the cavities through a fuel injector bar. SOLUTION: Fuel is only fed from the injection nozzle of a fuel injector bar 50 and air is also blown into cavities 40 and 42 through passages 92 and 94 respectively provided at the intersections of a rear wall and external and internal walls and a passage 96 provided at the intersections of a front wall and the external and internal walls. Consequently, the trapped vortexes of the fuel and air are formed in the cavities 40 and 42. Thereafter, the air-fuel mixed gases in the cavities 40 and 42 are ignited by means of, for example, an igniter 100 and combustion gases are produced in the cavities 40 and 42. Thereafter, the combustion gases are discharged from the cavities 40 and 42 across the downstream end of a dome inlet module 20 and interacts with the main-flow air flowing through a flow passage 38.
