PROBLEM TO BE SOLVED: To improve combustion efficiency by quickly and uniformly generating mixed gas of fuel and air. SOLUTION: This device is provided with a tank 1 to store gasoline G forcedly fed by air from a pump 13, a generator pipe 3 communicating a gas injection nozzle 8 disposed on a lower part of a burner 5 and the tank 1 via a gas quantity regulator 2, and a suction valve 15 for generating mixed gas connected to the generator pipe 3 and inserted into the tank 1. The suction valve 15 is constituted of an internal pipe 15c connected to a flow passage of a connecting joint 15a fitted airtightly and watertightly into a suction port 14 provided on the tank 1, an external pipe 15d surrounding the internal pipe 15c with a gap S between the external pipe 15d and the internal pipe 15c, provided with an air introduction port 15k on an upper end side and extending downward from a lower end of the internal pipe 15c, and a suction member 15i with a filter 15h fitted into a lower end opening part of the external pipe 15d.
