PURPOSE:To prevent the leakage of mixture regardless of the existence of thermal strains by a method wherein the titled combustion device is provided with an ejector, inducting fuel and air in a fuel and air supplying body into a first mixing chamber and air, supplied from an air supplying body, is switched to the ejector or a fuel and air supplying body. CONSTITUTION:When the amount of combustion is increased, a switching means 17 is operated to switch the ventilation of an air supplying body 3 into the side of a fuel and air supplying body 4. When the amount of combustion is decreased, the switching means 17 is operated to switch the ventilation of the air supplying body 3 into the side of an ejector 16. Fuel and air in the fuel and air supplying body 4 is induced to send it into a first mixing chamber 5 by the ejector effect of the ejector. In this case, the inside of the fuel and air supplying body 4 has a negative pressure with respect to an atmosphere, therefore, the flow of air is generated from atmosphere through a second mixing chamber 6 and a second communicating path 15 and the air is sent into the first mixing chamber 5. Accordingly, there is notching to blockage mixture and the mixture will never leak into the second mixing chamber even when the flow of mixture into the second mixing chamber is prevented by utilizing the flow of fluid due to a pressure difference and thermal strains are generated in respective places.
