PURPOSE: To prevent fuel supply from becoming impossible due to a pressure drop by taking out liquefied fuel from a liquefied gas fuel storage container still in a liquid shape, and arranging a fuel passage to supply the fuel to a mixer so as to be heated by means of generated heat and so on of an engine in itself.
CONSTITUTION: A fuel supply device 200 is composed of a fuel storage container 210, a liquefied fuel taking out means 600, a liquefied fuel heating means 700, a liquefied fuel passage 620, pressure governing valves 231 and 232 and a mixer 240. The fuel storage container 210 stores liquefied gas fuel 300 in coexistence of liquid phase and gaseous phase. The fuel taking out means 600 takes out the liquefied gas fuel 300 still in a liquid shape. The liquefied gas fuel 300 is vaporized while flowing in the liquefied fuel passage 620 arranged so as to be heated by means of generated heat of an engine in itself or a heating heater, and is flowed into the mixer 240 in a gaseous state. Thereby, since pressure in a liquefied fuel storage tank is not changed, fuel supply becomes hardly impossible due to a pressure drop in the fuel storage container 210.
