PURPOSE:To prevent dispersion of vaporized fuel to the atmosheric air during the feed of fuel, by a method wherein a canister, adsorbing the vaporized fuel, is installed on a freezer passage, and a valve, opened during the fed of the fuel, is situated in the upper stream side of the canister. CONSTITUTION:An oil feed gun 11 is inserted into an oil feed port 2, and the oil feed port 2 is sealed to feed fuel. In which case, since, when a cover body 32 of the oil feed port 2 is opened, a solenoid valve 31 is already opened, air and vaporized fuel in a fuel tank 1 and an inlet pipe 3 flow through passages 24 and 27 to an introduction port 34 along with the feed of the fuel. The vaporized fuel is adsorbed by active coal 47, and only clean air is exhausted through an opening 48 to the open air. The liquid level of the fuel is raised up to a passage opening 21, a fuel liquid level 28 is raised to a passage 24 and the forward end of the oil feed gun 11 to actuate the auto stopper of the oil the feed gun 11 to actuate the auto stopper of the oil feed gun 11, the feed of the fuel is completed, and the cover body 32 of the oil feed port 2 is closed to close the solenoid valve 31. |
