摘要： PROBLEM TO BE SOLVED: To provide a fuel tank structure which can suppress opening of a fill-up regulation valve because a gas flow from a fuel tank acts on the fill-up regulation valve in a state that the inside pressure of the fuel tank is high.SOLUTION: In a fuel tank 14, there is provided a cross section variable valve 60 which reduces the cross section of a gas passage when the flow rate in the valve opening direction toward a float 44 of a fill-up regulation valve 24 increases. A barrier 50A is arranged between the through passage 64C of the cross section variable valve 60 and the float 44.
