To inhibit discharge of vapor to the air during fueling in a fuel tank device for a vehicle that is configured as a dual tank system.SOLUTION: The present invention is a fuel tank device 1 for a vehicle, in which a fuel supply pipe 10 is branched into two, and the two branched pipe portions 12, 13 are connected to a first fuel tank 20 and a second fuel tank 30, respectively. A main pipe portion 11 of the fuel supply pipe 10 before the fuel supply pipe 10 is branched,is provided with a resistance portion 3 that forms a flow filling the cross section of a flow path of the main pipe portion 11 with gasoline G by providing resistance for the gasoline G flowing in the main pipe portion 11.SELECTED DRAWING: Figure 1

    【課題】デュアルタンクシステムとして構成された車両の燃料タンク装置において、給油中におけるベーパーの大気への放出を抑制する。【解決手段】燃料供給パイプ10が二股に分岐し、これら分岐した2本の分岐パイプ部12,13がそれぞれ第1燃料タンク20と第2燃料タンク30とに接続される車両の燃料タンク装置1である。燃料供給パイプ10における分岐する手前の主パイプ部11には、主パイプ部11内を流れるガソリンGに抵抗を付与することで、主パイプ部11の流路断面がガソリンGによって満たされるような流れを形成させる抵抗部3が設けられている。【選択図】図1
