PROBLEM TO BE SOLVED: To enable gas in a fuel tank to flow to a canister even when a fuel surface is tilted in the fuel tank and to enlarge effective capacity of the fuel tank.SOLUTION: A fuel tank system comprises: communication piping 30 which has a plurality of opening sections 54A and 54B positioned above a maximum fuel level in a fuel tank 14 and communicates an inside of the fuel tank 14 with a canister 32; and a valve member 42 which is arranged outside the fuel tank 14 and, on the basis of a tilt state of fuel detected by a fuel tilt sensor 60, closes the communication piping corresponding to the opening section predicted to be positioned under fuel and opens the communication piping corresponding to the opening section predicted to be positioned in a gas phase section.SELECTED DRAWING: Figure 1A

    【課題】燃料タンクの燃料液面傾斜時に燃料タンクからキャニスタへの気体の移動が可能で、且つ燃料タンクの実効容量を大きく確保する。【解決手段】燃料タンク14の内部で満タン液位より上に位置する複数の開口部54A、54Bを備え燃料タンク14の内部とキャニスタ32とを連通する連通配管30と、燃料タンク14の外部に設けられ、燃料傾斜センサ60で検出した燃料の傾斜状態に基づいて燃料中に位置すると予測された開口部に対応する連通配管を閉塞し気層部分に位置すると予測された開口部に対応する連通配管を開放する弁部材42と、を有する。【選択図】図1A
