To provide a fuel tank device that is able to stably supply fuel to an engine while efficiently supplying the fuel from a sub-tank to a main tank.SOLUTION: A fuel tank device including a plurality of fuel tanks configured to supply fuel to an internal combustion engine of a vehicle, comprises: a main tank having a suction port configured to supply the fuel to the internal combustion engine; a sub-tank configured to supply the fuel to the main tank; and a connection pipe allowing communication between the main tank and the sub-tank and configured to supply the fuel from the sub-tank to the main tank. In the main tank, the connection pipe has a first opening at an end and has a plurality of second openings, smaller than the first opening, on a peripheral surface, and the plurality of second openings are disposed in the vicinity of the suction port.SELECTED DRAWING: Figure 2

    【課題】サブタンクからメインタンクへ効率よく燃料を供給しつつ、安定的にエンジンへ燃料を供給することができる燃料タンク装置を提供すること。【解決手段】車両の内燃機関に燃料を供給するため複数の燃料タンクを備える燃料タンク装置であって、前記内燃機関へ前記燃料を供給する吸い込み口を有したメインタンクと、前記メインタンクへ前記燃料を補給するためのサブタンクと、前記メインタンクとサブタンクとを連通し、前記サブタンクから前記メインタンクへ燃料を供給する供給ポンプを備えた接続管と、を備え、前記接続管は、前記メインタンク内において、端部に第1開口部が設けられており、且つ、周面に前記第1開口部より小さな複数の第2開口部が設けられ、前記複数の第2開口部は前記吸い込み口の近傍に配置されている。【選択図】図2
