PROBLEM TO BE SOLVED: To ensure durability while ensuring the freedom of design of a fuel tank.SOLUTION: An inlet lower pipe 20 comprises an internal projection 20A projecting inside a tank body 18 and an external projection 20B projecting outside the tank body 18. One part of a connection member 16 in a longitudinal direction is a tank insertion part 22 to be inserted into the inlet lower pipe 20 in a fluid-tight manner, and the other part of the connection member 16 is a pipe connection part 24 to be connected to the filler pipe 14 in the fluid-tight manner. A non-return valve 34 is provided at a tip of the tank insertion part 22. When the tank insertion part 22 of the connection member 16 is connected to the inlet lower pipe 20 in the fluid-tight manner, a length (area) of a portion for supporting the tank insertion part 22 with the inlet lower pipe 20 is ensured, thereby suppressing a projection amount of the inlet lower pipe 20 to the outside of the fuel tank 10.

    【課題】耐久性を確保しつつ燃料タンクの設計の自由度を確保する。【解決手段】インレットロアパイプ20は、タンク本体18内に突出する内部突出部20Aと、タンク本体18外に突出する外部突出部20Bとを有している。結合部材16の長手方向の一方の部分は、インレットロアパイプ20に液密に挿入されるタンク挿入部22とされ、結合部材16の長手方向の他方の部分は、フィラーパイプ14に液密に結合されるパイプ結合部24とされ、タンク挿入部22の先端に逆止弁34が設けられている。結合部材16のタンク挿入部22をインレットロアパイプ20に液密に結合した場合に、インレットロアパイプ20がタンク挿入部22を支持する部分の長さ(面積)が確保され、インレットロアパイプ20の燃料タンク10の外方への突出量を抑制できる。【選択図】図2
