PROBLEM TO BE SOLVED: To provide a fuel tank in which an integrated component, which has high rigidity and is easily manufactured, can be fitted inside the fuel tank.SOLUTION: In a fitting structure of an integrated component 20 of an automobile fuel tank 1 to which the integrated component 20 is fitted inside and which has an outer wall made of a synthetic resin, the integrated component 20 comprises: an upper contact part 21 and a lower contact part 22 in which the integrated component 20 is fused and fitted to upper and lower inner surfaces of a tank outer wall 10 of a fuel tank 1; and a body part 23 connecting the upper contact part 21 and the lower contact part 22. The upper contact part 21 and the lower contact part 22 have an upper welding surface 21a and a lower welding surface 22a welded to the inner surface of the tank outer wall 10, respectively. Outer wall inner surface projection parts 18 projecting to the inside of the fuel tank are formed on the tank outer wall 10. Planar outer wall inner surface welding surfaces 17 are formed on surfaces of the outer wall inner surface projection parts 18, which face the upper welding surface 21a and the lower welding surface 22a.SELECTED DRAWING: Figure 6
【課題】剛性が大きく、製造が容易な内蔵部品を燃料タンク内に取付けることができる燃料タンクを提供する。【解決手段】内部に内蔵部品20を取付けられ、合成樹脂で形成された外壁を有する自動車用燃料タンク1の内蔵部品20の取付構造において、内蔵部品20には、燃料タンク1のタンク外壁10の上下の内面に融着して内蔵部品20を取付ける上部当接部21と下部当接部22、及び上部当接部21と下部当接部22を接続する本体部23を有する。上部当接部21と下部当接部22は、それぞれタンク外壁10の内面に溶着される上部溶着面21aと下部溶着面22aを有する。タンク外壁10は、燃料タンク内側に突出する外壁内面突出部18が形成され、外壁内面突出部18の上部溶着面21aと下部溶着面22aと対向する面は、平面状の外壁内面溶着面17が形成された。【選択図】図6
