PROBLEM TO BE SOLVED: To provide a fuel tank for automobile which absorbs a rise and a drop of an internal pressure of a fuel tank for automobile.SOLUTION: In a fuel tank 1 for automobile having a tank outer wall 7 formed of a thermoplastic synthetic resin, beads 10 are formed so as to project from the tank outer wall 7 to the inside of the fuel tank 1, and at least two beads are integrally formed in parallel with each other. A cross-sectional shape of the beads 10 has an approximately triangle shape, and an angle X formed by one inclined surface 21 of the beads 10 and the tank outer wall 7 is formed so as to be smaller than an angle Y formed by the outer inclined surface 22 and the tank outer wall 7.SELECTED DRAWING: Figure 3

    【課題】自動車用燃料タンクの内圧の上昇と下降を吸収する自動車用燃料タンクを提供する。【解決手段】熱可塑性合成樹脂で形成されたタンク外壁7を有する自動車用燃料タンク1において、タンク外壁7から燃料タンク1の内側に突出してビード10を形成し、ビードは一体的に平行して少なくとも2本形成される。ビード10の断面形状は略三角形で、ビード10の一方の斜面21とタンク外壁7とのなす角度Xは、他方の斜面22とタンク外壁7とのなす角度Yよりも小さく形成された。【選択図】図3
