To provide a pipe attachment structure of a fuel tank by which a pipe attachment member can be formed simultaneously with formation of the fuel tank, and the pipe attachment member can be surely formed, in the pipe attachment structure of the fuel tank.SOLUTION: In a pipe attachment structure of a fuel tank having a pipe attachment part 20 for attaching a pipe to an outer wall 10 of the fuel tank, the fuel tank has the pipe attachment part 20 extending in an external direction of the fuel tank integrally from the tank outer wall 10. The pipe attachment part 20 has an attachment part outside wall 21 which is integrally, continuously and cylindrically extended in the external direction from the tank outer wall 10, and formed of the same material as that of the tank outer wall 10, and an attachment part inside wall 22 which is bent into a hairpin shape continuously from a leading end of the attachment part outside wall 21, and formed inside the attachment part outside wall 21. The attachment part outside wall 21 and the attachment part inside wall 22 are formed so as to tightly adhere to each other.SELECTED DRAWING: Figure 3

    【課題】燃料タンクのパイプ取付構造において、パイプ取付部材を燃料タンクの成形と同時に成形するとともに、確実にパイプ取付部材を成形することのできる燃料タンクのパイプ取付構造を提供する。【解決手段】燃料タンクのタンク外壁10にパイプを取付けるパイプ取付部20を設ける燃料タンクのパイプ取付構造において、燃料タンクは、タンク外壁10から一体的に燃料タンクの外方向に延出されたパイプ取付部20を有する。パイプ取付部20は、タンク外壁10から外方向に一体的に連続して円筒状に延出されタンク外壁10と同一材料で形成される取付部外側壁21と、取付部外側壁21の先端から連続してヘヤピン状に屈曲して取付部外側壁21の内側に形成される取付部内側壁22を有し、取付部外側壁21と取付部内側壁22が密着して形成されている。【選択図】図3
