To suppress the generation of stress when purge piping is thermally expanded and thermally contracted, and to suppress the positional displacement of the purge piping.SOLUTION: Purge piping 20 includes resin-made floor lower piping 20a which is supported by two pieces of clamps 32 fixed to a floor of a cabin, and extends to a vehicle fore-and-aft direction below the floor. The floor lower piping 20a has paired salient parts 36 which are arranged at both sides of two pieces of the clamps 32, and salient from a surface of the floor lower piping 20a. An interval between the paired salient parts 36 is wider than width dimensions of the clamps 32. Furthermore, the floor lower piping 20a is located between two pieces of the clamps 32, and has a bent part 38 which is bent and protrudes to a lateral direction of the floor lower piping 20a.SELECTED DRAWING: Figure 3

    【課題】パージ配管が熱膨張および熱収縮するときの応力の発生を抑制し、またパージ配管の位置ずれを抑える。【解決手段】パージ配管20は、車室のフロアに固定された2個のクランプ32で支持され、フロア下を車両前後方向に延びる樹脂製のフロア下配管20aを含む。フロア下配管20aは、その軸線方向において、2個のクランプ32のそれぞれの両側に配置され、フロア下配管20aの表面から隆起した対をなす隆起部36を有する。対をなす隆起部36は、それらの間隔がクランプ32の幅方向寸法より広い。さらに、フロア下配管20aは、2個のクランプ32の間に位置し、屈曲してフロア下配管20aの横方向に突出した屈曲部38を有する。【選択図】図3
