Abstract:
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
