To perform attaching step to a bellows structure of cylinder piping in a shorter time than a conventional one, when the bellows structure holds the cylinder piping.SOLUTION: An air guiding duct 50 has a square cylindrical shape, is provided between a radiator 10 and a front grille 15 provided in front of the radiator 10, and is extended in a vehicle fore-and-aft direction so as to surround a front surface 12 of the radiator 10. ON a pipe wall configuring a part of the square cylinder shape of the air guiding duct 50, a holding portion 70 holding a radiator hose 30 that is cylindrical piping is provided. The holding portion 70 is equipped with a notch bellows portion 75 in which crest portions 75A and trough portions 75B which have a notch ring-shaped made by partially notching and opening an annulus ring are concentrically and alternately formed.SELECTED DRAWING: Figure 1

    【課題】蛇腹構造により円筒配管を保持する際に、円筒配管の蛇腹構造への取付工程を従来よりも短時間で行うことを可能とする。【解決手段】導風ダクト50は角筒形状であって、ラジエータ10と、ラジエータ10より前方に設けられたフロントグリル15との間に設けられ、ラジエータ10の前面12を取り囲むようにして車両前後方向に延設される。導風ダクト50の角筒形状の一部を構成する管壁には、円筒配管であるラジエータホース30を保持する保持部70が設けられる。保持部70は、円環が一部切り欠かれ開放された切欠リング状の山部75A及び谷部75Bが同心円状に交互に形成された切欠蛇腹部75を備える。【選択図】図1
