To provide an attachment structure of a vehicle drain pipe which can prevent air-column resonance caused by turbulence of airflow occurring at a tip of a drain pipe when a vehicle travels or a similar situation.SOLUTION: An attachment structure of a vehicle drain pipe includes: a drain pipe which drains condensed water generated in a vehicle to the outside of the vehicle; and a through hole which is provided on a floor panel of the vehicle and into which a tip of the drain pipe is inserted so as to protrude to the vehicle lower side of the floor panel. The drain pipe is attached to the through hole in a state that the tip protrudes inclining to the vehicle rear side in a direction from the floor panel toward the vehicle lower side.SELECTED DRAWING: Figure 3

    【課題】車両の走行時等に排水管の先端で発生する気流の乱れを起振源とする気柱共鳴を防止できる車両の排水管の取付構造を提供する。【解決手段】車両の排水管の取付構造は、車両で発生した凝縮水を車外へ排出する排水管と、前記車両のフロアパネルに設けられ、前記排水管の先端部が前記フロアパネルの車両下方に突出するように挿入される貫通孔と、を備え、前記排水管は、前記先端部が前記フロアパネルから車両下方に向かうにつれ車両後方に傾斜して突き出た状態で前記貫通孔に取り付けられる。【選択図】 図3
