PROBLEM TO BE SOLVED: To provide an underfloor structure of an automobile, that can suppress increase of an aerodynamic drag while minimizing vertical walls and separation parts, which extend in the vehicle longitudinal direction for straightening a flow, and improve the layout property by increasing the space of auxiliary equipment or the frame structure.SOLUTION: In an underfloor flow straightening part 70, on the front of an almost flat floor 73 extending in the vehicle longitudinal direction, a first vertical wall 75 is provided, which prevents an underfloor traveling wind from outflowing outward in the vehicle width direction and extends in the vehicle longitudinal direction, and a first separation part 77 is provided, which is separated backward of the vehicle from the first vertical wall 75 and is positioned outward in the vehicle width direction.SELECTED DRAWING: Figure 3

    【課題】整流用の車両前後方向に延びる縦壁や剥離部を最小化しつつ、空力抵抗の増加を抑制することと、補機またはフレーム構造のスペース増加を図って、そのレイアウト性向上を図ることができる自動車の床下構造の提供を目的とする。【解決手段】床下整流部70は、車両前後方向に延びる略平坦な床面73の前部に、床下走行風の車幅方向外側への流出を防ぎ車両前後方向に延びる第1縦壁75が設けられると共に、該第1縦壁75に対して車両後方に離間し、かつ車幅方向外側に位置する第1剥離部77が設けられたことを特徴とする。【選択図】図3
