PROBLEM TO BE SOLVED: To provide a flow straightening structure of a vehicle in which a proper streamlining property, when a recess part is arranged at a corner part ridge line extending in a fore-and-aft direction of the vehicle, between a traveling wind flowing along one side face and a traveling wind flowing along the other face, is secured so as to suppress increment of aerodynamic drag.SOLUTION: A flow straightening structure of a vehicle is given in which: corner part ridge lines L1, L2 extending in a fore-and-aft direction of the vehicle are formed between one faces 56, 59 and the other faces 55, 58 extending in the fore-and-aft direction of the vehicle; recess parts 57, 60 are arranged in the corner part ridge lines L1, L2; separation parts 93, 96, 97, 98 of traveling wind are arranged on the upstream side of the one faces 56, 59 and the other faces 55, 58 of the recess parts 57, 60 sandwiching the corner part ridge lines L1, L2; reattachment promotion parts 56a, 59a of the traveling wind are formed on the downstream side of the recess parts 57, 60 of the one faces 56, 59 where the strength of the wind is relatively strong; and flat parts 55a, 58a are formed on the downstream side of the recess parts 57, 60 of the other faces 55, 58 where the strength of the wind is relatively weak.SELECTED DRAWING: Figure 12

    【課題】車両の前後方向に延びる角部稜線に凹部が設けられたものにおいて、一方の面に沿って流れる走行風と、他方の面に沿って流れる走行風との両方の走行風に対して適切な整流性を確保し、空力抵抗の増加を抑制する自動車の整流構造を提供する。【解決手段】車両の前後方向に延びる一方の面56,59と他方の面55,58との間に、車両の前後方向に延びる角部稜線L1,L2が形成され、角部稜線L1,L2に凹部57,60が設けられ、凹部57,60の角部稜線L1,L2を挟んだ一方の面56,59と他方の面55,58の上流側に走行風の剥離部93,96,97,98が設けられ、風の勢いが相対的に強い一方の面56,59の凹部57,60下流側に走行風の再付着促進部56a,59aが形成され、風の勢いが相対的に弱い他方の面55,58の凹部57,60下流側に平坦部55a,58aが形成されたことを特徴とする。【選択図】図12
