PROBLEM TO BE SOLVED: To provide a flow straightening structure for a lower part of a vehicle body, which can reduce air resistance by straightening an airflow generated on the downside of the vehicle body during vehicle traveling, and which can obtain proper aerodynamic characteristics.SOLUTION: In a flow straightening structure for a lower part of a vehicle body, a flap 2 protruding downward from the lower part of the vehicle body is provided ahead of a tire. A protrusion 4 protruding downward the lower part of the vehicle body ahead of the flap 2 is provided, and a flow straightening member 3 for splitting an airflow, which is directed backward from a front side through the downside of the vehicle body 10, in a vehicle-body width direction by the protrusion 4 is provided.
【課題】車両走行中に車体の下側に発生する気流を整えて、空気抵抗を低減することができ、良好な空力特性を得ることができる車体下部整流構造を提供する。【解決手段】タイヤの前方に車体の下部から下方へ突き出すフラップ2を備える車体下部整流構造において、フラップ2の前方の車体下部から下方へ突き出す凸部4を有し、凸部4で車体10の下側を通って前方から後方に向かう気流を車体幅方向へ分流させる整流部材3を設ける。【選択図】図2
