To provide a flow straightening device which appropriately straightens an air flow between a vehicle body bottom surface and a road surface, when a road clearance is changed.SOLUTION: A flow straightening device is provided in a vehicle 1 having a vehicle body, a wheel FW attached to the vehicle body with a part thereof protruding downward from the vehicle body, and a suspension supporting the wheel such that the wheel can vertically reciprocate with respect to the vehicle body. The flow straightening device includes a road clearance detection part 210 which detects a road clearance which is a vertical distance from a bottom face of the vehicle body to a road surface, an air flow generating part 100 which is provided in a bottom part of the vehicle body and generates an air flow, and a control part 200 which generates a downward air flow Fd having a downward velocity component in the air flow generating part when the road clearance transitions increase, and generates a rearward air flow Fb having a rearward velocity component in the air flow generating part when the road clearance transitions decrease.SELECTED DRAWING: Figure 1

    【課題】車体下面と路面との間の気流を地上高が変動した場合に適切に整流する整流装置を提供する。【解決手段】車体と、車体から一部が下方に突出して取り付けられた車輪FWと、車輪を車体に対して上下方向にストローク可能に支持するサスペンションとを有する車両1に設けられる整流装置を、車体の下面の路面からの上下方向距離である地上高を検出する地上高検出部210と、車体の下部に設けられ気流を発生する気流発生部100と、地上高が増加方向に推移した場合に、気流発生部に下方への速度成分を有する下向気流Fdを発生させるとともに、地上高が減少方向に推移した場合に、気流発生部に後方への速度成分を有する後向気流Fbを発生させる制御部200とを備える構成とする。【選択図】図1
