To provide a flow straightening device which appropriately straightens a separation flow caused by a collision of travel wind with a wheel.SOLUTION: A flow straightening device is provided in a vehicle 1 including a wheel FW, and a space part S opening downward and outward a vehicle body and accommodating a part of the wheel. The flow straightening device includes an air flow ejection part 71, 100 (100o, 100i) which is provided in the space part in a front side of the vehicle with respect to the wheel, and ejects an air flow forming a turbulent boundary layer T adjacent to an inner face part of the wheel in a vehicle width direction.SELECTED DRAWING: Figure 2
