To provide a flow straightener that suppresses a vortex flow around a vehicle body.SOLUTION: A flow straightener is provided in a vehicle 1 that has a first surface part 33 arranged almost along a longitudinal direction, and a second surface part 32 connected to a vehicle-rear-side end of the first surface part via a ridge line becoming convex toward the outside of the vehicle. The flow straightener comprises a plurality of air flow generating parts PA that are arranged along the longitudinal direction of the ridge line on or near the ridge line and that generate an air flow traveling to the rear side of the vehicle, and a control part 200 that sequentially drives and stops the plurality of air flow generating parts along an arrangement direction.SELECTED DRAWING: Figure 2

    【課題】車体の周囲における渦流を抑制した整流装置を提供する。【解決手段】前後方向にほぼ沿って配置された第1の面部33と、車両外側に向け凸となる稜線を介して第1の面部の車両後方側の端部に接続された第2の面部32とを有する車両1に設けられる整流装置を、稜線又はその近傍に稜線の長手方向に沿って複数配列され、車両後方側へ進行する気流を発生する気流発生部PAと、複数の気流発生部を配列方向に沿って順次駆動及び停止する制御部200とを備える構成とする。【選択図】図2
