PROBLEM TO BE SOLVED: To realize obtaining a large drag as the whole vehicle, by appropriately arranging a plurality of aerodynamic brake plates when the aerodynamic brake plate emerges.SOLUTION: By installing aerodynamic brake plates 20 so as not to be adjacent to each other in a vehicle width direction 110, a part of a flow that strikes the aerodynamic brake plates 20 to be separated, flows to the inside of the row of the aerodynamic brake plates 20, and strikes the aerodynamic brake plates 20 behind the adjacent row in the vehicle longitudinal direction 100. Therefore, since a speed of wind flowing inside the row of the aerodynamic brake plates 20 increases, the drag force inside the row of the aerodynamic brake plates 20 increases, and the drag generated in the entire vehicle increases.SELECTED DRAWING: Figure 3
【課題】複数の空力ブレーキ板を適切に配置にすることにより、空力ブレーキ板の出現時に車両全体として大きな抗力が得られることを実現する。【解決手段】空力ブレーキ板20を車両幅方向110に隣り合わないように設置することで、空力ブレーキ板20に当たって剥離した流れの一部が空力ブレーキ板20の列の内側へ流れ、車両前後方向100で隣の列の後方の空力ブレーキ板20に当たる。これにより、空力ブレーキ板20の列の内側に流れる風速が増加するため、空力ブレーキ板20の列の内側での抗力が増加し、車両全体で発生する抗力が増加する。【選択図】図3
