PROBLEM TO BE SOLVED: To provide a flow straightening structure for a lower part of a vehicle, capable of securing a minimum ground clearance in the middle of a vehicle width direction, as well as facilitating convergence of winds blowing under a floor toward the middle of the vehicle width direction to suppress generation of a turbulent flow, while preventing an interference between an undercover and a rear suspension.SOLUTION: In a flow straightening structure for a lower part of a vehicle, an undercover 46 comprises: a middle part 46C for covering a middle of a vehicle width direction; an inclined side part 46S for inclined downward and extending outward in the vehicle width direction from the middle part 46C in a front cross-sectional view for covering, from below, a front part of a trailing arm 29 of a rear suspension device 28; and a middle rear extension part extending to a rear side of the vehicle with respect to the inclined side part 46S in the middle of the vehicle width direction.SELECTED DRAWING: Figure 5
【課題】アンダカバーがリヤサスペンションと干渉することを防ぎながら、車幅方向中央の最低地上高を確保し、かつ床下風の車幅方向中央側への集束を促進して乱れを抑制する自動車の下部整流構造を提供する。【解決手段】アンダカバー46は、車幅方向中央を下方から覆う中央部46Cと、正面断面視で該中央部46Cから下方に傾斜して車幅方向外側へ延びてリヤサスペンション装置28のトレーリングアーム29前部を下方から覆う傾斜側部46Sと、車幅方向中央において傾斜側部46Sに対して車両後方に延びる中央後方延長部とを備えたことを特徴とする。【選択図】図5
