PROBLEM TO BE SOLVED: To provide a flow straightening structure for a vehicle lower part in which travelling wind under floor is converged to a recess part in front of a rear wheel house where inflow of the travelling wind under floor is not desirable, the travelling wind under floor is strengthened by the convergence so as to be effectively separated into vehicle lower, so that the travelling wind under floor can be suppressed from flowing in the rear wheel house.SOLUTION: A flow straightening structure for a vehicle lower part includes a recess part 62 in front of a rear wheel house 61 on a lower side of the vehicle body. The recess part 62 includes a front wall 64 and a rear wall 66. The rear wall 66 is extended to the outside back in the vehicle width direction and extended to a lower part of the vehicle.SELECTED DRAWING: Figure 3

    【課題】本来、床下走行風を流入させたくないリヤホイールハウス前方の凹部に敢えて床下走行風を集束させ、集束させることで床下走行風の動きを強めて、効果的に車両下方へ剥離し、床下走行風がリヤホイールハウス内に流入するのを抑制することができる自動車の下部整流構造の提供を目的とする。【解決手段】車体下面のリヤホイールハウス61前方に凹部62が設けられた自動車の下部整流構造であって、上記凹部62は前壁64と後壁66とを備え、上記後壁66が車幅方向外側後方に延びると共に、車両下方に延設されたことを特徴とする。【選択図】図3
