The purpose of the present invention is to provide a lower vehicle-body structure for a vehicle, which is capable of improving aesthetics by suppressing a muffler from being seen from the rear of the vehicle, and improving aerodynamic characteristics by suppressing traveling wind under the floor from entering the rear of a rear bumper. Wherein a shield member (60) is provided between the rear bumper (4) and the muffler (10), the shield member (60) overlaps at least a rear vertical wall (10b) of the muffler (10) in the vertical direction in a vehicle rear view angle and extends in the vehicle width direction, and the shield member (60) is provided with a guide portion (62). The guide portion (62) guides downward the underfloor traveling wind flowing rearward from the lower portion of the muffler (10).
本发明目的在于提供一种车辆的下部车身结构,其能够抑制从车辆后方看到消声器,提高美观度,并且抑制地板下的行驶风卷入后保险杠后方,从而改善空气动力特性。其中,在后保险杠(4)和消声器(10)之间设置遮蔽构件(60),该遮蔽构件(60)在车辆后方视角下与上述消声器(10)的至少后部纵壁(10b)在上下方向重合且向车宽方向延伸,在该遮蔽构件(60)设置有向导部(62),向导部(62)向下引导在上述消声器(10)的下部向后方流动的地板下的行驶风。
