The present invention provides an undercover structure capable of attaining the running stability/handling stability/comfort of the vehicle at a high level. In the undercover structure according to the present invention, a first cover part (15a) that is a lowermost part of an undercover (15) has a first rear end (15a2) positioned ahead of a front wheel axle (21). Further, a curved part (27) with a predetermined curvature is formed at the first rear end (15a2) of the first cover part (15a) in a side view. This generates a strong negative pressure in a region ahead of the front wheel axle (21). Accordingly, the flow rate of air flowing to each wheelhouse (23) decreases (the flow rate of the airflow between a road and a vehicle generated along the bottom surface of the first cover part (15a) of the undercover (15) increases). This causes an attraction force that attracts the vehicle (11) to a road surface to act on a vehicle body (13) of the vehicle (11), thereby making traveling stability more excellent.
本发明提供能够以高水准获得车辆的行驶稳定性/操纵稳定性/舒适性的底罩构造。在本发明的底罩构造中,使在底罩(15)中的作为位于最下方的部分的第1罩部(15a)的第1后端部(15a2)与前轮车轴(21)相比位于前方侧。另外,在第1罩部(15a)的第1后端部(15a2)形成在侧面观察时呈规定的曲率的曲率部(27)。由此,在与前轮车轴(21)相比的前方侧的区域中形成强负压区域。从而空气向车轮罩(23)的流量减少(在底罩(15)中的第1罩部(15a)的底面产生的路车间空气流的流量增加)。其结果,由于在车辆(11)的车身(13)作用有将车辆(11)向路面吸附的吸引力,因此能够获得更合适的行驶稳定性。
