Abstract
In an undercover structure according to the present invention, a first cover part that is a lowermost part of an undercover has a first rear end positioned ahead of a front wheel axle. This generates a strong negative pressure in a region ahead of the front wheel axle. Accordingly, a flow rate of air flowing to a wheelhouse decreases (a flow rate of airflow between a road and a vehicle generated along a bottom surface of the first cover part of the undercover increases). This causes an attraction force that attracts the vehicle to a road surface to act on a vehicle body of the vehicle, thereby making traveling stability more excellent.
