<p>Disclosed is a vehicle underfloor structure equipped with under covers (3, 4, 5, 6, 7) which cover underfloor portions of a vehicle, and drain members (D) which are provided in said under covers. The under covers are each equipped with a front side inclined wall (21) which tilts upward toward the vehicle rearward direction from a front side wall end section (26) that extends in the vehicle width direction of each under cover, and through at least a portion of which a drain port (33, 34, 42, 43, 44, 72, or 74) is provided; and a rear side inclined wall (22) which tilts downward toward a rear side wall end section (28) that extends in the vehicle width direction of each under cover from a wall bent section (27) connected to the front side inclined wall, and which has, on the surface of said wall, a travel wind flow rectifying surface (25) that rectifies travel wind flow. Furthermore, with regard to the shape of a dent formed in each under cover in the vehicle longitudinal direction, a first interior angle (?1) formed by the front side inclined wall is larger than a second interior angle (?2) formed by the rear side inclined wall, resulting in the length of the front side inclined wall being made different from the length of the rear side inclined.</p> |
