<P>PROBLEM TO BE SOLVED: To provide an underfloor structure of a vehicle that efficiently improves aerodynamic performance and cooling performance in a floor tunnel by suppressing a vortex generated at the front part of the floor tunnel. <P>SOLUTION: The underfloor structure of the vehicle includes a floor tunnel 6a extended in a vehicle longitudinal direction along an exhaust system 11 extending in the center part in a vehicle width direction along the vehicle longitudinal direction, at the rear of an engine room 2. A guide member 20 for suppressing interference between air flowing to the outside of the floor tunnel 6a through the front part of the floor tunnel 6a from the inside of the engine room 2 and running wind from front of the vehicle, is provided at the front of the floor tunnel 6a. <P>COPYRIGHT: (C)2012,JPO&INPIT |
