PROBLEM TO BE SOLVED: To make an air flow discharged from a guide part smoothly merge with air flowing in an underfloor space of a vehicle.SOLUTION: In a vehicle 10 to which a foil house rear part structure S1 is applied, a curved part 44 of an upper wall 40 of a guide part 30 swells obliquely forward below the vehicle in side view to be connected to a discharge part 34. An air flow F1 in a flow passage 36 moves along an upper wall 40 through Coanda effect, so in an air flow F1 along the curved part 44, a flow component moving to a vehicle rear side increases. Consequently, an air flow F1 discharged from the discharge part 34 is substantially in the same direction with an air flow F2 in an underfloor space of the vehicle 10. Consequently, the air flow F1 can be made to smoothly merge with the air flow F2 while a decrease in flow rate of the air flow F1 discharged from the discharge pa rt 34 is suppressed. |
