PROBLEM TO BE SOLVED: To provide a rear spoiler device for a vehicle, capable of suppressing increase of pneumatic resistance, and reducing negative pressure on the vehicle rear surface.SOLUTION: The rear spoiler device 1 which is installed on the rear side of a roof 4 in the vehicle 3, has an inner wall 13 forming an air passage 10 between a rear window glass 5 and the inner wall in the vehicle 3, passes a part of an airflow AF1 moving rearward along the upper surface 4b of the roof 4 during running through the air passage 10 to make it an airflow AF2 heading toward the rear window glass 5. The inner wall 13 is configured to gradually widen the air passage 10 so that a distance L2 of a flow outlet 15 at the rear window glass 5 side in the air passage 10 is greater than a distance L1 of a flow inlet port 14 at the roof 4 side. |
