Abstract

A spoiler device for a vehicle includes a rear spoiler including an airflow controlling surface that is configured to continue to a roof surface and configured to be provided at a roof end, and an air duct including an air inlet opening to the airflow controlling surface and being formed penetrating through the rear spoiler, the air duct including an air outlet positioned in vicinity to an edge portion of the rear spoiler in a vehicle width direction, the air duct configured to guide an airflow at a vehicle top surface to a border portion between a vehicle rear side and a vehicle lateral side.

First claim

The invention claimed is:

1. A spoiler device for a vehicle, comprising:
a rear spoiler including an airflow controlling surface that is configured to extend from a roof surface of the vehicle and configured to be provided at an end of a roof of the vehicle; and
an air duct including an air inlet opening in the airflow controlling surface, the air duct passing through the rear spoiler, and including an air outlet positioned in an outer portion of the rear spoiler along a width direction of the vehicle, the air duct being configured to guide an airflow at a vehicle top surface to a border portion between a vehicle rear side and a vehicle lateral side;
wherein a vehicle top surface of the rear spoiler is flush with the roof surface of the vehicle.

2. The spoiler device for the vehicle according to claim 1 , wherein the air outlet is provided at an outer edge of the rear spoiler along the width direction of the vehicle and includes an opening having a configuration in which a dimension of the opening close to a rear of the vehicle is larger than a dimension of the opening further away from the rear of the vehicle.

3. The spoiler device for the vehicle according to claim 1 , wherein the air duct includes a fluid path having a configuration such that when viewing the vehicle top surface of the rear spoiler, a lower portion of the rear spoiler cannot be seen.

4. The spoiler device for the vehicle according to claim 1 , wherein a portion of the rear spoiler positioned at a rear of the air inlet defines only an airflow controlling surface.

5. The spoiler device for the vehicle according to claim 1 , wherein the air duct comprises a first air duct and a second air duct disposed only at respective opposite end portions of the rear spoiler along the width direction of the vehicle.

6. The spoiler device for the vehicle according to claim 1 , wherein the air inlet is sloped such that the air inlet declines from a front side of the vehicle to a rear side of the vehicle, and the air duct extends from an inner side to an outer side along the width direction of the vehicle.
