Vehicle rear spoiler device

摘要

Provided is a vehicle rear spoiler device to be mounted on a rear side of a roof of a vehicle. The vehicle rear spoiler device includes a wall surface for forming an air flow path between the wall surface and a rear window glass of the vehicle. A part of an air current moving rearward along a roof surface of the roof during traveling is caused to pass through the air flow path as a downward current toward the rear window glass. The wall surface is formed to gradually widen the air flow path in a manner that an outflow width of an outlet on the rear window glass side in the air flow path is larger than an inflow width of an inlet on the roof side in the air flow path.

主权项

1. A vehicle rear spoiler device, comprising:
a wall surface for forming an air flow path, through which a part of an air current moving rearward along a roof surface of a vehicle passes as a downward current, the air flow path being formed between the wall surface and a rear part of the vehicle; an outlet side edge portion formed on the wall surface correspondingly to an outlet of the air flow path; and an inlet side edge portion formed on the wall surface correspondingly to an inlet of the air flow path, wherein an outflow width corresponding to a distance between the wall surface and the rear part of the vehicle at the outlet side edge portion is set to be larger than an inflow width corresponding to a distance between the wall surface and the rear part of the vehicle at the inlet side edge portion, and wherein a guide portion is formed on the wall surface, the guide portion having a groove or a linear protrusion diverging from a central portion toward an outside in the vehicle width direction, inclining to a lower side along a direction toward the outside in the vehicle width direction, and one end portion of the guide portion extends toward a vehicle rear edge of the wall surface.
