Abstract: An airflow deflector for a vehicle includes: an exterior surface and at least one airflow deflector area in a portion on a vehicle rear side of the exterior surface. The airflow deflector area includes a slanted side that is slanted in a manner to extend to a vehicle lower side as extending to the vehicle rear side and an airflow deflector surface that extends in a vehicle vertical direction from the slanted section toward the exterior surface. An extending direction of a side of the airflow deflector surface, which serves as a boundary between the airflow deflector surface and a surface of the cover, is oriented inward or outward in a vehicle width direction with respect to a vehicle longitudinal direction. The airflow deflector surface is tilted inward or outward in the vehicle width direction with respect to the surface of the cover.
