The bottom cover includes an air inlet into which air that has flowed from a front side toward a rear side in the vehicle front-rear direction is taken such that the air flows outward in a vehicle-width direction. The bottom cover further includes an air outlet provided at a position outward of the air inlet in the vehicle-width direction. The air outlet is an air outlet from which the air flows from the air inlet outward in the vehicle-width direction is discharged outward in the vehicle-width direction and downward in a vehicle-height direction. ## Claims ### Claim 1 A vehicle rear structure comprising a bottom cover disposed rearward of a rear wheel well in a vehicle front-rear direction, the bottom cover including an air inlet into which air that has flowed from a front side toward a rear side in the vehicle front-rear direction is taken such that the air flows outward in a vehicle-width direction, and the bottom cover including an air outlet provided at a position outward of the air inlet in the vehicle-width direction, the air outlet being an air outlet from which the air flowing from the air inlet outward in the vehicle-width direction is discharged outward in the vehicle-width direction and downward in a vehicle-height direction. ### Claim 2 (depends on 1) The vehicle rear structure according to claim 1, further comprising a discharge-side guide wall provided at a side edge of the air outlet, the discharge-side guide wall being configured to guide the air such that the air flows outward in the vehicle-width direction and downward in the vehicle-height direction. ### Claim 3 (depends on 2) The vehicle rear structure according to claim 2, wherein the discharge-side guide wall includes an outer slant wall extending from an outer-side edge of the air outlet inward in the vehicle-width direction and upward in the vehicle-height direction, the outer-side edge being on an outer side of the air outlet in the vehicle-width direction, and the outer-side edge extending in the vehicle front-rear direction. ### Claim 4 (depends on 2) The vehicle rear structure according to claim 2, wherein the discharge-side guide wall includes a rear slant wall extending from a rear-side edge of the air outlet forward in the vehicle front-rear direction and upward in the vehicle-height direction, the rear-side edge being on a rear side of the air outlet in the vehicle front-rear direction, and the rear-side edge extending in the vehicle-width direction. ### Claim 5 (depends on 1) The vehicle rear structure according to claim 1, further comprising an intake-side guide wall provided at a side edge of the air inlet, the intake-side guide wall being configured to guide the air such that the air flows outward in the vehicle-width direction. ### Claim 6 (depends on 1) The vehicle rear structure according to claim 1, wherein the bottom cover is provided with a duct configured such that air taken into the air inlet is discharged from the air outlet.
