Abstract: A fender liner includes a fender liner body provided in an arch of a fender included in a wheel house of a vehicle. The fender liner body includes a recess that is provided from an upper portion of the fender liner body in a vehicle height direction to a rear portion of the fender liner body in a vehicle front-rear direction and is greatly recessed rearward in the vehicle front-rear direction more in the rear portion than in the upper portion.

Abstract: A vehicle understructure includes a flow adjusting member provided rearward of a protruding member protruding further toward a vehicle lower side than a lower surface of a rocker panel, a front bumper, or a rear bumper as viewed from a vehicle width direction, the flow adjusting member being configured to adjust an air flow that flows from a vehicle front side toward a vehicle rear side along the protruding member during traveling of a vehicle. The flow adjusting member has a main part and a guide part provided at a lower part of an end part of the flow adjusting member, the guide part being inclined with respect to the main part toward the vehicle rear side such that a distance between the guide part and a rear end of the vehicle reduces toward an end part of the guide part in the vehicle width direction.

Abstract: A vehicle rear structure includes a bottom cover disposed rearward of a rear wheel well in a vehicle front-rear direction. 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.

Abstract: A mud guard portion is placed on a vehicle rear side relative to a rear tire. This makes it possible to restrain mud or the like splashed by the rear tire from hitting an underfloor. Further, an inside flow regulating portion is provided adjacently to an inner side of the mud guard portion in the vehicle width direction, and the inside flow regulating portion extends from its upper end toward a vehicle lower side and toward the vehicle rear side. Hereby, when a travel wind flowing on an inner side of the rear tire in the vehicle width direction in the wheel house hits the inside flow regulating portion, the travel wind flows toward the vehicle rear side along a deflection wall portion of the inside flow regulating portion. Accordingly, turbulence of the air on a vehicle rear side of the rear tire due to the travel wind is restrained.

Abstract: A vehicle front portion structure, first guides are formed in a lower inner wall portion that configures part of a wheel well, and are inclined outward in a vehicle width direction and in a vehicle rearward direction as seen in a plan view. Furthermore, first open portions that open toward the vehicle rearward direction are formed in rear end portions of the first guides.

Because of this, inside the wheel well the airflows flow in the vehicle rearward direction from the first open portions, so the airflows are restrained from being blown outward in the vehicle width direction from the wheel well resulting in the occurrence of air turbulence at due to the airflows rushing out from the wheel well is controlled.

Abstract: In a vehicle to which a wheel well rear portion structure has been applied, a curved portion of an upper wall of a guide portion bulges obliquely toward the vehicle lower side as seen in a side view and is connected to a discharge portion. An air flow flowing in a flow channel flows along the upper wall due to the Coanda effect, so in the air flow along the curved portion the flow component heading toward the vehicle rear side becomes larger. The flow direction of the air flow discharged from the discharge portion substantially coincides with the flow direction of an air flow flowing in the space under the body of the vehicle. In a state in which a drop in the flow speed of the air flow discharged from the discharge portion is controlled, the air flow can be caused to smoothly merge with the air flow.

Abstract: A vehicle front portion structure, first guides are formed in a lower inner wall portion that configures part of a wheel well, and are inclined outward in a vehicle width direction and in a vehicle rearward direction as seen in a plan view. Furthermore, first open portions that open toward the vehicle rearward direction are formed in rear end portions of the first guides. For this reason, airflows flow along vehicle width direction inner surfaces of the first guides such that the airflows are altered to flows in the vehicle rearward direction. Because of this, inside the wheel well the airflows flow in the vehicle rearward direction from the first open portions, so the airflows are restrained from being blown outward in the vehicle width direction from the wheel well resulting in the occurrence of air turbulence at due to the airflows rushing out from the wheel well is controlled.

Abstract: A first opening is formed in a vertical wall portion, and a second opening is formed in an underfloor. Airflow partially flows into the first opening and hits a rear face of an inclined wall portion, so as to be discharged from the second opening toward a vehicle rear side. The airflow that cannot enter the first opening flows toward the inclined wall portion along the vertical wall portion so that the airflow is drawn to the airflow flowing into the first opening. The airflow that cannot enter the first opening flows toward the vehicle rear side along the inclined wall portion. Detachment of the airflow from the inclined wall portion is restrained, and airflow flows toward the vehicle rear side along the underfloor of the vehicle. Air flowing from a side part of the vehicle into the rear wheel house restrains a decrease in steering stability.
