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.

Abstract: A rim portion of a vehicle wheel has an outer flange portion. In a region of the outer flange portion, a space portion between spoke portions is disposed on a radial-direction inner side, a first inclined surface and a second inclined surface are provided. The first inclined surface is provided on an axial-direction outer side of an outer flange outer circumferential portion. The second inclined surface is on an axial-direction outer side of an outer flange inner circumferential portion. The first inclined surface is formed to incline from the axial-direction outer side toward an axial-direction inner side as the first inclined surface extends from a radial-direction outer side end toward the radial-direction inner side. The second inclined surface is a surface formed to incline from the axial-direction inner side toward the axial-direction outer side as the second inclined surface extends from the radial-direction outer side toward the radial-direction inner side.

Abstract: A vehicle front structure is provided for preventing a vortex from being generated between high-speed air separated from an outer edge of a deflector and low-speed air in a front wheel house due to a wind speed difference. Embodiments include a deflector disposed in front of a front wheel house projected downward from a lower surface of a bumper face. The deflector includes an air introducing section to introduce air into a space inside the deflector in a front portion of the deflector; and an intermediate-speed wind generating hole section that communicates with the air introducing section and generates an airflow at an intermediate wind speed, lower than a wind speed of air separated from deflector outer edges and higher than a wind speed of air in the front wheel house, in an area not opposing a tire in a vehicle front view of a portion immediately behind the deflector.

Abstract: A front vehicle-body structure flows air from the vehicle lower side to its upper side. After hitting a front bumper face, the air is separated and flows around and along a top face of an exterior member, ensuring aerodynamic performance. Embodiments include exterior members covering the upper side of an engine room, and a front grille disposed on a lower side relative to a front end portion of the exterior member. A rectification member extends the width of the exterior member in the vehicle width direction on the lower side of the exterior member front end portion. The rectification member includes a front piece portion extending toward the vehicle up-down-direction lower side from the exterior member to an upper end portion of the front grille, and a lower piece portion extending toward the vehicle rear side from an upper end of the front piece portion.

Abstract: An arm cover comprises a main part and a front part. These parts are configured such that when the rear suspension takes a standard vehicle-weight position, these parts are respectively inclined rearwardly and downwardly, wherein an angle of inclination of the inclined front part is smaller than that of the inclined main part. When the rear suspension takes the standard vehicle-weight position, a front edge of the front part is located at a higher level than a bottom face portion of a under cover, and when the rear suspension takes a rebound position, the front edge of the front part is located at a position which is higher than a level of the bottom face portion of the under cover and close to a rear end portion of the under cover.
