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.

Vehicle wheel

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.

Vehicle front structure

A front deflector configured to be provided on a surface ahead of a front wheel of a vehicle. The front deflector includes a first opening forward of the vehicle, the first opening configured to receive air into an inner space of the front deflector when the vehicle travels forward; a guide wall that directs the air received into the inner space from the first opening to at least a vehicle-width-direction outer side in the inner space; and a second opening that opens rearward of the first opening in a position that overlaps with a front wheel of the vehicle, and exhausts the air in the inner space to the vehicle-width-direction outer side.

Front deflector

A deflector structure of an automotive vehicle comprises a deflector. The deflector comprises a traveling-wind control part to control a flow of a traveling wind generated in forward traveling of an automotive vehicle. The traveling-wind control part comprises an outside control section and an inside control section. The outside control section and the inside control section are shaped such that an atmospheric pressure of an outside space portion which is positioned just in front of an outside part, in the vehicle width direction, of a front wheel is lower than that of a central space portion which is positioned just in front of a central part, in the vehicle width direction, of the front wheel at a level position from a lower end of the deflator to a vicinity below the lower end of the deflector.

Deflector structure of automotive vehicle

A deflector structure for an automobile. The deflector structure includes a protruding structure having an outer surface positioned to be hit by traveling air when the automobile travels forward. The outer surface of the protruding portion includes a first inclined portion located on a vehicle-width-direction outer side and inclined upward toward the automobile front side; and a second inclined portion located on a vehicle-width-direction inner side and inclined upward toward the automobile front side. An angle of inclination of the second inclined portion on an acute angle side of the second inclined portion with respect to a horizontal direction is smaller than an angle of inclination of the first inclined portion on an acute angle side of the first inclined portion with respect to the horizontal direction.

Deflector structure for automobile

An airflow straightening structure of an automotive vehicle, in which slits for traveling-air peeling off (separation) and connection portions for cover reinforcing are adjacently provided at a rear-end edge portion of a cover having a substantially-flat airflow straightening face extending in a vehicle longitudinal direction, wherein protrusions are provided to extend in a direction crossing the vehicle longitudinal direction along a cover surface of the cover which are positioned in front of the connection portions.
