  • Patent number: 11124249
    Abstract: 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.

  • Patent number: 11077893
    Abstract: 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.

  • Patent number: 10960933
    Abstract: A torsion beam type of rear suspension comprising a pair of right-and-left trailing arms and a torsion beam. A floor under cover for airflow straightening is attached to a portion of a vehicle body in front of the rear suspension so as to cover a vehicle-body lower face. A cover-support bracket is laid between a rear portion of a side sill and an inward side, in a vehicle width direction, of an arm pivot of the trail arm. A portion of the floor under cover which is positioned in the vicinity of its rear end is engaged with the cover-support bracket such that a rear end portion of the floor under cover is extended from an inward-side edge of a front portion of a rear wheel house to an inside of the rear wheel house.

  • Patent number: 10906599
    Abstract: A garnish is provided with a protrusion portion which protrudes outwardly, in a vehicle width direction, so as to suppress a side-face airflow flowing below a door maximum-width portion of a side portion of a cabin from going around below a vehicle floor. A plate-shaped tire deflector is provided at a lower end portion of a front edge of a rear wheel house which corresponds to a position, in a vertical direction, of a rear end portion of the protrusion portion, wherein the tire deflector is configured to deflect a side-face airflow flowing above the protrusion portion such that the side-face airflow is turned toward an outward side, in the vehicle width direction, so as not to flow into the rear wheel house and adheres to a tire-wheel outer face.

  • Patent number: 10899388
    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.
