Deflector structure for automobile
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.

the curved edge portion is mounted at a plurality of positions to a lower surface of a corner portion of the bumper.
8. The deflector structure of claim 1 , wherein
the lower member includes a first curved edge portion that is configured to be attached to the upper member by fasteners at a plurality of positions.
9. The deflector structure of claim 1 , wherein
the upper member includes a first vertical wall portion,
the lower member includes a second vertical wall portion, and
the first vertical wall is configured to be attached to the second vertical wall by fasteners at a plurality of positions.
10. The deflector structure of claim 9 , wherein
the second vertical wall portion is integrally formed with the outer surface of the protruding portion.
11. The deflector structure of claim 1 , wherein
a distance between a lower edge of the protruding portion and the ground when the deflector structure is mounted to the vehicle is approximately 110 mm.
12. A deflector structure for an automobile, the deflector structure comprising:
a deflector mounted on a lower surface ahead of a front wheel well in the automobile,
a protruding portion protruding downward and having an outer surface provided on a lower surface of the deflector, the outer surface positioned to be hit by traveling air when the automobile travels forward, wherein
the outer surface of the protruding portion comprises
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, wherein
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, and
the second inclined portion includes an upper-side inclined portion having a first angle of inclination and a lower-side inclined portion including a second angle of inclination.
13. The deflector structure of claim 12 , wherein
the first angle of inclination is different from the second angle of inclination.
14. The deflector stricture of claim 12 , wherein
the first angle of inclination of the upper-side inclined portion on the acute angle side thereof with respect to the horizontal direction is smaller than the second angle of inclination of the lower-side inclined portion on the acute angle side thereof with respect to the horizontal direction.
15. The deflector structure of claim 12 , wherein
the first and second angles of inclination on the acute angle side thereof with respect to the horizontal direction are smaller than an angle of inclination of the first inclined portion on the acute angle side thereof with respect to the horizontal direction.
16. A deflector structure for an automobile, the deflector structure comprising:
a protruding structure having an outer surface positioned to be hit by traveling air when the automobile travels forward, wherein
the outer surface comprising
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, wherein
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,
the second inclined portion includes an upper-side inclined portion having a first angle of inclination and a lower-side inclined portion including a second angle of inclination, and
the first angle of inclination of the upper-side inclined portion on the acute angle side thereof with respect to the horizontal direction is smaller than the second angle of inclination, of the lower-side inclined portion on the acute angle side thereof with respect to the horizontal direction.
