Abstract

A fender liner structure is disposed in a wheel house of a front wheel of a vehicle. The vehicle includes a sub radiator disposed on a vehicle front side of a fender liner. The fender liner structure includes a liner body portion curving in an arch shape to cover the front wheel from above and a lower wall portion extending to the front of the vehicle from a lower end of the liner body portion on the vehicle front side. The liner body portion includes a first vent hole penetrating a vehicle front side part of the liner body portion. The lower wall portion includes a second vent hole penetrating a vehicle rear side end portion of the lower wall portion in an upper-lower direction. The lower wall portion includes a negative pressure generation part configured to generate a negative pressure under the second vent hole.

First claim

What is claimed is:

1 . A fender liner structure disposed in a wheel house of a front wheel of a vehicle including a sub radiator disposed in front of a fender liner, the fender liner structure comprising:
a liner body portion curving in an arch shape to cover the front wheel from above, the liner body portion including a first vent hole penetrating a vehicle front side part of the liner body portion in a front-rear direction; and a lower wall portion extending to the front of the vehicle from a lower end of the liner body portion on the vehicle front side, the lower wall portion including a second vent hole penetrating a vehicle rear side end portion of the lower wall portion in an upper-lower direction and the lower wall portion including a negative pressure generation part configured to generate a negative pressure under the second vent hole.

2 . The fender liner structure according to claim 1 , wherein the first vent hole is formed in a lower end portion of the vehicle front side part of the liner body portion such that an upper end of the first vent hole is positioned lower than a center of the front wheel.

3 . The fender liner structure according to claim 1 , wherein:
the vehicle is provided with an air intake port taking in cooling air for the sub radiator in front of the sub radiator; and a size of the air intake port is relatively smaller than in a case where the second vent hole is not formed.

4 . The fender liner structure according to claim 1 , wherein the liner body portion includes a third vent hole extending in the upper-lower direction through the liner body portion in an end portion of the vehicle front side part of the liner body portion on a vehicle width direction outer side of the vehicle.

5 . The fender liner structure according to claim 1 , wherein the negative pressure generation part includes air spats attached to a vehicle front side of the second vent hole beneath a lower surface of the lower wall portion and having a wind receiving plate extending downwards.

6 . The fender liner structure according to claim 1 , wherein the negative pressure generation part includes an inclined member attached to a vehicle front side of the second vent hole beneath a lower surface of the lower wall portion and having an inclined surface inclined downwards from the lower surface of the lower wall portion toward a vehicle rear side.

7 . The fender liner structure according to claim 1 , wherein:
the second vent hole includes a plurality of fins guiding air and inclined downwards toward a vehicle rear side; and a part where the fin extends downwards beyond a lower surface of the lower wall portion constitutes the negative pressure generation part.

8 . The fender liner structure according to claim 1 , wherein:
the lower wall portion includes a vertical wall portion extending downwards from a vehicle front side of the second vent hole and an inclined wall portion inclined downwards from a tip portion of the lower wall portion toward a vehicle rear side and connected to a lower end of the vertical wall portion; and the vertical wall portion and the inclined wall portion constitute the negative pressure generation part.

9 . The fender liner structure according to claim 1 , further comprising a duct disposed behind the sub radiator and guiding air to the first vent hole and the second vent hole after passage of the air through the sub radiator.
