  In the present invention, the flap 18 is a member that protrudes at least downward and extends in the width direction, and is not limited to the above-described shape as long as the traveling wind can be rectified in the width direction. For example, the current plate 20 may have a shape having an inclined surface 18a similar to the flap 18, may be a semi-cylindrical member, or may be a triangular prism-shaped member.

  The first vertical wall 22 is formed on the rear side in the front-rear direction with respect to the flap 18 and on the inner side in the width direction with respect to the tire storage portion 14. In the present embodiment, the first vertical wall 22 is formed at an inner position in the width direction than the flap 18.

  FIG. 5 is a cross-sectional view showing a cross section in the width direction of the first vertical wall 22 and the second vertical wall 24 taken along the line V-V shown in FIG. As shown in FIG. 5, the first vertical wall 22 is a plate-like member that protrudes downward from the vehicle body and extends in the front-rear direction. Further, the first vertical wall 22 is formed such that the rear end portion in the front-rear direction thereof is positioned behind the rear end portion in the front-rear direction of the tire storage portion 14.

  The second vertical wall 24 is formed at a rear side position in the front-rear direction with respect to the rectifying plate 20 so as to face the first vertical wall 22. Moreover, in this embodiment, the 2nd vertical wall 24 is formed in the outer side position of the width direction of a vehicle body rather than the baffle plate.

  As shown in FIG. 5, the second vertical wall 24 is a plate-like member that protrudes downward from the vehicle body and extends in the front-rear direction. Further, the second vertical wall 24 is formed so that the rear end portion in the front-rear direction thereof is located behind the rear end portion in the front-rear direction of the tire storage portion 14.

  The first vertical wall 22 and the second vertical wall 24 face each other and are substantially parallel to each other, and form a flow path for airflow flowing from the front to the rear.

  Note that the first vertical wall 22 and the second vertical wall 24 protrude on the lower side of the vehicle body and are arranged to face each other, and the shape of the first vertical wall 22 and the second vertical wall 24 is particularly limited if an air flow path can be formed. Not. For example, the first vertical wall 22 and the second vertical wall 24 may be semi-cylindrical members or triangular prism-shaped members.

  The flap 18 and the first vertical wall 22 are connected by a first connecting portion 26. The first connection portion 26 is a plate-like member that protrudes downward from the vehicle body. Moreover, the 1st connection part 26 has a convex curved shape toward the inner side of the width direction, and has connected the flap 18 and the 1st vertical wall 22 smoothly.

  The rectifying plate 20 and the second vertical wall 24 are connected by a second connection portion 28. The second connection portion 28 is a plate-like member that protrudes downward from the vehicle body. The second connection portion 28 has a curved shape that protrudes outward in the width direction, and smoothly connects the rectifying plate 20 and the second vertical wall 24.

  The first connection part 26 and the second connection part 28 are arranged to face each other so that the distance in the width direction gradually decreases from the front to the rear. The first connecting portion 26 and the second connecting portion 28 arranged in this manner are airflow between the flap 18 and the first vertical wall 22 (between the current plate 20 and the second vertical wall 24) in the front-rear direction. The flow path is formed. The flow path formed by the first connection portion 26 and the second connection portion 28 gradually decreases in width from the front toward the rear.

It may be a separate member from the cover, or may be formed integrally with the under cover.

  In the vehicle body structure 16 configured as described above, the traveling wind rectified in the width direction by the flap 18 and the rectifying plate 20 flows into a space between the flap 18 and the rectifying plate 20 that are arranged apart from each other. The traveling wind that has flowed into this space flows from a wide space into a narrow space, and is thus accelerated toward the rear. In other words, the flap 18 and the rectifying plate 20 can generate an airflow directed backward between them and accelerate the airflow backward. Further, the flap 18 and the rectifying plate 20 can reduce the traveling wind flowing into the tire storage portion 14 by rectifying the traveling wind from the front and changing the airflow to the rear.

  Then, the accelerated airflow flows into the flow path formed by the first connection portion 26 and the second connection portion 28. The width of the channel gradually decreases from the front to the rear. Therefore, the airflow flowing into the flow path is further accelerated from the front to the rear. That is, the 1st connection part 26 and the 2nd connection part 28 can further accelerate the airflow which flows among them toward back.

  In this way, the traveling wind is rectified by the flap 18 and the rectifying plate 20 and becomes an airflow passing between the flap 18 and the rectifying plate 20. The airflow passes between the flap 18 and the current plate 20, and then passes through the flow path formed by the first connection portion 26 and the second connection portion 28, thereby being accelerated rearward. .

  Further, the accelerated airflow passes through the flow path formed by the first vertical wall 22 and the second vertical wall 24 while maintaining the flow. In other words, the first vertical wall 22 and the second vertical wall 24 can reliably flow the airflow flowing rearward along the tire storage portion 14 while maintaining the flow. .

  Further, the formed airflow flows backward while sucking ambient air. In particular, the air flows backward while sucking the air around the tire storage portion 14. More specifically, by sucking the air behind the flap 18 and around the outer position in the width direction of the first connection portion 26, a new air flow from the front position of the tire storage portion 14 toward the air flow path is obtained. Can form a simple airflow. Thereby, the traveling wind flowing into the tire storage portion 14 can be further reduced.

  Further, according to the vehicle body structure 16 of the present embodiment, since the amount of traveling wind flowing into the tire storage portion 14 can be reduced as described above, the generation of turbulence in the tire storage portion 14 is suppressed, Air resistance can be reduced and aerodynamic performance can be improved.

Furthermore, the fuel efficiency can be further improved by improving the aerodynamic performance.

  In the above embodiment, the first vertical wall 22 and the second vertical wall 24 are disposed so as to be substantially parallel to each other, but the present invention is not limited to this. For example, the separation distance between the first vertical wall and the second vertical wall may be gradually reduced toward the rear. That is, the flow path formed by the first vertical wall 22 and the second vertical wall 24 may be configured to gradually narrow toward the rear. Thereby, the airflow which flows through this flow path can be further accelerated as it goes back. Further, by further accelerating, the amount of traveling wind flowing into the tire storage portion 14 can be further reduced, aerodynamic performance can be improved, and fuel efficiency can be further improved.

  In the above embodiment, the rear end portions of both the first vertical wall 22 and the second vertical wall 24 are formed so as to be rearward of the rear end portion of the tire storage portion 14.
