PROBLEM TO BE SOLVED: To stabilize traveling air flowing under the floor of a vehicle.SOLUTION: In a vehicle to which a vehicle front part structure is applied, a streamline part 28 of a vertical wall 26 of an air deflector 20 is disposed with a gradient to the vehicle rear side as it goes toward the inside in the vehicle width direction as viewed from the lower side of the vehicle. Thus, the traveling air striking on the vertical wall 26 is routed to the vehicle rear side of the streamline part 28 to stride over the end of the inside in the vehicle width direction of the vertical wall 26 (see an arrow D shown in Fig. 1). The lower end part of the streamline part 28 is inclined to the rear side of the vehicle in a side view. Thus, the traveling air striking on the vertical wall 26 is routed to the rear side of the vehicle of the streamline part 28 to stride over the lower end part of the streamline part 28 (see an arrow E shown in Fig. 1). Whereupon, at the rear side of the vehicle, a vortex, the axial direction of which is the longitudinal direction of the vehicle, is generated at the rear side of the vehicle of the streamline part 28. Therefore, the air under the floor of the vehicle is streamlined to the rear side of the vehicle by the aerodynamic force of the vortex, so that the flow of the air under the floor of the vehicle can be stabilized. |
