PROBLEM TO BE SOLVED: To provide an aerodynamic device which can obtain a down force quantity, which is obtained by a conventional aerodynamic device, at a lower speed.SOLUTION: A lower surface part of each of a front wing and a rear wing, and a rear diffuser in an automobile is opened and provided with one or more taking-in ports which take in air current which flows from the front side to the rear side of the lower surface parts of the front wing and rear wing, and the rear diffuser during travelling of the automobile. An inner peripheral surface of a suction pipe in which a negative pressure is generated by an intake stroke of an engine as a driving force source of the automobile is opened and provided with one or more discharge holes which discharge air taken-in from each taking-in port, and each taking-in port and each discharge hole are communicated with each other by each communication passage.SELECTED DRAWING: Figure 1 |
