To inhibit a separation vortex from being accumulated around a front pillar lower part to reduce occurrence of aerodynamic noise (wind noise) when a vehicle travels.SOLUTION: An aerodynamic noise reduction member 10 is provided around at least a lower part of a front pillar 4 of a vehicle 1, extends along an inner side of the front pillar when viewed in a vehicle width direction, and is formed so that a curve of an upper surface changes from a recessed shape to a protruding shape from the lower side to the upper side on a cross section as seen in the vehicle width direction at the lower part of the front pillar. A step is not formed in a joint line with the front pillar.SELECTED DRAWING: Figure 2
【課題】車両走行時において、フロントピラー下部周辺における剥離渦の滞留を抑制し、空力騒音(風切り音)の発生を低減すること。【解決手段】少なくとも車両1のフロントピラー4下部周辺に設けられる空力騒音低減部材10であって、前記フロントピラーの車幅方向内側に沿って延設されると共に、前記フロントピラーの下部における車幅方向断面において、上面の曲線が下方から上方に向けて凹から凸に変化するように形成され、且つ前記フロントピラーとの繋ぎ目において段差が形成されていない。【選択図】図2
