PROBLEM TO BE SOLVED: To provide an aerodynamic noise suppressing structure of a railway vehicle which can have reduction effect on a railway vehicle aerodynamic sound by means of decreasing air flow velocity in a truck storing space of the vehicle.SOLUTION: About an aerodynamic noise suppressing structure of a railway vehicle which reduces an aerodynamic sound generated in a truck storing space formed in the bottom of the vehicle to store a truck, a cavity part is formed in a position of the bottom of the vehicle, the position being apart from the truck storing space, upstream from the truck storing space along the direction of travel and at a prescribed depth.SELECTED DRAWING: Figure 1 【課題】台車格納用空間における流速自体を低減することで鉄道車両空力音の低減効果を発揮することができる鉄道車両空力音の低減構造を提供する。【解決手段】台車を格納するために車両の底部に形成された台車格納用空間において発生する空力音を低減する鉄道車両空力音の低減構造において、前記車両の底部には、前記台車格納用空間に対して進行方向に沿って上流側に離間した位置に所定の深さに形成されたキャビティ部が形成される。【選択図】図１
