To provide a new pressure fluctuation reduction structure which enables reduction of at least pressure fluctuation in a low frequency range of pressure fluctuation occurring in a storage space provided at a bottom part of a vehicle body of a railway vehicle to store a truck.SOLUTION: A pressure fluctuation reduction structure reduces at least pressure fluctuation in a low frequency range of pressure fluctuation occurring in a storage space S provided at a bottom part of a vehicle body 20 of a railway vehicle 1 to store a truck 10. The pressure fluctuation reduction structure includes protruding members 30 each of which protrudes downward from a side part in a cover 21 covering at least the side of a space at the bottom part of the vehicle body 20 and extends in a length direction of the railway vehicle 1. A lower end of the protruding member 30 is located below a bottom surface of a portion excluding a portion corresponding to the storage space S of the vehicle body 20.SELECTED DRAWING: Figure 1

    【課題】台車を格納するために鉄道車両の車体の底部に設けられた格納空間において発生する圧力変動のうち少なくとも低周波域のものを低減させる、新規な圧力変動低減構造を提供する。【解決手段】台車10を格納するために鉄道車両1の車体20の底部に設けられた格納空間Sにおいて発生する圧力変動のうち少なくとも低周波域のものを低減させる、圧力変動低減構造であって、車体20の底部の空間の少なくとも側方を覆うカバー21における側方部から下方に突出すると共に鉄道車両1の長さ方向に延びる凸部材30を備え、凸部材30の下端は、車体20における格納空間Sに対応する部分以外の部分の底面より下方に位置する。【選択図】図1
