To provide a body structure of a railway vehicle including a heat insulating performance and a sound insulating performance.SOLUTION: A body structure 10 includes a structure body 11 and an interior material 13. The interior material 13 is disposed at a position closer to an internal space of a railway vehicle than the structure body 11. A bag body is disposed between the structure body 11 and the interior material 13. Gas is encapsulated inside of a membrane of the bag body. When the bag body is vibrated by the vibration of the structure body 11, microvibration in a membrane thickness direction is caused at a plurality of continuous portions in the membrane of the bag body.SELECTED DRAWING: Figure 2
【課題】断熱性能を備えつつ、遮音性能を備える。【解決手段】構体構造10は、構体11と内装材13とを備える。内装材13は、構体11より鉄道車両の内部空間に近い位置に配置される。構体11と内装材13との間に、袋体が配置されている。袋体の膜の内部に、気体が封入されている。構体11が振動することにより袋体が振動したとき、袋体の膜において、連続した複数の箇所で、膜の厚み方向の微振動が起こる。【選択図】図2
