Summary:To provide an interior structure of a railway vehicle which easily achieves both a suppressing effect against noises propagating in a passenger room space and a passenger room space securing, and elevates a comfort-ability there.SOLUTION: An interior structure constituting a space which is formed in a bodywork of a railway vehicle and in which passengers can stay is composed of plates that have at least one or more openings and are provided with layers separated with a prescribed separation along a space side inner than the bodywork, a support member connecting the plates to part the layers on the front face in a space side in the bodywork and sound absorption units made of at least one fiber sound absorption materials in layers parted by the support members. Also, the interior structure has a sound insulation plate arranged between the plate and the bodywork, and a supporting material provided on the plate-side surface of the sound insulation plate and connecting the plates to part layers which have prescribed separations between the sound insulation plate and the plates. The sound insulation plates constituting the sound absorption unit are installed in the space-side of the bodywork with a prescribed separation.SELECTED DRAWING: Figure 9 【課題】 車内空間に伝わる騒音に対する低減効果を高めることと、車内空間の確保と、を両立させ易く、快適性を向上できる鉄道車両の内装構造を提供する。【解決手段】 鉄道車両の車体の内部に形成された乗客が滞在可能な空間を構成する内装構造において、車体より内部の空間側に沿って所定の間隔をもつ層を設けて備えた少なくとも１以上の開口部を有する板材と、車体の内部の空間側の表面には層を分断するように板材につなぐ支持材と、支持材によって分断された層の内部の少なくとも１つは繊維質の吸音材よりなる吸音ユニットと、で構成される。さらに、板材と車体の間に配設された遮音板と、その遮音板の板材側表面には遮音板と板材の間に所定の間隔を設けて備えた層を分断するように板材につなぐ支持材と、を備え、吸音ユニットを構成する遮音板が車体の空間側に所定の間隔を設けて配置される。【選択図】 図９
