To provide a window structure of a railway vehicle capable of achieving both the improvement of sound insulation performance against a sound at a resonance transmission frequency and the securement good visibility and lighting property.SOLUTION: A window structure 1 is a window structure of a railway vehicle in which a multi-layer window 3 is arranged in an opening part 2a provided at a side structure 2. In the window structure 1, the side structure 2 has an outer plate 4 and an inner plate 5 which are arranged at intervals so as to face each other and define the opening part 2a. The multi-layer window 3 comprises a pair of window plates 6, 7 arranged between the outer plate 4 and the inner plate 5 to cover the opening part 2a and a Helmholtz resonator 9 arranged in an overlapping region R where the pair of window plates 6, 7 and the outer plate 4 and the inner plate 5 are overlapped each other between the pair of window plates 6, 7.SELECTED DRAWING: Figure 2
【課題】共鳴透過周波数の音に対する遮音性能の向上と、良好な視界や採光性の確保とを両立できる鉄道車両の窓構造を提供する。【解決手段】窓構造1は、側構体2に設けられた開口部2aに複層窓3が配置された鉄道車両の窓構造である。窓構造1では、側構体2は、互いに向かい合うように間隔を空けて配置され、開口部2aを画定する外板4及び内板5を有する。複層窓3は、開口部2aを覆うように外板4と内板5との間に配置された一対の窓板6,7と、一対の窓板6,7の間において、一対の窓板6,7、外板4及び内板5が互いに重なり合う重なり領域Rに配置されたヘルムホルツ共鳴器9と、を有する。【選択図】図2
