PROBLEM TO BE SOLVED: To enhance the sound insulation performance of a movable sound insulation cover without deteriorating the design flexibility of a vehicle body.SOLUTION: There is provided a sound insulation device for a railway vehicle insulating noise generating at a current collector mounted on a vehicle roof. The device is equipped with plural sound insulation covers operable between a deployment state standing in a state along a vehicle longitudinal direction at a lateral side of the current collector and a storage state stored in a storage space inside the vehicle, and at least one drive mechanism. The plural sound insulation covers are mutually in the state adjacent to each other in the deployment state, and are in the state mutually overlapping with each other in a view from a vehicle width direction in the storage state. The total length of the plural sound insulation covers in the vehicle longitudinal direction in the storage state is shorter than that of the plural sound insulation covers in the deployment state in the vehicle longitudinal direction.SELECTED DRAWING: Figure 1

    【課題】車体の設計自由度を低下させることなく、可動式の遮音カバーの遮音性能を高める。【解決手段】車体の屋根上に搭載された集電装置で生じる騒音を遮音する鉄道車両の遮音装置であって、前記集電装置の側方で車両長手方向に沿った状態で起立する展開状態と、前記車体の内部の収納空間に収納される格納状態との間で動作可能な複数の遮音カバーと、前記複数の遮音カバーを動作させる少なくとも1つの駆動機構と、を備え、前記複数の遮音カバーは、前記展開状態では互いに車両長手方向に隣接し、前記格納状態では前記車幅方向から見て互いに重なり、前記格納状態における前記複数の遮音カバーの全体の前記車両長手方向の長さは、前記展開状態における前記複数の遮音カバーの全体の前記車両長手方向の長さよりも短い。【選択図】図1
