PROBLEM TO BE SOLVED: To provide a structure of a movable body in which noise and vibration are reduced.SOLUTION: A structure of a movable body 1 such as a vehicle body of railway vehicle having a space part in which a transportation object is accommodated comprises: an external structure 100 which receives a load inputted to the movable body from the exterior and of which a cross-sectional shape in a plane face orthogonal to a travel direction is so formed as to be a substantially closed cross section; and an interior structure 200 which is provided in the exterior structure, of which a cross-sectional shape in a plane face orthogonal to the travel direction is so formed as to be a substantially closed cross section, and inside which a space part is provided. The interior structure is so configured as to be fitted to the exterior structure in the state that the interior structure can be displaced relatively to the exterior structure.SELECTED DRAWING: Figure 1
【課題】内部の騒音及び振動を低減した移動体の構造を提供する。【解決手段】輸送対象物が収容される空間部を有する鉄道車両用車体等の移動体1の構造を、移動体に対して外部から入力される荷重が負荷されるとともに、進行方向と直交する平面における断面形状が実質的に閉断面となるように形成された外部構造体100と、外部構造体の内部に設けられ進行方向と直交する平面における断面形状が実質的に閉断面となるように形成され内側に空間部が設けられた内装構造体200とを備え、内装構造体は、外部構造体に対して相対変位可能な状態で外部構造体に取り付けられる構成とする。【選択図】図1
