AIRTIGHT STRUCTURE OF DOOR
To provide an airtight structure of a door which can secure airtightness.SOLUTION: An expansion rubber 300 is arranged on a partition structure 1 along a circumference of an opening 121 for allowing a passenger to get on or off. When doors 200L, 200R are arranged at a closing position for closing the opening 121, compressed air is supplied to an internal space S of the expansion rubber 300 from a supply/discharge device. This expands the expansion rubber 300, and an abutted wall 321 of the expansion rubber 300 is abutted on back surfaces of the doors 200L, 200R. As a result, bearing pressure can be applied to a sealing surface of the expansion rubber 300 so that airtightness can be secured.SELECTED DRAWING: Figure 4
【課題】気密性を確保できる扉の気密構造を提供すること。【解決手段】区画構造１には、乗客が乗降するための開口部１２１の周縁に沿って膨張ゴム３００が配設される。開口部１２１を閉鎖する閉鎖位置に扉２００Ｌ，２００Ｒが配置されると、給排装置から膨張ゴム３００の内部空間Ｓに圧縮空気が供給される。これにより、膨張ゴム３００が膨張され、膨張ゴム３００の被当接壁３２１が扉２００Ｌ，２００Ｒの背面に当接される。その結果、膨張ゴム３００のシール面に面圧を付与でき、気密性を確保できる。【選択図】図４
