To improve the passenger's safety of a link member which comes in and out of an opening edge in an airtightness holding device of a side slide door with a link member that rotates by the operation of a cylinder device and presses the side slide door.SOLUTION: An airtightness holding device 10 of a side slide door comprises: a cylinder device 5 which is installed in a peripheral part 4 of a gateway 3 that is opened on a side structure 1 of a railway vehicle S and is opened and closed by the side slide door 2, and is operated by receiving hydraulic pressure; and a link member 7 which rotates in the inward/outward direction of the vehicle by the operation of the cylinder device and pushes the side slide door existing in a closed position 2a toward a close contact position 2b where the side slide door is closely contacted with an airtight packing member 61 fitted to the gateway. The link member comprises a roller member 8 which projects/recedes from an open edge 41 that is positioned on the vehicle outer side of the peripheral part and presses the side slide door, wherein a front restricted part 74 is formed which extends from a tip 71 to which the roller member is fitted toward a rotation center part 72 and projects toward a front R1 in the rotating direction from an outer peripheral surface of the roller member.SELECTED DRAWING: Figure 1

    【課題】シリンダ装置の作動により回動して側引戸を押圧するリンク部材を設けた側引戸の気密保持装置において、開口縁から出入りするリンク部材の乗客への安全性を高めること。【解決手段】鉄道車両Sの側構体1に開口され側引戸2によって開閉する出入口3の周縁部4内に設置され、流体圧を受けて作動するシリンダ装置5と、シリンダ装置の作動により車両内外方向へ回動して閉じ位置2aにある側引戸を出入口に装着した気密パッキング部材61と密着させる密着位置2bへ押圧するリンク部材7とを備えた側引戸の気密保持装置10である。リンク部材には、周縁部の車両外方に位置する開口縁41から出没して側引戸を押圧するローラ部材8を備え、当該ローラ部材が装着された先端部71から回動中心部72側へ延設され、ローラ部材の外周面より回動方向前方R1に向けて突出する前方規制部74が形成されている。【選択図】 図1
