To provide a pneumatic door device which grasps a door leaf thrust during door opening/closing by the pneumatic door device without movement of a detection part with a piston.SOLUTION: A pneumatic door device comprises a cylinder 20 which makes a piston connected to a door leaf installed in an entrance of a railway vehicle move by compressed air introduced into an air chamber, a second support part 17 movably supporting the cylinder body 20A, a fix wall 15 positionally fixed relative to the entrance, and a load cell 50 which is fixed to the fix wall 15 and detects a pressure applied to the fix wall 15 by the cylinder body 20A through a movement of the cylinder body 20A in a counter direction of the piston movement direction by the compressed air introduced into the air chamber.SELECTED DRAWING: Figure 4

    【課題】検出部をピストンと移動させることなく、空気式ドア装置によるドア開閉時のドアリーフの推力を把握する空気式ドア装置を提供する。【解決手段】空気式ドア装置は、空気室に導入された圧縮空気によって、鉄道車両の乗降口に設置されたドアリーフに連結されたピストンを移動させるシリンダ20と、ピストンの移動方向に沿って、シリンダ本体20Aを移動可能に支持する第2支持部17と、乗降口に対して位置を固定される固定壁15と、固定壁15に固定されるロードセル50であって、空気室に導入された圧縮空気によってピストンの移動方向と反対方向にシリンダ本体20Aが移動することで、シリンダ本体20Aが固定壁15に加える圧力を検出するロードセル50と、を備える。【選択図】図4
