PROBLEM TO BE SOLVED: To provide a double sliding sash capable of preventing sealed combustible gas from becoming a high pressure state, by surely sealing the combustible gas generated when a resin part of a door roller melts by heat of a fire.SOLUTION: A double sliding sash comprises a sash frame (a frame body) provided in an opening part of a structure and sashes 3A and 3B slidably provided inside the sash frame via a door roller part (a door roller) 8. A door roller storage part 58 capable of storing the door roller part 8 is formed on a bottom rail 5 of the sashes 3A and 3B. A meeting stile 6 and a stile 7 of the sashes 3A and 3B are formed with a hollow part for communicating with the door roller storage part 58 and a second door roller adjustment hole (a door roller adjustment hole) for communicating the hollow part and an external part, and are provided with a meeting stile lower heating foaming material (a first heating foaming material) 93 and a stile lower heating foaming material (a first heating foaming material) 95 foamable so as to block up the second door roller adjustment hole when heated and to maintain a communication state of the door roller storage part 58 and the hollow part.SELECTED DRAWING: Figure 3
【課題】火災の熱によって戸車の樹脂部分が溶融して発生した可燃性ガスを確実に封止し、封止された可燃性ガスが高圧状態となることを防止できる引違サッシを提供する。【解決手段】構造物の開口部に設けられるサッシ枠（枠体）と、サッシ枠の内部に戸車部（戸車）８を介してスライド可能に設けられるサッシ障子３Ａ，３Ｂと、を備え、サッシ障子３Ａ，３Ｂの下框５には、戸車部８を収容可能な戸車収容部５８が形成されていて、サッシ障子３Ａ，３Ｂの召合せ框６および縦框７には、戸車収容部５８と連通する中空部と、中空部と外部とを連通させる第２戸車調整孔（戸車調整孔）と、が形成されていて、加熱されると第２戸車調整孔を閉塞するとともに戸車収容部５８と中空部との連通状態を維持するように発泡可能な召合せ框下部加熱発泡材（第１加熱発泡材）９３および縦框下部加熱発泡材（第１加熱発泡材）９５が設けられている。【選択図】図３
