To seal a gap between a window panel and a frame without requiring high precision regarding dimensional shapes of the window panel and the frame, and in assembling, and further, without enlarging a fixing member of a clamp or the like, or deteriorating workability when fitting the window panel to the frame.SOLUTION: A seal member 10 for a window of an aircraft is arranged between a seal surface 222 of a panel member 2 pressed from the inside of a machine against a pressed surface 322 of a frame 3, and the pressed surface 322, in order to seal a gap between the seal surface 222 and the pressed surface 322. The seal member 10 includes: a first part 101 corresponding to an end 322A of the pressed surface 322; a second part 102 corresponding to an end 222B of the seal surface 222; and a curved part 100 curved in a no-load state. The curved part 100 is curved in a direction of retreating from either the seal surface 222 or the pressed surface 322, across a gap between the first part 101 and the second part 102 at a cross section intersecting a circumferential direction of the seal member 10.SELECTED DRAWING: Figure 4
【課題】窓パネルやフレームの寸法形状や組み立てに高い精度を必要とせず、また、クランプ等の固定部材の大型化や、窓パネルをフレームに取り付ける際の作業性の低下を招くことなく、窓パネルとフレームとの間を封止すること。【解決手段】航空機の窓用のシール部材10は、フレーム3の被押圧面322に対して機内側から押圧されるパネル部材2のシール面222と、被押圧面322との間に配置されてシール面222と被押圧面322との間を封止する。シール部材10は、被押圧面322の端部322Aに対応する第1部101と、シール面222の端部222Bに対応する第2部102と、無負荷の状態において湾曲している湾曲部100とを含む。湾曲部100は、シール部材10の周方向と交差する断面における第1部101および第2部102の間に亘り、シール面222および被押圧面322の一方から退避する向きに湾曲している。【選択図】図4
