PROBLEM TO BE SOLVED: To provide a seal structure for an aircraft, capable of surely sealing with an elastic seal, an interval between members having large relative displacement even when a seal abutting surface of the member with which the elastic seal comes into contact is not sufficiently secured, and capable of reducing a burden of maintenance such as inspection and exchange of the elastic seal.SOLUTION: A seal structure 30 includes: a plate spring seal 31 sealing an interval between a first member 10 and a second member 20 through elastic deformation between the first member 10 and the second member 20 during a stationary time when the first member 10 and the second member 20 do not relatively move; and a second elastic seal 32 not-sealing an interval between the first member 10 and the second member 20 during a stationary time. When the first member 10 and the second member 20 come close to each other, and the first member 10 and the second member 20 relatively move in a direction where the first elastic seal 31 is elastically deformed, the second elastic seal 32 seals an interval between the first member 10 and the second member 20 through elastic deformation between the first member 10 and the second member 20.SELECTED DRAWING: Figure 5

    【課題】弾性シールが接触する部材のシールあたり面を十分に確保できないとしても、相対的な変位が大きい部材同士の間を弾性シールにより確実に封止することができると共に、弾性シールの点検や交換等の整備の負担を軽減することも可能な航空機用のシール構造を提供すること。【解決手段】シール構造30は、第1部材10と第2部材20とが相対的に動いていない静止時に、第1部材10と第2部材20との間で弾性変形していることで第1部材10と第2部材20との間を封止する板バネシール31と、静止時に、第1部材10と第2部材20との間を封止していない第2弾性シール32とを備えている。第1部材10と第2部材20が近付き、第1弾性シール31が弾性変形する向きに第1部材10と第2部材20とが相対的に動いた時に、第2弾性シール32は、第1部材10と第2部材20との間で弾性変形することで、第1部材10と第2部材20との間を封止する。【選択図】図5
