PROBLEM TO BE SOLVED: To provide a pinching sheet capable of keeping the temperature of a structural member at an allowable temperature or lower by suppressing heat conduction from a high temperature duct to the structural member.SOLUTION: A pinching sheet 20 according to the present invention is held between a flange 12 provided to an extraction duct 10 formed through the partition wall 7 of an aircraft and a bulkhead panel 71 to which the flange 12 is fastened. The pinching sheet 20 is provided with: a first portion arranged near the shaft of each of rivets 13 provided to a plurality of positions in the pinching sheet; and a second portion extending between the first portions. The first portion receives a fastening load, and the second portion has heat conductivity lower than that of the first portion.SELECTED DRAWING: Figure 2

    【課題】高温ダクトから構造部材への熱伝導を抑制することにより、構造部材の温度を許容温度以下に維持することが可能な挟入シートを提供する。【解決手段】本発明の挟入シート20は、航空機の隔壁7を貫通する抽気ダクト10に備えられたフランジ12と、フランジ12が締結される隔壁パネル71との間に挟み入れられる。挟入シート20における複数の位置に与えられるリベット13の各々の軸の近傍に配置される第1部分と、第1部分同士の間で延在する第2部分とを備える。第1部分は、締結の荷重を受け持ち、第2部分は、第1部分よりも熱伝導率が低い。【選択図】図2
