FASTENING STRUCTURE AND AIRCRAFT

To provide a new fastening structure capable of reducing the generation of an arc itself.SOLUTION: In a fastening structure 1 of the present invention, a first member 10 and a second member 20 are overlapped such that the central axes C of a first insertion hole 15 and a second insertion hole 25 thereof coincide with each other and a fastener pin 31 of a fastener 30 passes through the first insertion hole 15 and the second insertion hole 25. A male screw 33 provided at the tip of the fastener pin 31 is exposed at a fastener screw side FTS other than the back side 23 of the second member 20. A female screw 39 of a collar 37 is attached to the male screw 33 so that the fastening structure 1 is formed, in which the first member 10 and the second member 20 are firmly fixed to each other. The fastening structure 1 includes a second chamfer 27 in the front side 21 of the second member 20.SELECTED DRAWING: Figure 1 【課題】アークの発生自体を低減できる新たなファスニング構造を提供すること。【解決手段】本発明のファスニング構造１は、第一部材１０と第二部材２０が、互いの第一挿通孔１５と第二挿通孔２５の中心軸Ｃが一致するように重ね合わされ、ファスナ３０のファスナピン３１が第一挿通孔１５、第二挿通孔２５を貫通するように挿通される。ファスナピン３１の先端に設けられる雄ねじ３３は第二部材２０のうら面２３よりもファスナねじ側ＦＴＳに露出される。この雄ねじ３３にカラー３７の雌ねじ３９を付けることで、第一部材１０と第二部材２０が強固に固定されたファスニング構造１が構成される。ファスニング構造１は、第二部材２０のおもて面２１に第二面取り２７を備えている。【選択図】図１
