摘要： PROBLEM TO BE SOLVED: To further improve lightning-resistant performance by surely and inexpensively sealing an arc.SOLUTION: By disposing a ring member 50A formed into an L shape in section on a step 27 formed in a collar 26, the ring member 50A is pressed by the surface 22b of a structure member 22 and the outer peripheral surface of a fastener pin 25 to be adhered thereto. Thus, one end of a space connected to a clearance between the inner peripheral surfaces of the holes 21a and 22a of a wing panel 21 and the structure member 22 and the outer peripheral surface of the fastener pin 25 is closed by the ring member 50A. The tip 52a of the rising part 52 of the ring member 50A in an L shape in section is positioned nearer to the outer peripheral side than the corner 22C of the inner peripheral side of the structure member 22. Thus, the concentration and acting of stress on the corner 22C of the inner peripheral side of the structure member 22 via the ring member 50A is prevented.
摘要翻译：要解决的问题：为了进一步提高防雷性能，确保低成本密封。解决方案：通过在形成在轴环26中的台阶27上设置形成为L形的环形构件50A，环构件50A为被结构构件22的表面22b和紧固件销25的外周表面压紧以被粘附到其上。因此，连接到翼片21的孔21a和22a的内周表面与结构构件22和紧固件销25的外周表面之间的间隙的一端由环构件50A封闭。环状构件50A的隆起部52的尖端52a位于比构成构件22的内周侧的角部22C更靠近外周侧的位置。因此，应力的集中和作用防止了通过环状构件50A的结构构件22的内周侧的角部22C。
