Provided is an occluding member for an opening with which a lightning protection function can be reliably maintained. The occluding member is provided with a first insulator (63) and a second insulator (65) between a door body (30) and a inner surface of a wing (11b) around an opening (12), and is configured in such a manner that, if the first insulator (63) drops out, the second insulator 65) gets sandwiched between an inner peripheral flat section (64) and the inner surface of the wing (11b). With the first insulator (63) tightly sandwiched between an outer peripheral flat section (62) and the inner surface of the wing (11b), the second insulator (65) is configured so as to face the inner surface of the wing (11b) with a prescribed clearance (C) therebetween. The outer peripheral flat section (62) is formed at a position further away from the inner surface of the wing (11b) than the leading edge surface (65a) of the second insulator (65) attached to the inner peripheral flat section (64). |
