Claims

[Claims for Utility Model Registration] 1. The operating bolt 1 is attached to the engine E, and the operating part 2 of the operating bolt 1 is protruded outside the fuselage 3.
This engine is configured such that a lock nut 4 is screwed into a bolt operating part 2 facing the outside, and a sealing means 6 is attached over the lock nut 4 and the bolt operating part 2, so that the lock nut 4 can be prevented from rotating with respect to the bolt operating part 2. In the device for sealing an externally protruding portion of an operating bolt body, the sealing means 6 is constituted by a cap, a cap engaging portion 5 is formed in the lock nut 4, and the sealing cap 6 is inserted into the lock nut from the tip 10 side of the bolt operating portion 2. 4, and a sealing cap 6 is caulked to a cap engaging portion 5 of a lock nut 4. 2. According to claim 1, a smooth contact guide surface 7 is formed on the sealing cap 6, and the contact guide surface 7 is configured to be able to come into contact with at least one surface of the operating angle surface 11 of the lock nut 4. A sealing device for the external protrusion of the operation bolt of the engine described above. 3. The sealing cap 6 is provided with a guide cylinder part 8, and the guide cylinder part 8 is configured to be able to fit externally into contact with the bolt operation part 2 of the operation bolt 1. A sealing device for the engine operation bolt protrusion outside the fuselage.
