Abstract
Official abstract text for this publication.
A cap capable of achieving enhanced safety by inhibiting the occurrence of sparks thereinside even if a lightning current has flowed through a fastener, a fastening structure using the same, and an aircraft including the fastening structure. The cap ( 27 ) is attached so as to cover a portion of a fastener ( 15 ) that couples an upper skin ( 3 ) of an aircraft and a stringer ( 11 ) located inside the upper skin. The covered portion projects through the stringer ( 11 ). An outer surface ( 33 ) of the cap that comes into contact with an interior space of the upper skin ( 3 ) is a curved surface, and the cap is made of a conductive material.
