Abstract
A joining method of a structure includes preparing a first member including a first portion provided with a first hole and a second portion provided with a second hole, a second member, a die, and an elastic member, inserting the second member into the first hole, inserting the elastic member into the second member, in a state where one end of the second member in an axial direction is located between the first portion and the second portion, compressing and expanding the elastic member in the axial direction, thereby expanding and deforming the second member at a portion passing through the first hole to be swaged and joined to the first portion. The die includes a support surface for applying a compressive force from the die to the elastic member through the second hole. The support surface is perpendicular to an axial direction of the elastic member.
