部材とからなることを特徴とするリベツト構造。[Scope of Claim for Utility Model Registration] A structure of a rivet for fastening a first fastened member and a second fastened member, the rivet having a hollow part and a large diameter hole formed in the first fastened member. a hollow insertion part to be inserted; an opening provided in the hollow insertion part for opening the hollow part to the large diameter hole of the first fastened member; a first rivet comprising an outer flange portion that abuts around the large diameter hole of the first fastened member when the shaped insertion portion is inserted into the large diameter hole of the first fastened member; a deformable cylindrical shaft part that is inserted into the small diameter hole of the first rivet and has one end facing into the hollow part from the opening of the hollow insertion part of the first rivet; an outer flange portion that abuts around the small diameter hole of the second fastened member when the cylindrical shaft portion is inserted into the small diameter hole;
a second rivet including a through hole that continuously passes through the cylindrical shaft portion and the outer flange in the axial direction; a rod portion inserted into the through hole of the second rivet; and a tip end of the rod portion. The rod part is inserted into the through hole of the second rivet and protrudes from the cylindrical shaft part and is positioned in the hollow part of the hollow insertion part of the first rivet, and when fastened,
By pulling the rod part, it is press-fitted into the tip side of the through hole of the second rivet, causing one end of the cylindrical shaft part to bulge outward in the radial direction and deform, thereby moving the first rivet toward the second fastened member. A rivet structure comprising: a pulling member having a bulging portion that engages the bulging deformed portion from inside around the opening of the hollow insertion portion for pressing.
