Claims

[Scope of utility model registration request]

A rivet characterized in that an indication indicating the permissible eccentricity range of the rivet head is provided on a circle that is concentric with the rivet hole and has a slightly larger diameter than the diameter of the rivet head, which is normally formed concentrically with the rivet hole on the surface where the rivet's rivet head comes into contact. Fastening structure.
