METHOD FOR FASTENING PLATE-LIKE MEMBERS AND FASTENING STRUCTURE FOR PLATE-LIKE MEMBERS

摘要

A method for fastening plate-like members, including the steps of: forming a convex part on a surface of one plate-like member; forming a through-hole which has a larger diameter than a diameter of the convex part in another plate-like members; after inserting the convex part through the through-hole, pressing a top surface of the convex part with a first pressurizing tool which includes at least one pointed end portion having a smaller contour than a contour of the convex part to make a cut matching the at least one pointed end portion of the first pressurizing tool at the top surface of the convex part; further pressing to expand an outer portion of the cut outwardly by means of a second pressurizing tool; and fastening the two plate-like members mutually by sandwiching in the vicinity of the through-hole of the other plate-like member by means of an expanded portion formed on the convex part and the surface of the one plate-like member.
