Patent ID: 7918007

Claim:
A method for manufacturing a caulked assembly of a metal plate body with a hollow or solid columnar body, the method comprising the steps of: forming a mounting hole for inserting and assembling the columnar body in the metal plate body and forming a thick part along an inner circumferential edge of the mounting hole; forming a circumferential groove with a predetermined depth at an assembled position of an outer circumferential surface of the columnar body inserted into the mounting hole; inserting the columnar body into the mounting hole of the metal plate body and setting the columnar body to the assembled position where the thick part and the circumferential groove are opposed to each other; and caulking for compressively pressing the thick part from an axial direction of the columnar body to plastically deform the thick part in a center direction of the mounting hole to bite the thick part into the circumferential groove of the columnar body opposed to the thick part.
