Abstract: Provided is a method for manufacturing a caulked assembly that is capable of manufacturing the caulked assembly at a low cost, preventing reduction of the strength of a columnar body caused by a circumferential groove, preventing deformation of the columnar body, and assembling a slimmer columnar body with a plate-like body. A mounting hole 10 for inserting and assembling a columnar body 2 is provided in a metallic plate-like body 1, and a thick portion 11 is formed along an inner circumferential edge of the mounting hole 10. Thereafter, as shown in FIG. 1(a), the columnar body 2 is inserted into the mounting hole 10 of the plate-like body 1 so that the plate-like body 1 is set in an assembly position on an outer circumferential surface of the columnar body 2.

Abstract: The present invention provides a caulked assembly to be manufactured at low cost, and maintain sufficient caulking strength, and the manufacturing method and apparatus thereof. The manufacturing method comprises steps of forming a mounting hole for inserting and assembling a columnar body in a metal plate body, and forming a thick part along an inner circumferential edge of a mounting hole; forming a circumferential groove with a predetermined depth at an assembled position of a outer circumferential surface of the columnar body inserted into the mounting hole; inserting the columnar body into the mounting hole to set to the assembled position where the thick part is opposed to the circumferential groove; 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.
