Abstract
A punch includes a first caulking surface and a second caulking surface caulking margins of which axially differ in depth and sequentially formed in a peripheral direction, and includes a regulating surface opposing an outer peripheral surface of a caulking process portion to the first caulking surface of the first and second caulking surfaces, which has a deeper caulking margin, wherein the regulating surface regulates radial fillet movement by caulking of the caulking process portion to promote the fillet movement to the second caulking surface of the first and second caulking surfaces, which has a less deep caulking margin.
