CAULKING-FASTENED COMPONENT, METHOD OF FASTENING THE CAULKING-FASTENED COMPONENT, AND METHOD OF MANUFACTURING THE CAULKING-FASTENED COMPONENT

摘要

A purpose of the present application is to provide a caulking-fastened component, a method of fastening the caulking-fastened component, and a method of manufacturing the caulking-fastened component, whereby a manufacturing cost of a fastening structure between the caulking-fastened component and a counterpart component can be reduced. One aspect of the invention provides an annular caulking-fastened component to be fastened to a counterpart component by caulking, the caulking-fastened component including a notch formed in an inner peripheral edge portion at one end side in a center axis direction, the notch being to be fixed to the counterpart component by caulking; and at least one of an inner-peripheral stepped portion formed between an inner peripheral surface and the inner peripheral edge portion and outward from the inner peripheral surface in a radial direction and an end-face stepped portion formed between an end face at one end side in the center axis direction and the inner peripheral edge portion and from the end face toward the other end side in the center axis direction.
