Method for Mounting Male Snap Button, Male Snap Button, Male Snap Button Structure, Method for Mounting Female Snap Button, Female Snap Button, and Female Snap Button Structure

摘要

In a male or female snap button including a base and a mounting opening, a cylindrical protrusion is provided around the mounting opening. When the male or female snap button is being mounted to a fabric, after a post of a button fastener has passed through the fabric and then the mounting opening, the post is swaged by an upper die. At this time, the protrusion of the male or female snap is crushed between the post and the base. Thereby, a part of a load as imposed on the male or female snap button can be absorbed by the deformation of the protrusion.
