<p>In a male or female snap button (10, 50, 70) including a base (11, 51, 71) and a mounting opening (13, 53, 73), a cylindrical protrusion (14, 54, 74) is provided around the mounting opening. When the male or female snap button (10, 50, 70) is being mounted to a fabric (1), after a post (22) of a button fastener (20) has passed through the fabric (1) and then the mounting opening (13, 53, 73), the post (22) is swaged by an upper die. At this time, the protrusion (14, 54, 74) of the male or female snap (10, 50, 70) is crushed between the post (12) and the base (11, 51, 71). Thereby, a part of a load as imposed on the male or female snap button (10, 50, 70) can be absorbed by the deformation of the protrusion (14, 54, 74).</p> |
