Title: BUTTON-MOUNTING MEMBER
Abstract:
Disclosed is a button-mounting member that has a hollow post, which has good fabric-penetrating properties, and which is not susceptible to piercing defects, nor susceptible to post-buckling defects or button-mounting defects. The button-mounting member (10, 40) has a base (11) and a post (20, 50) that protrudes from the base (11). The post (20, 50) is hollow and comprises a triangular pyramid-shaped or quadrangular pyramid-shaped post tip (21, 51) and a cylindrical post body (22, 52) that extends between the post tip (21, 51) and the base (11). The post tip (21, 51) has three or four conical faces (21a, 51a) and three or four ridges (21b, 51b) between the conical faces (21a, 51a), and the ridges (21b, 51b) function as an outer casing frame for the post tip (21, 51). The post body (22, 52) has long slits (25, 55) or grooves (75) oriented axially at positions in the circumferential orientation corresponding to the ridges (21b, 51b).
