Abstract (en)
There is provided a button fastener which can reduce failures in fastening a button to a cloth, expand a range of sorts and thicknesses of cloths applicable, and reduce costs by thinning a post of the button fastener. The button fastener comprises a disk-like base (11) and a cylindrical post (12) which protrudes from the base (11). At a distal portion (12b) of the post (12), a plurality of hollows (14) and a plurality of bulges (15) are formed alternately in the circumferential direction. When the post (12) of the button fastener (20) is piercing the cloth (1) at the time of the button (20) being fastened to the cloth (1), the cloth (1) is being compressed by the top (13) of the post (12). In addition, each of the bulges (15) bites into the cloth (1) so as to press the cloth (1) in a concentrated manner while the cloth (1) penetrates into the hollows (14) so as to relieve the press. Thereby, parts of the cloth (1) corresponding to between the bulges (15) and the hollows (14) are made tense. With such presses and tensions or strong and weak presses alternate in the circumferential direction, it will be easier to cut the cloth (1) by the post (12).
