Abstract
A button-fastening upper die includes a die body, a button-holding member and a cylindrical elastic member arranged between the die body and the button-holding member. By providing the elastic member with an annular recess recessed radially outward from the inner surface e.g. at the middle of the surface, the elastic member is sectioned into a thin-walled section located radially outward from the recess and two or more thick-walled sections remaining above and below the recess and the thin-walled section.
