Abstract

Provided is a method for manufacturing a gripping tool for gripping a workpiece with top jaws () attached to a plurality of master jaws () attached to a gripping tool body (). A first positioner () that determines the distance of the top jaw from the center axis of the top jaw when the top jaw is attached to the master jaw is formed in a direction perpendicular to a slide direction in a surface of the master jaw. The method includes a step of attaching the plurality of master jaws to the gripping tool body, a step of gripping a shaping plug () by sliding the plurality of master jaws toward the center axis, and a step of finishing, in the surface of the master jaw, the first positioner extending in the direction perpendicular to the slide direction.
