Provided is a method for manufacturing a gripping tool for gripping a workpiece with top jaws (30) attached to a plurality of master jaws (20) attached to a gripping tool body (10). A first positioner (21, 24) 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 (70) 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.

A structure that is mounted to industrial equipment. This structure includes a jig, a first fixing member and a second fixing member, and a grip part. The industrial equipment has an attachment/detachment region for attaching and detaching the jig. The attachment/detachment region has a first space. The jig has a second space. The first fixing member is accomodatable in the first space. The second fixing member is accomodatable in the second space. The second fixing member is configured so that the jig can be attached to and detached from the attachment/detachment region by adjusting the degree of helical engagement of the first and second fixing members. The grip part is provided to at least one of the first fixing member and the second fixing member, and is configured grippable such that, in a state in which the degree of helical engagement has been loosened, the structure can smoothly be moved.
