PROBLEM TO BE SOLVED: To facilitate the mounting and dismounting of a socket, by providing a projection, for engaging with an apparatus holder, on the outer side of a screw socket, to arrange the projection in the direction same as that of the outer side surface of the long side of a hook sealing. SOLUTION: A socket part 6 is integrally connected to a hook sealing part 4a to be hung, and a projection 7, for engaging with an apparatus holder, is provided on an outer side to be arranged on a position in a direction same as that of the outer side surface of the long side 4b of the hook sealing part 4a. The hook sealing part 4a is formed so that the parting line L of a die can pass the nearly center of a side surface, wherein the short sides 4c of the hook sealing part 4a is adopted as edge parts, to be parallel to the side surfaces, wherein long side 4b are adopted as side sides, and so that the die can be slid in the respective directions of arrows A-D. When the hook sealing part is gripped by a hand to be rotated, the hindering of the projection 7 to the position of fingers can be eliminated, and the structure of the die can be simplified to facilitate the manufacture of the die. |
