<p>PROBLEM TO BE SOLVED: To easily work the structure and the shape of a socket by constituting a stopper for a slider of a stop ring holding part projecting outward the socket and formed by folding back the circumferential wall of the socket and a stop ring fitted to the slider side. SOLUTION: A stopper 1k specifying a rear stop position of a slider 6 projects outward a socket 1. The stopper is constituted of a stop ring holding part 1i having a structure formed by folding back the circumferential wall of the socket 1 and a stop ring 10 composed of a snap ring or the like fitted to the slider 6 side of the stop ring holding part 1i. When the socket 1 is molded of a sheet material by press working with no cutting work, a stop ring holding part 1i can be formed by buckling work in a continuous process of deeply drawing the socket 1 from the sheet material. This constitution can omit another process of machining a groove by another machine after the deep drawing of the sheet material like the conventional techniques.</p> |
