WATERPROOF SLIDE FASTENER

WIPO Patent Application WO/2018/069971

A1

The slide fastener (1) according to the present invention has a slider (20) and a slider stopper member (30). A flange part (25) of the slider (20) has a linear section (26a) extending linearly from a rear opening and a curved section (26b) that is curved outward from an end of the linear section (26a). The slider stopper member (30) has: an insertion base part (34) disposed so as to straddle between right and left waterproof tapes (11); right and left insertion leg parts (35a, 35b) that extend from the insertion base part (34) toward an element row (12); and a flange pressure-welded part (41) disposed on an outer lateral face of the respective insertion leg parts (35a, 35b), wherein the flange pressure-welded part (41) has: a curved pressure-welded section (41b) and a linear pressure-welded section (41a) extending linearly from the rear end of the curved pressure-welded section (41b). This configuration enables the present invention to provide water-tightness even when the slider (20) is held at a slide-limit vicinity position away from the slide-limit position.
