SLIDE FASTENER

[Problem] To provide a slide fastener configured so that, in a state in which a slide member for sealing is sandwiched between the two sliders of the slide fastener, the sealing properties between the slide member and the sliders are improved. [Solution] A slide fastener is provided with: a pair of fastener stringers (2); a pair of sliders (3) which opens and closes the pair of fastener stringers; and a slide member (4) which is provided so as to be slidable along the pair of fastener stringers and which is sandwiched between the pair of sliders. The slide member is provided with: an upper plate section (51) and a lower plate section (52), which are arranged above and below the facing side edges of the pair of fastener stringers; a connection section (53) which, between the facing side edges, connects the upper plate section and the lower plate section; cover sections (6) which protrude forward and rearward from the upper part of the upper plate section; and guide sections (54) which protrude forward and rearward from the lower part of the lower plate section. Receiving spaces (58) capable of receiving ends, in the front-rear direction, of the pair of sliders are provided respectively in the vertical gap between the front ends of both the cover section and the guide section and in the vertical gap between the rear ends of both the cover section and the guide section. Le problème décrit par la présente invention est de pourvoir à un élément de fixation coulissant conçu de telle sorte que, dans un état dans lequel un organe coulissant d'étanchéité est disposé entre deux curseurs de l'élément de fixation coulissant, les propriétés d'étanchéité entre l'organe coulissant et les curseurs sont améliorées. La solution est un élément de fixation coulissant pourvu : d'une paire de longerons de fixation (2) ; d'une paire de curseurs (3) qui ouvre et ferme la paire de longerons de fixation ; un organe coulissant (4) qui est agencé de façon à être coulissant le long de la paire de longerons de fixation et qui est disposé entre la paire de curseurs. L'organe coulissant est pourvu : d'une section de plaque supérieure (51) et d'une section de plaque inférieure (52), qui sont disposées au-dessus et au-dessous des extrémités latérales en face de la paire de longerons de fixation ; une section de raccordement (53) qui, entre les extrémités latérales en face, relie la section de plaque supérieure et la plaque de section inférieure ; des sections de couverture (6) qui font sai
