摘要

PURPOSE: Provided is a concealed type slide fastener, in which, when a slider is pulled up towards a top end stop to close the slide fastener, an element-guiding portion formed on a guidepost is well prevented from impinging or contacting against the top end stop made of resin attached to a folded edge of the fastener tape so that the top end stop is free from damages and operates in smooth and stable condition for a prolonged period of time. CONSTITUTION: A concealed type slide fastener comprises: a pair of fastener tapes(10) having opposed longitudinal edges(11) folded thereon; two rows of fastener elements(12) mounted on the opposed longitudinal folded edges; a top end stop(14) mounted on the upper end of fastener element row; a slider(1) reciprocally movable along the fastener element rows. The slider comprises a slider body and a guidepost(3) mounted on the slider body. The guide post(3) comprises a sliding surface and an overhanging element-guiding portion extending from the upper end of the sliding surface. The concealed type slide fastener further includes unit for preventing contact between the element-guiding portion and a corner of the top end stop(14).
