Abstract

The slide fastener is provided with: a pair of fastener tapes (2); multiple links (3) that are fixed along the longitudinal direction of the fastener tapes (2) and have a groove (34) for accommodating the opposite fastener tape (2) therein; and a slider (4) that engages or separates the multiple links (3). The multiple links (3) are provided with a front surface part (31) and a back surface part (32), which are disposed so as to be shifted from each other in the longitudinal direction of the fastener tape (2) with the fastener tape (2) therebetween. The front surface part (31) and the back surface part (32) are provided with convex engaging parts (311, 321) and concave engaging parts (312, 322). When the multiple links (3) are engaged, the multiple links (3) are disposed in a line along the longitudinal direction of the fastener tapes (2). Between the fastener tapes (2), the multiple links (3) are disposed with axial symmetry with respect to a center line (A), which passes through the convex engaging parts (311, 321) and the concave engaging parts (312, 322).

Description

Technical field [0001] The present invention relates to a zipper. Background technique [0002] With regard to a zipper, a plurality of fastener elements are attached to the opposite tape side edges of the two tapes, a slider is inserted into the row of the fastener element and the slider is slid along the row of the fastener element, thereby meshing the row of the fastener element Or separate. As such a slide fastener, for example, the following slide fastener is described in Japanese Utility Model Publication No. 30-15033: a fastener element (connector) is arranged on a fastener tape, and the fastener element is provided on both sides for storing two When the grooves of the fastener tape are engaged, the fastener elements are arranged in a row at the boundary portion of the two fastener tapes. By arranging the fastener elements in one row on the fastener tape, it is possible to obtain a more beautiful appearance compared to a normal slide fastener in which the fastener elemen...
