Abstract

A slide fastener (10) is provided with an extraction member (80) provided to a first fastener stringer (16) and also with a retaining member (90) provided to a second fastener stringer (17), and the extraction member (80) and the retaining member (90) are provided so as to face each other. The retaining member (90) is provided with a positioning section for positioning and holding a slider (50). The extraction member (80) is provided with a side-pull contact body (86). The side-pull contact body (86) comes in contact with a flange of a slider (50) when a side-pull force acts on the side-pull contact body (86), and the side-pull contact body (86) comes out of a rear opening of the slider (50) when the extraction member (80) is rotated and moved. This enables the slider (50) to be positioned and held at an engagement and sliding end. When the extraction member (80) is rotated in the direction in which the extraction member (80) is separated from the retaining member (90), the side-pull contact body (86) can be stably extracted from the rear opening of the slider (50) and the slide fastener can be easily set to an open state.

Description

technical field [0001] This invention relates to the slide fastener of a top open type which can make a slide fastener into an opened state without sliding operation of a slider. Background technique [0002] Conventionally, there is known a slide fastener in which a slide fastener in which a pair of left and right engaging element rows are in an engaged state can be instantaneously separated without performing a sliding operation of a slider. [0003] For example, a slide fastener with the following parts is disclosed in Japanese Publication No. 55-7135 (Patent Document 1): a pair of left and right zipper stringers, which are formed by disposing engaging element rows along the opposite end edges of the zipper strings; sliders, A pair of left and right engaging element rows are inserted through the engaging element guide passage of the slider, and the slider switches the engaging element row into an engaged state and a separated state by sliding along the engaging element ro...
