Title:
スライドファスナー
Document Type and Number:
Japanese Patent JP5234685
Kind Code:
B2
Abstract:
A separation portion having weakened tensile rupture strength of an element having tensile rupture strength reduced to 40 N or below is formed in a range of a first fixing portion of a first leg portion to a second fixing portion of a second leg portion via a coupling head portion, in at least a part of elements of the slide fastener. With this arrangement, when excessive lateral pulling force is applied to the slide fastener, cleavage lateral pulling force that causes cleavage of the slide fastener can be reduced. By adjusting tensile rupture strength of the elements, cleavage lateral pulling force of the slide fastener can be set within a predetermined range.
