More Information
Summary:The slide fastener has a separable bottom end stop, and the separable bottom end stop has at least an insert pin and a box pin. The insert pin has an escape portion provided with an inclined surface or a curved surface along which the thickness dimension of the insert pin decreases in the direction of the tape width toward the side edge that faces the box pin, the escape portion being positioned in the front-end corner portion of a first-surface of the insert pin, the corner portion being positioned along the edge that faces the box pin. This allows the escape portion of the insert pin to function as an interference prevention means, efficiently prevent chain failure in an element row when the slide fastener is bent into a U-shape, and maintain stable engaging.
