Abstract: 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.

Abstract: A buckle of the present invention includes a male member (A) and a female member (B). The male member includes: a base (10); a pair of legs (20) that project from the base; and engaging portions (25) that are provided on the legs and are engageable with the female member. The base includes a projecting portion (14) that projects in a projecting direction of the legs. A recess (15) is formed on a front or rear surface of the projecting portion. The recess (15) includes a front end (15A) and a rear end (15B) in an inserting direction of the male member (A). The front end substantially has the same height as the front surface of the base. The rear end is substantially lower than any other position on a surface connecting the front end and the rear end.

Abstract: A bottom end stop for a slide fastener constituted of an upper and lower plate and a base portion, comprising the upper plate formed of a flat undeformable plate and having a flange formed on each of both side ends thereof by bending each side end at right angle, a groove portion having a circular section provided in the center of the rear face of the lower plate, an arm portion provided on each of both sides of the groove portion such that the arm portion departs gradually from the upper plate, centers of the upper and lower plates connected through a base portion, a core portion of a fastener tape sandwiched between the upper and lower plates on right and left sides of the base portion, and the arm portion deformed toward the upper plate plastically to attach the bottom end stop, thereby enabling a decoration such as letters, marks or patterns to be expressed simply on the surface of the bottom end stop, and preventing generation of cracks in the lower plate when the bottom end stop is attached.
