    • A separable bottom end stop for a slide fastener comprising a box, a box pin, and an insert pin. Protruding guide portions which protrude onto respective fastener tapes are integrally molded with respective side faces at tape-sides of the box pin and the insert pin via thin guide portions. The separable bottom end stop is formed of polyacetal resin, and a distance d between each outer side face of the box and each of the protruding guide portions and a protrusion height h of each of the protruding guide portions from a surface of each of the thin guide portions when the box pin and the insert pin are mounted into the box satisfy the equation (I): tan−1(d/h) ≧33°, where d≠0. The separable bottom end stop becomes hard to be broken with having excellent durability, despite using polyacetal resin which allows various coloring achieved easily, but is easy to be broken.
    • 一种用于拉链的可分离的底端止动件,包括箱体,箱形销和插入销。 突出到相应的拉链带上的凸出引导部分通过薄导向部分一体地模制在盒销和插销的带侧的相应侧面。 可分离的底端止动件由聚缩醛树脂形成,并且箱体的每个外侧面与每个突出导向部分之间的距离d和每个突出导向部分的突出高度h与薄的每个的表面 当箱形销和插入销安装到箱中时,引导部分满足等式(I):tan -1(d / h)> = 33°,其中d <> 0。 尽管使用可以容易地进行各种着色而易于破碎的聚缩醛树脂,但是可分离的底端挡块具有优异的耐久性,变得难以破坏。
