ABSTRACT:
A bottom end stop and a slider with a locking mechanism of a slide fastener chain which can be used for both the right side arrangement and the left side arrangement are provided. The slider includes a leaf spring showing a substantially U-shaped profile and having an end rigidly secured to a front part of the slider body, and the other end having a locking pawl arranged near the center thereof. The locking pawl resiliently projects into a guide groove for the engaging member located in the slider body. The bottom end stop includes an insert pin having a beveled escape area produced by cutting an edge of an upper outer surface of the insert pin facing the locking pawl, a groove formed on a surface facing a box pin of a box so as to engage with a ridge portion of the box pin when the insert pin is inserted into the box. The locking pawl is arranged between a top surface of the box pin and a bottom surface of the abutting portion provided at the top of the insert pin and the locking pawl is adapted to slide on the escape area when the insert pin is inserted into the box at the right side thereof. And when the insert pin is inserted into the box at the left side thereof, the locking pawl does not relate to the operation of the insert pin, thus the insert pin is inserted freely.
