Abstract
This invention provides a bottom end stop for a slide fastener in which an engaging/disengaging operation can be achieved easily and quickly without an interruption by a slider pull tab while engaging/disengaging the bottom end stop. A joining piece is attached to the bottom of one stringer and a fitting piece is attached to the bottom of the other stringer. The joining piece includes a holding portion that includes an insertion concave groove, a base portion formed on the holding portion, and a male engaging portion comprising a pair of elastically deformable leg portions provided on the base portion. The fitting piece includes a insertion portion which can be fit into the insertion concave groove of the joining piece, a base portion provided on the insertion portion, and a female engaging portion comprising a hole portion, in which the leg portions of the male engaging portion can be fit, provided on the base portion of the fitting piece. In operation, the slider is inserted into the holding portion to engage the female and male engaging portions. Then, the insertion portion is rotated and fit into the insertion concave groove so that the slider can slide. Since the female and male engaging portions are engaged on an opposite surface to a side in which a single pull tab of the slider exists, even when the pull tab of the slider hangs downward, the engaging operation between the female and male engaging portions is never obstructed.
