Abstract
An end stop which does not induce separation or deterioration in its mounting portion by fusing part thereof. A linear fastener element row formed of synthetic resin is mounted on a side edge of a fastener tape, and a rod-like body of synthetic resin is inserted into the interior of plural fastener elements located at a final end of the element row. A fused portion is proved by welding only a side of an outer end portion of the rod-like body while a non-fused portion is formed without welding a side of an inner end portion, so the end stop as a top or bottom end stop is produced. The non-fused portion absorbs an impact when a slider collides with the end stop and induces no deterioration in sewing yarn and such. The fused portion integrates the end stop with fastener elements firmly, so a rigid structured end stop is completed.

An end stop for a slide fastener, wherein a linear fastener element row of synthetic resin is mounted on a side edge of a fastener tape;
- a rod-like body of synthetic resin is insened into a coupling space portion located in an inside of coupling heads in plural fastener elements located at an end of the fastener element row;
- first and second fused portions are provided by fusing several fastener elements of the plural fastener elements in which the rod-like body is inserted with the rod-like body;
- and a non-fused portion is formed without fusing the fastener elements of the plural fastener elements in which the rod-like body is inserted except the fastener elements fused with the rod-like body in the first and second fused portions so as to form the end stop, and wherein
- the first fused portion is provided on an outer end portion of the rod-like body, the second fused portion is provided on an inner end portion of the rod-like body, and the non-fused portion is provided between the first fused portion and the second fused portion.
