ABSTRACT:
A slider for use in a slide fastener prevents jamming of a foreign matter within the slider between fastener elements and inner element-guide portions of the slider. The slider has a diverging end and a contracted end, and the diverging end has two openings which are partitioned by an interconnecting web. The two openings lead to two channels which are joined together in the half portion of the slider on the side close to the aforesaid contracted end. The separated fastener elements secured to fastener tapes, respectively, and introduced through the aforesaid channels into the slider are brought into engagement with each other in the aforesaid half portion of the slider. In such a case, a foreign matter, such as a piece of cloth, often jams between the fastener elements and the inner element-guiding portions of the slider. To prevent this, the slider according to the invention provides lip portions which are turned in from the open edges of the aforesaid channels, thereby reducing clearances between the fastener elements and the element-guiding portions of the slider. These lip portions are made of a wear-resistant resilient material.
