There is provided an end stop. A male member and a female member are configured to sandwich opposing side edge portions of a pair of fastener tapes from both sides thereof in an upward and downward direction. The male member includes a circular disk-shaped male base member and an inserting male portion. The female member includes a circular disk-shaped female base member and a receiving female portion. A facing surface of at least one of the male base portion and the female base portion is provided with a protrusion group. The protrusion group is configured so that a plurality of protrusions protruding to come at least in contact with each fastener tape are arranged to be spaced from each other at predetermined angles over the entire circumference of the facing surface along a circumferential direction thereof.

In a slide fastener, a fastener tape is woven with a single-woven structure, and in the fastener tape, a double-woven region woven with a double-woven structure is formed along a tape longitudinal direction. An inner single-woven region and an outer single-woven region of the single-woven structure are formed at a tape inner edge side and a tape outer edge side of the double-woven region. Thus, even if the fastener tape makes contact with ridge line portions on a lower blade side of the slider when the slider is slid, weft yarns arranged in the double-woven region are less likely to be cut.

A lower stop assembly for slide fasteners comprises a left stop member and a right stop member. The inside of the right stop member is provided with a right slot and an annular orifice both extending in the direction of the inside, the annular orifice being located at the front end of the right slot and in direct communication with an opening of the right slot. The left stop member can be movably inserted into the opening of the right slot and then released from lateral notches of the right slot. As the left stop member can be released from the lateral notches of the right slot, when the left stop member needs to retreat from the right slot, the left stop member may rotate around the outer lateral wall of the annular orifice under the drive of the left slide fastener belt to come out from the right slot.
