This waterproof slide fastener (1, 2, 3, 4) is configured so that first and second through-holes (14a, 14b) are formed at specific intervals in tape side edges of waterproof tapes (11), and so that first and second halves (15, 16) of fastener elements (12) are connected and integrated together through the first through-holes (14a). A stopper (20, 30, 40, 50, 60) has a body section (21, 31, 41, 51, 61) and an extension section (22, 32, 42, 52, 62) which extends from the body section (21, 31, 41, 51, 61). First and second halves (23, 24) of the stopper (20, 30, 40, 50, 60) are disposed so as to straddle the pair of waterproof tapes (11) and are connected and integrated together through the second through-holes (14b). As a result of this configuration, the manufacturing step of the waterproof slide fastener (1, 2, 3, 4) is simplified, and water is prevented from entering even if the slide fastener (1, 2, 3, 4) is subjected to a lateral pulling force. |

1. A waterproof slide fastener including:
a pair of fastener stringers in which a plurality of synthetic resin fastener elements is injection molded on opposed tape side edge portions of a pair of waterproof tapes provided at least one of tape surfaces with a waterproof layer; a slider slidably attached to an element row including the plurality of fastener elements; and a synthetic resin stopper placed on at least one of ends of the element row, in which the fastener elements includes a first element half placed on a first tape surface side of the waterproof tape and a second element half placed on a second tape surface side of the waterproof tape, and the first and second element halves are integrally connected to each other through first through-holes which are drilled in the tape side edge portion at predetermined intervals from each other, wherein each of the waterproof tapes includes at least one second through-hole drilled in a forming region of the stopper at the same intervals as those of the first through-holes, the stopper includes a body portion with which the slider comes into contact to stop the slider, and an extension portion extending from the body portion in a direction opposite from the element row along a tape length direction, the body portion and the extension portion are integrally molded each other by injection molding, a first half placed on the first tape surface side and a second half placed on the second tape surface side in the body portion and the extension portion are fixed such that the first half and the second half straddle the pair of waterproof tapes, and the first half and the second half are integrally connected to each other through the second through-hole. |
