A lock slider for a slide fastener, comprises: a slider body composed of upper and lower wings joined at their front ends, the upper wing having on its lower surface a pair of downwardly projecting side flanges and on its upper surface a pair of upwardly projecting lugs disposed with a width of a pull tab, each of the lugs having a horizontal slot and a pivot insertion hole communicating with the horizontal slot, the upper wing also having at least one locking-pawl insertion hole communicating with one of the horizontal slots; the pull tab having at its base a pair of lateral pivots to be inserted in the respective pivot insertion holes. Further, the pull tab has on one surface at least one locking pawl insertable through the locking-pawl insertion hole when the pull tab is pivotally moved about the base to lie flat on the upper surface of the upper wing. In production, the slider body and the pull tab are simultaneously molded in an assembled form using cores movable from the front, rear, right, left, upper and lower sides. |
