Abstract
In a die-casting slide fastener slider having a plastically deformable, cantilevered pull-tab attaching lug on a slider body, the lug projects from an upper end of a guide post over an upper wing toward a rear end of the upper wing and terminates in a downward end projection spaced from the upper wing by a gap through which an attachment ring of a pull tab is threaded. The lug has a longitudinal hollow through its base to facilitate plastically deforming the lug to reduce the size of the gap after threading. In this structure, since first and second slide cores of a mold for die-casting the slide fastener slider can be inserted from the front and rear sides, it is possible to mold the lug without generating any parting line on its overall appearance.
