ABSTRACT:
In an automatic lock slider for a slide fastener, a yoke accommodating a locking pawl and a leaf spring has a pair of inwardly directed projections, and a generally C-shaped, narrow rigid strip has on its upper edges a pair of taper surfaces corresponding to the respective projections. As the taper surfaces are guided by the projections, the pawl keeps its suitable posture during the assembling of the slider, and the pawl acts reliably while the automatic locking mechanism is either operative or inoperative. The locking pawl is small in width and has one leg portion to be inserted in a groove of the outer surface of a connector of a slider body. The result is that the number of pressing steps is reduced to minimize press traces on the surface of an upper wing of the slider body so that press traces are prevented from coming out on the slider surface though the yoke is smaller in width compared to the conventional one.
