A slide fastener includes a bottom end stop member for limiting the downward or opening movement of a slider along a pair of series of fastener elements carried on and along confronting longitudinal edges of oppositely disposed stringer tapes. Each of upper and lower wings of the slider has a pair of guide flanges extending on and along its lateral edges. The lengths of each pair of guide flanges are so related to the pitch of the fastener elements that those two opposed fastener elements, located within a guide channel of the slider in adjacent relationship to the front ends of the two pairs of guide flanges, have their respective longitudinal axes disposed downwardly of the front ends of the lateral guide flanges when the slider is in its lowermost position. |
