ABSTRACT:
A slide fastener slider comprises a pair of upper and lower wings joined integrally together at its front end by a diamond; and a pair of flanges disposed between the upper and lower wings and converged towards the rear end of the slider to thus define with the diamond a Y-shaped guide channel for running of fastener element rows therethrough. The slider further includes a plurality of large-diametered guide rollers rotatably mounted thereon for rolling engagement with the fastener element rows. The slider is specifically constructed such that there remain open spaces around the guide rollers, so that stringer tapes is quite immune from being stuck in the guide rollers.
