Abstract
In an auto-lock slide fastener slider, an upper wing of a slider body has front and rear lugs on its upper surface, a through-hole under the front lug, a pair of locking-spring-supporting seats at opposite sides of the through-hole, a locking-pawl-insertion hole under the rear lug, and a cam-receiving recess between the lugs. A pull tab has a cam on an eccentric axle. A locking leaf spring has a streamlined central base, a front end portion at a front end of the base, a locking pawl at a rear end of the base, front and rear openings near the opposite ends of the base, and an oblique engaging strip projecting fra the front end of the base and engageable with the front lug. The spring is placed over the pull tab's cam, which is received in the cam-receiving recess of the upper wing, with the openings being threaded by the lugs and with the front end portion fixed to a guide post of the slider body.
