ABSTRACT:
A slide fastener slider with an automatic lock mechanism comprises a body including a support lug standing on a guide post, a guide lug standing at a rear opening side of the body, a recessed portion defined between the support lug and the guide lug, a pair of projections project from opposite sides of the recessed portion. A spring is mounted to the body with its V-shaped bent portion of the spring fitted into the recessed portion. The bent portion is then fixed by caulking the projections. A pintle of a pull tab is disposed on the spring. A pawl member, which has an pressing portion to be brought into resilient contact with the spring on its one end, the locking paws on the other end, and a support shaft at opposite sides of an intermediate portion thereof, is disposed on the pintle. The support shaft is axially supported on the support lug, the locking pawl side at a rear end of the pawl member is guided by the guide pawl, and the locking pawl is allowed to pivotally move for being fitted into and detached from the fastener elements by operating the pull tab. In the slider with the automatic lock mechanism, therefore, the pawl member and the spring can be easily disposed and assembled, and the pivotal movement of the pawl member can be guided on the locking pawl side.
