ABSTRACT:
A slider for a slide fastener with an automatic locking mechanism comprises a small number of components and hence can be assembled and operated with ease. A slider body of the slider has a receiving hole for receiving a resilient plate running in parallel with a guide groove and arranged in the upper wing plate of the slider body. The receiving hole has an enlarged open section arranged at the side of a rear opening and communicating with the guide groove to a claw receiving hole, and is formed to have a narrow tubular shape above a guide post. A wide groove is arranged along a lateral side of the receiving hole with a gap therebetween. A through hole is arranged to perpendicularly cross the receiving hole at the middle thereof. The resilient plate is introduced into the receiving hole from the U-shaped spring side for mutual engagement and the actuating portion of the operating member is introduced into the through hole until the cam surface resiliently abuts the actuated portion of the resilient plate and the spring plates extending from the operating portion exposed from the upper wing plate are arranged in the wide groove so that the operating member is held in place and resiliently movable back and forth. As the operating portion is operated, the cam surface raises the resilient plate and hence the locking claw to allow the slider to slide.
