  • Patent number: 10869525
    Abstract: A slider for a slide fastener includes a body, a pull-tab, a control claw, and a cover. The control claw is placed on a shaft portion between a front attachment column and a rear attachment column. A protrusion length of a claw portion that enters an element path from a claw hole changes depending on an up-down position of the shaft portion so as to control movement of the body. The cover is attached to the front attachment column and the rear attachment column so as to be swingable in an up-down direction. The upper plate portion pushes the control claw downward due to a restoring force of a plate spring portion extending from a front end of the upper plate portion along a front surface of the front attachment column. The body, the pull-tab, the control claw, and the cover are separate components.
