Abstract
A novel and improved slider with a yoke for a slide fastener and a novel and improved method for attaching or joining the yoke to the slider body, which may be carried out in simple operation to be attractive in appearance and to provide firm combination between the yoke and the slider body. The front and rear support posts the slider body are respectively provided with locking groove and the contact faces of the yoke are also provided with bulged portions opposite to the locking grooves. In a preferred embodiment, after the support posts are covered with the yoke, a press force is applied to the bulged portion in the forging process to flow the material of the bulged portion into the locking groove so as to provide the firm combination. In the other preferred embodiment, after the yoke is covered on the support posts and is pressed in the deeply covering direction, a part of each support post is deformed by plastic flow to form a bulged portion in the locking groove of the yoke so as to combine the yoke with the support posts.
