Abstract
In a slide structure employing balls comprising an outer element formed by a U-section element 1 provided with flanges 2, the inner element 8 is constituted by a tube which is deformed in such manner as to include two lateral wings 10 each one of which is between two concave grooves for receiving the balls 16. Beyond the portion of the tube deformed in this way, the tube is bent and devoid of flanges so as to enable it to extend through the opening 3 of the U-section element 1 before resuming its initial section. The tube terminates in fixing tabs. Sheared and deformed portions which are evenly spaced apart along a central longitudinally extending boss 18 of the inner element constitute a rack for driving or locking the inner element relative to the outer element.
