Abstract

In a multi-part plastic cage having a comb part with a plurality of axially extending webs adapted to engage a cover part, the cover part has recesses for receiving the ends of the webs, to absorb radial forces. The parts are joined by pins extending from one of the elements into recesses in the other, adapted to be joined by ultrasonic welding at positions spaced from the web ends, so that the pins are subject only to axial loading.
