The clamping roller for a belt webbing clamping device consists of two identical plastic mouldings and a rolled steel sleeve inserted into a recess thereof. Said steel sleeve surrounds a pivot bearing pin of steel inserted into a bore of the plastic mouldings. This pivot bearing pin and the rolled steel sleeve bear on each other along a zone parallel to the axis of the clamping roller and form a composite member of high strength. |
