A turntable element comprises a substantially flat bearing member holder (16) and a plurality of bearing members (26) which are rotatably engaged in respective apertures (24) extending inwardly towards the centre of rotation of the turntable element from the outer edge of the holder (16). The bearing members are retained in their apertures by portions (30) which engage the inner edge of the holder. The element may be formed as an integral plastics body wherein the bearing members are forcibly displaced so as to break frangible webs and bring the members into rotatable engagement with the holder. <IMAGE> |
