The castor wheel (3) mounting, particularly for a shopping trolley, comprises a forked wheel carrier (9) swivellable on a bush (10). This is secured to longitudinal horizontal members (4,5) of the undercarriage (1) by a bolt (11) and two clamp elements (12; 13,14,14'). These elements are L-shaped (13,14) and each have the end (14') of one side (14) bent for engagement with a member (4,5), whilst the end of the other side (13) may be similarly bent and recessed (16) to engage the bolt. The upper element may have a bush fixed to it and provided with internal screw thread for the screwed upper end of the bolt. |
