An arrangement for supporting a wheel for rotation about an axis comprises a wheel carrier part 13 having an at least partially annular carrier formation 16 extending therefrom generally in the direction of the axis, a wheel 18 encircling at least part of the carrier formation 16 and a retaining member (20, fig 1) releasably engaging the carrier part 13 and affording a bearing surface with which a complementary bearing surface of the wheel 18 co-operates to support the wheel 18 for said rotation. The carrier formation 16 and the wheel 18 preferably snap fit with one another and the retaining member (20, fig 1) includes a bayonet type arrangement for fitting with the carrier part 13. The wheel-supporting arrangement is preferably for a domestic appliance such as a vacuum cleaner and a filter (22, fig 1) may be housed in the wheel 18. |
