A castor wheel assembly comprises a tubular casing of rectangular cross section extending in axial direction between a pair of opposed ends and a swivel member for connecting the casing to an object supported thereon for relative rotation about a vertical swivel axis. A shaft extends horizontally through the casing for connection to pivot arms at opposed ends thereof. A castor wheel is coupled between the pivot arms spaced radially outwardly from the shaft. A flange spans radially from the shaft a fully width of the casing along a length of the shaft. Elastomeric material supports the shaft and the flange along one wall of the casing such that the elastomeric material is arranged to be compressed between the flange and an opposing wall of the casing by rotation of the shaft resulting from upward deflection of the wheel relative to the casing.
