ABSTRACT:
A swivel castor comprises a pair of wheels (17) inclined inwardly to the upstanding swivel axis (11), such that the bottom of the wheels are spaced apart further than the tops. The swivel axis is offset forwardly of the wheel rotational axes. The arrangement gives improved support capacity and swivellability.
