A castor fork (1) which supports a wheel (2) is formed from two discrete parts (9, 10). Each part (9, 10) has a leg portion (3) and a body portion (5). The two parts (9, 10) are clamped together by means of screws or bolts (12, 13) and receive a bearing race (11) to which is attached a support member (6) of an article to which the wheel (2) is to be attached. The castor fork (1) thus constructed is stronger than known assemblies and can be assembled and dismantled more quickly, easily and accurately. The arrangement allows recesses and spigots to be precast into the parts and tailored to the particular castor, for example to accurately locate multiple bearing races, wheel bosses and brakes. |
