A castor 1 with swivel direction lock for a walking support apparatus comprises a wheel 3 coupled to a lower part 13 of a castor body which swivels relative to the upper castor part 11. A swivel direction lock 7 configured to allow swivelling motion in a first position and inhibit the swivelling motion in a second position comprises a resiliently biased locking pin 15 retained in the lower castor body 13 and receivable in each of a plurality of spaced apart apertures 17 in the upper castor body 11 to lock the direction of the castor wheel 3. The swivel locking pin 15 is actuated by a movable switch 9 having a sleeve 8 which receives the pin 15 and engages a lateral protrusion 10 at an end of the pin to restrict movement of the pin within the sleeve.
