A vehicle having a steerable wheel has a mechanism for retracting the wheel into a compartment in the vehicle.The mechanism comprises a pillar 23 mounted to the vehicle within the compartment at two spaced positions, preferably at the top and bottom of the pillar.A steering arm 26 fixed to the pillar is movable to rotate the pillar 23 about its own axis. A collar 22 is slidably mounted on the pillar 23 but rotatable with the pillar. The collar 22 carries wheel forks 21 on which a pair of wheels is mounted on stub axles. The wheels are turned by rotation of the collar as a result of the steering action on the pillar, and their height is altered by raising and lowering the position of the collar on the pillar. The mechanism is applicable for use in an amphibious craft.
