Abstract
A caster wheel device for a domestic appliance is in the form of a wheel mounting carriage, a dial having an underside forming a cam, a cam follower that contacts the cam, a wheel bracket and a wheel. The wheel bracket retains the wheel within it so that the wheel and bracket pivot about the follower independently of the carriage. The cam follower is attached to the wheel bracket and the wheel is able to trail behind the cam follower to form a trailing wheel caster when lowered.
