The wheel-mounting member has at least one formation for supporting an axle of the wheel.

Abstract: An improved wheel assembly comprises a caster fork, a caster wheel rotatably supported by the caster fork, and a caster swivel post defining an axis about which the caster fork rotates. The caster swivel post is being adapted to rotate about a pivot axis within a cylindrical housing. Alternatively, the wheel assembly has an adjustable axle for varying the camber angle of a wheel. The wheel assembly comprises a housing and an axle supported by the housing. The axle in turn rotatably supports a wheel. The axle is adapted to rotate about a pivot axis within a cylindrical housing.
