WHEEL CONSTRUCTION FOR VACUUM CLEANER Abstract of the Disclosure A wheel assembly for a vacuum cleaner includes an axle, a collar, and a wheel. The axle is cylindrical and has inward and outward ends. The inward end is attached to a housing of an associated vacuum cleaner and the outward end has locking projections extending radially outwardly from an axial centerline. The collar has an outward end which includes collar gaps. When the axle is fitted within the collar, the locking projections fit into the collar gaps preventing rotational movement between the collar and the axle. The wheel has a wheel bore therethrough. When the wheel is fitted over the collar and axle, so that the collar and axle fit within the wheel bore, the locking projections snap radially outwardly against an outer surface of the wheel, thereby holding the wheel, collar, and axle together and permitting rotational movement between the wheel and the collar.
