Abstract
A wheeled support structure for use in a vacuum cleaner or the like. The wheeled support structure includes a wheel mount on the body of the vacuum cleaner defining an outwardly opening recess having an inwardly facing lock surface. The wheel mount further defines a fixed annular bearing surface coaxially of the recess and spaced radially outwardly therefrom for journaling the wheeled support slidably concentrically mounted thereon. The wheel further includes a latch element extending inwardly through the recess and having turned latch shoulders arranged to be disposed inwardly of the lock surface for preventing axially outward removal of the latch element, thereby maintaining the wheel mounting surface slidably mounted on the bearing surface of the vacuum cleaner support wall.
