A moveable article of luggage includes a closeable article-receiving interior compartment, a bottom wall, at least one free-spinning rear wheel attached to the bottom wall, the front wheels at a fixed distance apart, and a pull-type handle device. The retaining and pivoting assembly provides for unitary and concurrent pivoting of the front wheels about a forward pivoting axis and is pivotally secured to the bottom wall of the luggage article at the forward pivoting axis. The handle device is attached to the retaining and pivoting assembly for distributing and translating the forces required for moving the luggage along an underlying support surface and for changing the direction of rolling travel of the luggage by arcuately pivoting the retaining and pivoting assembly in a direct and unitary manner. In one embodiment, the retaining and pivoting assembly includes a tubular sleeve through which a common axle, on which the two front wheels are carried, is journalled. In another embodiment, the retaining and pivoting assembly includes a common member or plate to which separate front wheels are mounted.
