A roller assembly or caster for an article of luggage has a casing or housing set into the bottom wall of the article and a stirrup affixed to an upper wall of that housing in which a roller is rotatable. The roller projects through an opening in a generally spherical convex cover and projects in part beyond this cover so that the cover will limit impact of obstructions against the stirrup and roller and will shield the interior of the housing from the incursion of foreign materials. The convex cover is affixed to the stirrup and, when the latter can swivel, swivels together therewith.
