A retractable roller assembly for luggage and the like which has a casing adapted to be secured to the luggage having an elongated opening on a lower edge. The side walls of the casing have a pair of aligned circular sockets which fittedly and rotatably receive circular cheek-plates of a bifurcated yoke. A roller is mounted between the cheek-plates for rotation about an axis eccentric to the axis of rotation of the cheek-plates so that the roller can be moved between a hidden position entirely within the casing and an operative position extending from the casing, by rotatably adjusting the yoke.
