Abstract: A retractable wheel mechanism of a suitcase has a main housing, a retractable handle mounted in the main housing, two slidable panels mounted separately in the main housing, and two wheel sets separately mounted in the main housing. By extending or shortening the retractable handle, the slidable panels are driven to slide transversely and drive the wheel sets to protrude out of the main housing or to be retracted in the main housing. An owner of the suitcase can retract the wheel sets whenever he has to carry the suitcase without dirty his clothes, or whenever he has to pull the suitcase into an office or a room without revealing the dirty wheel. Moreover, an appearance of the suitcase becomes compact when the wheel sets are retracted.
