Abstract
A roller device of luggage case includes the luggage case having at least two retractile mechanisms with at least two rollers at each bottom side. The retractile mechanism is connected with retractable handle pivotally so that the rollers stick outside the bottom of the luggage case when the retractable handle is pulled up and completely hides within the luggage case while the retractable handle is folded up. Thus not only the luggage case has a better outlook but also the trouble of hooking with other luggage can be avoided.
