Abstract
A bottom structure of a bag is disclosed. In the bottom structure, support rings are longitudinally arranged on the bottom thereof. Sleeve pipes fixedly fitted in the support rings such that the sleeve pipes longitudinally extend in parallel on the bottom of the bottom structure. A pair of bushings are fitted into the front wall of the bottom structure such that the bushings are aligned with the sleeve pipes. A pair of handle pipes are movably received in the bushings as well as in the sleeve pipes such that the handle pipes appear out of and disappear in the bushings as well as in the sleeve pipes. The rear end of each handle pipe has a stopper for preventing separation of the handle pipes from the bushings when fully extending the handle pipes out of the sleeve pipes. A plurality of rollers are mounted to the rear end of the bottom structure.
