Abstract
A foldable suitcase has an upper shell and a retractable support secured to the suitcase for supporting the suitcase at a working position and a folded position. The support is pivotally secured to the suitcase for allowing the support to be folded between an upright position and a lay down position and to be folded toward the suitcase to a compact folding structure. A handle may be fixed to the upper shell or may be extended outward of the upper shell for carrying the suitcase. The support may be folded relative to the suitcase by the actuation of the handle.
