Abstract: The traveling case with an erectly expanded case body consists of one case body, one adjustable shaft pair, one positioning and binding base and one wheel and foot base. The outer shaft of the adjustable shaft pair passes through the shaft installation hole on the positioning and binding base and gets fixed at the rear insdie the body. A stretchable and foldable mezzanine is installed on the body that expands horizontally against the moving direction of the adjustable shaft. That is, the zipper opens and closes vertically against the movement of the adjustable shaft. Therefore, when the above case body is stretched, the inner space is increased and the traveling case will not topple and fall, which enhances the steadiness of the traveling case.
