PROBLEM TO BE SOLVED: To provide a collapsible supporting structure capable of supporting a cargo and being easily carried. SOLUTION: The collapsible supporting structure comprises a mounting body, an arm extending upwardly from the mounting body, and a front supporting leg and a rear supporting leg with a wheel. At least some of the front supporting leg, the rear supporting leg, and the arm are mounted on the mounting body so as to be turned around the mounting body with the crossing axis as a center, and turnable between the operable mode and the collapsed mode. In the collapsed mode, the front supporting leg, the rear supporting leg, and the arm extend substantially in the same direction. The arm takes the extending mode for the use and the contracted mode in which the total length of the arm is contracted. In the contracted mode, the total length of the arm becomes close to either total length of the supporting leg or the rear supporting leg. COPYRIGHT: (C)2007,JPO&INPIT
