Claims (1)

[Claims for Utility Model Registration] (1) An extended position in which one edge is butted and connected via a hinge means so that it can be used, and a folded position in which the abutting edge is pushed up and the lower surfaces are brought into contact with each other. A pair of left and right decks that change into a flexing position, a central main leg that supports the abutting ends of both decks, and legs that are located below the outer edges of both decks and work together with the central main leg to support the deck. A stage device comprising left and right outer main legs equipped with wheels for movement at the ends, wherein both decks are provided with hinge pieces at abutting ends, and a connecting piece is provided between the hinge pieces. The hinge pieces are rotatably pivoted and connected via a connecting shaft, and the hinge pieces are provided with circular gear plates centered on the connecting shaft so as to mesh with each other, and the central main leg is connected to the upper end. The leg end is connected to the leg end of the left and right outer main legs via a connecting rod, and the outer main leg is opposed to the leg end. Fixed connecting rods that are slidably fitted to the deck and can be freely expanded and contracted are crossed in an intersecting manner, and each end is rotatably pivoted, and a tightening device provided in the middle of the connecting rod is tightened. Foldable stage equipment that restricts expansion and contraction. (2) In the statement in paragraph 1 of the claims for utility model registration, the structure is contracted so as to be constantly biased in the extension direction between the left and right decks and the mid-height of the outer main landing gear that supports the outer ends of the respective decks. A folding stage equipment characterized by having a biasing means inserted therein.
