PROBLEM TO BE SOLVED: To provide a working floor which is good in assembling efficiency, smoothly moves in a manner striding an obstacle, and allows an underfloor portion thereof to be used as a storage area. SOLUTION: The working floor includes at least four supports arranged at longitudinal and lateral tip portions of a quadrangle, and each support is formed by connecting to each other a plurality of support forming bodies which are different in length. Each support has a large-diameter wheel attached to its lower end, which renders the support movable. Further, the support has a movable body fitted thereinto in a vertically movable manner, and a plurality of pin insertion holes into which pins for fixing the movable body to the support are inserted, are formed in the support forming body at suitable longitudinal intervals. Then, the movable bodies longitudinally and laterally adjacent to each other are connected together by beams to constitute a floor frame. Furthermore, the floor is mounted on the floor frame, and an elevating means for vertically elevating the movable bodies is provided for the working floor.
