PROBLEM TO BE SOLVED: To provide a bracket for a working floor which can be folded up at a position where it is not a hindrance, while it is left fitted to a building frame, on the occasion when it is not used. SOLUTION: The base end part of a horizontal material 4 is fitted pivotally to the upper end part of a vertical material 3, while the opposite end parts of an extensible-contractible diagonal material 5 are fitted pivotally respectively to the lower end part of the vertical material 3 and the fore end part of the horizontal material 4, and clamps 6 which can be fixed to a prefabricated scaffolding or a building frame 2 are fitted to both the upper and lower end parts on the back side of the vertical material 3. The horizontal material 4 is held at a horizontal position by the diagonal material 5 and the vertical material 3 in a state wherein the diagonal material 5 does not contract any more, and by extending the diagonal material 5 from this state of contraction, the diagonal material 5 can be folded up in parallel to the vertical material 3, together with the horizontal material 4.
