PROBLEM TO BE SOLVED: To provide stairs for temporary scaffold, even if the installation space for the stairs for temporary scaffold is narrow. SOLUTION: A plurality of lateral pipes 13 to 20 are erected at the prescribed positions between outer peripheral supports 12A to 12H and center support 11 where a plurality of grouped linking fittings 27 to 31 are provided, and around the center supports 11, a plurality of stair units 21 to 24 are hooked spirally continuously to the lateral pipes 13 to 20 at the prescribed positions. Thus, the stair units 21 to 24 are drawn with the minimum radius, and a space for installing the stair can be reduced surely.
