PROBLEM TO BE SOLVED: To provide a scaffold unit having a simple scaffold board structure which can be easily installed between two sides nonparallel to each other of structural elements each having a triangular or trapezoidal planar shape with their separation distance made variable. SOLUTION: A scaffold unit A1 is installed between two sides of structural elements each having a nonparallel triangular or trapezoidal plan shape and comprises a scaffold board 1 and slide members 2 located at the ends of the scaffold board 1 in its longitudinal direction. Each slide member 2 has an opening 2a receiving an end of the scaffold board 1 in the longitudinal direction, and the opening 2a is so formed as to make the length of insertion of the scaffold board 1 adjustable.
