PROBLEM TO BE SOLVED: To easily assemble supports and straightly stand the supports with respect to a desk by forming vertical cylindrical parts on rear parts of left and right plate- shaped legs directing the longitudinal direction and supporting a top board, inserting the supports upwardly projecting from the top board, into the cylindrical parts, and placing and supporting lower ends of the supports on the bottom plates of the plate- shaped legs. SOLUTION: Vertical cylindrical parts are formed at the rear parts of the left and right plate-shaped legs supporting a top board, the supports 4 are inserted into the cylindrical parts, and lower ends of the supports are placed and supported by bottom plates of the plate-shaped legs. The cylindrical parts respectively have a structure capable of internally holding the supports 4 in the vertical direction, and controlling the hozirontal movement of the supports 4 at least at two points of the vertical direction. The cylindrical parts respectively consist of a rear rod 10 and a square support supporting frame fitted on an upper part of the rear rod 10. A rear surface 4a, a left side surface 4b, a right side surface 4c and a front surface 4d of the support 4 are respectively opposite to a rear surface 10b, a left side surface 10c and a right side surface 10d of the rear rod 10 and an inner surface of a flange 10a to regulate the horizontal movement and to hold the support 4 in the vertical direction.
