The free access floor includes a plurality of panel support structures, each being formed of a square shaped frame where each of four sides of the frame is formed of a plate member, support units provided at two corners of the square shaped frame for supporting a free access floor panel, and grooves provided on a bottom surface of the support unit where corners of another panel support structure fit in the grooves.
