PROBLEM TO BE SOLVED: To provide an elevating table device capable of being elevated and sunk by a motor remaining in a small size and of allowing the down-position of a load table to be as low as practicable. SOLUTION: An elevating table device is equipped with a load table 1, a horizontality maintaining means 3 of pantograph type, and a driving means 4 for elevation and sink. The driving means 4 comprises a drive arm 13 for elevation and sink, a feed screw mechanism 14 for the arm, and a drive motor 15 for elevation and sink. The arm 13 is structured so that one end is rotatable and the other end is movable in the horizontal direction. At the down-end, the arm 13 assumes an angle greater than the angle of a supporting arm 6 constituting the horizontality maintaining means 3 with respect to a horizontal plane.
