PROBLEM TO BE SOLVED: To provide vibrating table apparatus in which, even if the frequencies of vibration of a load placed on a table body and of the table body are changed, the amplitude of the vibration of the table body can be made constant. SOLUTION: The hydraulic vibrating table apparatus is equipped with: a plurality of first hydraulic cylinders 2 mounted on a stand 1 at required intervals in a horizontal direction so as to face the up and down direction; a table body 3 disposed so as to hang across the upper ends of the plurality of first hydraulic cylinders 2; a second hydraulic cylinder 6 for supplying pressure oil causing the plurality of first hydraulic cylinders 2 to perform flexible operation at high speed, the pressure oil release/recovery ports of the second hydraulic cylinder 6 being connected in a communicated manner to the pressure oil supply/discharge ports of the plurality of first hydraulic cylinders 2 via piping 4, 5, respectively; and a driving motor 7 connected to the distal end of a rod in the second hydraulic cylinder 6 and reciprocating the second hydraulic cylinder 6 at high speed.
