A foldable table−tennis table having right and left top boards that can be easily unfolded and folded, superior in the safety of operation, and adapted to be easily handled even by old people, children, the handicapped, etc. In the unfolded state in which top boards (1, 1’) are horizontally supported by support legs (5, 5’), gas dampers (7, 7’) are in their contracted state. When the top boards (1, 1’) are turned in the folding direction from this state, the gas dampers (7, 7’) are expanded to urge the turning of the two top boards, the urging force causing the two top boards to rise face to face while causing the support legs (5, 5’) to rise along the back surfaces of the top boards (1, 1’) to change to their folded state, so that the labor involved in the folding can be greatly reduced. When the two top boards (1, 1’) in their folded state are turned in the unfolding direction, the weights of the top boards contract the gas dampers (7, 7’) into their unfolded state. In this case, the elastic forces of the gas dampers support the weights of the top boards to buffer the loads, thus making it possible to greatly improve the safety of unfolding operation and to reduce the sound producing during unfolding.
