Abstract: A folding billiard table includes a billard table face, and a frame member supporting the billiard table face, a pair of main support legs rotatably mounted on eccentric portions of the frame member. A pair of foldable lateral support legs is disposed on one side of the main support legs, a pair of liftable and foldable lateral support legs is disposed on other side of the main support legs, and a pair of long and short linkages are disposed between the main support legs and liftable and foldable lateral support legs. When it is not used, the billiard table face can be turned upward, with the liftable and foldable lateral support legs raised, so that the billiard table face can be turned from a horizontal position to a vertical position to reduce the room occupied by the table.
