PURPOSE: To obtain a multipurpose movable floor pool by standing a tabular movable floor having a plurality of air tanks on an underside and having a fluid path with a valve between upper and lower sections in the pool in a freely vertically inclinable adjustable manner. CONSTITUTION: A tabular movable floor 5 is stood in water and a large number of downward opening type air tanks 13 are installed to the lower section of the movable floor 5, projecting sections 13A are projected from the lower end sections of partition walls and the discontinuous escape of air is prevented while flowing water. When the movable floor 5 is lifted, each air tank 13 is supplied selectively with high-pressure air, and the air is elevated while changing the angles of inclination. When the movable floor 5 is lowered, on the other hand, each branch valve is controlled electrically and opened, and air is vented. The angle of inclination of the movable floor 5 is set within the range of±30 deg., and a plurality of auxiliary engaging mechanisms are mounted among a pool wall and both end sections or the peripheral section of the movable floor 5 in both end sections or the peripheral section of the movable floor 5. The movable floor 5 is fixed lightly onto the pool wall, thus preventing the tilting and vertical movement of the movable floor 5 due to the change of load, the movement of the center of gravity, etc.
