PROBLEM TO BE SOLVED: To provide a movable-floor supporting device for movable-floor pool that can be reduced in construction cost, can be adopted even when no space is available under a movable- floor pool, can turn supports approximately at once between their supporting positions and stored positions, can stably support the movable floor of the pool, require no storehouse for the supports, and makes its maintenance easier. SOLUTION: This movable-floor supporting device 20 supports at a prescribed height the movable floor 15 which is provided above the bottom 11 of the main body 10 of the movable- floor pool 1 in which the space 13 surrounded by the bottom 11 and side walls 12 of the main body 10 is filled up with water and is moved upward and downward so as to change the depth of the water. The device 20 is constituted of the supports 21 which are turnably journaled by hinges 22 between their supporting positions P1 where the supports 21 are erected and stored positions where the supports 21 are folded at a plurality of supporting spots set on a movable-floor frame F and an actuating unit 25 which actuates the supports 21 between the supporting positions and stored positions and is composed of a take-up drum 27, a wire 26, and a pulley 28. Alternatively, the device 20 is constituted of the supports 21 and a driving unit 35 composed of a gear box 36, horizontal screw rod 37, nut 28 in which the rod 37 is screwed in, interlocking link 21 which links the supports 21 to each other, and drive link 29.
