PROBLEM TO BE SOLVED: To provide a pool floor installed in a pool to be elevated, simplifying the structure of the elevating device for elevating the pool floor, and tilted or bent. SOLUTION: A pool floor 1a and a pool floor 1b constituting a pool floor 1 are collapsibly connected to each other by a hinge 12, and composed of a frame 14 formed of a closed square pipe and a hollow floor material. The pool floors are constituted so that the buoyancy exceeds the weight, and formed to have rigidity. The side wall of the pool floor is provided with a stopper projected to be stopped at the stage of the pool side wall, thereby positioning the elevating position. In the pool floor 1, wires 21, 22, 23, 24 are connected at fixed intervals to one side, the other side and both sides of the hinge, and bound together through a sheave 25 to be led to the outside of the pool, to draw and payout the wires by hydraulic cylinders 27, 28, 29, 30.
