PROBLEM TO BE SOLVED: To provide a support device of a swimming pool floor including a support leg mounted to be freely raised and laid down on a pool floor installed in a pool to be freely elevated, facilitating switching to a non-working position or a working position by raising and throwing down the support leg and preventing the support leg from being carelessly switched to the vertical state when the support leg is to be thrown down and laid along the pool floor. SOLUTION: The support leg 16 is mounted to be raised and laid down by the hinges 17 on the lower side of the pool floor 9, and a float 18 is fitted with the support leg 16 to energize the support leg 16 in the direction of falling. In raising the support leg 16, a tool is used which is engaged with the support leg 16 through a working hole of the pool floor 9 and pressed down until it abuts on a stopper 19 of the pool floor 9 against the action of buoyancy of the float 18.
