<P>PROBLEM TO BE SOLVED: To provide a swimming pool having a highly safe movable wall, in which the movable wall can be surely supported at a rise position at a longitudinal intermediate location of the swimming pool. <P>SOLUTION: A movable wall body which is vertically movable from a swimming pool floor side in water-surface direction is provided, and a drive unit for reciprocally moving the movable wall body is installed. When the movable wall body is located at the lowermost descended position, it is stored in a swimming pool bottom part. The movable wall body is configured in such a manner that in the state where the movable wall body is stored, a top face of the movable wall body and a bottom surface of the swimming pool are integrated with each other so that the whole swimming pool bottom part is flat. A position where the drive unit supports the movable wall body is provided such that the position is above the center-of-gravity position of the movable wall body, and the drive unit is configured by combination of a drive motor and a screw jack. <P>COPYRIGHT: (C)2013,JPO&INPIT |
