FIXING DEVICE OF INTERMEDIATE MOVABLE BODY OF POOL

PROBLEM TO BE SOLVED: To simplify a fixing device of an intermediate movable body and bring out the stable fixing function, in a pool provided with the intermediate movable body which can vertically move and partition the pool. SOLUTION: Both longitudinal end faces of an intermediate vertically movable body are fixed to the side walls of a pool at the raised position. Recesses 30 in which a pair of vertical fixing pins 31 are erected, are formed at the side walls of the pool and a pair of holding arms 26 opening/closing in double swinging motion are rotatably provided at the longitudinal ends of the intermediate movable body. Both holding arms 26 are connected to a cylinder device 25 for the arm drive used in common through the interlocking motion. Both holding arms 26 are closed by the extension or contraction of the cylinder device 25 for the arm drive and both fixing pins 31 are held to the thickness direction of the intermediate movable body by the cam faces 32 thereof and locked so as to be pressed to the intermediate movable body side.
