PROBLEM TO BE SOLVED: To provide a device formed that a plurality of water turbines individually independently coupled are simultaneously rotated by using hydraulic energy and applying a difference between the internal and external pressures of a tank and though the number of revolutions per one set is decreased, the integrated number of revolutions is increased and generating efficiency is increased, and to provide a coupled water turbine type hydraulic generating device, a coupling type water turbine used in the device and a water turbine incorporating type tank used therein. SOLUTION: This invention comprises constitution that various system water turbines are incorporated, an air injector is set, a plurality of tanks having an inlet and an outlet are internally connected for coupling, and a water turbine is set in correspondence to a rear end tank outlet; constitution that a reaction type or a pump inversion type water turbine is incorporated, a tank having an inlet and an outlet is internally connected for coupling, and a water turbine is set in correspondence to a rear end tank outlet, and constitution that reaction type or pump inversion type water turbines are arranged with a distance therebetween, and a tank is internally connected between water turbines.
