Abstract
A pod of an ocean current power generation device which is serving as an underwater floating-type underwater device is provided with a ballast tank and an air storage tank. When discharging water from the ballast tank, by opening a water discharge valve and driving a water discharge pump, water inside the ballast tank is discharged to the outside through a water conduit. When supplying water, by opening a water supply valve while the water pressure outside the pod is greater than the water pressure inside the ballast tank, water is made to flow from the outside of the pod through an aperture portion, and into the ballast tank via the water conduit.
