Abstract
Provided is an underwater floating-type ocean current power generation device whereby cyclical directional vibration of a floating body of the ocean current power generation device, caused by shadow moment, can be suppressed. An underwater floating type ocean current power generation device includes ocean current power generation device main bodies, each including a rotor of a power generator housed in a nacelle, and a structure. The rotor is configured to be driven by a rotary blade protruding outward from the nacelle. A twin drum floating body capable of floating underwater is constituted by the structure and the ocean current power generation device main bodies joined to the left and right of the structure. The underwater floating type ocean current power generation device is moored to an ocean floor by a mooring rope.
