Wave power generation device including wire

A wave power generation device comprising:

• a buoy floating on the sea;
• a power generator generating electrical energy or hydraulic energy;
• a power transmitter connecting the buoy and the power generator to each other;
• and
• a wire connected to the buoy or the power transmitter and changing in tension by motions of the buoy;
• wherein the tension of the wire is input to the power generator through the power transmitter and a plurality of wires is connected to the buoy in different directions;
• the wire includes pluralities of first wires, second wires, and third wires that are connected to the buoy, and
• when a first axis, a second axis, and a third axis are defined as virtual rectangular coordinate axes that are perpendicular to one another, translational motion energy of the buoy on the first axis, translational motion energy of the buoy on the second axis, translational motion energy of the buoy on the third axis, rotational motion energy of the buoy about the first axis, rotational motion energy of the buoy about the second axis, and rotational motion energy of the buoy about the third axis are transmitted to the power transmitter through at least one of the first wires, the second wires, and the third wires.
