PROBLEM TO BE SOLVED: To provide a wave-power generation device with a turbine rotating in the same one direction by a reciprocating flow of air, capable of maintaining a high degree of conversion efficiency even if its cycle or wind velocity varies, with its structure being of a simple one resulting in a small number of movable parts and components, thus its equipment cost being reduced and maintenance being made easy.SOLUTION: There is provided a wave-power generation device 10 that generates power by a turbine 14 installed in a duct 13 in communication with an air chamber 11 into which sea water W flows in and out, with a turbine 14 to be constituted of a variable pitch turbine 100 so constructed that its blade 120 is brought to rotate autonomously around a mounting angle change shaft 121 without performing an operation input, in response to the direction of the flow of air within the duct 13, air velocity, or rotational angular velocity of the turbine shaft 110. |
