[Problem] To achieve an efficient, large-scale, high-output, and economical wave power generation system, and thereby achieve a method and structure for enabling a larger scale for providing a larger cross-sectional area or line length across which the flow of a wave is received. [Solution] A rotating disc equipped with a plurality of flow-receiving blades having passive variable pitches is arranged or floated in a horizontal direction in the vicinity of a water surface and rotated by providing thrust force from wave movement as an energy source, and energy is absorbed from the rotation. The plurality of flow-receiving blades are installed in sectioned positions, thereby making it possible to respond, in an independent and optimal form for every section, to a wave flow constantly changed by the influences of the movement direction, wavelength, cycle, and shape of the waves and by the influence of the other blades, and also thereby making it possible to respond optimally and in small increments to the complicated movement of the waves in a wide range across the entire device. Efficiency of wave energy absorption is thus also improved. Also, a larger scale is achieved by a simple structure.
