PROBLEM TO BE SOLVED: To provide a floating body structure for offshore wind power generation, which can suppress an exciting force generated by a wind power generator and reduce upward/downward oscillation caused by ocean waves.SOLUTION: A floating body structure for being used as a foundation of a wind power generator for offshore wind power generation includes: a taut mooring rope 14 for mooring the floating body structure by connecting the buoyancy center C of the floating body structure and an anchor to tension the floating body structure; an oscillation attenuation mechanism 16 that is interposed between the floating body structure and the taut mooring rope 14 to attenuate vertical oscillation of the floating body structure; and a natural frequency adjusting mechanism 42 for adjustment natural frequencies of a floating body and the mooring rope.SELECTED DRAWING: Figure 2
