PROBLEM TO BE SOLVED: To provide a support device for a floating body of floating body type ocean wind power generation equipment for swingably supporting an assembly such as a wind mill mounted on the floating body and a water wheel which is installed under water level and is driven by tidal power.SOLUTION: Six brackets 43 are fastened to an inner wall 42 of a hollow 41 of a floating body 4, and six elastic support parts 6 are attached between an attachment surface 431 of the bracket 43 and an outer circumferential surface 521 of a lower part bearing support body 52. The six elastic support parts 6 are arranged at uniform angular intervals around a center axial line 11 of a first driving shaft 21 and a second driving shaft 31. The elastic support parts 6 are formed by stacking rubber and a metal plate alternately. As the result, the elastic support parts 6 support a load which acts on a bearing support body 5, follow relative movement between the bearing support body 5 and the floating body 4 to perform shear deformation and absorb vibration energy of winds or waves acting between the bearing support body 5 and the floating body 4 to attenuate vibrations. |
