That is, 101 is a windmill attached to the top 102' of a windmill base 102 via a bearing 103, and the rotational power of this windmill 101 is transmitted to a generator 106 via a bevel gear 104 and a vertical shaft 106.

Since it is a so-called mechanical method using the vertical shaft 105, there is a drawback that the rotational friction force is large and the efficiency of power transmission is poor. Furthermore, the higher the height of the wind turbine base 102, the longer the length of the vertical shaft 106, which has the disadvantage that the structure of the wind turbine base 102, including its supporting method, becomes complicated.

。In the above configuration, when the windmill 1 rotates, the oil pump 2 is driven via the rotating shaft 3, and the high-pressure oil produced thereby flows through the hydraulic hose 1o as shown by the arrow at the rotary joint 70 and the fixed part 9. The oil then flows through the hydraulic hose 14 as shown by the arrow and is fed to the hydraulic motor 13. When the hydraulic motor 13 is driven by this pressure oil, the load generator 16 is rotated via the rotating shaft 16, and thus the rotating power of the wind turbine 10 is transmitted to the rotating power of the generator 160. The oil that has passed through the hydraulic motor 13 is transferred to the hydraulic hose 141, the fixed part 92 of the rotary joint 7, and the rotating part 8. It flows through the hydraulic hose 10' as shown by the arrow and is returned to the oil pump 2 again. Note that the oil supply device 11 serves to supply the oil pump 2 with the required oil.
