PROBLEM TO BE SOLVED: To provide a renewable energy type power generating apparatus in which weight of a nacelle can be reduced.SOLUTION: The regenerative energy type power generating apparatus comprises at least one blade; a hub 6 to which the blade is mounted; a hydraulic pump 8 driven by the hub; a hydraulic motor 14 driven by pressure oil fed from the hydraulic pump; a power generator driven by the hydraulic motor; a nacell base plate 10A that has a front wall in which a through-hole through which the hub penetrates is formed and that supports the hub; and a main bearing 18 which is provided in the through-pass hole and allows the hub to rotate in respect to the nacell base plate. The hydraulic pump includes a pump rotor 20 connected to the hub, and a pump stator 22 provided in an outer circumferential part of the pump rotor, fixed to a wall surface far from the hub and supported by the nacell base plate, and the pump rotor is allowed to rotate in respect to the pump stator by the main bearing. |
