The connecting member 20 includes a fixing part 21, a first spline part 22 and first pins 23. The fixing part 21 is fixed to the outer periphery of the main shaft 4 by means of the first pins 23 disposed along a circumferential direction of the main shaft 4. The first spline part 22 extending at other end of the fixing part 21 on a rear-end side, has a clearance S between the outer periphery of the main shaft 4 and the first spline part 22 and first spline teeth 24 formed on an inner periphery facing the clearance S. The clearance S opens at the end of the fixing part 21 on the rear-end side.

    摘要： A power generating apparatus of renewable energy type in which a hydraulic pipe between a hydraulic pump installed inside a nacelle and a hydraulic motor installed near a bottom part of a tower can handle the turning motion of the nacelle. In the power generating apparatus of renewable energy type, a hydraulic pump inside the nacelle and a hydraulic motor near a base end part of a tower are connected by a first double pipe and a second double pipe. The first double pipe is rotatably connected to the second double pipe. The first double pipe includes a first inner pipe and a first outer pipe. The second double pipe includes a second inner pipe and a second outer pipe. The first and second inner pipes communicate with each other to form an inner passage. The first and second outer pipes communicate with each other to form an outer passage.
