1. A joint structure used for a wind power generation device that generates power by rotating an input shaft of a power generator by a torque from an output shaft of a speed increaser, said joint structure comprising:
an output side transmission shaft which rotates integrally with the output shaft; an input side transmission shaft which rotates integrally with the input shaft; a fixed housing fixed to a structural object of a machine room where the speed increaser and the power generator are placed; a bearing which supports, by the fixed housing, the output side transmission shaft and the input side transmission shaft inserted in the fixed housing; and a one-way clutch which is fitted in the fixed housing, which integrally rotatably connects the output side transmission shaft and the input side transmission shaft, and which releases the connection, wherein the one-way clutch integrally rotatably connects the output side transmission shaft and the input side transmission shaft under a condition where a rotation speed of the output shaft is higher than a rotation speed of the input shaft, and releases the connection between the output side transmission shaft and the input side transmission shaft under a condition where the rotation speed of the output shaft is lower than the rotation speed of the input shaft. |
