PROBLEM TO BE SOLVED: To provide a wind power generation device capable of keeping a function of a one-way clutch by taking a countermeasure to salt damage and the like on the one-way clutch connecting an output shaft of a speed-increasing gear and an input shaft of a power generator.SOLUTION: A wind power generation device includes: an input rotary body 5 integrally rotatably disposed on an output shaft 35 of a speed-increasing gear 3 in a power generation device 1; an output rotary body 6 integrally rotatably disposed on an input shaft 41 of a power generator 4; and concentrically mounted on a radial inner side or a radial outer side of the input rotary body 5; a one-way clutch 7 disposed between the input rotary body 5 and the output rotary body 6, integrally rotatably connecting the input rotary body 5 and the output rotary body 6 in a state that a rotating speed of the input rotary body 5 is higher than a rotating speed of the output rotary body 6, and disconnecting the input rotary body 5 and the output rotary body 6 in a state that the rotating speed of the input rotary body 5 is lower than the rotating speed of the output rotary body 6; and shielding means 92 for shielding a region where the one-way clutch 7 is disposed, from a space in a casing 18 accommodating the speed-increasing gear 3 and the power generator 4. |
