Abstract: One object is to promptly and accurately sense an abnormal state of a wind turbine driving device. The wind turbine driving device includes a driving device body and a sensor. The driving device body is installed in one structure at a movable section of a wind turbine. The driving device body includes a meshing portion meshing with a ring gear installed in the other structure at the movable section of the wind turbine. The sensor measures a change in installation state of the driving device body with respect to the one structure.

Abstract: Damage to a driving device or a ring gear or both due to an excessive force at a meshing portion therebetween is effectively prevented. In the embodiment described above, a driving device includes a driving device body that is provided in one structure at a movable section of a wind turbine and has a drive gear meshing with a ring gear provided in the other structure at the movable section, and an abnormality detection unit that monitors a force generated between the ring gear and the drive gear or the state of the driving device body or monitors both of the face and the state. Output from the drive gear of the driving device body to the ring gear is stopped when the abnormality detection unit detected an abnormality.
