PROBLEM TO BE SOLVED: To provide a yawrotation drive device for a wind power generator capable of dispensing with a hydraulic braking device for fixing a wind power generating unit on an arbitrary swirling position, and applicable to the swirl driving of a large wind power generating unit. SOLUTION: In this yawrotation drive device of the wind power generator where the wind power generating unit 2 having a windmill 12 and a generator 23 rotated and driven by the windmill 12 is yawrotatably mounted on an upper part of a tower 1, the yawrotation driving of the wind power generating unit 2 is executed by two motors A and B. |
