A wind turbine generator (1) is provided in which, even in a cold snowy environment in a cold region, the time required for recovering a frozen anemoscope/anemometer is reduced to minimize a decrease in operating ratio. A wind turbine generator is equipped with an anemoscope/anemometer (7) at the top of a nacelle (3) that accommodates a driving and generating mechanism connected to a rotor head (4) on which turbine blades (5) are mounted, wherein an in-nacelle cooling air outlet (12) that opens in the direction of the anemoscope/anemometer (7) is provided at the top of the nacelle, and the air outlet has exhaust flaps (13) serving as blowing-direction changing means for the cooling air. |
