A horizontal-axis wind turbine includes a rotor having a hub and blades rotatable by wind; a nacelle assembly for rotatably supporting the rotor through a main shaft, the main shaft being connected to the rotor; a tower for rotatably supporting the nacelle assembly; a dynamo placed near to a location at which the tower is built up; a rotatable vertical shaft orthogonally disposed to the main shaft inside the tower for transferring a rotating force of the main shaft to the dynamo; and a reaction torque-balancing mechanism for transferring a rotating force of the nacelle assembly, the rotating force of the nacelle assembly being derived from reaction torque due to a load of the dynamo, to the vertical shaft in a direction in which the reaction torque is balanced. |
