- 34 A wind turbine generator is provided with a generator which is provided with a stator and a stator casing accommodating a generator rotor and the stator; a main 5 shaft having one end coupled to a wind turbine rotor and the other end coupled to the generator rotor; a first bearing which rotatably supports the main shaft; a second bearing which is provided on the main shaft to support the stator casing such that the main shaft and the stator casing 10 are rotatable relative to each other; a base to which the first bearing is attached; and a torque support including a coupling member which couples the base portion and a front plate of the stator casing. The load center of force actJng between the coupling member and the front plate in 15 a case that torque acts on the stator casing in the circumferential direction of the main shaft is positioned i.n a range between the front and back surfaces of the front plate. |
