The invention discloses a transmission chain of a wind turbine generator and the wind turbine generator including the transmission chain, and belongs to the field of wind turbine generators. The transmission chain comprises a main shaft, a gearbox and a generator, all of which are connected in sequence. A bearing and a bearing pedestal mounted in cooperation with the bearing are mounted on the main shaft. A through hole is formed in the middle of the generator. An output shaft of the gearbox penetrates through the generator through the through hole and is connected with a generator rotor through a reverse flexible device. In the transmission chain, reverse shaft penetrating connecting is adopted between an output shaft of the gearbox and the generator rotor, that is, the output shaft and the generator rotor are connected through the reverse flexible device, the length of the transmission chain can be effectively reduced, and therefore the length of a rack and other relevant structure parts is reduced, and cos
