Abstract
An object of the present invention is to provide a wind turbine generator and a tidal current generator equipped with a hydraulic transmission with a combination of a hydraulic pump and a hydraulic motor and which has a superior productivity and maintainability. The wind turbine generatorhas the hydraulic transmissionfor transmitting the rotation energy of a main shaftto a generator. The hydraulic transmissionincludes a hydraulic pumpof variable displacement type which is driven by the main shaft, a hydraulic motorof variable displacement type which is connected to the generator, and a high pressure oil line and a low pressure oil line which are arranged between the hydraulic pumpand the hydraulic motor. The hydraulic transmissionis at least partially constituted of a plurality of modules (Mto M).
