WIND-DRIVEN GENERATOR DEVICE

摘要

A wind turbine generator provided with a sliding bearing as a yawing ring bearing that can reduce shifting of an axial center by making radial-direction clearances small. In a wind turbine generator in which a nacelle (3) installed at the top of a tower (2) is turnably supported via a yawing sliding bearing (30), the yawing sliding bearing (30) is provided with a sliding member 33 disposed between top and bottom support surfaces of a flange formed mainly at a stationary portion (32) and a turning portion (31); and a rolling element (34) disposed between the stationary portion (32) of the yawing sliding bearing (30) and the turning portion (31).
