A wind power generator dispensing with a large diameter gear in a yaw driver (30) of a yaw system (10A). The yaw driver (30) of the yaw system (10A) for turning a nacelle (3) depending on the wind direction includes an electric motor (31) fixed on a nacelle base (12) having an output shaft (31a) approximately aligned with a turning axis of the nacelle (3). A gap between the output shaft (31a) and a fixed-side supporting member (2b) provided in the vicinity of the upper end of a column (2) are coupled via a coupling shaft (33) equipped with couplings (32) at both ends. |
