The object of the invention is to provide a wind power generator whose yaw bearing can be replaced by a simple device. A wind power generator (1) has a nacelle (20), a tower (30) that supports the nacelle (20) at a high location, a yaw bearing (40) that is located between a first bearing seat that is provided on the bottom section of the nacelle (20) and a second bearing seat that is provided on the top section of the tower (30), first and second jack seats (32) that extend to the outer diameter side of the first and second bearing seats, a jack-up (100) unit that is located between the first and second jack seats (32) so that there is a space though which the yaw bearing (40) can be removed or installed in the radial direction of the yaw bearing (40), and that can jack up the nacelle (20), and a suspension unit (50) that is provided on the nacelle (20) and that can move while suspending the yaw bearing (40). |
