PROBLEM TO BE SOLVED: To provide a wind power generator having a spinner structure capable of contributing improvement of efficiency of maintenance work for hub peripheral equipment.SOLUTION: A wind power generator of this invention comprises: at least one blade; a hub to which the at least one blade is rotatably attached; and a spinner including a cylindrical part extending around a rotating shaft of the hub and formed with an opening through which the blade passes and arranged to cover the hub. In addition, the cylindrical part of the spinner has such a shape that a projection line formed by projecting a crossing part between a virtual cylinder enclosing the opening and extending along a blade root of the blade and the cylindrical part against a plane including an axial line of the blade and the rotary shaft is positioned within a range enclosed by a reference straight line connecting both ends of the projection line, and a reference curved line formed by projecting the crossing line between a locus formed when the reference straight line is rotated around the rotary shaft and the virtual cylinder against the plane. |
