This wind power generator (1) comprises: a nacelle (10) that houses a generator; a tower (20) whose top end section is connected to the nacelle (10) and whose bottom end section is fastened to a base section; and a rotor (30) that is located on the downwind side of the nacelle during normal operation, and that by receiving the force of the wind and rotating, drives the generator. The rotor (30) has a hub (31) rotatably supported and blades (32) extending radially from the hub. The blades (32), when not loaded, are pre-bent blades that are formed such that the middle section (33c) of each blade (32) is curved outward with respect to a straight line connecting the root end section (32a) of the blade attached to the hub and the tip end (32b) section on the outer diameter side of the rotor (30), and mounted at a specified coning angle. |
