The present invention relates to a wind power generator with a changeable load part, capable of increasing rotational force of a blade part by forming larger rotational torque in a blade, rotating in a gravity direction, and reducing rotational torque in a reverse rotational direction, reducing the rotational force on a blade rotating in a reverse gravity direction. The present invention comprises: a blade part including multiple blades and a hub rotating while fixing the blades at angular intervals; a nacelle combined with the hub to be rotatable; and a tower fixing and supporting the nacelle to an upper part. The blade part includes a rotational force increasing part increasing rotational torque by having a long distance from a hub shaft in blades, rotating in a gravity direction, or reducing the rotational torque by having a short distance from the hub shaft in blades rotating in a reverse gravity direction. Therefore, the present invention is capable of improving the efficiency of the rotation of the blade part by enlarging the rotational torque in a rotational direction of the blades, and improving the efficiency of power generation by reducing the intensity of minimum wind to rotate the blade part. |
