The present invention relates to a rotor shaft of a wind power generator. The rotor shaft of a wind power generator comprises: a main body including a first connection flange integrally formed on a hub part on an outer circumference of the main body; a second connection flange produced separately from the main body to be connected with the first connection flange of the main body; and a fastening bolt fixing the second contact flange onto the first connection flange of the main body. The rotor shaft of a wind power generator can be conveniently produced by conventional production equipment and can remarkably reduce production costs. |
