Provided is an offshore wind turbine generator capable of withstanding unevenly distributed stress with a simple and inexpensive structure and of maintaining reliability in terms of strength. An offshore wind turbine generator includes a nacelle (5) that rotatably supports a rotor head (7), and a tower portion (3) that supports the nacelle (5) and yaws integrally with the nacelle (5), and a structure portion that bears the strength of the tower portion (3) has a higher strength against a load in a direction included in a plane having a rotation axis (L) of the rotor head (7) and an extending direction of the tower portion (3) than the strength of the structure portion against a load in a direction included in other planes including the extending direction of the tower portion (3). |
