Wind turbine generator

摘要

A wind turbine generator that can eliminate the penetration of rainwater and prevent the occurrence of failure is provided. The wind turbine generator includes: a plurality of wind-turbine rotor blades (6) for receiving wind power; a rotor head (4) to which the plurality of wind-turbine rotor blades (6) are attached, the rotor head (4) being rotated and driven by the wind power received by the plurality of wind-turbine rotor blades (6); a head capsule (5) for covering the rotor head (4); a blade-side disc portion (31) that extends from each wind-turbine rotor blade (6) radially outward of the wind-turbine rotor blade (6) and is inclined toward the head capsule (5); a cylindrical portion (22) that is disposed substantially coaxial with each wind-turbine rotor blade (6) and extends from the head capsule (5) toward the tip of the wind-turbine rotor blade (6); a capsule-side disc portion (23) extending radially outward from each cylindrical portion (22); and a bent portion (24) that extends radially outward from the outer circumferential edge of each capsule-side disc portion (23) and is inclined toward the tip of the wind-turbine rotor blade (6).
