Summary:The utility model discloses a fan blade for a wind turbine generator. The fan blade comprises a curved plate, a planar plate and a connection element used for installing the fan blade on a rotary centre device, wherein a recessed structure is formed at the middle portion of the curved plate, a resistance portion is arranged at one side of the curved plate, and a plurality of jet nozzles are formed close to the resistance portion; the planar plate is fixedly connected to the edge of the curved plate, and partially covers the middle recessed structure of the curved plate. The fan blade for the wind turbine generator is simple in structure, and greatly adaptive to protection and start-up in case of a high wind speed and a low wind speed.
