Abstract

The present invention relates to a blade for a wind power generator, and more particularly, to a blade for a wind power generator which can generate power even from weak winds as the blade is decreased or increased in length according to wind intensity and can continuously maintain a state of maximum power generation in strong winds. The blade for a wind power generator including a plurality of blades rotated by the wind includes: a body part coupled to the rotation shaft of the wind power generator; a wing part movably coupled to the body part such that the wind part is variable in length according to intensity of the wind; and an elastic part disposed between the body part and the wing part to provide elasticity in the direction in which the wing part is decreased in length.
