Abstract:
A propeller, wherein the tip parts of the propeller blades of a horizontal-shaft windmill are tilted in the front direction of the propeller blades to form inclination parts. The inclination angle of the tilted parts is set within the range of 25 to 50° relative to the longitudinal direction of the propeller blades.
