    摘要: In a high-lift-device, a wing, and noise reduction device for a high-lift-device that are capable of reducing noise generated when a flap is extended, preventing deterioration of aerodynamics characteristic when retracting the flap, and preventing an increase in weight, a flap main body (5) disposed so as to be extendable/retractable relative to a main wing and a protruding portion (6A-1) that smoothly protrudes at least at the vicinity of one end portion of a positive-pressure surface (PS) of the flap main body (5) in a direction away from the flap main body (5) are provided.
