CONSTITUTION: A pile driving head for preventing eccentricity and noise comprises a main body(12), a hammer cushion(14), a head cushion(20), multiple elastic members(30), and an eccentricity prevention device(40). The body has a hollow part. The hammer cushion is inserted in the upper part of the hollow part. The head cushion is located under the hammer cushion and is fixed in a head cushion guide(22). The head cushion guide is inserted in a head cushion guide hole(25) formed on the outer surface of the main body.
