ABSTRACT:
A golf club head has a plurality of small air holes in a striking face, an air guide through hole communicating with the small air holes and extending through the interior of the head laterally to open to an opposite side of the striking face. A vertical hole extends upright from the sole of the head to communicate with the guide air, a spring, a round bar bored with a center hole, and a screw are orderly fitted in the vertical hole. The screw is able to be screwed inward or outward to push the round bar inward or outward to let the area of the center hole communicating with the air guide through hole change so as to alter the air volume or speed passing through the air guide hole and thus reduce air resistance of the striking face.
