Abstract
A centroid-adjustable golf club head, which can enable a user to strike ball more stably and accurately, is disclosed. The centroid-adjustable golf club head includes a head body, a sphericity, a floating ball and liquid with large specific weight. The head body has anti vibration and thermoplastic elastomer disposed therein and defines a screw hole at a top thereof. The sphericity is disposed in the anti vibration and thermoplastic elastomer of the head body. The sphericity has a charging spout formed on a top thereof and aligned with the screw hole of the head body; and a elastic wafer disposed between the head body and the sphericity. The floating ball is disposed in the sphericity. The liquid with large specific weight is fed from the charging spout to the sphericity. With this arrangement, the centroid of the club head can be adjusted to an appropriate position, depending to the relative position of the liquid and the floating ball. Therefore, the user can strike the ball stably in any time and by any angle.
