Abstract

A wood-type golf club head comprises a hollow structure having a geometrical arrangement for improving the directionality and carry distance of the struck ball, wherein the ratio (W/L) of a size (W) of the head in the back-and-forth direction to a size (L) of the head in the toe-heel direction is 0.85 to 1.0; and the ratio (FP/GL) of a face progression (FP) of the head to a depth (GL) of the center of gravity of the head is 0.50 to 0.75.

Claims

1. A wood-type golf club head comprising a hollow structure wherein

the ratio (W/L) of a size (W) of the head in the back-and-forth direction to a size (L) of the head in the toe-heel direction is 0.85 to 1.0, and

the ratio (FP/GL) of a face progression (FP) of the head to a depth (GL) of the center of gravity of the head is 0.50 to 0.75.

2. The golf club head according to claim 1, which has a head volume of from 400 to 470 cc.

3. The golf club head according to claim 1, which has a lateral moment of inertia of from 4000 to 5900 g sq.cm.

4. The golf club head according to claim 2, which has a lateral moment of inertia of from 4000 to 5900 g sq.cm.

5. The golf club head according to claim 1, wherein the ratio (FP/GL) is 0.65 to 0.75.

6. The golf club head according to claim 1, wherein 0=<
