<p>PURPOSE: To enable a ball to be shot with good directivity into a high trajectory by achieving a great depth for the center of gravity and a low center of gravity, etc. CONSTITUTION: This wood head 1 is constructed of a metallic shell 2. A longitudinally extending recess 5 that extends backwards from a position a predetermined distance away from the back of a face-forming shell wall 6 and that opens to a back face 7 is provided in the cross-direction center of the sole 4. The front of the recess 5 is formed into a parallel portion 9, and the rear of the recess 5 is formed into a divergent portion 10 that gets wider backwards.</p> |
