<p><P>PROBLEM TO BE SOLVED: To provide a golf club and a golf club head having the low gravity center. <P>SOLUTION: Ball striking devices may include: (a) a sole member 102; (b) at least one intermediate body member 108, 110; (c) a crown member 112; and (d) a face member 104. The materials making up the sole member 102, the intermediate body members 108, 110, and the crown member 112 may be selected so that the densities of the materials generally increase as one moves in a direction from the sole member 102 toward the crown member 112. Such a device as the golf club head and/or the golf club (such as wood-type golf club and golf club head) may be formed. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
