できなかった。However, the conventional hollow wood type golf club head has a face wall portion a as shown in FIG.
Since the wall thickness of the golf ball is set to be substantially uniform and the natural frequency has not been designed to be reduced, the primary natural frequency of the face wall portion a becomes a significantly larger value than the primary natural frequency of the golf ball. However, the flight distance performance could not be fully exhibited.
