<p><P>PROBLEM TO BE SOLVED: To provide a golf club allowing a player to swing the golf club in such a way that a ball can hit a sweet spot 3 without a sense of discomfort by easily turning the club face 2 toward a target from the visual line in addressing without being affected by the structure of the club head, and by squarely recognizing the hitting direction on a line 1 passing the target and the ball. <P>SOLUTION: A crown 8 has such an illusional pattern as to be sensed to move visually in the same direction as the line 1 passing the target and the ball visually recognized from the visual line in addressing. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
