<p><P>PROBLEM TO BE SOLVED: To provide a putter structure with which the position of a head to a ball and the lie angle of a putter at the position of the head are set to be fixed in the setup of the putter. <P>SOLUTION: A mark 9a is provided on an optional position at the lower part of a shaft 2b of the putter 1b, the mark 9a and the head upper surface 8 of the head 4a of the putter are connected by a visual line 12b, and a visual line pointing position moving width 15 is generated among a visual line pointing position 14a on the head upper surface 8, a visual line 12e by the movement of the position of the head and the visual line pointing position 14b below the mark 9a connected by the visual line 12e. Thus, the moving degree of the head in the case of fixing the lie angle 13a of the putter 1b is recognized. Also, even in the case that the position of the head is fixed and the lie angle is changed, since the direction of the visual line with the mark 9a as a supporting point is changed, the changing degree of the lie angle is recognized. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
