<p>PROBLEM TO BE SOLVED: To obtain a tee club with which the exact checking of the 'ball and eye position' meeting the stroke posture of a golfer is possible, i.e., the sure execution of an 'address check' is possible. SOLUTION: The head 2 of the putter club 1 is provided with a cylindrical hole 20 penetrated approximately parallel with a visual line connecting the eye 3 of the golfer addressing the ball and the head 2 existing on the vertical line V thereof. When the golfer views the hole 20 of the head 2 from the addressing, the golfer's eye 3 eventually exists right above the hole 20 if the hole 20 appears approximately round. If the position is assumed to be the address meeting the golfer's own stroke posture, the golfer assumes the addressing position of 'the eye existing outside the ball' in case the inside surface having a crescent shape on the lower side is visible to the golfer's eye. The sure conduction of the 'address check' by the ways of the hole 20 is thus made possible.</p> |
