PUTTER OF ACCURATELY HITTING BALL WITHOUT FALSE SENSE OF DISTANCE AND GOLF CLUB OF HITTING STRAIGHT BALL WITH GREAT CARRY DUE TO ITS SPIN CONTROL

摘要

PPROBLEM TO BE SOLVED: To provide a putter club of accurately hitting a ball without false sense of distance. PSOLUTION: This putter uses a needle bearing or an oilless bearing that acts on its hitting face 5 only in the horizontal direction to minimize the ball's spin in the horizontal direction caused by an erroneous hit. It is also designed to get rid of possible false sense of distance when the club is held in place by using an illusionary path equation, an L-shaped pendulum 2, a long slit window 4 for the light intake on the side wall and the like.
