<p>PROBLEM TO BE SOLVED: To enable a golfer to hit a ball at a stable stroke with the excellent directivity of the hit ball by disposing a point where the virtual plane passing the centroid point of a putter head part and the extension line of the shaft of a neck part nearer the toe part side of the putter head part than the centroid point of the head. SOLUTION: The neck part N for mounting the shaft S0 is arranged in the heel part Hh of the putter head part H1 in the positional relation where the putter club P is set in the position for hitting the ball and is viewed from above. The putter club is constituted by disposing the point where the virtual plane X of the centroid height passing the centroid point G1 of the putter head part H1 and the extension line of the shaft S0 disposed in the neck part N1 are intersected nearer the toe part Ht side of the putter head part H1 than the centroid point G1 of the putter head part H1 . Namely, the spacing indicated by d1 exists between the shaft passing point S1 and the head centroid point G1 . As a result, the weight of the putter head part H1 is distributed to the heel part Hh side as far as possible, by which the effect by the head gravity PG is made sure.</p> |
