Abstract:
PROBLEM TO BE SOLVED: To make a player feel easily address a golf club by positioning the cross point of an upper curve of the face part and a side curve of the face heel part of the golf club head to the side sole part of the reference line in the face side and connecting the reference line by a straight line to the cross point of the hosel reference line and the face reference line. SOLUTION: The cross point P) of the upper curve R of a face 3 and a side curve S of the face 3 to the heel 2 side is positioned to the side sole side of a face side periphery line (reference line Ln1 ) parallel with the longitudinal axial line of a hosel 8. Further, the reference line Ln1 is connected by a straight line to the cross point of a curve S in the side of the heel face side and the longitudinal axial line of a hosel 8. By this constitution, the distance of the center of gravity is made longer, the depth of the center of gravity deeper, the angle of the center of gravity larger, and the direction of the face is made clear to make a player to feel easy-to-address.
