ABSTRACT:
A golf club includes a shaft and a rubber mounting seat which is provided on the shaft. The mounting seat confines a blind bore with a hemispherical bottom and has an open top end and an annular flange which projects inwardly from the open top end. A position indicator is received in the blind bore and includes a cylinder body which has a hemispherical bottom, a top end that is formed with a fluid cavity and a window that covers the fluid cavity. The window has a position marker formed thereon. The fluid cavity contains a volume of liquid therein. The liquid forms a positioning bubble beneath the window. The hemispherical bottom of the cylinder body extends into and is in frictional contact with the hemispherical bottom of the blind bore to permit tilting and rotative adjustments of the cylinder body within the blind bore. The cylinder body is initially adjusted so as to move the position marker to a desired position which corresponds to an optimum golf club striking position of a golfer. The golf club is then adjustably inclined during succeeding use so as to align the positioning bubble with the position marker.
