Abstract
There is provided a golf club capable of giving a strong backspin to a golf ball. A shaft 4 is connected to a head 2 formed with score lines 10 on a face surface 1 thereof. A height D from a sole face 6 of the head 2 or a horizontal plane flush with the sole face 6 is formed greater than a radius E of a golf ball 22. An upper protrusion 18 and a lower protrusion 15 are provided spacedly rearwardly of upper and lower portions of the head 2, respectively. By providing the center of gravity 21 of the head 2 in an upper portion than the center 23 of the golf ball 22, backspin can be accelerated by a gear effect generated at the time of hitting the golf ball 22. Further, the height D of up to the center of gravity 21 of the head 2 is freely adjustable.
