Abstract
A golf club enables a golf ball to be hit farther without a decrease in ball traveling distance even if it is struck at a lower point on the club head face. A driver club head includes a face having a hitting surface, a sole forming the bottom of the head, etc. The sole is modified for improvement by providing an elastically deformable area having a recessed or projected configuration at a position of the sole closer to the face. The deformable area includes a bent portion formed at the lower end of the face. A bend is formed between the bent portion and the sole at an obtuse angle. The sole is provided with a recess or a projection to lower the rigidity of the sole. Thus, repulsion is enhanced to increase the ball traveling distance even if the ball is struck at a lower point on the face.
