Abstract
As the club number increases so that the loft angle is larger, the center-of-gravity height HG of each head becomes larger, and the center-of-gravity depth ZG thereof becomes smaller. Each head is hollow, and a face portion becomes thicker in its lower portion. The back bottom thickness T is smaller in an iron shorter in club length.
