When a general player uses such an iron club, in a long iron having a long club length and a small loft angle, the shaft is bent by the swing and the face surface of the head is shifted to the target flight line of the ball. The head tends to open when hitting the ball, and the hit ball tends to be sliced.In short irons with a short club length and a large loft angle, the head turns to the left and the hit ball hooks. There was a drawback that it was easy to do.

Since the first weight bodies 44 to 46 and the second weight bodies 47 are mounted along the banks 38 to 40, the function of the head bodies 32 to 34 as cavity backs is impaired also in this embodiment. Without the head body 32
As a result, the weight of ~ 34 is distributed to the peripheral portion, and the moment of inertia at the time of hitting the ball is secured. Therefore, according to the present embodiment, a large moment of inertia can be obtained at the time of hitting the ball as compared with the conventional example shown in FIGS. 13 to 15, so that the head is not shaken, and the hook by the long iron and the slice by the short iron are prevented. Together with the ability to do so, the directionality of the hit ball has been dramatically improved.
