ABSTRACT:
A head structure for a golf club, has a head body having a face for providing a ball hitting surface and a balancing weight made denser than the head body which is press-fitted so firmly on the head body that it may not come out. The press-fitting is accomplished by a combination of dovetail joint or the like. The dovetail joint includes a fitting mortise flaring towards its bottom and extending longitudinally of one of the head body and the balancing weight, and a corresponding fitting tenon flaring to have a width diminishing towards its root and extending longitudinally of the other so that it may be firmly fitted in the mortise.
