ABSTRACT:
A golf club with less limitations to materials usable for a balance weight on a outer face of a sole, having a structure for the balance weight to be easily fixed to a head body. A hollow head body 16 of a long iron has an outer shell formed with a through-hole 21, corresponding to the sole 4 portion. A projection 34 is formed on an upper face of the balance weight 31 so that the projection 34 is inserted into the through-hole 21. Another through-hole 35 is formed in the projection 34, into which is pressed a taper pin 36 to be anchored there. As a result, the balance weight 31 is securely fixed to the head body 16. Unlike the fixing by caulking a balance weight itself, the invention does not need the extensibility of the material of the weight 31. Accordingly, tungsten-based materials, for example, are also made usable.
