Abstract: A golf club head comprises a body defined with a hollow part thereof, an annular groove is defined in a front side of the hollow part, and an annular space is formed between the annular groove and the body. And a hitting panel, in a periphery of a rear side of the hitting panel is disposed an annular wall, and the hitting panel and the annular wall are retained in the annular groove of the body respectively. Therefore, the hitting force is blocked by the annular space, and will not transmit to the body, thus decreasing the waste of the hitting force.

Abstract: A golf club head includes a casing having a front opening and an inside retaining flange within the front opening, a face panel and a hollow loop-like coupling block fitted into the front opening of the casing and retained thereto by the inside retaining flange of the casing to hold the face panel in place, the coupling block having material properties of rigidness, structural strength and wear-resistance stronger than the casing but weaker than the face panel.

Abstract: A golf club head including a bowl-like casing integrally made from metal by forging, having a front side forming a face panel, and a smoothly curved coupling receptacle disposed at one end of the face panel at the back side; a top cover plate welded to the bowl-like casing at the top in a flush manner, the top cover plate having a plurality of rear projections raised from the rear side and supported on the top edge of the bowl-like casing at the back and then fixedly secured thereto by welding, and a plurality of smoothly and downwardly curved front projecting blocks respectively abutted against the back side of the face panel and then fixedly secured thereto by welding; and, a neck tube inserted through the side notch of the top cover plate into the coupling receptacle of the bowl-like casing and then fixedly welded thereto at the desired angle.
