<p>PURPOSE:To enable the free distribution of weights without hindering appearance and the easy production of the golf club head by integrally forming at least either of a projecting part and recessed part on the surface of the head body covered or concealed by a face plate, thereby providing the weight distribution of the golf club head. CONSTITUTION:The face plate 3 consists of a low sp. gr. maternal and the head bode 4 is constitutes of for example, a metal having the sp. gr. larger than the sp. gr. of the face plate 3. The face plate 3 is fixed to the body 4. At least either of the projecting part or recessed part to determine the characteristics of the golf club head is integrally formed on the surface of the head body 4 covered and concealed by the face plate 3; for example, the projecting part 9 is integrally formed on the central surface of the head body surface 8 facing the surface on the side opposite from the hitting face 2 of the face plate 3. As a result, the weight distribution is so set that the weight concentrate to the central part of the head. A hammer effect is thus enhanced by applying large impact force on the ball.</p> |
