Abstract

A golf club is provided incorporating a head having an optimum loft angle, and lie angle for respective golfers. Moreover the golf club has minimal head deflection when striking a golf ball, and improved strength. To achieve this, a head attachment portion 13 disposed at a rear face 4A of a face 4, is substantially horizontally connected to a base end 9B of a shaft attachment portion 9. The shaft attachment portion 9 is connected to the face 4 via the head attachment portion 13. The face 4 and the shaft attachment portion 9 connected to the head attachment portion 13 are made separate, and hence at the time of assembling the various combinations, the loft angle and the lie angle can be freely adjusted. The impact force of a golf ball is transmitted directly from the face 4 to the head attachment portion 31, and the transmission force can be transmitted directly to the shaft 3 via the shaft attachment portion 9. Hence the transmission path can be increased so that the possibility of head 2 distortion at the time of striking a ball is minimal.

Claims

1. A golf club with a head body including a face for contacting a golf ball, a rear shell and a hollow region between said face and said rear shell, a shaft attachment portion provided on one side of the face of the head body, and a shaft connected to a tip end of said shaft attachment portion, wherein a head attachment portion extends inside said hollow region, said head attachment portion being connected to said shaft attachment portion.

A golf club according to claim 3, wherein said head attachment portion extends from a base end of said shaft attachment portion, spanning approximately from a heel of said head body to a toe, and said shaft attachment portion is connected to said head body by means of said head attachment portion.

5. A golf club according to claim 4, wherein said head attachment portion is formed substantially horizontal.

6. A golf club according to claim 2, wherein said head attachment portion is formed into an approximate loop shape along an edge of said face.

7. A golf club according to claim 2, wherein said head attachment portion is fixed to an upper face of said sole.
