The weight member is concealed in the compartment of the body to provide a good appearance while simplifying polishing procedure and allowing easy replacement of the weight member.

Claims

1. A club head comprising:

a body including at least one compartment;

at least one positioning member removably mounted in said at least one compartment;

at least one weight member mounted in said at least one positioning member; and

at least one retaining member for retaining said at least one weight member in said at least one positioning member, with said at least one weight member being concealed in said at least one compartment of the body;

wherein at least one weight member includes an axial hole having an enlarged section, said at least one retaining member being received in the enlarged section.

2. The club head as claimed in claim 1 wherein the body is an iron club head body including a back cavity, said at least one compartment being defined in a sole delimiting the back cavity.

3. The club head as claimed in claim 1 wherein the body is a wooden club head body including an inner space, said at least one compartment being defined in a sole delimiting the inner space.

4. The club head as claimed in claim 1 wherein said at least one retaining member is made of a material the same as that of the body.

5. The club head as claimed in claim 1 wherein said at least one positioning member includes a head for sealing said at least one compartment of the body.

6. The club head as claimed in claim 5 wherein the head of said at least one positioning member includes at least one driving portion for driving said at least one positioning member for mounting said at least one positioning member into said at least one compartment or removing said at least one positioning member from said at least one compartment.

7. The club head as claimed in claim 1 wherein said at least one positioning member comprises a shank including a first threaded section and a second threaded section.

8. The club head as claimed in claim 7 wherein said at least one retaining member includes a screw hole for threadedly engaging with the first threaded section.

9. The club head as claimed in claim 7 wherein said at least one compartment includes a threaded section for threadedly engaging with the second threaded section of said at least one positioning member.

10. The club head as claimed in claim 7 wherein the first threaded section has a lead different from that of the second threaded section.

11. The club head as claimed in claim 7 wherein the first threaded section has a diameter greater than that of the second thread section.

12. The club head as claimed in claim 1 wherein said at least one weight member further includes at least one resilient member fixed in an outer periphery of said at least one weight member and pressing against an inner periphery delimiting said at least one compartment for avoiding generation of odd sounds during striking.

13. The club head as claimed in claim 1 wherein the club head further comprises at least one resilient washer sandwiched between said at least one retaining member and an end face delimiting said at least one compartment.

14. The club head as claimed in claim 1 wherein said at least one compartment comprises a relatively larger outer section and a relatively smaller threaded inner section, forming a shoulder, said at least one positioning member comprising a shank including a first threaded section and a second threaded section, the second threaded section being threadedly engaged with the relatively smaller threaded inner section.

15. The club head as claimed in claim 14 wherein said at least one weight member further includes at least one resilient member fixed in an outer periphery of said at least one weight member and pressing against an inner periphery delimiting the relatively larger outer section of said at least one compartment for avoiding generation of odd sounds during striking.

16. The club head as claimed in claim 14 wherein said at least one retaining member including a screw hole for threadedly engaging with the first threaded section of said at last one positioning member.

17. The club head as claimed in claim 14 wherein said at least one weigh member includes an axial hole having an enlarged section, said at least one retaining member being received in the enlarged section.

18. The club head as claimed in claim 17 wherein the club head further comprises at least one resilient washer received in the enlarged section of the axial hole of said at least one weight member and sandwiched between said at least one retaining member and the shoulder.
