1. A golf club grip for a golf club including a shaft and a club head attached to a lower end of the shaft, wherein said golf club grip comprises: at least a second member which is rubber made tube having a lower end, an upper end and a gripping surface defining between the upper end and the lower end; at least a first member which is rubber made tube having an upper end and a lower end coaxially integrated with said upper end of said second member to form an elongated integral tubular body for attaching to an upper end portion of said shaft of said golf club, wherein said first member has an outer circumferential surface integrally extended from said gripping surface of said second member, wherein said first and second members have different natures to provide two different properties of said golf club grip; and a rubber made endpiece integrally formed at said upper end of said second member.

2. The golf club grip, as recited in claim 1, wherein said first and second members have different hardness.

3. The golf club grip, as recited in claim 2, wherein said second member is softer than said first member.

4. The golf club grip, as recited in claim 1, wherein said outer circumferential surface of said first member and said gripping surface of said second member have different friction.

5. The golf club grip, as recited in claim 2, wherein said outer circumferential surface of said first member and said gripping surface of said second member have different friction.

6. The golf club grip, as recited in claim 4, wherein said outer circumferential surface of said first member has greater friction than said gripping surface of said second member.

7. The golf club grip, as recited in claim 1, wherein each of said first and second members has a viscosity to provide a predetermined stickiness on each of said gripping surface and said outer circumferential surface.

8. The golf club grip, as recited in claim 5, wherein each of said first and second members has a viscosity to provide a predetermined stickiness on each of said gripping surface and said outer circumferential surface.

9. The golf club grip, as recited in claim 7, wherein said first member is much sticky than said second member.

10. The golf club grip, as recited in claim 1, wherein said first and second member have different colors.

11. The golf club grip, as recited in claim 8, wherein said first and second member have different colors.

12. The golf club grip, as recited in claim 1, wherein said first and second member have different fabric textiles.

13. The golf club grip, as recited in claim 11, wherein said first and second member have different fabric textiles.

14. The golf club grip, as recited in claim 12, wherein said second member comprises a thin reinforced rubber layer laminated with cotton yarn to form said fabric textile of said first member.

15. A method of manufacturing a golf club grip for a golf club including a shaft and a club head attached to a lower end of the shaft, wherein the method comprises the steps of: (a) preparing a first raw rubber layer which is shaped and sized to form at least a pair of first rubber pieces; (b) preparing a second raw rubber layer which is shaped and sized to form at least a pair of second rubber pieces; (c) aligning said pair of first rubber pieces with said pair of second rubber pieces in an end to end manner in two halves of heat mold respectively; and (d) forming said pair of first rubber pieces and said pair of first rubber pieces in said heat mold to form said golf club grip including a tubular first member and a tubular second member coaxially extended from a lower end of said first member, wherein said raw rubber of said pair of first rubber pieces is integrated to form said tubular first member, wherein said raw rubber of said pair of second rubber pieces is extended from said lower end of said first rubber piece to form said second member which is integrated coaxially with said first member, wherein said first and second members have different natures to provide two different properties of said golf club grip.

16. The method as recited in claim 15, in the steps (a) and (b), further comprising a step of adding additives into at least one of said first raw rubber layer and said second raw rubber layer so as to provide different hardness for said first and second members.

17. The method, as recited in claim 16, wherein said second member is softer than said first member.

18. The method as recited in claim 15, in the steps (a) and (b), further comprising a step of adding additives into at least one of said first raw rubber layer and said second raw rubber layer such that each of said first and second members has a viscosity to provide a predetermined stickiness on said outer circumferential surfaces for said first and second members.

19. The method, as recited in claim 18, wherein said first member is much sticky than said second member.

20. The method as recited in claim 15, in the steps (a) and (b), further comprising a step of coloring at least one of said first raw rubber layer and said second raw rubber layer to provide different colors for said first and second members.

21. The method as recited in claim 15, in step (b), further comprising a step of overlapping a textile fabric on an exterior surface of each of said first rubber pieces and painting a rubber latex on said textile fabric to attach said textile fabric on said exterior surface of said first rubber piece, wherein said textile fabric is treated to integrally coat on an outer circumferential surface of said second member, in step (d), to form a frictional coarse surface thereof while said first member contains no fabric textile so as to provide two different frictional surfaces of said first and second members.
