Abstract

A golf club includes a shaft, a grip member, and two constricting and fastening mechanisms to fasten the grip member and the shaft together; the shaft is held in the grip member at a tail portion; the grip member has locating holes, and consists of first and second half shell parts, which are secured together; each constricting and fastening mechanism includes a fastening base secured in the grip member, and fastening member facing the fastening base; the fastening base has through holes, which face the locating holes respectively; the fastening member has threaded holes, which face the through holes respectively; threaded elements are passed through the locating holes and the through holes, and joined in the threaded holes of the fastening member; thus, the shaft will be tightly sandwiched between the fastening base and the fastening member when the threaded elements are turned tight.

1 . Connecting structure of a shaft and a grip member of a golf club, comprising
 a shaft;   a grip member; the grip member having a holding room, in which a tail portion of the shaft is held; the grip member having a plurality of locating holes extending to the holding room thereof;   at least one constricting and fastening mechanism; the constricting and fastening mechanism including:   (a) a fastening base securely positioned in the grip member; the fastening base having a plurality of through holes, which face the locating holes of the grip member respectively; and   (b) a fastening member facing the fastening base; the fastening member being capable of being forced to change position relative to the fastening base; the fastening member having a plurality of threaded holes, which face the through holes of the fastening base respectively;   threaded elements being passed through the locating holes of the grip member and the through holes of the fastening base, and threadedly joined in the threaded holes of the fastening member so that the shaft is tightly sandwiched between the fastening base and the fastening member, and secured to the grip member.   
   
   
       2 . The connecting structure of a shaft and a grip member of a golf club as claimed in  claim 1 , wherein the fastening base and the fastening member of the constricting and fastening mechanism have a plurality of slip-prevention raised lines on an inner side to contact the shaft.
