BACKGROUND OF THE INVENTION [0001]The present invention is related to a golf shaft. More particularly, the invention relates to a golf shaft that facilitates replacement of a grip. [0002]The grip is one of the important parts for a golf club, and it is needed for replacing for many reasons. One reason is that the grip is able to defect or becomes old since the grip is made of rubber or leather. When the grip is defected or becomes old, a user may feel to change the grip. Another reason for replacing the grip is that a manufactured grip does not fit with the user's hand, and the user needs to change the grip. [0003]A prior golf shaft had inconvenience of replacing the grip because the user has to wrap the shaft with a masking tape first, and then the grip covers the prewrapped shaft. SUMMARY OF THE INVENTION [0004]The present invention contrives to solve a problem that has not been addressed by the prior art. [0005]An object of the invention is to provide a golf shaft with an adhesive layer that secures a grip to the shaft. [0006]To achieve the above object, the present invention provides a golf shaft includes a shaft, a grip that is surrounded with a player's hand and an adhesive layer that secures the grip to the shaft. The grip has a hollow and elongated shape and includes an outer surface, an inner surface, a top closed end and a bottom open end. The shaft includes a bottom end that fits with a clubhead and a top end that fits into the grip. The adhesive layer is formed for a predetermined length of the shaft starting near or at the top end, and the adhesive layer secures the grip firmly on the shaft. [0007]The shaft is made of a tapered tube, and the shaft is made of metal or graphite fiber. [0008]The grip is made of a rubber, synthetic leather or leather. The grip has a cylindrical shape and the top surface of the grip includes an air vent opening. [0009]The adhesive layer includes an adhesive retention layer that had a thin porous cloth member and retains an adhesive. The adhesive layer includes a heat curing adhesive, a UV curing adhesive, a pressure curing adhesive or other type of adhesives. [0010]The advantages of the present invention are: (1) a user can replace the grip fast and easy when it is needed; (2) the golf shaft does not need a masking tape during replacing the grip; and (3) the golf shaft firmly secures the grip after replacement.
