         2 . The golf club according to  claim 1 , wherein a position indicator indicating a rotation position is provided on a portion of the second adapter that is exposed through the second opening portion. 
     
     
         3 . The golf club according to  claim 1 ,
 wherein the first adapter has the first end portion and the second end portion at respective ends of a first axis, and is formed so as to be tube-shaped and extend along the first axis, and the shaft receiving recessed portion extends along a second axis that intersects the first axis,   the second adapter has the first end portion and the second end portion at respective ends of a first axis, and is formed so as to be tube-shaped and extend along the first axis, and the first coupling portion extends along a second axis that intersects the first axis,   the coupling portion of the first adapter and the first coupling portion of the second adapter can be coupled at a plurality of rotation positions about the second axis of the second adapter, and   the second coupling portion of the second adapter and the hosel coupling portion of the hosel portion can be coupled at a plurality of rotation positions about the first axis of the second adapter.   
     
     
         4 . The golf club according to  claim 3 ,
 wherein the coupling portion of the first adapter has a tube-shaped protruding portion, and   the first coupling portion of the second adapter has a recessed portion for receiving the coupling portion of the first adapter.   
     
     
         5 . The golf club according to  claim 4 ,
 wherein a plurality of projections that extend in the first axis direction of the first adapter are formed on a surface of the protruding portion of the coupling portion of the first adapter, and   a plurality of grooves that extend in the second axis direction of the second adapter and are for receiving the plurality of projections are formed in the recessed portion of the first coupling portion of the second adapter.   
     
     
         6 . The golf club according to  claims 1 ,
 wherein the second coupling portion of the second adapter is configured by an outer peripheral surface of the second adapter that is formed so as to be polygonal, and   the hosel coupling portion has a polygonal inner wall surface for receiving the second coupling portion.   
     
     
         7 . The golf club according to  claim 1 , further comprising a cover member that removably closes the first opening portion. 
     
     
         8 . The golf club according to  claim 7 , wherein a through-hole for insertion of a tool capable of operating the fastener is formed in the cover member. 
     
     
         9 . The golf club according to  claim 1 , wherein a flange capable of coming into contact with a peripheral edge of an opening of the hosel portion is formed in the first end portion of the first adapter, and a position indicator indicating a rotation position is provided in the flange portion. 
     
     
         10 . The golf club according to  claim 1 ,
 wherein the interior space of the hosel portion is defined by a small-diameter portion and a large-diameter portion that is continuous with the small-diameter portion and is in communication with the first opening portion, and   the small-diameter portion is formed so as to be tapered such that the diameter increases as the small-diameter portion extends toward the large-diameter portion.
