Golf club and method for manufacturing same

Abstract

The inner circumference of the receiving portion is tapered so as to allow the width thereof to be gradually wider from a bottom portion toward an aperture portion thereof. The outer circumference of the face member is tapered so as to allow the width thereof to be substantially equal to that of the aperture portion and gradually wider from a rear portion toward a front portion thereof. The depth of the receiving portion is defined so as to be slightly larger than the thickness between the front portion and the rear portion. By fitting the face member into the receiving portion in a manner dropping into receiving portion, the face member and the receiving portion can be accurately fitted with each other without a gap at a comparatively low cost even if their dimensional accuracies are low.

1 . A golf club comprising: a head made of a plurality of metallic members; and a shaft connected to said head, said head comprising: one member formed with a receiving portion; and an other member fitted into said receiving portion so as to be integrated with each other, wherein: 
 an inner circumference of said receiving portion is tapered so as to allow a width thereof to be gradually wider from a bottom portion toward an aperture portion thereof;    an outer circumference of said other member is tapered so as to allow a width thereof to be gradually wider from a rear portion toward a front portion thereof; and    a depth of said receiving portion is defined so as to be slightly larger than a thickness between said front portion and said rear portion.    
   
   
       2 . The golf club according to  claim 1 , wherein: 
 the width of said front portion of said other member is substantially equal to the width of said aperture portion of said receiving portion; and    a taper angle of said inner circumference is substantially equal to a taper angle of said outer circumference.    
   
   
       3 . The golf club according to  claim 1 , wherein: 
 said one member is a head body connected to said shaft;    said receiving portion is formed on a region of said head body corresponding to a face thereof; and    said other member is a face member.    
   
   
       4 . The golf club according to  claim 2 , wherein: 
 said one member is a head body connected to said shaft;    said receiving portion is formed on a region of said head body corresponding to a face thereof; and    said other member is a face member.    
   
   
       5 . The golf club according to  claim 1 , wherein said one member and said other member are made from different metals, respectively.  
   
   
       6 . The golf club according to  claim 5 , wherein said other member is made from metal having larger specific weight than that of said one member.  
   
   
       7 . A method for manufacturing a golf club, said golf club comprising: a head made of a plurality of metallic members; and a shaft connected to said head, said head comprising: one member formed with a receiving portion; and an other member fitted into said receiving portion so as to be integrated with each other, wherein said method comprising steps of: 
 forming an inner circumference of said receiving portion to be tapered so as to allow a width thereof to be gradually wider from a bottom portion toward an aperture portion thereof;    forming an outer circumference of said other member to be tapered so as to allow a width thereof to be substantially equal to the width of said aperture portion and gradually wider from a rear portion toward a front portion thereof;    defining a depth of said receiving portion to be slightly larger than a thickness between said front portion and said rear portion; and    fitting said other member into said receiving portion in a manner dropping into the recess portion of said one member toward the recess portion of said receiving portion via a clearance between the rear portion and the recess portion.    
   
   
       8 . The method for manufacturing the golf club according to  claim 5 , wherein: 
 said one member is a head body connected to said shaft;    said receiving portion is formed on a region of said head body corresponding to a face; and    said other member is a face member.    
   
   
       9 . The method for manufacturing the golf club according to  claim 7 , wherein said one member and said other member are made from different metals, respectively.  
   
   
       10 . The method for manufacturing the golf club according to  claim 9 , wherein said other member is made from metal having larger specific weight than that of said one member.
