<p>PROBLEM TO BE SOLVED: To enable the firm bonding of a face plate with a head body by forcing the former into the latter and enhance the presentable appearance of the joint part with outstanding forcing fabrication properties. SOLUTION: This head is structured of a head body 3 with a face F in which a fitting cavity 2 is formed and a face plate 4 which is forced into the fitting cavity 2. In addition, a projecting part 6 which protrudes to an opposite side is formed on at least, part of either of the inner peripheral face 2a of the fitting cavity 2 or the outer peripheral face 4a of the face plate 4. On the other hand, a recessed part 7 into which the projecting part 6 is fitted by the forcing of the face plate 4 is formed on the other. Besides, when forcing the face part 4, an inclined face part 9 which tilts in a direction in which the forcing action is guided, is formed on the head body 3 with which the face plate 4 comes into contact or the contact part T of the face part 4.</p> |
