A notched portion 3a is provided in the rear surface of the face insert 3 to extend upward from the lower edge portion. The notched portion 3a extends from the left end of the face insert 3 to its right end. An upper edge portion 3b on the rear surface of the face insert 3 abuts against the back wall surface of the recessed portion 2H. A bolt 6 inserted in each bolt insertion hole 5 is screwed into the female screw hole 3c, thereby fixing the face insert 3 on the head body 2. A viscoelastic material 7 may be provided in the notched portion 3a. <P>COPYRIGHT: (C)2012,JPO&INPIT |
