PROBLEM TO BE SOLVED: To prevent falling of a vibration absorption material surely and improve efficiency of a filling work of the vibration absorption material.SOLUTION: A head body 12 comprises a frame part 32 to which an outer peripheral part of a face member 14 is attached and a face surface 1602 side is a front surface. The frame part 32 comprises an outer peripheral wall part 34, a support wall part 36, and a rear wall part 38, and the support wall part 36 has a reception surface 3602 which can contact an outer peripheral part of a face rear surface 1604. An upward open-state space 3804 is formed between a rear wall surface 3802 and the face rear surface 1604. A vibration absorption material 40 is filled in the space 3804. The support wall part 36 has an open-state slit 42 extending in a direction crossing an extension direction of the support wall part 36, being open to an upper end surface 3604. The vibration absorption material 40 is filled from the space 3804 over the slit 42, and the vibration absorption material 40 filled in the slit 42 exhibits an anchor effect for surely preventing falling of the vibration absorption material 40.SELECTED DRAWING: Figure 7 |
