Description

  The present invention relates to a golf club head, and more particularly to a golf club head excellent in the effect of absorbing vibration and impact at the time of hitting a ball.

  As shown in FIGS. 10 and 11, the conventional metal wood golf club head 1 has an opening 111 on the side of the head body 11 where a ball is hit, and the opening is made by a face plate 12 for hitting a ball by, for example, a welding method. A hollow structure coated with 111. Although this conventional structure can be significantly reduced in weight and the load applied to both hands can be reduced, there is no structure for absorbing vibrations when hitting the ball, and the ball impact generated on the face plate 12 is directly applied to the golfer. It is reported to the arm, causing a motor injury to the golfer's arm and making it impossible to enjoy golf.

  FIG. 12 shows a club head having a vibration absorbing function (Patent Document 1). The club head 2 has an opening 211 on the side on which the head body 21 having a hollow structure is hit, and the face plate 22 is covered with the opening 211 by, for example, welding. A vibration absorbing means in which a cavity 23 is filled with a semi-fluid liquid 24 having a predetermined viscosity is provided. The vibration applied to the club head can be damped by the viscosity of the liquid 24.

However, the club head 2 can effectively attenuate the impact applied to the face plate 22 by the viscosity of the liquid filled in the cavity 23. However, the impact due to the face plate 22 is repeatedly applied, and the cavity becomes hollow as it is used for a long time. 23 may be broken and the liquid 24 may leak. In addition, the vibration absorbing means takes time for manufacturing due to complicated construction such as injection of the liquid 24 and welding at the bottom, resulting in an increase in cost. Further, there is a problem that the inertial force of the liquid 24 having a predetermined stickiness affects the swing stability of the golfer.
