The present invention provides a golf club head in which the face part is sufficiently bent when hitting a golf ball with the face part, thereby improving the flight distance and the hitting feeling. The hollow golf club head of the present invention has a head body (34) and a face member (36), the head body (34) has a face opening (32) on the ball striking surface (30), and the face member (36) For filling the face opening, part or all of the upper edge of the face opening and the upper edge of the face member extends to the crown (38).
Description
technical field [0001] This invention relates to hollow golf club heads. Background technique [0002] In the past, hollow golf club heads have the following structures, such as Figure 4 , Figure 5 As shown, it has a club head body 14 having a face opening 12 on its ball striking face 10 and a face member 16 for filling the face opening 12 (for example, see Japanese Patent Laid-Open Publication No. 2001-137396). [0003] The above-mentioned hollow golf club heads, especially the recent hollow golf club heads made of titanium alloy, can be made larger due to the improvement of manufacturing technology. In addition, not only the enlargement of the club head, but also research is progressing to improve the ease of return and pilling of the club head at the time of impact by deepening the center of gravity of the club head. [0004] Such as Figure 4 , Figure 5 As shown in the hollow golf club head, when the position of the center of gravity of the club head on the hittin...
