た。2. Description of the Related Art Hitherto, a golf club head having a high resilience has been demanded. In particular, much research has been made on a face structure. As one of them, recently, there is a tendency that the face thickness of a metal head is reduced to increase rebound and try to hit a ball. However, since the face is a portion where the ball is hit directly, there is a limit to thinning. On the other hand, the body of a general golf club head is considered to vibrate or bend microscopically when hitting a ball, but it has been difficult for the body to absorb the whole body and repel efficiently.

Discloses a golf club head in which a ball striking member and a head main body are connected by an elastic body made of a wavy spring steel, thereby increasing the effective ball striking area and stabilizing the ball striking direction.
Also, JP-A-10-263118 (known example 2) describes that
A golf club head having a deformation promoting portion formed on the top (crown) or face of a head body is disclosed.
In this case, the deformation promoting portion is formed by a through hole or a thin groove, or is formed by filling a material having a small Young's modulus into these holes or grooves. Also, Japanese Patent Application Laid-Open No. 10-1
No. 14102 (known example 3) discloses a golf club head in which the angle of a top-side inclined portion and the angle of a sole-side inclined portion are substantially equal in a face peripheral region to repel the face in a well-balanced manner. Also discloses a technique in which an inclined portion has a wavy shape.

The three members of the body 10 are formed by a metal material such as stainless steel, and are joined by, for example, welding or the like to the body rear side 3, the body front side 5 having a shaft fastening portion or a bent portion described later, and the face 10. And are integrally formed (the welded portion is indicated by reference numeral C). These three members
Each of them is formed by casting, forging, or pressing. In this case, the body rear side portion 3 and the body front side portion 5 further separate the top 1a, the sole 1b, the toe 1c, the heel 1d, and the (back 1e) portion from each other (arbitrary members may be integrated). The head may be formed by integrating these separate members (outer shell members) by welding or the like.

It is formed so as to reach the inside of the head from the face edge P2. Specifically, the bent portion is formed such that the position P1 at the bottom thereof is located more inward of the head than the face edge P2, and the depth (the distance between P1 and P2) to the bottom of the bent portion 5b is reduced. 1 to 15 mm, preferably 3

トップ1aの肉厚T1よりも厚く形成されている。Further, since the bent portion is formed so as to be microscopically bent at the time of hitting the ball as described below, the thickness thereof is formed thicker than the outer shell member so as not to be damaged. Specifically, the thickness T2 at the bent portion is
It is formed thicker than the thickness T1 of the top 1a.

しかも、屈曲部は、強度を低下させることなく、トップ
より厚肉にしているため、破損が防止されている。By forming the bent portion 5b as described above, the bent portion provided closer to the face of the body than the entire body at the time of hitting the ball can be bent microscopically, and the stress at the time of hitting the ball can be reduced. The flight distance of the hit ball can be improved by the rebound of the bent portion without dispersing the ball. In addition, the contact of the hit ball with the face is prolonged, the directionality is stabilized, and a soft hit feeling can be obtained.
Moreover, since the bent portion is made thicker than the top without lowering the strength, breakage is prevented.
【0016】そして、このような効果がより得られるよ

T3とすることが好ましい。The bent portion 5b is formed behind the face edge P2 and forward of the highest portion P of the top 1a.
The thickness T2 of the bent portion 5b is equal to the thickness T of the face 10.
Make it thinner than 3. With this configuration, it is easy to obtain a high rebound not only at the face 10 but also at the bent portion. In this case, when the head is a driver, the thickness T1 of the top 1a is 0.5 to 1.5 mm, and the thickness T1 of the bent portion 5b is
2 is 1.0 to 3.0 mm, and the thickness T3 of the face 10
Is formed in the range of 1.8 to 3.5 mm, and T1 <T2 <
It is preferably T3.

易になる。Further, from the face edge P2 to the bent portion 5b
If the distance L to the center of the bottom of the groove (see FIG. 2) is too short, the bent portion and the face come into contact at the time of hitting the ball, and if too long, the weight of the body rear side portion 3 becomes too light.
It is preferable to set the length to not less than m and not more than 20 mm. In this case, by forming the bent portion 5b at substantially the same distance from the face edge (L is substantially constant over the entire bent portion), the repulsion timing at the time of hitting the ball becomes common, and the hit ball is hit. The directionality can be stably improved.
When the highest part P of the top 1a is located at the welded portion C between the rear body part 3 and the front body part 5, the manufacture of the body becomes easy.

In the modification shown in FIG. 6, the bent portion 5b is formed so that the grooves on the top side and the sole side match the face angle (loft angle). That is, the bent portions on the top side and the sole side and the bent portions on the toe side and the heel side are formed to face each other, and the front wall 5c, the rear wall 5d and the face 10 in the bent portions are inclined in substantially the same direction. .
【0020】このような構成によれば、打球時における
屈曲部の反発の方向が共通し、ロフト角通りに打球で
き、打球が安定して方向性が良くなる。According to such a configuration, the direction of rebound of the bent portion at the time of hitting the ball is common, the ball can be hit at the loft angle, and the shot is stable and the directionality is improved.

の早い人に適したヘッドとなる。The modification shown in FIG. 7 shows an example in which a bent portion 5h is formed so as to have a U-shaped groove with a sharp bottom. That is, the groove of the bent portion is inclined so that the front wall 5c and the rear wall 5d open outward without a bottom wall, and the front wall is formed so that the inclination of the front wall is larger than the inclination of the rear wall. . Therefore, a quick rebound can be expected, and the head is suitable for a person with a high head speed.

And shows an integrated configuration (two-piece structure). Because of this, there is no weld at the face edge,
Face edges are less likely to be damaged. As described above, the number of components constituting the head structure, the division position, and the like can be appropriately modified.
