Description of the Related Art In order to increase the flight distance of a wood club, a face structure in which a plurality of plate members are laminated has been proposed (JP-A-9-239076). By reducing the spring constant of the face member, the restoring force of the bending of the face when the face collides with the ball is increased, the initial velocity of the hit ball is increased, and the flight distance is increased. Further, due to the displacement displacement of the laminated plates, the spring constant becomes lower than that of a single plate having the same thickness as the total plate thickness, so that the face thickness is not excessively reduced and the impact resistance strength of the face member is not lowered. Has been done.

１０２の破損がクローズアップされてくる。However, in the club head having the face member having the multi-layer structure, as shown in FIG. 4, the multi-layer structure is formed at the peripheral portion of the face-side opening of the bowl-shaped head body 100. The peripheral edge portion of the face member 101 is simply welded or adhered (welded portion 102). Therefore, when the impact of a hit ball is repeatedly received, the welded portion 102
There was a problem that it was easily damaged. In particular, in the head of the wood club to which the present invention is applied, since the face member is a laminated plate, the spring constant is small, and the deflection at the time of impact is large as compared with the face having the conventional single-plate structure. The damage is coming up close.

The thickness is thin. As a result, in the head provided with the face member 6 including the laminated portion 10, when the simple fixing method of the face member 101 and the head body 100 as shown in FIG.
In step 2, a difference in wall thickness between the face member 101 and the head main body 100 causes a step difference, and stress is concentrated on the welded or bonded portion 102, and this portion is likely to be damaged by repeated impacts with a ball. On the other hand, in the method of the present invention, as shown in FIG. 3, even if the thickness (t) of the head body 1 is smaller than the total thickness (t 0 ) of the face member 6, the head body 1 Since the thickness (t 1 ) of the peripheral edge of the opening is substantially the same as the thickness (t 0 ) of the peripheral edge of the face member 6, stress concentration does not occur in the welded or bonded portion 13 and the joint area And a fixing method having excellent impact resistance is achieved.

Is welded to the end surface 7 of the peripheral edge portion of the face member 6 at the joint portion 13, and the thickness t 1 of this portion is set to 2 mm or more and extends backward by the length a, and the thickness of the sole 3 thereafter is It is about half of the wall thickness t 1 . Further, the length a is 3 to 5
It is about mm. Furthermore, in this embodiment, the peripheral edge portion of the face member 6 is bent rearward of the face surface to bend the bent portion 6.
Forming A. A groove (shown by a chain line in FIG. 3) extending along the peripheral edge of the face member is provided between the bent portion 6A and the end surface 7 of the peripheral edge of the face member 6 so as to absorb the impact on the face surface. You can Also, the head body 1
It is preferable to gradually reduce the wall thickness from the region of the length a at the peripheral edge of the opening to the thin portion (thickness t) of the head body 1 to avoid stress concentration. Further, the welding of the joint portion 13 between the face member 6 and the head body 1 is performed from the outside of the head.

Bending of the face member by joining the faces to each other
Along the edge of the face member between the edge and the end face of the edge
An end face of the peripheral edge of the opening of the head body is provided with an extending groove.
Since the thickness of the end face of the bent portion of the wall thickness and the face member joining the end faces in substantially the same thickness, stress concentration does not occur in the joint, yet the impact bonding area is increased It has excellent properties. Further, since the end of the peripheral edge portion of the face member is bent rearward of the face surface and abuts against the peripheral edge portion of the opening of the head body, the stress of the joint portion generated by the hit ball is reduced. Further, from the area of a predetermined length at the peripheral edge of the opening of the head body to the thin portion of the head body.
The part up to the minute is the one where the wall thickness is gradually reduced.
Therefore, concentrated stress can be avoided .
