【発明の属する技術分野】本発明は、フェース中央部が
薄肉である高反発型のアイアン用ゴルフクラブヘッド
（以下「アイアンヘッド」）に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a highly resilient golf club head for an iron (hereinafter, referred to as "iron head") having a thin center portion of a face.
【０００２】[0002]

合も多い。2. Description of the Related Art Conventionally, a face portion is easily bent,
Iron heads with improved resilience are known. For this purpose, many inventions have been made, such as making the face thinner or using a material having a low elastic modulus for the face.
However, in these inventions, the strength of the face tends to be insufficient, and the countermeasures often require a large cost.

とが困難になる問題がある。On the other hand, there is also an invention in which the face is more easily bent by increasing the area of the thin portion of the face. For example, there is an invention described in Japanese Patent Application Laid-Open No. 2000-116822 in which the face is enlarged upward. But,
Enlarging the face upward has a problem that the center of gravity of the head becomes high and it is difficult to hit at a so-called sweet spot.

ラブヘッドである。The present invention provides: (1) a cavity-type or hollow-type iron head characterized in that the center of the sole is thinner than the toe side and the heel side of the sole. 2) The golf club head according to the above (1), wherein the thickness of the center portion of the sole is 5 mm or less. (3) The toe side portion of the sole and the heel side portion of the sole have a thickness of 5 mm or more. (2) The golf club head according to the above (2), wherein the thickness of the face is 2.5 mm or less, and the thickness of the face is 2.5 mm or less. From at least one of
The golf club head according to any one of (1) to (3), further including an overhang portion extending in a cavity direction.
【０００７】ソールのトウ側部及びヒール側部に比べ、

である。[0007] Compared to the toe side and the heel side of the sole,
If the center part of the sole is made thin, the face becomes more flexible, and at the same time, the rigidity required for the sole part is maintained.

方に延びるオーバーハング部を有する例でもある。FIG. 1 shows a first embodiment, and FIG. 2 shows a second embodiment. These are examples in which a face member is joined to a head main body, and only the head main body is shown. Further, these embodiments are also examples having an overhang portion extending upward from the rear of the sole portion.

さの意味である。As can be seen from FIG. 1, the central part 2 of the sole
-1 is provided with a concave portion, which is thinner than the toe side portion 2-2 and the heel side portion 2-3 of the sole. The thickness of each portion of the sole as referred to herein means a thickness from a surface of the sole facing the cavity to a surface in contact with the ground as shown in FIG.

確保される。In this manner, the restraint of the head body at the center of the face portion on the sole side is weakened, and the face is easily bent in the vertical direction. However, since the toe side portion 2-2 and the heel side portion 2-3 of the sole have a sufficient thickness, the rigidity of the entire head main body does not greatly decrease. Accordingly, the rigidity of the head as a whole against torsion and the like is ensured while improving the flexibility of the face portion.

拡大した効果もあり、より反発性の向上が期待できる。FIG. 2 shows an embodiment of the type in which the thin portion of the central portion 2-1 of the sole is formed in a groove shape and the groove extends to the back surface of the face member. Thereby, there is also an effect of enlarging a portion where the face portion is not in contact with the head body, that is, a thin portion of the face, and further improvement in resilience can be expected.
【００１２】以下に、各実施例におけるソール各部の肉
厚寸法を示す。The thickness of each part of the sole in each embodiment will be described below.

を大きくして、ヘッド全体の剛性を確保した。Embodiment 1 is made of a titanium alloy and has a lower modulus of elasticity than a general iron-based material. Therefore, to be smaller than the conventional wall thickness t c of the central portion of the sole, even while weakening the restraint on further face, the thickness of the wall thickness t t and the heel side of the toe side of the sole t h
To ensure the rigidity of the entire head.
