It has a peripheral wall surface 322, and a decorative member 7 is arranged as described later. The recess 30 is arranged below the deepest portion of the insertion hole 41 of the hosel portion 4 in the reference state.

本実施形態において、フェース部１とクラウン部２、及びフェース部１とソール部３との境界は、次のように定義することができる。この点について、図５を参照しつつ説明する。すなわち、両者の間に稜線が形成されている場合には、これが境界となる。一方、明確な稜線が形成されていない場合には、図５Ａに示されるように、ヘッド重心ＧとスイートスポットＳＳとを結ぶ直線Ｎを含む各断面Ｅ１、Ｅ２、Ｅ３…において、図５Ｂに示されるように、フェース外面輪郭線Ｌｆの曲率半径ｒがスイートスポット側からフェース外側に向かって初めて２００ｍｍとなる位置Ｐｅがフェース部１の周縁となり、これがクラウン部２またはソール部３との境界として定義される。なお、スイートスポットＳＳとは、ヘッド重心Ｇを通るフェース面の法線（直線Ｎ）とこのフェース面との交点である。 In the present embodiment, the boundary between the face portion 1 and the crown portion 2 and the face portion 1 and the sole portion 3 can be defined as follows. This point will be described with reference to FIG. That is, when a ridgeline is formed between the two, this is the boundary. On the other hand, when a clear ridgeline is not formed, as shown in FIG. 5A, it is shown in FIG. 5B in each cross section E1, E2, E3 ... The position Pe where the radius of curvature r of the outer surface contour line Lf of the face becomes 200 mm for the first time from the sweet spot side toward the outside of the face becomes the peripheral edge of the face portion 1, and this is defined as the boundary with the crown portion 2 or the sole portion 3. Will be done. The sweet spot SS is an intersection of the normal line (straight line N) of the face surface passing through the center of gravity G of the head and the face surface.

また、本実施形態において、クラウン部２とソール部３との境界は次のように定義することができる。すなわち、クラウン部２とソール部３との間に稜線が形成されている場合には、これが境界となる。一方、これらの間に明確な稜線が形成されていない場合には、ヘッドを基準状態に設置し、これをヘッド１０の重心の真上から見たときの輪郭が境界となる。 Further, in the present embodiment, the boundary between the crown portion 2 and the sole portion 3 can be defined as follows. That is, when a ridge line is formed between the crown portion 2 and the sole portion 3, this becomes a boundary. On the other hand, when a clear ridge line is not formed between them, the head is installed in a reference state, and the contour when viewed from directly above the center of gravity of the head 10 is the boundary.

また、ヘッド１０は、例えば、比重がほぼ４．３～４．５程度のチタン合金（Ｔｉ－６Ａｌ－４Ｖ、Ｔｉ－８Ａｌ－１Ｍｏ－１Ｖ等）で形成することができる。また、チタン合金以外にも、例えばステンレス鋼、マレージング鋼、アルミニウム合金、マグネシウム合金、またはアモルファス合金などの中から１種または２種以上を用いて形成することもできる。 Further, the head 10 can be formed of, for example, a titanium alloy (Ti-6Al-4V, Ti-8Al-1Mo-1V, etc.) having a specific gravity of about 4.3 to 4.5. Further, in addition to the titanium alloy, it can be formed by using one or more of, for example, stainless steel, maraging steel, aluminum alloy, magnesium alloy, amorphous alloy and the like.

また、このゴルフクラブヘッド１０の体積は、例えば、９０ｃｍ3以上、４６０ｃｍ3以下が望ましい。 Further, the volume of the golf club head 10 is preferably, for example, 90 cm 3 or more and 460 cm 3 or less.

＜２．ウエイト部材＞
続いて、ウエイト部材６について、図６を参照しつつ説明する。図６は、装飾部材７及びウエイト部材６を取り付けた状態のソール部３の凹部３０の断面図である。図６に示すように、このウエイト部材６は、円柱状（あるいは円板状）に形成されており、上述したソール部３の凹部３０の第１収容部３１に収容される。そのため、ウエイト部材６の外形は、第１収容部３１に収容可能な大きさに形成されている。そして、ウエイト部材６は、接着剤などで第１収容部３１の底面３１１または周壁面３１２に固定することができる。但し、ネジ止めなどの他の方法で固定することもできる。ウエイト部材６を形成する材料は、特には限定されないが、例えば、アルミニウム、ステンレス等の金属や、Ｗ、Ｎｉ及びＦｅを含むタングステン・ニッケル・鉄合金等の合金、あるいは樹脂材料を用いることができる。なお、ウエイト部材６は、それぞれ異なる重さのものを複数準備しておくことができ、複数種のうちのいずれかを用いることで、ヘッド１０の重量や重心位置を変更することができる。 <2. Weight member ＞
Subsequently, the weight member 6 will be described with reference to FIG. FIG. 6 is a cross-sectional view of the recess 30 of the sole portion 3 in a state where the decorative member 7 and the weight member 6 are attached. As shown in FIG. 6, the weight member 6 is formed in a columnar shape (or a disk shape), and is housed in the first storage portion 31 of the recess 30 of the sole portion 3 described above. Therefore, the outer shape of the weight member 6 is formed to a size that can be accommodated in the first accommodating portion 31. Then, the weight member 6 can be fixed to the bottom surface 311 or the peripheral wall surface 312 of the first accommodating portion 31 with an adhesive or the like. However, it can also be fixed by other methods such as screwing. The material forming the weight member 6 is not particularly limited, and for example, a metal such as aluminum or stainless steel, an alloy such as tungsten, nickel, or iron alloy containing W, Ni, and Fe, or a resin material can be used. .. A plurality of weight members 6 having different weights can be prepared, and the weight and the position of the center of gravity of the head 10 can be changed by using any one of the plurality of types.

＜３．装飾部材＞
次に、装飾部材７について説明する。図６に示すように、装飾部材７は、円板状に形成されており、上述したソール部３に凹部３０の第２収容部３２に収容される。そのため、装飾部材７の外形は、第２収容部３２に収容可能な大きさに形成されているが、ウエイト部材６を覆うために、ウエイト部材６よりも大きい外径を有している。このとき、装飾部材７とウエイト部材６とは、円板の中心がほぼ一致した状態で、凹部３０に配置される。また、装飾部材７において、ウエイト部材６とは反対側の面、つまり外部に露出する面には、例えば、図７に示すような装飾が施されている。装飾部材７を形成する材料は、特には限定されないが、例えば、アルミニウム、ステンレス等の金属や、あるいは樹脂材料用いることができる。装飾部材７の固定方法は、特には限定されないが、例えば、第２収容部３２の周壁面３２２に雌ネジを形成し、装飾部材７の外周面に雄ネジを形成する。そして、装飾部材７を第２収容部３２にネジ止めすることで、装飾部材７を第２収容部３２に固定することができる。その他、装飾部材７を第２収容部３２の底面３２１にネジ止めや接着剤により、固定することもできる。 <3. Decorative material ＞
Next, the decorative member 7 will be described. As shown in FIG. 6, the decorative member 7 is formed in a disk shape, and is accommodated in the second accommodating portion 32 of the recess 30 in the sole portion 3 described above. Therefore, the outer shape of the decorative member 7 is formed to a size that can be accommodated in the second accommodating portion 32, but has an outer diameter larger than that of the weight member 6 in order to cover the weight member 6. At this time, the decorative member 7 and the weight member 6 are arranged in the recess 30 in a state where the centers of the discs are substantially aligned with each other. Further, in the decorative member 7, the surface opposite to the weight member 6, that is, the surface exposed to the outside, is decorated as shown in FIG. 7, for example. The material forming the decorative member 7 is not particularly limited, but for example, a metal such as aluminum or stainless steel, or a resin material can be used. The method for fixing the decorative member 7 is not particularly limited, but for example, a female screw is formed on the peripheral wall surface 322 of the second accommodating portion 32, and a male screw is formed on the outer peripheral surface of the decorative member 7. Then, by screwing the decorative member 7 to the second accommodating portion 32, the decorative member 7 can be fixed to the second accommodating portion 32. In addition, the decorative member 7 can be fixed to the bottom surface 321 of the second accommodating portion 32 by screwing or an adhesive.

＜４．ゴルフクラブヘッドの組立構造＞
本実施形態に係るゴルフクラブヘッド１０は、図４に示すように、クラウン部２及びソール部３を有するヘッド本体１０１と、フェース部１及びその周縁から延びる周縁部１５を有するカップ状に形成されたフェース用部材１０２と、を組み立てることで構成される。このヘッド本体１０１は、クラウン部２及びソール部３で囲まれた開口１８を有し、この開口１８を塞ぐようにフェース用部材１０２が取り付けられる。すなわち、フェース用部材１０２の周縁部１５の端面が、ヘッド本体１０１の開口１８の端面と突き合わされ、これらが、溶接によって接合される（いわゆるカップフェース構造）。そして、フェース用部材１０２は、ヘッド本体１０１の開口１８の縁部に取付けられることで、ヘッド本体１０１と一体化され、これによって、フェース用部材１０２の周縁部１５は、ヘッド１０のクラウン部２及びソール部３の一部として機能する。 <4. Golf club head assembly structure>
As shown in FIG. 4, the golf club head 10 according to the present embodiment is formed in a cup shape having a head main body 101 having a crown portion 2 and a sole portion 3 and a peripheral edge portion 15 extending from the face portion 1 and its peripheral edge. It is configured by assembling the face member 102 and the face member 102. The head body 101 has an opening 18 surrounded by a crown portion 2 and a sole portion 3, and a face member 102 is attached so as to close the opening 18. That is, the end face of the peripheral edge portion 15 of the face member 102 is abutted against the end face of the opening 18 of the head main body 101, and these are joined by welding (so-called cup face structure). Then, the face member 102 is integrated with the head body 101 by being attached to the edge portion of the opening 18 of the head body 101, whereby the peripheral edge portion 15 of the face member 102 is the crown portion 2 of the head 10. And functions as a part of the sole portion 3.

したがって、フェース用部材１０２の周縁部１５がヘッド本体１０１に取付けられることで一体的に形成される面が、ヘッド１０のクラウン部２及びソール部３を構成する。そのため、厳密には、ヘッド本体１０１のクラウン部２及びソール部３は、ヘッド１０のクラウン部２及びソール部３の一部ではあるが、本明細書では、これらを区別することなく、ヘッド本体１０１の各部も、単にクラウン部２、ソール部３と称することがある。 Therefore, the surface integrally formed by attaching the peripheral edge portion 15 of the face member 102 to the head main body 101 constitutes the crown portion 2 and the sole portion 3 of the head 10. Therefore, strictly speaking, the crown portion 2 and the sole portion 3 of the head main body 101 are a part of the crown portion 2 and the sole portion 3 of the head 10, but in the present specification, these are not distinguished and the head main body is not distinguished. Each part of 101 may also be simply referred to as a crown part 2 and a sole part 3.

＜５．ゴルフクラブヘッドの製造方法＞
次に、上記のゴルフクラブヘッドの製造方法の一例について説明する。まず、上述したヘッド本体１０１とフェース用部材１０２とを準備する。このようなヘッド本体１０１及びフェース用部材１０２は、種々の方法で作製することができる。例えば、ヘッド本体１０１は、公知のロストワックス精密鋳造法などの鋳造によって製造することができる。また、フェース用部材１０２は、例えば、鍛造製法や、平板のプレス加工、鋳造等により製造することができる。また、このとき用いるフェース用部材１０２の加工前の平板は、圧延方向が、フェース部１のトゥ側の上部からヒール側の下部に向かう方向とほぼ一致するように加工される。 <5. How to make a golf club head ＞
Next, an example of the above-mentioned method for manufacturing a golf club head will be described. First, the head body 101 and the face member 102 described above are prepared. Such a head body 101 and a face member 102 can be manufactured by various methods. For example, the head body 101 can be manufactured by casting such as a known lost wax precision casting method. Further, the face member 102 can be manufactured by, for example, a forging method, stamping of a flat plate, casting, or the like. Further, the flat plate before processing of the face member 102 used at this time is processed so that the rolling direction substantially coincides with the direction from the upper portion on the toe side of the face portion 1 to the lower portion on the heel side.

そして、これらを、例えば、溶接（ＴＩＧ（タングステン－不活性ガス）溶接、プラズマ溶接、レーザー溶接、ロウ付けなど）により接合した後、所定の塗装を施すと、ゴルフクラブヘッドが完成する。 Then, after joining these by, for example, welding (TIG (tungsten-inert gas) welding, plasma welding, laser welding, brazing, etc.), a predetermined coating is applied to complete the golf club head.

その後、ヘッドを所定の重量にするため、あるいは重心の位置を調整するために、複数のウエイト部材６から適切なものを適宜選択した後、ウエイト部材６を凹部３０の第１収容部３１に固定する。例えば、厚みが異なるウエイト部材６を配置した場合には、ヘッドの重心位置を調整することもできる。続いて、ウエイト部材６を覆うように、第２収容部３２に装飾部材７を固定する。こうして、本実施形態に係るゴルフクラブヘッドが完成する。 After that, in order to make the head a predetermined weight or adjust the position of the center of gravity, an appropriate weight member 6 is appropriately selected from the plurality of weight members 6, and then the weight member 6 is fixed to the first accommodating portion 31 of the recess 30. do. For example, when the weight members 6 having different thicknesses are arranged, the position of the center of gravity of the head can be adjusted. Subsequently, the decorative member 7 is fixed to the second accommodating portion 32 so as to cover the weight member 6. In this way, the golf club head according to the present embodiment is completed.

(2) 装飾を施されていないウエイト部材６は、装飾部材７によって覆われ、外部から視認できないように構成されている。そのため、ウエイト部材６については、意匠性を勘案することなく、形状や重量を自由に変更することができる。したがって、ヘッドの重量調整の自由度を向上することができる。また、重量調整のため、例えば、複数種のウエイト部材６を準備する際、装飾用の加工を施す必要がないため、コストを低減することができる。 (2) The undecorated weight member 6 is covered with the decorative member 7 so as not to be visible from the outside. Therefore, the shape and weight of the weight member 6 can be freely changed without considering the design. Therefore, the degree of freedom in adjusting the weight of the head can be improved. Further, for weight adjustment, for example, when preparing a plurality of types of weight members 6, it is not necessary to perform decorative processing, so that the cost can be reduced.

(3) 装飾部材７は、凹部３０に対し、取り外しできないように固定することもできるし、取り外し可能に固定することもできる。取り外し可能に構成すれば、種々の装飾部材７を取り付けることができ、ヘッドの外観を変更することができる。 (3) The decorative member 7 can be fixed to the recess 30 so as not to be removable, or can be fixed to the recess 30 so as to be removable. If it is configured to be removable, various decorative members 7 can be attached and the appearance of the head can be changed.

(4) ウエイト部材６も、凹部３０に対し、取り外しできないように固定することもできるし、取り外し可能に固定することもできる。取り外し可能に構成すれば、大きさや形状の異なるウエイト部材６を第１収容部３１に取り付けることができるため、ヘッドの製造後に、ユーザの要求に応じて、ヘッドの重量や重心を調整することができる。この場合、装飾部材７も取り外し可能に構成する必要がある。ウエイト部材６を取り外しできないようにする場合には、製造時に、ヘッドを所定の重量にするため、あるいは重心の位置を調整した上で、ウエイト部材６の固定を行う。 (4) The weight member 6 can also be fixed to the recess 30 so as not to be removable, or can be fixed to the recess 30 so as to be removable. If it is configured to be removable, the weight member 6 having a different size and shape can be attached to the first accommodating portion 31, so that the weight and the center of gravity of the head can be adjusted according to the user's request after the head is manufactured. can. In this case, the decorative member 7 also needs to be removable. When the weight member 6 cannot be removed, the weight member 6 is fixed in order to make the head a predetermined weight or after adjusting the position of the center of gravity at the time of manufacturing.

(5) ウエイト部材６が収容される凹部３０は、ホーゼル部４の挿入孔４１の最深部よりも下方に配置されている。そのため、例えば、ホーゼル部４の挿入孔４１の最深部にウエイト部材を配置する場合に比べ、ヘッドの重心を低くすることができる。 (5) The recess 30 in which the weight member 6 is housed is arranged below the deepest portion of the insertion hole 41 of the hosel portion 4. Therefore, for example, the center of gravity of the head can be lowered as compared with the case where the weight member is arranged in the deepest portion of the insertion hole 41 of the hosel portion 4.
