【発明が解決しようとする課題】しかしながら、上述した従来技術では、単にフェース部材の背面に補強部材を配したにとどまり、ヘッドの重心位置やヘッド体積、重量を考慮してはいなかった。 [SUMMARY OF THE INVENTION However, in the prior art described above, simply stays arranged reinforcing members on the back of the face member, the center-of-gravity position and head volume of the head, were not taking into account the weight. そのため、ヘッドスピードの速いゴルファーにとっては、ボールの初速が上がり、 Therefore, for the fast-head speed golfer, it raises the initial velocity of the ball,
ヘッドの重心深さがフェース寄りにあるため、バックスピン量が減少することによって、適度なバックスピンとなり、飛距離を伸ばすことが可能となったが、一般のゴルファーは、打点がばらつき、ヘッドスピードも遅いため、飛距離を伸ばすことはむずかしかった。 Since the center of gravity depth of the head is in the face nearer by backspin amount decreases, it is appropriate backspin, although it is possible to extend the distance, ordinary golfer, variation RBI, head speed slow since, it has been difficult to extend the distance as well. 一般のゴルファーにとっては、ヘッド体積を大きくするとともに重心を深くすることによって、ヘッドの重心軸周りの慣性モーメントを大きくし、スイートエリアの拡大を図るとともに、重心を深くしバックスピン量を増やすことによって、ボールの揚力を高め、ボールを上がり易くし、ボール初速を上げる効果と合わせて、飛距離を伸ばすことができる。 For general golfers, by deepening the centroid with a larger head volume, to increase the moment of inertia about the central axis of the head, strive to expand the sweet area, by increasing the amount of backspin deep center of gravity , to increase the lift of the ball, to facilitate up the ball, together with the effect of raising the ball initial velocity, it is possible to extend the distance.

【0004】そこで、本発明は、フェース面のボールの反発を上げるとともに、一般のゴルファーでも飛距離を伸ばすことのできるゴルフクラブヘッドを提供することを目的とする。 [0004] It is an object of the present invention, as well as increase the rebound of the ball of the face surface, an object of the present invention is to provide a golf club head that can extend the distance in general of golfers.

【発明の実施の形態】以下に、この発明の好適な実施例を図面を参照にして説明する。 DETAILED DESCRIPTION OF THE INVENTION Hereinafter, will be described with the preferred embodiments with reference to the drawings of the present invention.

【0007】図1に示す実施例において、ゴルフクラブのヘッド本体部1にフェース開口部2を設け、このフェース開口部2にフェース部材3を溶接によって固着する。 [0007] In the embodiment shown in FIG. 1, the face opening 2 provided in the head main body portion 1 of the golf club, it is secured by welding a face member 3 to the face opening 2. この溶接部を符号M 1で示す。 It shows the welding portion by symbol M 1. フェース部材3の背面には補強部材4を溶接してある。 On the back of the face member 3 are welded to the reinforcing member 4. この補強部材4は、 The reinforcing member 4,
厚さ0.8〜2.5mm、上下端4A,4Bの夫々の幅を15〜40mmとし、これら上下端4A,4Bのみをフェース部材3の背面に当接し溶接してある。 The thickness 0.8~2.5Mm, upper and lower ends 4A, the width of each of 4B and 15 to 40 mm, the upper and lower ends 4A, are then abuts welded only to the back of the face member 3 4B. この補強部材4とフェース部材3との溶接個所を符号M 2で示す。 It shows the welds between the reinforcing member 4 and the face member 3 by reference numeral M 2. この補強部材4はフェース部材3のフェースセンターを含む位置に設けてある。 The reinforcing member 4 is provided at a position including the face center of the face member 3.

【0008】前記補強部材4の中心部の幅Lは20mm [0008] the width L of the central portion of the reinforcing member 4 is 20mm
程度とした。 It was the degree. この中心部の幅Lが15mm未満とすると、細くなりすぎて補強効果が少なくなり、フェース部材3の強度を持たせるためにフェース部材3の厚みを厚くする必要が生ずる。 If the width L of the central portion is less than 15 mm, the reinforcing effect becomes too thin is reduced, need arises to increase the thickness of the face member 3 in order to provide the strength of the face member 3. また、フェース部材3の厚みを厚くしてしまうと、反発性能が上がらなくなる恐れがある。 Further, when thus increasing the thickness of the face member 3, the resilience performance may become no longer rise. なおまた、中心部の幅Lを40mm以上とした場合には、補強部材4の質量及びそれを溶接する質量が付加され、重心位置がフェース寄りになり、一般ゴルファーにとってはヘッドの重心軸周りの慣性モーメントが小さくなったり、コントロールしにくいクラブとなってしまう恐れがある。 Note also, in the case where the width L of the center was above 40mm is added mass of welding mass and it reinforcement member 4, the center of gravity position becomes the face closer, around the central axis of the head for the general golfers moment of inertia or smaller, there is a fear that a control difficult club. また、補強部材4の厚さを薄くしすぎると、補強効果が少なくなり、また溶接が難しくなる。 Further, an excessively small thickness of the reinforcing member 4, the reinforcing effect is reduced, also the welding becomes difficult. 反対に補強部材4の厚さを厚くしすぎると、重心位置がフェース寄りになり好ましくない。 If too thick a thickness of the reinforcing member 4 in the opposite, center of gravity undesirably the face closer. したがって、補強部材4は幅15〜40mm、好ましくは20〜30mm、厚さ0.8〜2.5mm、好ましくは1.2〜2.0mm Accordingly, the reinforcing member 4 has a width 15 to 40 mm, preferably 20 to 30 mm, thickness 0.8~2.5Mm, preferably 1.2~2.0mm
