るウッド型ゴルフクラブヘッドを要旨とする。To achieve the above object, the present invention relates to a wood type golf club head having a metal shell structure, which is located at a central portion of the sole surface in the width direction from a position spaced rearward from the back surface of the face constituting shell wall. A recess extending rearward and extending in the front-rear direction, which is open to the back face surface, is provided. The recess is formed in a parallel portion having a constant width or a substantially constant width on the front side and is continuously connected to the parallel portion on the rear side. A wood-type golf club head is characterized in that the width is gradually increased toward the rear and is formed in an opening portion opened to the back face surface.

定されるのがよい。In this case, as shown in FIG. 2, the recess has a length L of the parallel part in the range of 10 to 40 mm, a width B of the parallel part in the range of 8 to 30 mm, and a depth D. 5
It is preferable to set each in the range of mm to 1/2 of the head height H.

おいて設定される。More preferably, the recess is set such that the length L of the parallel part in the front-rear direction is in the range of 20 to 35 mm, the width B of the parallel part is in the range of 10 to 20 mm, and the depth D is in the range of 5 to 15 mm. To be done.

びが実現されるようになる。When the depth of the center of gravity, which is the distance from the face to the center of gravity, is increased, the sweet spot is widened accordingly. In order to utilize this property, in the wood-type club head having the above-described configuration, the front and rear portions of the sole face, which extend rearward from the position rearwardly separated from the rear face of the shell wall, are opened to the back face face at the center in the width direction. A recess extending in the direction is provided. As a result, the depth of the center of gravity is increased by the weight of the shell walls on both sides of the recess, and the sweet spot is widened. Therefore, the hit probability at the sweet spot is increased, the directionality is good, and a straight flight without slices or hooks is realized.

て、低重心となり、高弾道が実現される。In addition, as described above, a recess extending in the front-rear direction is provided at the center of the sole surface in the width direction and extends rearward from a position separated rearward from the back surface of the face-constituting shell wall and is open to the back face surface. The weight of the shell walls on both sides of the recess provides a low center of gravity and a high trajectory.

る。In particular, the recess has an opening whose width gradually increases toward the rear on the rear side thereof, so that the center of gravity is more effectively controlled by the weight of the shell walls on both sides of the opening. Deeper and lower center of gravity.

ない。Further, in particular, the recess is formed in a parallel portion having a constant width or a substantially constant width on the front side which is the face side, so that the shell walls on both sides sandwiching the parallel portion are arranged in the front-rear direction. The shell walls on both sides are concentrated and explosively transmit energy to the ball at the moment of hitting the ball, so that a so-called hammer effect is produced and a flight distance is increased. Moreover, since both side walls that sandwich the parallel portion are spaced from each other and are located at positions separated from the back surface of the face-constituting shell wall, the ball muscle does not become unstable.

ールは方向性良く飛距離大きく飛んでいく。Further, since the sole surface is provided with the recess opened to the back face surface, even if the sole surface is inadvertently grounded, the contact area is reduced by the recess and the swing-out is performed by opening the rear side. The low resistance at that time does not significantly hinder the swing-out property. In addition, since the recess has the parallel portion, the sole surface is thus grounded during the swinging process, and the parallel portion of the recess acts to guide the head straight. Therefore, even if the sole surface comes into contact with the ground due to a miss shot or the like as described above, the ball travels a great distance with good directionality.
【００１２】また、該リセスは、後部側が平行部に連な

る。Further, since the recess is formed as an open part in which the rear side is connected to the parallel part and the width is gradually increased, the intensive swing-out can be smoothly performed.

行部の幅Ｂが８〜３０ｍｍの範囲、深さＤが５ｍｍ〜ヘ
ッド高さＨの１／２の範囲において設定するのがよいと
するのは、次の理由による。In the above-mentioned structure, in the recess, the length L of the parallel portion in the front-rear direction is in the range of 10 to 40 mm, the width B of the parallel portion is in the range of 8 to 30 mm, and the depth D is 5 mm to the head height H. The reason why it is preferable to set in the range of 1/2 is as follows.

いて設定されるのがよい。That is, if the width B of the parallel portion becomes smaller than 8 mm, there is a high possibility that the parallel portion will be clogged with an object and the instability of the ball muscle at the time of hitting due to the hammer effect will increase. The tendency is likely to appear. Also,
When the width B of the parallel portion becomes larger than 30 mm, the shell wall on the bottom surface of the parallel portion becomes larger accordingly, which tends to raise the position of the center of gravity and tend to lower the high ballistic effect due to the low center of gravity. , The grounding stability during stance tends to deteriorate, and further changes in loft and instability in setting are likely to occur. For this reason, it is preferable that the width B of the recess parallel portion is set in the range of 10 to 20 mm.

なる傾向を生じる。このような理由から、リセス平行部
の深さＤは、特に５〜１５ｍｍの範囲において設定され
るのがよい。When the depth D of the parallel portion becomes smaller than 5 mm, the effect of increasing the weight of the side walls sandwiching the recess becomes insufficient, so that the sweet spot becomes wider due to the increase of the depth of the center of gravity, and the effect of lowering the center of gravity is reduced. It tends to be difficult to appear. Further, when the recess depth D exceeds 1/2 of the head height H and becomes large, this also tends to make it difficult for the low center of gravity effect to appear. For this reason, the depth D of the recess parallel portion is preferably set in the range of 5 to 15 mm.

よい。If the length L of the parallel portion is less than 10 mm, the hammer effect tends to be poor. Further, when the length L of the parallel portion becomes larger than 40 mm and becomes large, the opening portion becomes narrower in the front-rear direction, and the intentional swinging tends to be difficult. For this reason, the length L of the recess parallel part is
Is particularly preferably set in the range of 20 to 35 mm.
