Description of the invention (4) Degree B is set within the range of 7 mm or more and 2 Omni or less. The face angle B is the distance from the axis C L of the shaft 2 (or the joint 4) to the front end 5 a1 (Leading Wedge) of the head of the face 5. The range of the aforementioned face angle B is larger than 0 to 6.5 mm of the golf club of the iron series. Therefore, even if the golf clubs of the iron series and the shot angle 0 are set to be the same, the angle at which the ball flies out becomes larger. For example, even if the shot angle 0 is set to the minimum of the iron series 値 19 ° or 2 2 °, you can also easily hit the ball. The range of the width A of the head is larger than the width of the head of the iron series by 15 to 25 mm. Therefore, even if the face angle B is larger than that of the iron series, the depth of the center of gravity G can be ensured, that is to say, it can ensure that the center of gravity G remains behind the face 5 (left side of FIG. 1), making the sweet spot (.sweet spot) will not be too narrow, it can be as easy as the iron series. Hit the ball in the right direction. On the other hand, the width A of the head is smaller than that of the wood head of 70 to 90 mm. In addition, the head 3 has a lightweight structure, so a material having a large specific gravity, such as high-strength steel (marage) (specific gravity 8. 0), can be used as the material for manufacturing the head 3 to strengthen the inertia shear force. This point> If compared with the wood club series of golf clubs, the golf clubs of the wood series in order to increase the size of the club head 'light weight; the stomach, to ensure headspeed, so use such as駄 (v

Titan) (specific gravity 4 · 5). As a result, not only the thickness of the head of the golf club becomes thin, which results in instability in strength, but also weakens its impact force and reduces the initial velocity of the ball. In addition, since it is within the scope of the present invention, different shot angles are provided. 0 ^ 州 州 (rNsTA ^ Wi; (210X 297 ^ #) " " — 419357 Λ7 ____ B7 V. Plural golf instructions (5) For clubs, a larger face angle B can be set with a larger impact angle 0. In addition, the relationship between the head width A and the face angle B is preferably larger on one side and larger on the other side. Also, if the head width A is set to a minimum 値 4 Omm, the face angle B is set to a minimum 値 7mm, and when the head width A is set to a maximum 値 60mm, the face angle B is When it is set to a maximum of 値 20 mm to adjust the relationship between the two, the variation range of the face angle B with respect to the head width A will be maintained within a range of 17.5% or more and 33.3% or less. Fan Lili, if you want to choose the Golf golf club according to the hitting distance, set the head width A to be within the range of 40 mm to 5 2 mm, and then it is best to be within this range. The stroke angle 0 and the face angle B are set to be smaller 値. At this time, it is best to set the stroke angle Θ below 19 °, and the face angle The degree B is set to 16 mm or less. On the other hand, if the golf club is to be selected based on the directional distance, it is best to set the head width A to a range of 56 mm to 60 mm, and then it is best to Within this range, set the striking angle 0 and the face angle B to a larger value. At this time, it is best to set the striking angle 0 to 25 ° or more, and the face angle B to 19_ 5mm or more = in the above. Head 3, sole width C, that is, when the distance from the LLL edge 5 a of the face 5 to the edge 6 a of the rear end of the sole 6 is set within the range of \ 30 mm to 40 mm, it is easier to swing In the head 3, the width A of the head and the angle B of the face can be set as described above, and the above-mentioned effect can be surely exerted.

For example, a weight 7 composed of manganese (Tungsten) (specific gravity 1 4 _ 0) is installed. In this way, a deeper and lower center of gravity G f can be formed * At the upper end of the head 3, a crown 8 having the same width as the diameter D of the joint 4 is provided. This crown 8 has a pair of ridge lines 8 a and 8 b extending substantially parallel to the shaft axis C L when the player stares at the head 3 when aiming at the shot (see FIG. 4). The face 5 is provided with a scoreline 9 for turning it when hitting the ball. The distance between these ends 9a, 9b and the edges 5b, 5c of the face 5 will gradually decrease downward along the center of the face 5. increase. With this configuration, from the perspective of the player, when the player is aiming to hit the ball, the face 5 will look smaller. Fig. 5 shows that the same size of the head 3 set in the above-mentioned setting range is overlapped with the head of the conventional wood series 1 0 0 (dashed line) and the head of the iron series 1 0 1 (hypothetical line). Icon. It can be clearly understood from this figure that the head 3 of this embodiment looks lighter than the head 1 0 0 of the wood series, and has a wider width A and a face angle B than the head 1 1 of the iron series. Both are large, that is to say, they have an intermediate character between the wood series and the iron series. In this embodiment, it is preferable that the shaft 2 is constituted by conventionally using reinforced synthetic resin such as carbon fiber. In particular, the fixed vibration number of the golf club for the entire shaft of the golf club 1 is preferably set to Set the material, shape, and size (such as thickness) of the shaft 2 in the range of 2 6 5 minutes and 2 8 5 minutes.
