Description

  The present invention relates to a wood club head, a wood club, and a wood club attachment. More specifically, a wood club head and wood club that has a ventilation guide body that can be attached to and detached from a wood club that conforms to the current equipment rules, and that can improve the controllability of the club when installed, and a wood that conforms to the current equipment regulations. The present invention relates to an attachment for a wood club that can be attached to and detached from a club and can be a ventilation guide body at the time of attachment to improve the controllability of the club.

  In recent years, the size of wood club heads has been increasing with the evolution of materials and processing techniques. Such wood clubs are popular with ordinary players because they are easy to hit and can be expected to improve flight distance. As such a large wood club, for example, a golf club head described in Patent Document 1 has been proposed.

  As shown in FIG. 6, the golf club head 9 described in Patent Document 1 (hereinafter referred to as “club head 9”) has a metal hollow shell structure with a head volume of 270 ml or more, and has a head center-of-gravity angle of 30. It is set in the range of 5 to 35 °. According to the club head 9, the return of the head during swinging is improved, the slice is suppressed, the flight distance can be increased, and the average golfer is easy to use.

JP 2002-113135 A

  By the way, when a wood club provided with the club head 9 described in Patent Document 1 is swung, the club head rises during the swing, and the trajectory actually passes above the trajectory of the club head imaged by the swinging person himself / herself. It may become. When swinging in such a trajectory, the hit ball tends to become a so-called top (a phenomenon of hitting the ball head). This top is especially likely to occur on driver shots that swing greatly.

  The cause of this is not clear, but the crown 91 (the upper part of the club head 9) of the club head 9 swells upward, and the sole 92 (the lower part of the club head 9) has an asymmetrical shape and has a volume. Instead, since it is lightweight, it is presumed that lift is generated due to the difference in the flow velocity of the air flowing on the surface as in the case of a so-called airfoil member.

  The lift generated here can control the club by swinging with a force if it is a relatively strong person such as a young or middle-aged player, but the elderly and women with weak muscles can control the club. Control may not work.

  The club head 9 cannot solve such a phenomenon, and the same phenomenon occurs in a lightweight hollow large driver manufactured by others.

  Therefore, the present inventor has considered that the occurrence of the lift may be eliminated or suppressed by making the flow velocity of the air flowing through the upper and lower surfaces of the club the same or substantially the same. As a means for eliminating or suppressing the generation of lift, for example, it is conceivable to make a structure in which an air inlet is provided in a club face of a wood club and the air is discharged to the back face side. However, such clubs cannot be used for regular games because they violate the current golf equipment rules, and wood clubs are generally expensive among golf clubs, and their use is restricted even if they are purchased with great care. So cost performance is bad.

  The present invention was devised in view of the above points, and includes a ventilation guide body that can be attached to and detached from a wood club that conforms to the current equipment rules, and can improve the controllability of the club during attachment. The present invention relates to an attachment for a wood club that can be attached to and detached from a head, a wood club, and a wood club that conforms to the current equipment rules, and that can be used as a ventilation guide when attached to improve the controllability of the club.

  In order to achieve the above object, the wood club head of the present invention is formed in a belt plate shape having a required length and a head main body having a hollow shell structure in which a part or all of the members constituting the outer shell are thin. And a required number of spacers provided on one end of the rectifying plate, and a required number of spacers provided with attachment portions that can be attached to and detached from the crown surface of the head body. A ventilation guide attached to the surface of the crown so that the longitudinal direction of the current plate is parallel or substantially parallel to the direction connecting the heel side and the toe side of the crown.

  Here, a flow path through which air can flow from the face surface side of the head body toward the back face side is formed between the crown surface and the rectifying plate by the ventilation guide body attached to the crown surface. Normally, the flow velocity of air flowing through the crown surface is faster than the flow velocity of air flowing through the lower surface of the head body (hereinafter referred to as the “sole surface”). By passing, the flow of smooth air is obstructed, and the flow velocity of the air flowing through the crown surface and the sole surface, which are the upper and lower surfaces of the head body, is the same or nearly the same, and the lift generated in the wood club head during the swing Can be eliminated or suppressed.

  The head body is an attachment target of the ventilation guide body. The head main body has a thin hollow shell structure in which part or all of the members constituting the outer shell are thin, and thus the head main body is light in weight.

  The rectifying plate closes the upper part of the flow passage formed by the ventilation guide body, and can change the flow direction of the air flowing into the flow passage and hitting the rectifying plate into an irregular flow. In addition, the spacer can block the lateral side of the flow path formed by the ventilation guide body and can maintain the opening height of the flow path.

  In addition, when the length of the current plate in the longitudinal direction is in the range of 75 mm to 100 mm, it is possible to suitably eliminate or suppress the generation of lift generated in the wood club head during the swing.

  When the length of the current plate in the longitudinal direction is less than 75 mm, the air resistance generated from the ventilation guide body is weakened, and the generation of lift generated in the wood club head at the time of swinging tends not to be eliminated or suppressed. is there. Further, when the length of the current plate in the longitudinal direction exceeds 100 mm, the effect of eliminating or suppressing the lift generated in the wood club head at the time of swinging is peaked, while the air resistance generated by the ventilation guide body causes the swing. There is a tendency to reduce the speed.

  In addition, when the length of the current plate in the short direction is within a range of 5 mm to 30 mm, it is possible to suitably eliminate or suppress the generation of lift generated in the wood club head during a swing.

  When the length of the current plate in the short direction is less than 5 mm, the air resistance generated from the ventilation guide body is weakened, and the generation of lift generated in the wood club head at the time of swing cannot be eliminated or suppressed. On the other hand, it tends to drop off or break due to wind pressure during swing. In addition, when the length of the current plate in the short direction exceeds 30 mm, the effect of eliminating or suppressing the lift generated in the wood club head at the time of swinging is peaked, while the air resistance generated by the ventilation guide body There is a tendency to reduce the swing speed.

  In addition, when the protruding length of the spacer is in the range of 0.9 mm to 1.5 mm, this protruding length is the opening height of the flow passage formed by the ventilation guide body, and within that range. For example, the generation of lift generated in the wood club head during a swing can be preferably eliminated or suppressed.

  If the protrusion length of the spacer is less than 0.9 mm, the entrance of the flow passage formed by the ventilation guide body is too small to allow air to flow in, and the air flowing through the crown surface only exceeds the ventilation guide body. Therefore, there is a tendency that the flow velocity does not decrease, or the air flowing over the crown upper surface is greatly disturbed and the trajectory of the wood club head during the swing tends to become unstable. On the other hand, when the protrusion length of the spacer exceeds 1.5 mm, the entrance of the flow passage is too large and a large amount of air flows into the so-called through state. There is a tendency to be difficult to eliminate or suppress. In addition, there is a tendency that the swing speed is reduced by the air resistance generated by the ventilation guide body.

  In order to achieve the above object, a wood club head according to the present invention can be attached to and detached from a head body having a hollow shell structure in which part or all of the members constituting the outer shell are thin, and a crown surface of the head body. A belt-plate-shaped ventilation guide body having a required length that is attached and forms a gap along the direction connecting the heel side and the toe side of the crown with the crown surface.

  Here, due to the ventilation guide body attached to the crown surface, a gap (flow passage) through which air can flow from the face surface side of the head body toward the back face side is formed between the crown surface and the ventilation guide body. It is formed. The air flowing through the crown surface passes through the formed gap, so that the smooth air flow is hindered, and the flow velocity of the air flowing through the crown surface, which is the upper and lower surfaces of the head body, and the sole surface is the same or almost the same. Thus, it is possible to eliminate or suppress the generation of lift that occurs in the wood club head during a swing.

  The head body is an attachment target of the ventilation guide body. The head main body has a thin hollow shell structure in which part or all of the members constituting the outer shell are thin, and thus the head main body is light in weight.

  The ventilation guide body closes the upper side and the side of the gap formed by the ventilation guide body, can change the direction of the air flow flowing into the gap and hitting the current plate to an irregular flow, and The opening height of the gap can be maintained.

  In order to achieve the above object, a wood club of the present invention includes a shaft having a grip on one end side, and a hollow shell attached to the other end side of the shaft, and a part or all of the members constituting the outer shell are thin. A head body that is a body structure, a rectifying plate formed in a strip shape with a required length, and protruding on one surface of the rectifying plate, and attached to and detached from the crown surface of the head body at the tip of the protruding portion And the required number of spacers provided with possible attachments, and the crown surface is attached so that the longitudinal direction of the current plate is parallel or substantially parallel to the direction connecting the heel side and the toe side of the crown. And a wood club head having a worn ventilation guide body.

  Here, a flow path through which air can flow from the face surface side of the head body toward the back face side is formed between the crown surface and the rectifying plate by the ventilation guide body attached to the crown surface. The air flowing through the crown surface passes through the formed flow passage, so that the smooth air flow is inhibited, and the flow velocity of the air flowing through the crown surface and the sole surface, which is the upper and lower surfaces of the head body, is the same or almost It becomes the same, and generation | occurrence | production of the lift which arises in the wood club head at the time of a swing can be eliminated or suppressed.

  The shaft has a grip gripped by the user on one end side, and the wood club head is attached to the other end side, whereby the force caused by the user's swing can be transmitted to the wood club head.

  The head body is an attachment target of the ventilation guide body. The head main body has a thin hollow shell structure in which part or all of the members constituting the outer shell are thin, and thus the head main body is light in weight.

  The rectifying plate closes the upper part of the flow passage formed by the ventilation guide body, and can change the flow direction of the air flowing into the flow passage and hitting the rectifying plate into an irregular flow. In addition, the spacer can block the lateral side of the flow path formed by the ventilation guide body and can maintain the opening height of the flow path.

  In order to achieve the above object, the attachment for a wood club of the present invention has a rectifying plate formed in a strip shape of a required length, and protrudes on one surface of the rectifying plate, and the tip of the protruding portion is attached. And a required number of spacers having a structure that can be attached to and detached from the wearing target part.

  Here, the attachment for the wood club constitutes a ventilation guide body when attached to the crown surface of the wood club head, for example, and the face side of the wood club head between the crown surface of the wood club head and the current plate A flow passage through which air can flow from the back face side is formed. When air flowing through the crown surface passes through this formed flow passage, smooth air flow is hindered, and the flow velocity of air flowing through the crown surface and sole surface is the same or nearly the same, It is possible to eliminate or suppress the occurrence of lift generated in the wood club head.

  The rectifying plate closes the upper part of the flow passage formed when the attachment for the wood club is attached to the crown surface of the wood club head, for example, and flows into the flow passage so that the air flow hits the rectifying plate. The direction can be changed to an irregular flow.

  For example, the spacer can be attached to the crown surface of the wood club that is the attachment target portion of the spacer, and the lateral direction of the flow path formed by the attachment for the wood club and the crown surface after the attachment is attached. It can block | close and can maintain the opening height of a flow path. In addition, since the tip of the spacer is detachably attached to the attachment target part, for example, when participating in a formal game, it can be easily removed, and the attached wood club can be removed from the current equipment rules. Can be returned to the one that fits.

According to the wood club head of the present invention, the ventilation guide body that can be attached to and detached from the wood club conforming to the current equipment rules is provided, and the controllability of the club can be improved during attachment.
Further, according to the wood club of the present invention, the ventilation guide body that can be attached to and detached from the wood club conforming to the current equipment rules is provided, and the controllability of the club can be improved at the time of attachment.
Furthermore, according to the attachment for a wood club according to the present invention, it can be attached to and detached from a wood club that conforms to the current equipment rules, and when attached, it becomes a ventilation guide body and can improve the controllability of the club.

It is the perspective view which showed the wood club of this invention and abbreviate | omitted the shaft intermediate part. The attachment for wood clubs of this invention is shown, (a) is a perspective view, (b) is a bottom view. It is side view explanatory drawing showing the enlarged view of the head part of the wood club of FIG. 1, and the attachment part of a ventilation guide body. It is front view explanatory drawing which showed the head part of the wood club of FIG. FIG. 2 is a side view explanatory view showing an enlarged view of a head portion in which a flow of air on the surface at the time of swinging the wood club of FIG. 1 is indicated by an arrow and a ventilation guide body showing a flow of inflowing air. It is the longitudinal cross-sectional view which showed the wood club head of patent document 1.

  The embodiment of the present invention will be described in more detail with reference to FIGS. In addition, the code | symbol in each figure is attached | subjected within the range which reduces complexity and makes it easy to understand. The “ventilation guide body” in the present embodiment is equivalent to the “wood club attachment”, and the “ventilation guide body” separated from the head is the “wood club attachment”.

  The wood club 1 includes a shaft 2 having a required length and a wood club head 3 attached to the other end of the shaft 2. The shaft 2 has a grip 21 on one end side (see FIG. 1). The material forming the shaft 2 is not particularly limited. However, carbon fiber, fiber reinforced composite materials such as glass fiber, metal materials such as stainless steel, aluminum alloy, titanium alloy, etc., wood such as hickory Etc. are preferably used.

  The wood club head 3 includes a head body 30, a crown 31 that is an upper surface of the head body 30, a sole 32 that is a lower surface of the head body 30, a face 33 that is a striking surface, and a hosel that is an attachment portion of the shaft 2. 34. Of the head main body 30, the portion provided with the hosel 34 is a heel, the opposite direction is a toe, and the opposite side of the face 33 is a back face.

  The head body 30 is made of metal and has a hollow shell structure constituted by a thin outer shell. In the head body 30, the member constituting the outer shell may be not only a metal but also carbon fiber, synthetic resin, or a combination thereof. For example, if the other part is a lightweight material such as carbon fiber, only a part of the member constituting the outer shell is thin, and the other part except the part has a certain thickness. It may be a structure.

  A ventilation guide body 4 is attached to the surface of the crown 31 of the head body 30. The ventilation guide body 4 is composed of a rectifying plate 41 formed of a thin strip having flexibility and having a required length, and a plurality of spacers 42 depending on the lower surface portion of the rectifying plate 41. As described above, when the wood club attachment 4 shown in FIG. 2 is attached to the crown 31, the head 3 after the attachment becomes the ventilation guide body 4.

  In addition, an adhesive portion 421 is provided at the tip of the spacer 42, and has a required peel adhesive strength that does not easily peel off by wind pressure due to swing speed when attached to the surface of the crown 31. The adhesive portion 421 corresponds to the “attachment portion” described above.

  The ventilation guide body 4 is arranged such that the current plate 41 is parallel or substantially parallel to the longitudinal direction of the current guide plate 41 and the direction connecting the heel side and the toe side of the crown 31. Further, the ventilation guide body 4 is attached such that the longitudinal edge portion of the rectifying plate 41 on the face 33 side is 10 mm away from the upper edge of the face 33 toward the back face side.

  In the ventilation guide body 4 attached to the surface of the crown 31, a flow passage 401 that penetrates in the short direction of the ventilation guide body 4 and allows ventilation is formed in a region between adjacent spacers 42. Is done.

  In the present embodiment, the rectifying plate 41 is formed of a 0.2 mm thick polypropylene sheet so as to have flexibility, and the length in the longitudinal direction is 100 mm, and the length in the short direction is 15 mm. ing. However, the length of the rectifying plate 41 in the longitudinal direction is not limited to this. For example, the length of the rectifying plate 41 in the longitudinal direction may be in the range of 75 mm to 100 mm, and more preferably in the range of 85 mm to 100 mm, since the lift suppression effect is enhanced.

  Further, the length of the rectifying plate 41 in the short direction is not limited to this. For example, the length of the rectifying plate 41 in the short direction may be in the range of 5 mm to 30 mm, and more preferably in the range of 15 mm to 25 mm, since the lift suppression effect is enhanced.

  In the present embodiment, the rectifying plate 41 has flexibility, but is not limited thereto. For example, a material having rigidity may be used as long as the shape is curved in advance along the curved surface of the surface of the crown 31 to be attached. In the case of the rectifying plate 41 having flexibility, when the ventilation guide body 4 is attached to the surface of the crown 31, it bends along the shape of the crown 31, and the height of the region in the flow passage 401 formed is increased. It is preferable because the sheath width and the like are easily kept constant.

  The material constituting the rectifying plate 41 is not particularly limited as long as it has a strength that is not damaged by the wind pressure at the time of swinging, and other materials such as other synthetic resins and metal thin plates are used. Also good.

  In the present embodiment, four spacers 42 are arranged in the longitudinal direction of the ventilation guide body 4, and one spacer 42 is arranged in the vicinity of both ends in the longitudinal direction of the ventilation guide body 4. Is arranged. The spacer 42 has a longitudinal direction (that is, a direction parallel to the short direction of the rectifying plate 41) of 15 mm, and a short direction (that is, a direction parallel to the longitudinal direction of the rectifying plate 41) of 5 mm in plan view. It is a rectangle and its height (in other words, the thickness of the ventilation guide body 4) is 1 mm.

  However, the number of the spacers 42 is not limited to the above number, and two or three, depending on the flexibility of the rectifying plate 41 and the size of the opening portion of the flow passage 401 to be formed. Or five or more.

  The shape of the spacer 42 is not limited to the above-described shape, and may be various polygonal shapes such as a spindle shape, an oval shape, an oval shape, a circular shape, a rhombus shape, and a square shape in a plan view. The size of the spacer 42 (longitudinal direction and transversal direction) is not limited to the above numerical values, and can be appropriately set in view of the peel adhesive strength of the adhesive or the like that constitutes the adhesive surface 421.

  In the present embodiment, the opening height of the flow passage 401 is 1 mm, which is the same as the height of the spacer 42, but is not limited to this value. For example, the height of the spacer 42 may be within a range of 0.9 mm to 1.5 mm, and if the spacer 42 is within a range of 1 mm to 1.35 mm, the flow of air into the flow passage 401 is smooth. In addition, it is more preferable because an appropriate flow inhibiting effect is generated with respect to the air passing through the region in the flow passage 401.

  In the present embodiment, the adhesive surface 421 does not particularly limit the peel adhesion strength. Note that the current golf equipment rules at the time of application are disqualified if the member attached to the club is removed during the round, so the wind pressure due to the number of swings performed during the round (approximately 25 to 40 m / s) It is desirable to have such a peel adhesive strength that it can be peeled off with a force that does not peel off and does not damage the head. Here, the number of swings performed during the round is assumed to be about 14 to 100 (including swing).

  In the present embodiment, the ventilation guide body 4 is arranged so that its longitudinal direction is parallel or substantially parallel to the direction connecting the heel side and the toe side of the surface of the crown 31. "For example, the toe side of the ventilation guide body 4 from the face 33 side so that the opening portion of the flow passage 401 is directed in the swing direction and air can easily flow in according to the user's form and heel. It is also used in the sense that it includes those that are tilted so as to move away.

  Further, the ventilation guide body 4 is attached such that the longitudinal direction edge portion of the rectifying plate 41 on the face 33 side is 10 mm away from the upper edge of the face 33 toward the back face side, but is not limited to this value. . For example, the distance between the longitudinal edge portion of the rectifying plate 41 on the face 33 side and the upper edge of the face 33 is preferably in the range of 0 mm to 25 mm, and more preferably in the range of 5 mm to 20 mm. If it is less than 0 mm, the ventilation guide body 4 overhangs on the face 33 side, which violates the current golf equipment rules at the time of filing, and also becomes an obstacle when hitting the ball. This is because the lift suppression effect tends to decrease extremely.

  The operation of the wood club 1 will be described with reference to FIG. When the attachment 4 for a wood club is attached to the crown surface of a commercially available wood club head, it becomes equivalent to the wood club 1.

  A flow path through which air can flow from the face 33 side to the back face side of the head body 30 between the crown 31 surface and the lower surface portion of the rectifying plate 41 by the ventilation guide body 4 attached to the crown 31 surface. 401 is formed.

  The rectifying plate 41 closes the upper side of the flow passage 401, and can change the flow direction of the air flowing into the flow passage 401 and hitting the rectifying plate 41 into an irregular flow (see FIG. 5). Further, the spacer 42 can block the lateral side of the flow passage 401 in the short direction and can maintain the opening height of the flow passage 401.

  Further, since the ventilation guide body 4 is detachably attached to the head 3 as an attachment target, for example, when participating in a formal game, the ventilation guide body 4 can be easily removed and the ventilation guide body 4 is attached. The old wood club 1 can be returned to one that conforms to the current equipment rules.

  As described above, the wood club 1 (the wood club head 3) has the ventilation guide body 4, whereby the controllability of the club can be improved.

〔test〕
The result of the trial run by the inventor using the wood club 1 is shown as follows. As the base of the wood club 1, XP (1W: driver 272 g) of Company D was used. In the table, “◯” is a hit ball of a so-called nice shot, “T” is a top (low trajectory or goro), “H” is a hook (a trajectory that turns to the left), and “S” is a slice (a trajectory that turns to the right).

(Test 1)
In the test 1, the experiment was performed by changing the height of the spacer 42 (that is, the opening height of the flow passage 401), and the results are shown in Table 1. “No opening” is a test result in the case where a spacer 42 having a height of 1.01 mm and blocking the opening of the flow passage 401 is used.

(Test 2)
In Test 2, the experiment was performed by changing the length of the current plate 41 in the longitudinal direction, and the results are shown in Table 2.

(Test 3)
In Test 3, the experiment was performed by changing the length of the rectifying plate 41 in the short direction, and Table 3 shows the result.

(Test 4)
In Test 4, the experiment was performed by changing the length between the longitudinal edge portion of the rectifying plate 41 on the face 33 side and the upper edge of the face 33. Table 4 shows the results.

(Discussion)
As can be seen from Table 1, there was a clear difference in the success rate of trial hits between the case where the flow passage 401 is open and the case where the flow passage 401 is not open. That is, it can be seen that the nice shot rate is increased when the flow passage 401 is opened and air flows in and out. And even when the opening height of the flow passage 401 is low, the nice shot rate is reduced, and this is because the entrance of the flow passage 401 is too small and air does not easily flow in, so the lift suppression effect is also reduced. I guess that.

  Further, as can be seen from Table 2, the nice shot rate decreases as the length of the current plate 41 in the longitudinal direction becomes shorter. This is presumed that if the length of the rectifying plate 41 in the longitudinal direction is shortened, the amount of air that flows in decreases, and as a result, the lift suppression effect also decreases. It should be noted that 85mm is slightly bent than 75mm, but this seems to have been influenced by the habit or fatigue of the person who made the test, and is essentially estimated to be in a range with a high nice shot rate. .

  Further, as can be seen from Table 3, the nice shot rate is reduced whether the length of the rectifying plate 41 in the short direction is shorter or longer than 15 mm. This is because when the length of the rectifying plate 41 in the short direction is shortened, the effect of changing the flow direction of the air flowing into the flow passage 401 and hitting the rectifying plate 41 to an irregular flow is weak, and the lift suppression effect It is speculated that it has also declined. Further, if the length of the rectifying plate 41 in the short direction is increased, the effect of eliminating or suppressing the generation of lift generated in the wood club head 3 at the time of swinging is leveled, or the ventilation guide It is presumed that the body 4 causes air resistance and causes a decrease in swing speed.

  Normally, when the wood club 1 is swung, the flow velocity of the air flowing on the surface of the crown 31 becomes faster than the flow velocity of the air flowing on the surface of the sole 32, and lift is generated in the wood club head 3, and the swinging user himself / herself is imaged. Actually, the trajectory may be a trajectory passing above the club head trajectory. As a result, the hit ball is likely to be a so-called top shot or the like.

  However, by attaching the ventilation guide body 4 to the head 3 of the wood club 1, it becomes possible to swing in the orbit of the club head imaged by the user himself, resulting in a drastic reduction in miss shots. .

  Although this principle is not necessarily clear, when the air flowing on the surface of the crown 31 passes through the flow passage 401 due to the attachment to the ventilation guide body 4 to the wood club head 3, the flow of air is obstructed or the air The direction of the air flow is changed to an irregular flow, and the flow velocity of the air flowing on the surface of the crown 31 and the surface of the sole 32 is the same or almost the same, thereby eliminating or suppressing the generation of lift generated in the head 3 during the swing. It is presumed that they will do.

  In addition, although this inventor attached the member (namely, a simple protrusion) which is the same size as the ventilation | gas_flowing guide body 4 and does not have the flow path 401 on the crown 31 surface, a hit ball hits a so-called top etc. misshot. It was easy to be. Assuming from this result, in the case of a member without the passage 401, the air flowing on the surface of the crown 31 only exceeds the member and does not cause a decrease in the flow velocity, or the air flowing on the surface of the crown 31 is greatly disturbed. It seems that the track of the wood club head 3 at the time of swinging tends to become unstable. That is, the necessity of the flow path 401 is estimated.

  As described above, when the wood club attachment 4 is attached to the wood club 1 (wood club head 3) and the ventilation guide body 4 is provided, the wood club head 3 when the wood club 1 swings while having a simple structure. It is possible to suppress the generation of the lift force that occurs in the vehicle and to bring it closer to the swing trajectory imagined by itself. That is, the controllability of the wood club can be improved. Further, the ventilation guide body 4 can be sold as a single item as the attachment 4 for the wood club.

  In recent years, the golfing population has decreased and the player group is aging. On the other hand, female players are increasing. In general, elderly people and women tend not to travel with a driver shot, but the driver shot is a flower of golf. If it is a private round, the wood club having the ventilation guide body 4 in the present embodiment Since 1 can be expected to improve the flight distance, golf can be played happily.

The features described in the present specification and claims and their terms There is no intention of excluding some equivalent terms and expressions. It goes without saying that various modifications are possible within the scope of the technical idea of the present invention.
