Description

[Technical Field]

[0001] The present disclosure relates to leads. [Background technology]

[0002] The mouthpieces of wind instruments such as saxophones and clarinets are generally fitted with reeds that generate vibrations for sound production. In recent years, in addition to traditional reeds made from natural materials such as reeds, resin reeds have become common. Because the specific gravity of resin reeds is greater than that of reeds, resins with as low a specific gravity as possible are preferred. Furthermore, resin reeds are often designed to be thinner than reed reeds to reduce their mass.

[0003] Patent Document 1 discloses thinning the heel portion of the lead, and Patent Document 2 discloses forming a groove in the heel portion of the lead that extends along the longitudinal direction of the heel. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] U.S. Patent No. 7,902,443 [Patent Document 2] U.S. Patent No. 8,766,072 Summary of the Invention [Problem to be solved by the invention]

[0005] With the reed described in Patent Document 1, when a typical mouthpiece and ligature are used, depending on the combination of mouthpiece and ligature, the thickness of the heel portion may be too thin, making it impossible to stably attach the reed to the mouthpiece.

[0006] In the reed described in Patent Document 2, the mass of the reed is lighter than in an embodiment in which the groove is omitted, but since this does not affect the flexure of the reed, it does not contribute to sound generation.

[0007] In consideration of the above circumstances, one aspect of the present disclosure aims to provide a reed that is excellent in blowing feel and sound production, and that can be attached stably. [Means for solving the problem]

[0008] In order to solve the above problems, a lead according to a preferred embodiment of the present disclosure has a first surface and a second surface opposite to the first surface, a base portion extending in a first direction, and a vamp extending from the base portion along the first direction, and one or both of the first surface and the second surface is provided with at least one groove extending along a second direction intersecting the first direction.

[0010] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. Note that the dimensions and scale of each part in the drawings are appropriately different from those in reality. Furthermore, the embodiments described below are preferred specific examples of the present disclosure. Therefore, various technically preferable limitations are applied to the present embodiments. However, the scope of the present disclosure is not limited to these embodiments unless otherwise specified in the following description to the effect that the present disclosure is limited.

[0011] 1. Embodiment 1-1. Reed usage status Fig. 1 is a cross-sectional view of a mouthpiece 100 to which a reed 10 according to an embodiment is attached. Fig. 1 shows a cross-section of the mouthpiece 100 in a state in which the reed 10 is attached to the mouthpiece 100 using a ligature 200.

[0012] Mouthpiece 100 is a structure that is attached to the body of a wind instrument such as a saxophone or clarinet, and is used by the player to blow air into the body. Mouthpiece 100 is generally cylindrical with a pair of openings. One of the pair of openings is attached to the body. The other of the pair of openings is an inlet through which the player blows air.

[0013] A table 101, which is a flat surface for attaching a reed 10, is provided on the outer peripheral surface of mouthpiece 100. Reed 10 is fixed to mouthpiece 100 by ligature 200 in a state in which it contacts table 101 and covers the other opening with a gap. Note that mouthpiece 100 and ligature 200 are not limited to the example shown in Fig. 1, and may be any combination known in the art.

[0014] The reed 10 is a long, thin plate-like member that vibrates when the player blows into it while attached to the mouthpiece 100. The reed 10 has a base material 11 and a vamp 12.

[0015] The substrate 11 is a part of the reed 10 and is a plate-like portion fixed to the table 101 of the mouthpiece 100 by the ligature 200, and is also called a heel. The substrate 11 has a first surface F1 and a second surface F2. The first surface F1 is the surface that contacts the table 101. The second surface F2 is the surface opposite to the first surface F1.

[0016] The vamp 12 is a part of the reed 10, extending from the base 11 toward the tip of the reed 10 and being a plate-like portion that becomes thinner toward the tip of the reed 10. The vamp 12 vibrates when the player blows air into it.

[0017] The lead 10 outlined above has a plurality of grooves 13. This makes it possible to provide a lead 10 that has excellent sound generation properties and can be stably attached. The lead 10 will be described below with reference to Figs. 2 to 5.

[0018] 1-2. Lead Fig. 2 is a perspective view of the lead 10 according to the embodiment. Fig. 3 is a plan view of the lead 10 according to the embodiment. Fig. 4 is a side view of the lead 10 according to the embodiment. Fig. 5 is a cross-sectional view taken along line AA in Fig. 3.

[0019] The lead 10 will be described below with reference to FIGS. 2 to 5. For convenience, the following description will use the mutually perpendicular X-axis, Y-axis, and Z-axis as appropriate. The X-axis is an axis along the width direction of the lead 10. The Y-axis is an axis along the longitudinal direction of the lead 10. The Z-axis is an axis along the thickness direction of the lead 10. Hereinafter, a direction along the X-axis is the X1 direction, and a direction opposite to the X1 direction is the X2 direction. The X1 direction or the X2 direction is an example of a "second direction." A direction along the Y-axis is the Y1 direction, and a direction opposite to the Y1 direction is the Y2 direction. The Y1 direction is an example of a "first direction." A direction along the Z-axis is the Z1 direction, and a direction opposite to the Z1 direction is the Z2 direction. However, the "second direction" is not limited to a direction parallel to the X-axis, as long as it has a directional component along the X-axis.

[0020] As shown in FIG. 2, the lead 10 extends in the direction along the Y-axis and has a first end E1, a second end E2, and a third end E3.

[0021] The first end E1 is the end of the substrate 11 in the Y2 direction. That is, the first end E1 is the end of the lead 10 in the Y2 direction. The second end E2 is the end of the substrate 11 in the Y1 direction. The third end E3 is the end of the vamp 12 in the Y1 direction, and is generally called a tip. That is, the third end E3 is the end of the lead 10 in the Y1 direction.

[0022] Thus, the lead 10 is divided into the substrate portion 11 and the vamp 12 with the second end E2 as the boundary. The substrate portion 11 has a shape extending in the Y1 direction from the first end E1 to the second end E2. The vamp 12 has a shape extending from the second end E2 of the substrate portion 11 along the Y1 direction.

[0023] Grooves 13-1 to 13-7 are provided on the second surface F2 of the base material 11. Furthermore, a groove 13-8 is provided on the second surface F2 of the vamp 12. Each of the grooves 13-1 to 13-8 is a depression extending in the direction along the X-axis. Each of the grooves 13-1 to 13-8 corresponds to the groove 13 shown in FIG. 1. Hereinafter, the grooves 13-1 to 13-8 may be referred to as groove 13 without distinction. The number of grooves 13 provided on the base material 11 is not limited to the example shown in the figure, and may be six or less or eight or more.

[0024] By providing grooves 13-1 to 13-7 on the second surface F2 of the substrate 11, the mass of the reed 10 can be reduced compared to a configuration without grooves 13. This allows the reed 10 to vibrate more easily, even when the substrate 11 is thick enough to accommodate a typical mouthpiece 100 and ligature 200. This improves the player's sense of the entire reed 10 vibrating, improving the playing feel. Furthermore, because at least one groove 13 extends along the X1 or X2 direction, which intersects with the Y1 direction, which is the longitudinal direction of the substrate 11, the reed 10 is more likely to flex. This means that not only the vamp 12 but also the substrate 11 is more likely to flex, making the entire reed 10 more likely to flex. This also reduces the distance between the reed 10 and the mouthpiece 100, facilitating sound production. From the above, a reed 10 with excellent sound production and stable attachment can be provided.

[0025] In this embodiment, grooves 13-1 to 13-8 are provided on the second surface F2, whereas no grooves are provided on the first surface F1. This allows grooves 13 to be provided on the substrate 11 while improving the adhesion between the mouthpiece 100 and the substrate 11 of the reed 10.

[0026] Furthermore, the grooves 13-1 to 13-7 are not provided on the vamp 12. This reduces the sense of discomfort felt by the player. The grooves 13 may be provided on the vamp 12 in a location that does not cause discomfort to the player, that is, in a location that is not in the part of the reed 10 that is held in the player's mouth when playing (usually a portion within about 25 mm from the tip of the vamp 12).

[0027] As shown in Figures 2 to 4, the grooves 13-1 to 13-8 are aligned in this order in the Y1 direction. In this way, the multiple grooves 13 provided in the base material 11 are aligned along the Y1 direction. This has the advantage of making it easier to impart suitable flexibility to the lead 10. In the example shown in Figures 2 to 4, the grooves 13-1 to 13-8 are aligned at equal intervals P. Note that the intervals P between the multiple grooves 13 do not have to be equal. For example, the intervals P between the multiple grooves 13 may decrease or increase as they move in the Y1 direction, but it is preferable that they decrease.

[0028] 2 to 4, grooves 13-1 to 13-8 have the same widths W-1 to W-8 along the Y axis. However, while grooves 13-1 to 13-7 have constant widths W-1 to W-7, width W-8 of groove 13-8 decreases from both ends of base material 11 toward the center in the width direction. Here, groove 13-8 is composed of a pair of grooves separated at the center in the width direction of base material 11 or vamp 12.

[0029] Thus, grooves 13-1 to 13-8 include groove 13-8 whose width in the direction along the Y axis is not constant. This has the advantage of easily imparting suitable flexibility to lead 10. Groove 13-8 may be a single groove that is not divided at the center in the width direction of base portion 11 (direction along the X axis), connecting the pair of grooves, or may be a groove of constant width (width in the direction along the Y axis). Furthermore, widths W-1 to W-7 of grooves 13-1 to 13-7 do not have to be constant. For example, they may decrease or increase from both ends toward the center in the width direction of base portion 11, although it is preferable that they increase.

[0030] The cross-sectional shape of the groove 13 is such that the width decreases toward the bottom of the groove 13. This allows the substrate 11 to be easily bent by the groove 13 while ensuring the mechanical strength required for the substrate 11. In the example shown in Fig. 4, the cross-sectional shape of the groove 13 is U-shaped. Note that the cross-sectional shape of the groove 13 is not limited to the example shown in Fig. 4, and may be, for example, V-shaped.

[0031] The reed 10 is made of a resin composition. That is, the base material 11 and the vamp 12 are each made of a resin composition. As a result, the effect of providing the grooves 13 in the base material 11 is significant, since the specific gravity of resin is generally greater than that of reeds.

[0032] The resin composition constituting the lead 10 includes a resin. While the resin contained in the resin composition is not particularly limited, it is preferable to use a resin with a high specific gravity and high elasticity in order to minimize the effects of temperature and creep resistance. Specifically, it is preferable to use an engineering plastic such as a liquid crystal polymer. When an engineering plastic is used as the resin in the resin composition, changes in properties due to temperature changes can be minimized. Furthermore, since engineering plastics not only have a high specific gravity among resins but are also hard, the use of such a resin provides significant benefits. The resin composition constituting the lead 10 may also contain organic or inorganic fillers or fibrous materials in addition to the resin. Furthermore, the surface of the lead 10 may be coated or painted with an organic or inorganic material. Furthermore, the material constituting the lead 10 is not limited to a resin composition and may be, for example, a natural material such as reed or an inorganic material such as metal.

[0033] When the reed 10 is made of a resin composition, the provision of the grooves 13-1 to 13-8 can reduce the mass of the reed 10 by about 6% compared to an embodiment without the grooves 13. As a result, the reed 10 can vibrate more easily, improving the playing feel.

[0034] The lead 10 made of a resin composition is molded, for example, by injection molding, etc. Here, the groove 13 may be formed by a mold used during molding, or may be formed by mechanical processing such as NC processing or laser processing after molding.

[0035] As shown in FIG. 4, the distances Da-1 to Da-7 between the bottoms of the grooves 13-1 to 13-7 at the center in the width direction of the base member 11 and the first surface F1 are in the order of increasing length. The distances Da-1 to Da-7 correspond to the grooves 13-1 to 13-7, respectively. For example, the distance Da-1 is the distance between the bottom of the groove 13-1 at the center in the width direction of the base member 11 and the first surface F1. In this embodiment, the depth of the groove 13-8 at the center in the width direction of the base member 11 is zero. Hereinafter, the distances Da-1 to Da-7 may be referred to as the distance Da without distinction. The distances Da between two adjacent grooves 13-1 to 13-7 may be equal to each other.

[0036] Similarly, the order of distances Db-1 to Db-8 between the bottoms of grooves 13-1 to 13-8 at the ends in the width direction of the base member 11 and the first surface F1 is from largest to smallest. Note that distances Db-1 to Db-8 correspond to the grooves 13-1 to 13-8, respectively. For example, distance Db-1 is the distance between the bottom of groove 13-1 at the end in the width direction of the base member 11 and the first surface F1. Hereinafter, distances Db-1 to Db-8 may be referred to as distance Db without distinction. Note that the distances Db between two adjacent grooves 13 of grooves 13-1 to 13-8 may be equal to each other.

[0037] In this way, the distance Da or the distance Db between the bottom of the plurality of grooves 13 and the first surface F1 becomes shorter for grooves 13 closer to the vamp 12. This has the advantage of making it easier to impart suitable flexibility to the lead 10.

[0038] As shown in FIG. 5, the distance Db between the bottom of the groove 13 and the first surface F1 at the widthwise end of the substrate 11 is smaller than the distance Da between the bottom of the groove 13 and the first surface F1 at the widthwise center of the substrate 11. Here, the distance between the bottom of the groove 13 and the first surface F1 gradually decreases from the widthwise center to the widthwise end of the substrate 11. This has the advantage of making it easier to impart suitable flexibility to the reed 10. Here, the suitable flexibility of the reed 10 is a flexibility that brings the tip of the reed 10 closer to the mouthpiece 100 when the reed 10 is held in the mouth. When such flexibility of the reed 10 occurs more easily, it becomes easier to produce sound.

[0039] Although there are no particular limitations on the thickness Dc of the base material portion 11, it is preferable that it be 2.4 mm or more. In this case, many combinations of existing products can be used as the mouthpiece 100 and the ligature 200.

[0040] 2. Variations The present disclosure is not limited to the above-described embodiments, and various modifications are possible as described below. Furthermore, the embodiments and modifications may be combined as appropriate.

[0041] 2-1. Variation 1 6 is a plan view of a lead 10A according to Modification 1. The lead 10A is configured similarly to the lead 10 of the aforementioned embodiment, except that it has a substrate 11A instead of the substrate 11 of the aforementioned embodiment. The substrate 11A is configured similarly to the substrate 11 of the aforementioned embodiment, except that it has grooves 14-1 to 14-8 instead of the grooves 13-1 to 13-8 of the aforementioned embodiment. Hereinafter, the grooves 14-1 to 14-8 may be referred to as grooves 14 without distinction. The number of grooves 14 provided in the substrate 11A is not limited to the example shown in the figure, and may be seven or less or nine or more.

[0042] The grooves 14-1 to 14-8 are configured similarly to the grooves 13-1 to 13-8 of the above-described embodiment, except that they have different widths. In the example shown in Fig. 6, the widths W-1 to W-8 of the grooves 14-1 to 14-8 are arranged in the order W-1 to W-8 from largest to smallest. Note that the widths of any two adjacent grooves 14 of the grooves 14-1 to 14-8 may be equal.

[0043] The lead 10A can be provided with excellent sound generation and stable attachment properties according to the first modification. Another advantage is that the groove 14 can easily enhance the effect of reducing the mass of the lead 10A.

[0044] 2-2. Variation 2 FIG. 7 is a plan view of a lead 10B according to Modification 2. The lead 10B has the same configuration as the lead 10 of the aforementioned embodiment, except that it has a substrate 11B instead of the substrate 11 of the aforementioned embodiment. The substrate 11B has the same configuration as the substrate 11 of the aforementioned embodiment, except that it has grooves 15-1 to 15-6 instead of the grooves 13-1 to 13-8 of the aforementioned embodiment. Hereinafter, the grooves 15-1 to 15-6 may be referred to as grooves 15 without distinction. The number of grooves 15 provided in the substrate 11B is not limited to the example shown in the figure, and may be five or less or seven or more. However, from the viewpoint of enhancing the symmetry of the shape of the lead 10B, it is preferable that the number of grooves 15 provided in the substrate 11B is an even number.

[0045] Each of the grooves 15-1 to 15-6 has the same configuration as the groove 13 of the above-described embodiment, except that the grooves 15-1 to 15-6 extend in different directions. Here, the grooves 15-1 to 15-3 are aligned in this order in the Y1 direction and extend in a direction inclined relative to the X axis. In contrast, the grooves 15-4 to 15-6 are aligned in this order in the Y1 direction and extend in a direction inclined opposite to the X axis from the grooves 15-1 to 15-3.

[0046] Here, groove 15-1 and groove 15-4 intersect with each other at the center in the width direction of base member 11B. Similarly, groove 15-2 and groove 15-5 intersect with each other at the center in the width direction of base member 11B. Groove 15-3 and groove 15-6 intersect with each other at the center in the width direction of base member 11B.

[0047] Groove 15-2 connects to groove 15-6 at the end of substrate 11B in the X1 direction and connects to groove 15-4 at the end of substrate 11B in the X2 direction. Similarly, groove 15-5 connects to groove 15-1 at the end of substrate 11B in the X1 direction and connects to groove 15-3 at the end of substrate 11B in the X2 direction.

[0048] The above-described second modification also provides a reed 10B that has excellent sound generation and can be stably attached. Furthermore, since localized force is less likely to be applied to a portion of the reed 10B in the longitudinal direction, the reed 10B is less likely to break. Another advantage is that the ligature is less likely to slip off the reed 10B.

[0049] 2-3. Variation 3 8 is a plan view of a lead 10C according to Modification 3. The lead 10C has the same configuration as the lead 10 of the aforementioned embodiment, except that it has a substrate 11C instead of the substrate 11 of the aforementioned embodiment. The substrate 11C has the same configuration as the substrate 11 of the aforementioned embodiment, except that it has grooves 16-1 to 16-5 instead of the grooves 13-1 to 13-8 of the aforementioned embodiment. Hereinafter, the grooves 16-1 to 16-5 may be referred to as grooves 16 without distinction. The number of grooves 16 provided in the substrate 11C is not limited to the example shown in the figure, and may be four or less or six or more.

[0050] The grooves 16-1 to 16-5 are configured similarly to the groove 13 of the above-described embodiment, except that they extend in different directions. Here, the grooves 16-1 to 16-5 are lined up in this order in the Y1 direction and extend in a direction inclined with respect to the X axis. Here, the extension directions of the grooves 16-1 to 16-5 are parallel to each other. However, the extension directions of the grooves 16-1 to 16-5 do not have to be parallel to each other.

[0051] The lead 10C has excellent acoustic properties and can be stably attached, and can be provided by the above-described modification 3. Furthermore, since the groove 16 extends in a direction inclined with respect to the X-axis, the groove 16 can be easily processed without strictly considering the orientation of the lead 10C.

[0052] 2-4. Variation 4 9 is a plan view of a lead 10D according to Modification 4. The lead 10D is configured similarly to the lead 10 of the aforementioned embodiment, except that it has a substrate 11D instead of the substrate 11 of the aforementioned embodiment. The substrate 11D is configured similarly to the substrate 11 of the aforementioned embodiment, except that it has grooves 17-1 to 17-4 instead of the grooves 13-1 to 13-8 of the aforementioned embodiment. Hereinafter, the grooves 17-1 to 17-4 may be referred to as grooves 17 without distinction. The number of grooves 17 provided in the substrate 11D is not limited to the example shown in the figure, and may be three or less or five or more.

[0053] Each of the grooves 17-1 to 17-4 is configured similarly to the groove 13 of the above-described embodiment, except that the grooves 17-1 to 17-4 have different shapes when viewed along the Z axis. Here, the grooves 17-1 to 17-4 are arranged in this order in the Y1 direction. When viewed along the Z axis, the groove 17 is W-shaped and is made up of multiple portions inclined with respect to the X axis. In the illustrated example, the shapes of the grooves 17-1 to 17-4 when viewed along the Z axis are the same. However, the shapes of the grooves 17-1 to 17-4 when viewed along the Z axis may be different from each other.

[0054] The fourth modification also provides a reed 10D that has excellent sound production and can be stably attached. In addition, the groove 17 has a shape that includes a curved portion when viewed in the direction along the Z axis, which is advantageous in that the ligature is less likely to slip off the reed 10D.

[0055] 2-5. Variation 5 10 is a plan view of a lead 10E according to Modification 5. The lead 10E has the same configuration as the lead 10 of the aforementioned embodiment, except that it has a substrate 11E instead of the substrate 11 of the aforementioned embodiment. The substrate 11E has the same configuration as the substrate 11 of the aforementioned embodiment, except that it has grooves 18-1 to 18-6 instead of the grooves 13-1 to 13-8 of the aforementioned embodiment. Hereinafter, the grooves 18-1 to 18-6 may be referred to as grooves 18 without distinction. The number of grooves 18 provided in the substrate 11E is not limited to the example shown in the figure, and may be five or less or seven or more.

[0056] Each of the grooves 18-1 to 18-6 has the same configuration as the groove 13 of the above-described embodiment, except that the grooves 18-1 to 18-6 have different shapes when viewed along the Z axis. Here, the grooves 18-1 to 18-6 are arranged in this order in the Y1 direction. When viewed along the Z axis, the groove 18 has a curved shape that is convex in the Y1 direction. In the illustrated example, the shapes of the grooves 18-1 to 18-6 when viewed along the Z axis are the same. However, the shapes of the grooves 18-1 to 18-6 when viewed along the Z axis may be different from each other.

[0057] The fifth modification also provides a reed 10E that has excellent sound production and can be stably attached. In addition, because the groove 18 has a curved shape when viewed in the direction along the Z axis, there is also the advantage that the ligature is less likely to slip off the reed 10E.

[0058] 2-6. Variation 6 In the above-described embodiment, an example is given in which a plurality of grooves 13 are provided on the second surface F2, but this is not limiting, and at least one groove extending in a direction having a directional component along the X-axis may be provided on the first surface F1. In this case, the groove 13 provided on the second surface F2 may be omitted. Furthermore, in this case, the shape, number, and other aspects of the grooves provided on the first surface F1 may be the same as or different from the aspects of the grooves 13 provided on the second surface F2 when viewed in the thickness direction of the base portion 11.

[0059] 2-7. Variation 7 In the above-described embodiment, the grooves 13 extend across the entire width of the base material 11, but the present invention is not limited to this. For example, grooves may be provided partially in the center or both ends in the width direction of the base material 11. In this case, the lengths of the multiple grooves provided in the base material 11 may be different from one another.

[0060] 3. Notes From the above-described exemplary embodiments and modifications, the following aspects can be understood, for example.

[0061] (Appendix 1) A first embodiment, which is a preferred example of a lead of the present disclosure, has a first surface and a second surface opposite to the first surface, a base portion extending in a first direction, and a vamp extending from the base portion along the first direction, and one or both of the first surface and the second surface is provided with at least one groove extending along a second direction intersecting the first direction.

[0062] According to the above-described embodiment, at least one groove is provided on one or both of the first and second surfaces of the base member, thereby reducing the mass of the reed compared to embodiments without grooves. This allows the reed to vibrate more easily, even if the base member is thick enough to accommodate a typical mouthpiece and ligature, improving the playing feel. Furthermore, since the at least one groove extends along a second direction that intersects with the first direction, which is the longitudinal direction of the base member, this facilitates bending of the reed. This also facilitates sound production. From the above, a reed that offers excellent playing feel and sound production and can be attached stably can be provided.

[0063] (Note 2) In a second aspect, which is a preferred example of the first aspect, the first surface is a surface that comes into contact with a mouthpiece, and the at least one groove is provided on the second surface. According to the above aspect, grooves can be provided in the base material while improving adhesion between the mouthpiece and the base material of the reed.

[0064] (Note 3) In the third aspect, which is a preferred example of the second aspect, the distance between the bottom of the at least one groove and the first surface decreases from the center to the end of the base portion in the second direction. This aspect has the advantage of easily imparting suitable flexibility to the lead.

[0065] (Note 4) In a fourth aspect, which is a preferred example of the second or third aspect, the at least one groove is a plurality of grooves arranged along the first direction. This aspect has the advantage of easily imparting suitable flexibility to the lead.

[0066] (Note 5) In the fifth aspect, which is a preferred example of the fourth aspect, the distance between the bottom of the plurality of grooves and the first surface becomes shorter for grooves closer to the vamp. This aspect has the advantage of easily imparting suitable flexibility to the reed.

[0067] (Supplementary Note 6) In a sixth aspect, which is a preferred example of any of the first to fifth aspects, the width of the at least one groove may be a groove having a variable width. This aspect has the advantage of easily imparting suitable flexibility to the lead.

[0068] (Appendix 7) In the seventh embodiment, which is a preferred example of any of the first to sixth embodiments, the base material and the vamp are each made of a resin composition. In the above embodiments, the specific gravity of resin is generally greater than that of reeds, so the effect of providing grooves in the base material is significant.

[0069] (Appendix 8) In an eighth aspect, which is a preferred example of the seventh aspect, the resin composition includes an engineering plastic. In this aspect, it is possible to reduce changes in properties due to temperature changes. Furthermore, since engineering plastics not only have a high specific gravity among resins but are also hard, the effect is remarkable when such resins are used.

[0070] (Supplementary Note 9) In a ninth aspect, which is a preferred example of any of the first to eighth aspects, the at least one groove is not provided in the vamp. In the above aspect, it is possible to reduce the discomfort felt by the player. [Explanation of symbols]
