Description

Lacing and straps

[0001] The present invention relates to a string stopper and a strap that are attached to the end of a string.

[0002] Conventionally, straps having a string have utilized a string stopper attached to the end of the string. For example, Patent Document 1 discloses a string stopper including a holding member that holds the end of the string and a housing member that houses the holding member. The holding member has a pair of legs that hold the end of the string, and the opposing inner surfaces of the pair of legs are provided with multiple protrusions that penetrate the end of the string.

[0003] Japanese Patent Application Laid-Open No. 2020-54807

[0004] To improve the strength of a strap, a relatively hard string is sometimes used, such as a string made of a shape-memory material or a string with a core material. However, with conventional string stoppers such as those disclosed in Patent Document 1, it is difficult to make the protrusions bite into a hard string, and there is a problem in that the fixing strength of the string stopper to the string (i.e., the tensile strength of the strap) cannot be sufficiently ensured.

[0005] An object of the present invention is to provide a string stopper that can ensure the fixing strength of the string even when a hard string is used, and a strap that can ensure the tensile strength.

[0006] [1] A cord stopper according to one aspect of the present invention comprises a case member having a side wall portion extending along an axial direction and an opening that opens to one side in the axial direction, and a hanging member around which a cord end is hung and which is inserted into the case member through the opening, the hanging member comprising a head portion exposed to the outside of the case member through the opening, a body portion extending from the head portion along the axial direction within the case member, and a cord insertion hole penetrating the body portion in a first radial direction perpendicular to the axial direction, the body portion being arranged on the opposite side of the cord insertion hole from the head side and having a first cord support portion and a second cord support portion facing opposite sides to each other in the first radial direction, the first cord support portion and the second cord support portion each forming a cord space in which the cord end is arranged between the side wall portion and the hanging member.

[0007] [2] In the cord stopper of this aspect, it is preferable that the case member further comprises a bottom portion arranged opposite the opening and a cord outlet hole passing through the bottom portion in the axial direction, and that the hanging member has an opposing surface facing the bottom portion around the cord outlet hole, or a plurality of protrusions protruding toward the bottom portion and arranged with the cord outlet hole as their center.

[0008] [3] In the cord stopper according to this aspect, it is preferable that the cross-sectional shape of the cord outlet hole perpendicular to the axial direction has a shape in which the central portion in the first radial direction is narrowed.

[0009] [4] In the cord stopper according to this aspect, it is preferable that each of the first cord support portion and the second cord support portion has a support surface facing the side wall portion and a plurality of protrusions protruding from the support surface.

[0010] [5] In the cord stopper of this embodiment, the hanging member further comprises a pair of segments that together form the head and the body and have a slit formed between them, and a base that connects the pair of segments, and it is preferable that the slit divides the head and the body and communicates with the cord insertion hole.

[0011] [6] In the cord stopper according to this aspect, it is preferable that the hanging member further includes a through hole that penetrates the body in the first radial direction at a position adjacent to the base and that communicates with the slit in the axial direction.

[0012] [7] In the cord stopper according to this aspect, it is preferable that the pair of divided pieces have a pair of divided surfaces that contact each other at the head portion.

[0013] [8] In the cord stopper according to this aspect, it is preferable that the pair of split pieces have a pair of hole edge portions that face each other through the cord insertion hole in a second radial direction that is perpendicular to both the axial direction and the first radial direction.

[0014] [9] In the cord stopper according to this aspect, it is preferable that the axial dimension of each of the first cord support portion and the second cord support portion is equal to or greater than half the axial dimension of the body portion.

[0015]

[10] The strap according to this aspect includes any of the cord stoppers described above and a cord having the cord end portion to which the cord stopper is attached, and the cord may include a core portion and one or more covering layers covering the periphery of the core portion.

[0017] An embodiment of the present invention will now be described with reference to the drawings. As shown in Fig. 1, a cord stopper 1 of the first embodiment is attached to cord ends 2A, 2B, which are both ends of a cord 2, and includes a tubular case member 3 and a hanging member 4 that is inserted into the case member 3 and around which the cord ends 2A, 2B are hung. The cord stopper 1 of the first embodiment and the cord 2 to which the cord stopper 1 is attached constitute a strap 10. There are no particular limitations on how the strap 10 can be used, but for example, by attaching the cord stopper 1 to a belt member and attaching the cord 2 to any article, the article and the belt member can be connected.

[0018] There are no particular limitations on the structure or material of the string 2. For example, as illustrated in Fig. 2 , the string 2 of this embodiment includes a core 21 and multiple covering layers 22 laminated so as to cover the periphery of the core 21. Note that the covering layer 22 around the core 21 is not limited to multiple layers, and may be a single layer.

[0019] [Structure of Cord Holder] The structure of the cord holder 1 of this embodiment will be described with reference to Figures 3 to 9. Note that in Figures 4, 5, and 8, cord ends 2A and 2B are indicated by chain lines. Also, Figure 6 shows the state of the hanging member 4 when inserted into the case member 3, and Figure 7 shows the state of the hanging member 4 before insertion into the case member 3.

[0020] In the following description, the axial direction of the case member 3 is the Z direction, the insertion direction of the hanging member 4 into the case member 3 is the +Z direction, and the opposite direction is the -Z direction. Also, a first radial direction perpendicular to the axial direction of the case member 3 is the X direction, and the string ends 2A, 2B are arranged side by side in the X direction. Also, a second radial direction perpendicular to both the axial direction and the first radial direction of the case member 3 is the Y direction.

[0021] 3 to 5, the case member 3 is, for example, a resin molded product. As shown in FIGS. 3 to 5, the case member 3 includes a side wall 31 extending along the Z direction, an opening 32 opening on the −Z side of the side wall 31, a bottom 33 provided at the +Z end of the side wall 31, and a string outlet hole 34 penetrating the bottom 33 in the Z direction.

[0022] The side wall portion 31 extends to surround the space within the case member 3 and has a generally cylindrical shape. An inner surface 311 of the side wall portion 31 is disposed generally parallel to the Z direction. The outer surface 312 of the side wall portion 31 has an inclined surface 313 that is slightly inclined with respect to the Z direction so that the outer diameter of the cylindrical shape of the side wall portion 31 decreases toward the -Z side end of the side wall portion 31, and a convex portion 314 that protrudes radially outward from the inclined surface 313 near the -Z side end of the side wall portion 31. Note that a pair of recesses 315 are formed on the edge of the side wall portion 31 around the opening 32, and are disposed so as to sandwich the hanging member 4 therebetween.

[0023] The bottom 33 forms a bottom surface 331 that faces the internal space of the case member 3 in the Z direction. This bottom surface 331 is a flat surface that is approximately parallel to a plane perpendicular to the Z direction. The shape and number of the string outlet holes 34 are not particularly limited as long as the string ends 2A and 2B can be inserted therethrough. For example, as shown in FIG. 8 , the string outlet hole 34 in this embodiment is a single hole through which both string ends 2A and 2B are inserted, and the cross-sectional shape of the string outlet hole 34 perpendicular to the Z direction has a central portion in the X direction that narrows in the Y direction. In other words, the cross-sectional shape of the string outlet hole 34 has a shape in which two circles aligned in the X direction partially overlap. Note that the string outlet hole 34 may also be two holes aligned in the X direction so that the string ends 2A and 2B can be inserted therethrough.

[0024] The hanging member 4 is, for example, a resin molded product. As shown in Figures 6 and 7, the hanging member 4 deforms before and after insertion into the case member 3, but the following description will basically focus on the hanging member 4 inserted into the case member 3. As shown in Figure 6, the hanging member 4 includes a head 41, a body 42 extending from the head 41 in the +Z direction, and a string insertion hole 43 passing through the body 42 in the X direction.

[0025] The head 41 is disposed in the opening 32, which is one end of the case member 3. The head 41 has a flat cylindrical shape as a whole that fits into the opening 32 (see FIGS. 3 and 4).

[0026] The body 42 is disposed within the case member 3 (see FIGS. 4 and 5). The body 42 has a plate shape with a thickness in the Y direction as a whole. Specifically, the body 42 includes a body main body 421 and a pair of connecting portions 422, 423 that sandwich the string insertion hole 43 in the X direction and connect the head 41 and the body main body 421.

[0027] 5 and 6, the trunk main body 421 includes a first string support portion 47 and a second string support portion 48 that face opposite each other in the Y direction. The first string support portion 47 and the second string support portion 48 are each arranged to sandwich the string insertion hole 43 between them and the head 41 in the Z direction. Furthermore, the first string support portion 47 and the second string support portion 48 form, between themselves and the inner surface 311 of the side wall portion 31, string spaces S1, S2 in which the string end portions 2A, 2B are arranged.

[0028] The first string support portion 47 has a support surface 471 that extends toward the +Z side of the string insertion hole 43 and faces the -Y direction, and multiple protrusions 472 that protrude from the support surface 471 in the -Y direction. The multiple protrusions 472 are arranged side by side in the Z direction, and each protrusion 472 has a shape that extends along the X direction. Similarly, the second string support portion 48 has a support surface 481 that extends toward the +Z side of the string insertion hole 43 and faces the +Y direction, and multiple protrusions 482 that protrude from the support surface 481 in the +Y direction. The multiple protrusions 482 are arranged side by side in the Z direction, and each protrusion 482 has a shape that extends along the X direction. Note that the Z-direction dimension H1 of the first string support portion 47 and the second string support portion 48 is preferably at least half of the Z-direction dimension H2 of the body portion 42 (see FIG. 6 ).

[0029] The string insertion hole 43 penetrates the body 42 in the Y direction at a portion of the body 42 adjacent to the head 41. The cross-sectional shape of the string insertion hole 43 may be any shape that allows the string ends 2A, 2B aligned in the X direction to pass therethrough, and may be, for example, a rectangle (see FIG. 4).

[0030] As shown in Figure 6, the hanging member 4 of this embodiment comprises a pair of segments 401, 402 that together form the head 41 and body 42 described above and have a slit 44 formed between them, a base 45 that connects the pair of segments 401, 402, and a through hole 46 that penetrates the body 42 at a position adjacent to the base 45.

[0031] The slit 44 extends along the Z direction through the center of the hanging member 4 in the X direction and penetrates the hanging member 4 in the Y direction. This slit 44 includes a slit portion 441 that passes through the head portion 41 and a slit portion 442 that passes through the body portion 42. The head portion 41 is divided by the slit portion 441 into a pair of head pieces 41A and 41B, and the body portion 42 is divided by the slit portion 442 into a pair of body pieces 42A and 42B. In other words, the divided piece 401 includes a head piece 41A that is the -X side half of the head portion 41 and a body piece 42A that is the -X side half of the body portion 42, and the divided piece 402 includes a head piece 41B that is the +X side half of the head portion 41 and a body piece 42B that is the +X side half of the body portion 42. The first string support portion 47 and the second string support portion 48 are present in each of the body pieces 42A and 42B.

[0032] The head pieces 41A and 41B have parting surfaces 411 that contact each other in the X direction. The body pieces 42A and 42B have hole edge portions 431 that face each other in the X direction via the string insertion hole 43, and hole edge portions 432 that face the string insertion hole 43 in the −Z direction.

[0033] The width of the slit 44 in the X direction varies depending on the position in the Z direction. Specifically, the slit portion 441 does not form a gap between the head pieces 41A and 41B (i.e., the pair of dividing surfaces 411 and 412 are in contact with each other), and the slit portion 442 forms a gap between the body pieces 42A and 42B. The X direction dimension of the gap between the body pieces 42A and 42B is formed to increase toward the +Z direction from the center of the body piece 42 in the Z direction on the +Z side.

[0034] The base 45 is connected to the +Z side end of the body 42 (i.e., the +Z side end of the body pieces 42A and 42B) and connects the pair of split pieces 401 and 402. As shown in FIG. 5 , the base 45 has a plate shape that is disposed over a wider area in the Y direction than the body 42. That is, like the protrusions 472 and 482, the base 45 protrudes toward both the +Y side and the −Y side of the body 42. The base 45 also has an opposing surface 451 that faces the bottom surface 331 around the string outlet hole 34. This opposing surface 451 is not particularly limited, but preferably has a flat shape.

[0035] As shown in Fig. 6, the through-hole 46 penetrates the body 42 at a position adjacent to the base 45. As a result, parts of the body 42 on both sides of the through-hole 46 in the X direction function as hinge portions 424, 425. These hinge portions 424, 425 are elastically deformable in the X direction, as shown in Figs. 6 and 7. The hanging member 4 of this embodiment deforms from the state shown in Fig. 7 to the state shown in Fig. 6 due to the elastic deformation of the hinge portions 424, 425. When the hanging member 4 is in the state shown in Fig. 7, a gap is formed between the divided pieces 401, 402 large enough to allow the string ends 2A, 2B to pass through.

[0036] [Method of Attaching Cord Holder] A method of attaching the cord holder 1 of this embodiment to the cord 2 will now be described. First, the cord 2 is passed through the case member 3. Specifically, the loop portion of the doubled cord 2 may be passed through the opening 32 of the case member 3 and the cord outlet hole 34, or the cord ends 2A and 2B may be passed through the cord outlet hole 34 of the case member 3 and the opening 32.

[0037] Next, a hanging member 4 as shown in Figure 7 is prepared. Then, the string ends 2A and 2B are passed through the gap between the divided pieces 401 and 402, and hooked onto the hole edges 432 of the divided pieces 401 and 402. At this time, the string ends 2A and 2B are arranged side by side in the X direction. Furthermore, each of the string ends 2A and 2B is hung around the body portion 42 so as to sandwich the body portion 42 in the Y direction.

[0038] Finally, the hanging member 4 together with the string ends 2A and 2B is inserted into the case member 3 through the opening 32, and the head 41 is fitted into the opening 32. At this time, the base 45 of the hanging member 4 is guided by the pair of recesses 315 of the case member 3. As the hanging member 4 is inserted into the case member 3, the divided pieces 401 and 402 are pressed against each other in the X direction by the side wall portions 31, approaching each other, and the hinge portions 424 and 425 are elastically deformed. As a result, the divided surfaces 411 of the divided pieces 401 and 402 come into contact with each other, and the hole edge portions 431 of the divided pieces 401 and 402 clamp the string ends 2A and 2B in the X direction inside the string insertion hole 43 (see FIG. 4 ).

[0039] Furthermore, when the hanging member 4 is inserted into the case member 3, the first string support portion 47 forms a string space S1 between itself and the inner surface 311 of the side wall portion 31, and the second string support portion 48 forms a string space S2 between itself and the inner surface 311 of the side wall portion 31. The string ends 2A and 2B are disposed in these string spaces S1 and S2, respectively (see FIGS. 5 and 8 ). Specifically, the string end 2A contacts the first string support portion 47 and the second string support portion 48 of the body piece 42A, respectively, and is sandwiched between the first string support portion 47 and the side wall portion 31, and is also sandwiched between the second string support portion 48 and the side wall portion 31. Similarly, the string end 2B contacts the first string support portion 47 and the second string support portion 48 of the body piece 42B, respectively, and is sandwiched between the first string support portion 47 and the side wall portion 31, and is also sandwiched between the second string support portion 48 and the side wall portion 31.

[0040] In this way, the cord stopper 1 is attached to the cord ends 2A, 2B, and the strap 10 including the cord 2 and the cord stopper 1 is manufactured.

[0041] [Effects of this embodiment] (1) As described above, the cord stopper 1 of this embodiment comprises: a case member 3 having a side wall portion 31 extending along the axial direction (X direction) and an opening 32 that opens in the -Z direction; and a hanging member 4 on which cord ends 2A, 2B are hung and which is inserted into the case member 3 through the opening 32. The hanging member 4 comprises a head portion 41 that is exposed to the outside of the case member 3 through the opening 32; a body portion 42 that extends inside the case member 3 from the head portion 41 along the axial direction; and a cord insertion hole 43 that penetrates the body portion 42 in a first radial direction (Y direction) that is perpendicular to the axial direction. The body portion 42 is arranged on the opposite side of the cord insertion hole 43 from the head portion 41 and comprises a first cord support portion 47 and a second cord support portion 48 that face opposite each other in the first radial direction. The first cord support portion 47 and the second cord support portion 48 form cord spaces S1, S2 between themselves and the side wall portion 31, in which the cord ends 2A, 2B are arranged.

[0042] In this configuration, the string ends 2A, 2B drawn into the case member 3 are passed through the string insertion holes 43 and then wound around the body 42 of the hanging member 4. As a result, the string ends 2A, 2B are disposed in the string space S1 between the first string support portion 47 and the side wall portion 31 and the string space S2 between the second string support portion 48 and the side wall portion 31. That is, the string ends 2A, 2B are clamped by the string stopper 1 in each of the two string spaces S1, S2 in the string stopper 1, generating friction between the string stopper 1 and the string end 2A, 2B. Therefore, the string stopper 1 of this embodiment can be securely attached to the string ends 2A, 2B, and the strength of the string stopper 1 to fix the string ends 2A, 2B can be ensured even when a hard string 2 is used.

[0043] (2) In this embodiment, the case member 3 further includes a bottom portion 33 disposed opposite the opening 32 and a string outlet hole 34 axially penetrating the bottom portion 33. The hanging member 4 has an opposing surface 451 that faces the bottom surface 331 around the string outlet hole 34. With this configuration, when the string 2 pulled out of the case member 3 through the string outlet hole 34 is pulled, a force is applied to the hanging member 4 in the pulling direction, and the opposing surface 451 is pressed against the bottom portion 33. At this time, the opposing surface 451 of the hanging member 4 widely contacts the bottom portion 33 around the string outlet hole 34, preventing stress applied to the hanging member 4 from concentrating at one point. This prevents damage to the hanging member 4. Furthermore, clamping the string ends 2A and 2B between the opposing surface 451 of the hanging member 4 and the bottom portion 33 also improves the fixing strength of the string stopper 1 to the string 2.

[0044] (3) In this embodiment, the cross-sectional shape of the cord outlet hole 34 perpendicular to the Z direction has a shape that narrows at the center in the X direction. With this configuration, the two cord ends 2A, 2B can be inserted through the cord outlet hole 34 by passing the loop portion of the folded cord 2 through the opening 32 of the case member 3 and into the cord outlet hole 34. Furthermore, the positioning of the two cord ends 2A, 2B within the cord outlet hole 34 can be stabilized.

[0045] (4) In the present embodiment, each of the first cord support portion 47 and the second cord support portion 48 includes a support surface 471 facing the side wall portion 31 and a plurality of protrusions 472, 482 protruding from the support surface 471. This configuration increases the frictional force generated between the protrusions 472, 482 and the cord 2, thereby improving the fixing strength of the cord stopper 1 to the cord 2.

[0046] In this embodiment, the base 45 has a protruding shape similar to the protrusions 472 and 482, so the strength of the fastening of the cord stopper 1 to the cord 2 can be further improved.

[0047] (5) In this embodiment, the hanging member 4 further includes a pair of segments 401, 402 that together form the head 41 and the body 42 and have a slit 44 formed therebetween, and a base 45 that connects the pair of segments 401, 402. The slit 44 divides the head 41 and the body 42 and communicates with the cord insertion hole 43. With this configuration, before the hanging member 4 is inserted into the case member 3, the pair of segments 401, 402 can move toward or away from each other using the base 45 as a fulcrum. When the pair of segments 401, 402 are spaced apart, the cord ends 2A, 2B can be easily positioned in the cord insertion hole 43. This facilitates attachment of the cord stopper 1 to the cord 2.

[0048] (6) In this embodiment, the hanging member 4 further includes a through-hole 46 that penetrates the body 42 in the first radial direction (Y direction) at a position adjacent to the base 45 and communicates with the slit 44 in the axial direction. In this configuration, the portion of the body 42 near the through-hole 46 is more likely to elastically deform, and functions as the hinge portions 424, 425 when the pair of split pieces 401, 402 move toward or away from each other. This makes it easier to attach the cord stopper 1 to the cord 2.

[0049] (7) In this embodiment, the pair of split pieces 401, 402 have a pair of split surfaces 411, 412 that come into contact with each other at the head 41 when the hanging member 4 is inserted into the case member 3. This configuration can suppress rattling of the split pieces 401, 402 inside the case member 3 and improve the fixing strength of the cord stopper 1 to the cord 2.

[0050] In this embodiment, when the hanging member 4 is inserted into the case member 3, the slit 44 does not form a gap between the head pieces 41A and 41B, but forms a gap between the body pieces 42A and 42B. Such a shape of the slit 44 suppresses interference by the string 2 and the body pieces 42A and 42B when the divided pieces 401 and 402 approach each other, and ensures that the pair of divided surfaces 411 and 412 come into contact with each other.

[0051] (8) In this embodiment, the pair of split pieces 401, 402 have a pair of hole edges 431, 432 that face each other across the cord insertion hole 43 in a second radial direction (X direction) that is perpendicular to both the axial direction and the first radial direction. In this configuration, the pair of hole edges 431, 432 can clamp the cord ends 2A, 2B in the cord insertion hole 43 in the X direction. This improves the fixing strength of the cord stopper 1 to the cord 2.

[0052] (9) In the present embodiment, the axial dimension H1 of each of the first cord support portion 47 and the second cord support portion 48 (in the Z direction) is equal to or greater than half of the axial dimension H2 of the body portion 42. This configuration ensures an area in the cord stopper 1 that generates friction with the cord 2, thereby improving the fixing strength of the cord stopper 1 to the cord 2.

[0053] (10) The strap 10 of this embodiment includes the above-described cord stopper 1 and a cord 2 to which the cord stopper 1 is attached. Here, the cord 2 includes a core 21 and one or more covering layers 22 that cover the periphery of the core 21. With this configuration, the fixing strength of the cord stopper 1 to the cord 2 is improved, thereby improving the tensile strength of the strap 10. In other words, the strap 10 of this embodiment can reliably attach the cord stopper 1 to the cord 2 while improving the hanging strength of an article.

[0054] (11) Additionally, in this embodiment, the first cord support portion 47 and the second cord support portion 48 are each disposed along the inner surface 311 of the side wall portion 31. This ensures a wider range of area in which a certain level of frictional force is generated between the cord stopper 1 and the cord 2. Furthermore, in this embodiment, the outer surface 312 of the side wall portion 31 has a shape that allows an operator to easily grip the cord stopper with their fingers.

[0055] [Modifications] In the above embodiment, the specific shapes of the case member 3 and the hanging member 4 can be changed as desired. In the following description of modifications, the same reference numerals will be used for configurations corresponding to those in the above embodiment.

[0056] (First Modification) As shown in Fig. 9, in a hanging member 4A according to a modification, the first cord support part 47 may be configured to have one protrusion 472. Furthermore, although not shown, the second cord support part 48 may be configured to have one protrusion 482, similar to the first cord support part 47. Even in this modification, the cord stopper 1 can be attached to the cord ends 2A, 2B, as in the above embodiment. Note that the protrusions 472, 482 are preferably formed adjacent to the cord insertion hole 43.

[0057] 10 , in a hanging member 4B according to a second modification, the base 45 may include a plate portion 455 connecting the pair of segments 401, 402 and a plurality of protrusions 456 protruding in the +Z direction from the segments 401, 402. Similar to the base 45 of the above embodiment, the plate portion 455 protrudes from the body 42 in both the +Y direction and the −Y direction. The plurality of protrusions 456 protrude toward the bottom 33 and are disposed around the cord outlet hole 34. Unlike the above embodiment, in this modification, a gap in the Z direction is secured between the cord outlet hole 34 and the plate portion 455 of the base 45, allowing the cord ends 2A, 2B to pass through, and each of the plurality of protrusions 456 comes into contact with the bottom 33. These multiple protrusions 456 are arranged around the string withdrawal hole 34, so that the stress applied to the hanging member 4B when the string 2 is pulled is distributed in a balanced manner among the multiple protrusions 456, preventing the stress from concentrating in one place.

[0058] (Third Modification) As shown in Fig. 11 , a hanging member 4C according to a modification does not have to have the slits 44 of the above embodiment. That is, the head portion 41 and the body portion 42 of the hanging member 4C do not have to have a divided shape as in the above embodiment. In this modification, when attaching the cord stopper 1 to the cord 2, the cord ends 2A, 2B can be inserted into the cord insertion holes 43 in the Y direction. Also, as shown in Fig. 11 , in the hanging member 4C according to the modification, the base portion 45 can have a plurality of protrusions 456 arranged in the same manner as in the second modification.

[0059] (Other Modifications) The method of hanging the string ends 2A, 2B on the hanging member 4 is not limited to the method described in the above embodiment. For example, the string ends 2A, 2B may be passed through the +Z side of the base 45 so that the string ends 2A, 2B are wrapped around the body 42 one or more times, or the string ends 2A, 2B may cross each other inside the case member 3.

[0060] In the above embodiment, the cord stopper 1 is attached to the cord ends 2A and 2B, which are both ends of the cord 2, but the present invention is not limited to this. For example, the cord stopper 1 may be attached to one end of the cord 2.

[0061] In the above embodiment, the case member 3 has a cylindrical shape, but it may have other cylindrical shapes such as a square tube. In addition, the shape of the hanging member 4 may be modified to match the shape of the case member 3.

[0062] In the above embodiment, the arrangement of the string insertion hole 43 in the hanging member 4 is not limited to a position adjacent to the head portion 41, but may be any position in the body portion .

[0063] In the above embodiment, the first string support portion 47 and the second string support portion 48 may not have the protrusions 472, 482. In such a configuration, the string ends 2A, 2B may be sandwiched between the support surfaces 471, 481 of the first string support portion 47 and the second string support portion 48 and the side wall portion 31.

[0064] In the above embodiment, the plate-shaped base 45 forms a flat opposing surface 451, but the present invention is not limited to this. For example, the base 45 may have a shape other than a plate shape (for example, a shape with steps). Furthermore, the base 45 may have an opposing surface 451 with projections and recesses.

[0065] In the second and third modified examples, two protrusions 456 are illustrated on the hanging member 4, but the number and shape of the multiple protrusions 456 on the hanging member 4 are not limited to those in the modified examples. That is, the hanging member 4 may be provided with three or more protrusions 456 arranged around the string withdrawal hole 34. Furthermore, each protrusion 456 may have a surface that contacts the bottom 33.
