[0004] [Patent Document 1] Jpn. Jpn. Published No. 58-047185 [Patent Document 2] Japanese Patent Application Publication No. 10-280773 Summary of the Invention [Problem to be solved by the invention]

[0005] The wire locks disclosed in Patent Documents 1 and 2 have a problem in that it is difficult to adjust the length of the portion of the wire body that contributes to mooring.

[0006] In addition, when the conventional means for enabling the above-mentioned adjustment is adopted in the wire locks disclosed in Patent Documents 1 and 2, it is often the case that some part of the means is particularly easy to destroy. If there is such a part that is particularly easy to destroy, there is a high possibility that the part will be destroyed and the moored item will be stolen.

[0007] The present invention has been made to solve such problems. An object of the present invention is to provide a mooring device that makes it easy to adjust the length of the part that contributes to mooring and reduces the risk of damage to the means that contributes to the adjustment. [Means for solving the problem]

[0008] The mooring device of the present invention will be described with reference to the drawings. The reference numerals in the drawings are used in this section to facilitate understanding of the contents of the invention. The reference numerals in the drawings are not intended to limit the contents of the invention to the scope shown in the drawings.

[0009] In order to solve the above-mentioned problems, according to one aspect of the present invention, the mooring device 10 includes a string 20 and a restraining lock 22. The restraining lock 22 restrains a certain portion of the string 20. At least three through holes 60, 60, 60, 62 are formed in the string 20. Any of the through holes 60, 60, 60, 62 formed in the string 20 is arranged so that it can be at least individually overlapped with at least two of the other through holes 60, 60, 60, 62 as the string 20 is bent. The restraining lock 22 includes a through shaft body 80, a one end surface forming body 82, and an other end surface forming body 84. The through shaft body 80 has a maximum value of the span smaller than the minimum value of the span of any of the at least three through holes 60, 60, 60, 62. The one end surface forming body 82 has a one end surface 100. The other end surface forming body 84 has a other end surface 140. The minimum value of the width of the one end face 100 is greater than the maximum value of the width of the through shaft body 80. The minimum value of the width of the other end face 140 is greater than the maximum value of the width of the through shaft body 80. One end of the through shaft body 80 is fixed to the one end face 100. The through shaft body 80 is aligned in the direction described below. The direction is the direction from the one end face 100 to the other end face 140 when described below. This is when the one end face 100 and the other end face 140 face each other so as to be aligned. An entrance hole 142 is formed in the other end face 140. The entrance hole 142 is for the other end of the through shaft body 80 to enter the other end face 140. The other end face forming body 84 has the other outer shell 120 and the axial movement limiting portion 122. The other outer shell 120 forms the other end face 140, the entrance hole 142, and the space 144. The axial motion limiting portion 122 is housed in a space 144 formed by the other outer shell 120. The axial motion limiting portion 122 limits the advancement and retreat of the penetrating shaft body 80 when the other end of the penetrating shaft body 80 enters the inside of the space 144 formed by the other outer shell 120 through the entrance hole 142. The maximum end face distance exceeds the sum of the thinnest and third thinnest thicknesses of the through hole formation portion. The maximum end face distance is the maximum distance between the one end face 100 and the other end face 140 when the axial motion limiting portion 122 limits the advancement and retreat of the penetrating shaft body 80. The thickness of the through hole formation portion is the thickness of the string 20 at the portion where the through holes 60, 60, 60, 62 are formed.The value obtained by subtracting the maximum occupied thickness from the maximum end face spacing is less than the larger of the following pair of linear distances. The linear distance is the linear distance from the edge of the point at which the minimum value of the diameter of one end face 100 or the other end face 140 is the smaller, to the outer periphery of the penetrating shaft body 80. The maximum occupied thickness is the sum of the thicknesses of the through hole formation points that is the largest among the combinations of thicknesses of the through hole formation points whose total is less than the maximum end face spacing.

[0010] At least three through holes 60, 60, 60, 62 are formed in the string 20. Any one of the through holes 60, 60, 60, 62 formed in the string 20 is arranged so as to overlap with at least two of the other through holes 60, 60, 60, 62 as the string 20 is bent. The maximum value of the diameter of the through shaft body 80 is smaller than the minimum value of the diameter of any of the at least three through holes 60, 60, 60, 62. This allows the through shaft body 80 to penetrate at least two of the at least three through holes 60, 60, 60, 62. Furthermore, the maximum end face distance exceeds the sum of the thinnest and third thinnest thicknesses of the through hole formation portion, so that the other end of the through shaft body 80 that has penetrated at least two of the at least three through holes 60, 60, 60, 62 can enter the inside of the space 144 formed by the other outer shell 120 through the entrance hole 142. When the other end of the penetrating shaft 80 enters the space 144 formed by the other outer shell 120, the axial movement limiting portion 122 restricts the movement of the penetrating shaft 80. This enables mooring. Moreover, the length of the portion contributing to mooring can be easily adjusted according to the combination of the through holes 60, 60, 60, 62 through which the penetrating shaft 80 passes.

[0011] In addition, in one aspect of the present invention described above, in order to shear the penetrating shaft 80 that is between the one end face 100 and the other end face 140 and that penetrates the through holes 60, 60, 60, 62 of the string 20 with a tool, the gap formed between the one end face 100 and the other end face 140 must be larger than the thickness of the blade of the tool. When the blade of the tool is single-edged and the angle formed by the tip is, for example, π / 4 radians, the height from the sharp point of the tip of the blade to the base of the blade is equal to the thickness of the base of the blade. When the blade of the tool is double-edged and the angle formed by the tip is, for example, π / 2 radians, the height from the sharp point of the tip of the blade to the base of the blade is equal to half the thickness of the base of the blade. As a result, if the gap formed between the one end face 100 and the other end face 140 is narrower than these thicknesses, it is possible to prevent the penetrating shaft 80 from being sheared by a tool with a large angle formed by the tip of the blade as described above.

[0012] When the penetrating shaft 80 penetrating any one of the through holes 60, 60, 60, 62 is restricted in its forward and backward movement by the axial movement restricting portion 122, the gap formed between the one end face 100 and the other end face 140 corresponds to the number of the penetrating through holes 60, 60, 60, 62. If the gap is narrower than the thickness of the blade described above when the number of the penetrating through holes 60, 60, 60, 62 is the largest and the gap is the smallest, then at least in that case, the penetrating shaft 80 can be prevented from being sheared. The number of the penetrating through holes 60, 60, 60, 62 is the largest and the gap is the smallest when the value obtained by subtracting the maximum occupied thickness from the maximum end face interval is less than the linear distance described below. The linear distance is the larger of the pair of linear distances from the edge of the point where the minimum value of the diameter is the smallest between the one end face 100 and the other end face 140 to the outer periphery of the penetrating shaft 80. This prevents the through shaft 80 from being sheared off by a tool having a large cutting edge such as those described above.

[0013] Even if the value obtained by subtracting the maximum occupied thickness from the maximum end face distance is less than the linear distance described above, it may be possible to shear the penetrating shaft 80 in the following case. This case is when the blade that enters the gap formed between the one end face forming body 82 and the other end face forming body 84 is a so-called thin blade, for example, a single-edged blade with an angle at its tip smaller than π / 4 radians. However, such a blade is more likely to deform than the blade with a large angle at its tip described above. If deformation occurs, it is difficult to shear the penetrating shaft 80. Therefore, in this respect, the tools that can clamp and shear the penetrating shaft 80 are limited.

[0014] As described above, the penetrating shaft 80 is prevented from being sheared by a tool with a large angle at the tip of the blade, and only a limited number of tools with a small angle at the tip of the blade can shear the penetrating shaft 80. As a result, the mooring device 10 according to an aspect of the present invention can reduce the risk of destruction of the means contributing to adjustment of the length of the portion contributing to mooring.

[0015] In addition, in the mooring device 10 according to one aspect of the present invention, it is desirable that one end 42 of the string 20 described above is looped. It is desirable that the other end of the string 20 can pass through that one end 42. In this way, when the other end of the string 20 passes through the looped one end 42, the string 20 can form a loop portion different from that one end 42. If such a loop portion can be formed, it becomes easier to adjust the length of the portion that contributes to mooring.

[0016] Alternatively, in the anchor 10 according to one aspect of the present invention, it is desirable that the through-hole 60, which can be individually overlapped with at least two of the other through-holes 60, 60, 60, 62 as the string 20 is bent, is arranged so that it can be simultaneously overlapped with two of the other through-holes 60, 60, 60 that can be individually overlapped. This makes it possible to reduce the gap that occurs between the one end face 100 and the other end face 140 in the case described below. This case is a case in which the other end of the string 20 penetrates one end 42 of the string 20 to form a loop, and the penetrating shaft 80 penetrates any pair of the at least three through-holes 60, 60, 60, 62 to form another loop. The reason why the above-mentioned gap can be reduced is that the penetrating shaft 80 can further penetrate the through-holes 60 that do not contribute to the formation of the latter loop. When the penetrating shaft 80 further passes through the through-hole 60 that does not contribute to the formation of the latter loop, the portion of the string 20 surrounding the through-hole 60 occupies the above-mentioned gap. Effect of the Invention

[0017] According to the present invention, it is possible to easily adjust the length of the portion contributing to mooring, and to reduce the risk of destruction of the means contributing to the adjustment. [Brief description of the drawings]

FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, the same components are denoted by the same reference numerals. The names and functions of the components are also the same. Therefore, detailed description thereof will not be repeated.

[0020] [Configuration Description] Fig. 1 is an external view of a mooring device 10 according to this embodiment. The configuration of the mooring device 10 according to this embodiment will be described with reference to Fig. 1.

[0021] The mooring device 10 in this embodiment includes a string 20 and a restraining lock 22. The string 20 connects a moored object (not shown) to a fixed object (not shown). In this embodiment, an example of the moored object is a bicycle. An example of the fixed object is a fence that is fixed to the ground and has steel pipes arranged horizontally and extending vertically. Of course, the moored object and the fixed object are not limited to these. The restraining lock 22 restrains the string 20 at a certain point.

[0022] Fig. 2 is an external view of the string 20 according to this embodiment. In Fig. 2, the middle part of the string 20 is omitted. In Fig. 2, the part of the body part 40 of the string 20 that contacts the annular end part 42 is shown in a twisted state. The configuration of the string 20 according to this embodiment will be described with reference to Fig. 2.

[0023] The string 20 according to this embodiment has a body 40 and an annular end 42. The body 40 according to this embodiment is a strip-shaped fabric with through holes formed therein, as described below. The fabric described above is made of high-strength threads. Thin steel wires are also woven into the fabric. This makes it difficult to cut the body 40 according to this embodiment with a common cutting tool such as a knife or scissors. The annular end 42 is formed by folding one end of the fabric constituting the body 40 and fixing the folded end to the fabric. As a result, the annular end 42 is formed at one end of the string 20 and is annular so that the end of the body 40 and the other end of the string 20 can pass through it.

[0024] The torso 40 according to this embodiment has three through-holes 60, 60, 60. The edges of the three through-holes 60, 60, 60 are fixed with well-known grommets. This prevents the edges of the three through-holes 60, 60, 60 from fraying. In this embodiment, the through-holes 60, 60, 60 are arranged so that they can be overlapped with the other through-holes 60, 60, 60 at the same time as the string 20 is bent. This allows the penetrating shaft 80, which will be described later, to pass through the three overlapped through-holes 60, 60, 60. Naturally, each of the through-holes 60, 60, 60 can be overlapped with only one of the other through-holes 60, 60, 60. In this embodiment, the inner circumference of the grommets fixed to the edges of the through-holes 60, 60, 60 is circular. This makes the span of the through-holes 60, 60, 60 uniform. The span of the through holes 60, 60, 60 is equal to the inner diameter of the through holes 60, 60, 60.

[0025] In this embodiment, a root through hole 62 is formed at the root of the annular end 42. A well-known eyelet is also fixed to the edge of the root through hole 62. The eyelet fixed to the edge of the root through hole 62 also serves as a metal fitting for fixing one end of the above-mentioned woven fabric to the woven fabric. The root through hole 62 can be individually overlapped with the three body through holes 60, 60, 60 as the string 20 is bent. In addition, in this embodiment, the inner circumference of the eyelet fixed to the edge of the root through hole 62 is circular. As a result, the span of the root through hole 62 is uniform. The span of the root through hole 62 is equal to the inner diameter of the root through hole 62.

[0026] In this embodiment, the body through holes 60, 60, 60 and the root through hole 62 are collectively referred to as "through holes."

[0027] 3 is an external view of the restraint lock 22 according to this embodiment. The configuration of the restraint lock 22 according to this embodiment will be described with reference to FIG.

[0028] In this embodiment, the restraining lock 22 has a through shaft body 80, a first end face forming body 82, and an second end face forming body 84.

[0029] The penetrating shaft body 80 has one end fixed to the one end surface forming body 82 and the other end entering the other end surface forming body 84. In this embodiment, the penetrating shaft body 80 is cylindrical except for the two grooves formed in the part entering the other end surface forming body 84 and the frustum-shaped part at the other end. A seal material 90 is fitted into one of the two grooves. A part of the axial movement limiting part 122 described later is fitted into the other of the two grooves. As a result, the span of the penetrating shaft body 80 is uniform in the part disposed between the one end surface forming body 82 and the other end surface forming body 84. In this part, the span of the penetrating shaft body 80 is equal to the diameter of the penetrating shaft body 80. In this embodiment, the diameter of the penetrating shaft body 80 is smaller than the inner diameter of any of the trunk through holes 60, 60, 60 and the root through hole 62. As a result, the maximum value of the diameter of the through shaft body 80 is smaller than the minimum value of the diameter of any of the trunk through holes 60, 60, 60 and the root through hole 62.

[0030] The one-end surface forming body 82 has one end surface 100. One end of the penetrating shaft body 80 is fixed to the one end surface 100. The one end surface 100 according to this embodiment is a circular, smooth flat surface. Therefore, in this embodiment, the span of the one end surface 100 is uniform. The span of the one end surface 100 is equal to the diameter of the one end surface 100. As is clear from FIG. 3, in this embodiment, the diameter of the one end surface 100 is larger than the diameter of the penetrating shaft body 80. As a result, in this embodiment, the minimum span of the one end surface 100 is larger than the maximum span of the penetrating shaft body 80.

[0031] The other end surface forming body 84 has the other end surface 140. Like the one end surface 100, the other end surface 140 according to this embodiment is also a circular, smooth plane. Therefore, in this embodiment, the other end surface 140 has a uniform width. The width of the other end surface 140 is equal to the diameter of the other end surface 140. As is clear from FIG. 3, in this embodiment, the diameter of the other end surface 140 is larger than the diameter of the penetrating shaft 80. As a result, in this embodiment, the minimum width of the other end surface 140 is larger than the maximum width of the penetrating shaft 80.

[0032] 3, in this embodiment, the one end face 100 and the other end face 140 face each other and are aligned along the direction of the penetrating shaft 80.

[0033] In the present embodiment, the other end surface forming body 84 has the other outer shell 120 , an axial movement limiting portion 122 , and a key cover 124 .

[0034] The other outer shell 120 forms the above-mentioned other end surface 140. The other outer shell 120 further forms an inlet hole 142 and a space 144. In the case of this embodiment, the inlet hole 142 is formed in the center of the other end surface 140. The space 144 formed by the other outer shell 120 communicates with the outside of the other outer shell 120 via the inlet hole 142.

[0035] The axial motion limiting portion 122 is housed in a space 144 formed by the other outer shell 120. When the other end of the through shaft 80 enters the inside of the space 144 formed by the other outer shell 120 through the entrance hole 142, the axial motion limiting portion 122 limits the advancement and retreat of the through shaft 80. The axial motion limiting portion 122 forms a keyhole (not shown) which will be described later. When a key (not shown) is inserted into the keyhole and the axial motion limiting portion 122 is operated, the axial motion limiting portion 122 releases the restriction on the advancement and retreat of the through shaft 80. Note that the specific structure for realizing such restriction and the release of the restriction is similar to that of a well-known lock called a "hitch lock". Therefore, a detailed description thereof will not be repeated here.

[0036] The key cover 124 detachably closes the end of the space 144 formed by the other outer shell 120. As described above, the axial movement limiting portion 122 is housed inside the space 144 formed by the other outer shell 120. As a result, when the key cover 124 is removed, a keyhole (not shown) of the axial movement limiting portion 122 is exposed.

[0037] 4 is a diagram showing a gap formed between one end surface 100 and the other end surface 140 according to this embodiment. The relationship between the maximum end surface distance and the maximum occupied thickness according to this embodiment will be described with reference to FIGS.

[0038] As described above, in this embodiment, the axial motion limiting portion 122 limits the advancement and retreat of the penetrating shaft 80 when the other end of the penetrating shaft 80 advances through the entrance hole 142 into the space 144 formed by the other outer shell 120. At this time, the penetrating shaft 80 can advance and retreat slightly due to dimensional errors of the penetrating shaft 80 and the axial motion limiting portion 122 and other factors. With such slight advancement and retreat, the distance between the one end face 100 and the other end face 140 can vary slightly. With such slight fluctuation, the distance between the one end face 100 and the other end face 140 has a maximum value and a minimum value. In this embodiment, the maximum value is the maximum end face distance. This is because the maximum end face distance is the maximum distance between the one end face 100 and the other end face 140 when the axial motion limiting portion 122 limits the advancement and retreat of the penetrating shaft 80. Here, it is assumed that FIG. 4 shows a state in which the distance between the one end face 100 and the other end face 140 is at its maximum.

[0039] As described above, the thickness of the through hole formation portion is the thickness of the string 20 at the portion where the body through holes 60, 60, 60 and the root through hole 62 are formed. In the case of this embodiment, since grommets are fixed at each of the body through holes 60, 60, 60 and the root through hole 62, the thickness of the through hole formation portion according to this embodiment is also the thickness of the grommets. At this time, there is some variation in the thickness of the through hole formation portion at the body through holes 60, 60, 60 due to dimensional errors of the grommets and other factors. Since the grommets fixed at the root through hole 62 are fixed to the two pieces of fabric described above, the thickness of the through hole formation portion at the root through hole 62 is different from the thickness of the through hole formation portion at the body through holes 60, 60, 60. As a result, the thickness of the through hole formation portion among the body through holes 60, 60, 60 and the root through hole 62 is ranked. In the case of this embodiment, the maximum end face distance exceeds the sum of the thinnest and third thinnest thicknesses of the through hole formation portions. As a result, the other end of the penetrating shaft body 80 can enter the inside of the space 144 formed by the other outer shell 120 after penetrating the body through holes 60, 60, 60 and the root through holes 62 that have the thinnest and third thinnest thicknesses at the through hole formation locations. Naturally, the other end of the penetrating shaft body 80 can enter the inside of the space 144 formed by the other outer shell 120 after penetrating the body through holes 60, 60, 60 and the root through holes 62 that have the thinnest and second thinnest thicknesses at the through hole formation locations. FIG. 4 shows a state in which the penetrating shaft body 80 passes through three body through holes 60, 60, 60.

[0040] In the present embodiment, since the through shaft 80 can penetrate at least two of the body through holes 60, 60, 60 and the root through hole 62, there are various combinations of the body through holes 60, 60, 60 and the root through hole 62 through which the through shaft 80 penetrates. The sum of the through hole formation portion thickness also varies according to the combination. As a result, the sum of the through hole formation portion thickness has a maximum value and a minimum value. The maximum value is the maximum occupied thickness according to this embodiment. The maximum occupied thickness according to this embodiment is the sum of the through hole formation portion thickness in the maximum combination of the through hole formation portion thicknesses that is less than the maximum end face spacing. In this embodiment, the sum of the through hole formation portion thicknesses of the three body through holes 60, 60, 60 is the maximum occupied thickness. As a result, the value of the gap width 160 shown in FIG. 4 is equal to the value obtained by subtracting the maximum occupied thickness from the maximum end face spacing.

[0041] As is clear from Fig. 4, in this embodiment, the diameter of the other end face 140 is smaller than the diameter of the one end face 100. As a result, the minimum value of the width across the other end face 140 is smaller than the minimum value of the width across the one end face 100. In this embodiment, the linear distances 162, 164 from the edge of the other end face 140 to the outer periphery of the penetrating shaft 80 are equal. As is clear from Fig. 4, the width 160 of the gap shown in Fig. 4 is significantly narrower than the linear distances 162, 164. As a result, the value obtained by subtracting the maximum occupied thickness from the maximum end face spacing is less than the larger of the linear distances 162, 164.

[0042] [Instructions for use] A first example of a method of using the mooring device 10 according to the present embodiment is as follows. First, the user passes the annular end 42 of the string 20 according to the present embodiment through a portion of the object from which the string 20 according to the present embodiment will not come off. Naturally, it is desirable that the portion from which the string 20 will not come off is a portion that will not break easily. In the case where the object is the above-mentioned fence, an example of such a portion from which the string 20 will not come off is when the string 20 is sandwiched between adjacent steel pipes that are arranged side by side and connected at the top and bottom. When the annular end 42 is passed through a portion from which the string 20 according to the present embodiment will not come off of the object to which the fixed object is attached, and the annular end 42 is passed through the end of the body 40, the annular end 42 will be connected to the portion from which the string 20 according to the present embodiment will not come off of the object to which the fixed object is attached. When the annular end 42 is connected to the portion from which the string 20 according to the present embodiment will not come off of the object to which the fixed object is attached, the user passes the end of the body 40 that has passed through the annular end 42 through a portion from which the string 20 will not come off of the object to be moored. Naturally, it is desirable that the part where the string 20 does not come off is also a part that does not break easily. When the object to be tethered is a bicycle, an example of such a part where the string 20 does not come off is the frame. When the end of the body 40 passes through the part of the object to be tethered where the string 20 does not come off, the user passes the through shaft 80 of the restraining lock 22 through the one of the body through holes 60, 60, 60 that is closest to the annular end 42. Next, the user bends the end of the body 40 and passes the through shaft 80 of the restraining lock 22 through the one of the body through holes 60, 60, 60 that is second closest to the annular end 42. Accordingly, the body 40 forms a loop 180 of the body 40 that is connected to the part of the object to be tethered where the string 20 does not come off. FIG. 4 shows the loop 180 of the body 40. Next, the user bends the end of the body 40 and passes the through shaft 80 of the restraining lock 22 through the one of the body through holes 60, 60, 60 that is farthest from the annular end 42. Next, the user passes the through shaft 80 into the entry hole 142 of the other end face 140 of the other end face forming body 84. When the through shaft 80 passes into the entry hole 142, the axial movement limiting portion 122 limits the advancement and retreat of the through shaft 80. As a result, the object to be tethered is tethered to the fixed object via the mooring device 10 according to this embodiment. FIG. 4 shows the body 40 of the string 20 in this state.

[0043] When releasing the tethered object, the user opens the key cover 124 and inserts a key (not shown) into the keyhole provided on the inside of the key cover. Once the key is inserted, the user operates the key to release the restriction imposed by the axial movement restricting unit 122. This allows the penetrating shaft body 80 to move freely back and forth, so the user can pull the penetrating shaft body 80 out of the entry hole 142 and the body through holes 60, 60, 60. Once the penetrating shaft body 80 has been pulled out, the user can pull the string 20 out of the attached object and the tethered object. This releases the tethered object.

[0044] A second example of the method of using the mooring device 10 according to the present embodiment is as follows. First, the user passes the annular end 42 of the string 20 according to the present embodiment through a portion of the object to be fixed from which the string 20 according to the present embodiment will not slip out and a portion of the object to be tethered from which the string 20 will not slip out. When the annular end 42 passes through those portions, the user passes the penetrating shaft body 80 through one of the body through holes 60, 60, 60 and the root through hole 62. Next, the user passes the penetrating shaft body 80 through the entry hole 142 of the other end face 140 of the other end face forming body 84. When the penetrating shaft body 80 enters the entry hole 142, the axial movement limiting portion 122 limits the advancement and retreat of the penetrating shaft body 80. As a result, the object to be tethered is moored to the object to be fixed via the mooring device 10 according to the present embodiment. FIG. 5 is a diagram showing a state in which the penetrating shaft 80 passes through the body through hole 60 and the root through hole 62 and enters the entrance hole 142.

[0045] [Explanation of Effects of the Present Embodiment] The mooring device 10 according to the present embodiment makes it easy to adjust the length of the portion contributing to mooring, and reduces the risk of damage to the means contributing to the adjustment.

[0046] [Description of Modifications] The above-described mooring device 10 is an example given to embody the technical idea of ​​the present invention. Various modifications can be made to the above-described mooring device 10 within the scope of the technical idea of ​​the present invention.

[0047] For example, the string 20 may not have an annular end 42. Naturally, the string 20 may not have a root through hole 62. In this case, the shape of the string 20 is a flat band from one end to the other. The positions of the body through holes 60, 60, 60 are not particularly limited. The number of through holes that the string 20 has is not particularly limited, as long as there are at least three.

[0048] Furthermore, the specific form of restraining lock 22 is not limited to that described above. Therefore, the shape of one end face 100 and the shape of the other end face 140 are not limited to circular. The location of one end face 100 where one end of penetrating shaft 80 is fixed and the location of the other end face 140 where entry hole 142 is formed are not limited to those described above.
