Description

The present invention relates to a document binding tool for binding documents for the purpose of storage or the like.

As an example of a document binding tool, there is a binding tool described in Patent Document 1 below. This binding tool is a file body consisting of a front cover and a back cover, to which a linear material with elastic restoring force called a binding foot is attached. Tighten with a binding plate member. The binding plate member has a slider that moves along the binding plate member, and the portion of the above-mentioned binding foot that protrudes from the binding plate member is held by bending with the slider.

The paper binding tool described in Patent Document 2 binds paper documents using only a wire rod such as a so-called binding band. That is, the main member is a flexible resin string (wire) that passes through the double punched hole provided in the document and has a receiving substrate at the base end, and the tip of the string passed through the document. A tightening piece (retaining member) having an insertion hole for the string body is detachably attached to the string body for binding the document. The string body has a large number of receiving claws having a triangular cross section with the base end side as the apex on its peripheral surface, and the tightening piece is located at the inner end of the insertion hole in the direction opposite to the receiving claw of the string body. It has a locking piece with a tapered surface. Therefore, when the string is passed through the insertion hole of the tightening piece separated from the string, the tightening piece slides only in one direction toward the base end side of the string, is locked to the receiving claw, and comes out. There is no. Therefore, when the tip of the string is passed through the double punch hole of the document and the tightening piece is inserted through the tip of the string protruding from the document, the receiving claw and the locking piece are engaged so as not to come off. , The document is bound between the receiving board and the tightening piece. Cut off the tip of the string protruding from the insertion hole.

Similar to Patent Document 2, Patent Document 3 also describes a document binding tool composed of a wire rod and a retaining member that slides only in one direction thereof. A large number of cone-shaped ribs (diameter-enlarged portions) are formed in the wire rod of the same document 3, and a tongue piece portion toward the center is formed in the opening of the retaining member. Since the wire can slide only in the direction in which it is inserted into the opening of the retaining member from the tip end portion, the documents can be bound using only those wires and the retaining member.

The binding tool of Patent Document 1 has an advantage that the bound documents can be replaced, but there is a problem in that the documents are bound compactly and stored in a stable state for a long period of time. That is, since the tip of the binding foot protruding from the binding plate member is bent and held by the slider along the binding plate member, documents are inserted by the thickness of the binding foot and the slider in addition to the thickness of the binding plate member. Requires extra space on the document shelf. In addition, when browsing the documents stored together, the binding legs may come off from the slider, so it is difficult to stably store the bound documents. In particular, when the document is thick, the length of the binding leg that can be bent by the slider does not remain sufficiently, so that the binding leg tends to come off from the slider.

Although the paper binding tool of Patent Document 2 can bind documents compactly, it is not sufficient in the sense that the documents can be smoothly taken in and out of the document shelf and viewed without damaging the documents. That is, the paper binding tool can prevent the string from protruding from the tightening piece by cutting off the tip of the string protruding from the insertion hole after binding the document, but the receiving substrate and the tightening piece itself are the document. Since each of them protrudes from the paper surface, it is easy to get caught when putting it in the document shelf. In addition, since the bound document can be pressed only at two points around the binding hole, the binding force is concentrated in that area and the document is damaged, or the document is bent near the unpressed corner and the thickness becomes thicker. It may increase or tear. The document binding device of Patent Document 3 has the same problem.

In consideration of the above points, the present invention can bind documents compactly, and it is easy to put them in and out of the document shelf, and it is stable without the documents coming off or being damaged even if the documents are repeatedly browsed. The purpose is to provide a preferred document binding tool that is stored in a stable manner.

The document binding tool of the present invention binds a document having two binding holes through a wire rod (including a string-shaped or rod-shaped one) in each binding hole.
-It has a pair of sheets that can be stacked on both outer surfaces of the above documents (the two surfaces that are exposed to the outermost side of a plurality of overlapping documents), and the wire rod is placed in two places on the first sheet, which is one of them. Is provided upright, and the other second sheet is provided with two through holes for passing each of the above wires (inserting each wire from the tip side).
-A plurality of protrusions (including uneven ones) are formed on the outer peripheral surface of the wire rod at intervals in the length direction of the wire rod, and a retaining piece is formed on the inner peripheral surface of the through hole. At least one of the protrusion and the retaining piece is a material (synthetic resin or the like) that can be elastically deformed, and the direction in which the wire is inserted into the through hole (from the tip end to the base end portion). Having a shape that allows only relative movement (slide) of
-And, each of the above-mentioned sheets is characterized by having a length extending substantially over the entire length of the edge of the above-mentioned document on the side having the binding hole.
The "shape that allows only relative movement in the direction in which the wire rod is inserted into the through hole" for the protrusion and the retaining piece is, for example, the receiving claw described in Patent Document 2. Examples thereof include a locking piece, or a shape like the rib and tongue piece described in Patent Document 3. That is, the protrusions formed on the outer peripheral surface of the wire have a tapered or serrated cross section in which the diameter or thickness gradually increases and decreases sharply from the tip to the proximal end. It is preferable that the retaining piece of the through hole comes into contact with the surface of the protrusion.
Further, the width of each sheet having the above length may be narrow enough to cover the band-shaped range along the two binding holes, and may be wide enough to cover substantially the entire surface of the above document. But it may be.

When passing the two wires provided on the first sheet through the binding holes of the document and then passing those wires from the tip through the through holes of the second sheet, the protrusions of the wires and the through holes are prevented from coming off. Since the pieces move relative to each other, the second sheet can be moved until the document is sandwiched between the second sheet and the first sheet. Since the protrusion and the retaining piece cannot move relative to each other in the direction in which the wire rod tries to come out of the through hole, the document can be reliably bound between the first sheet and the second sheet. Even if the bound document is thick and the wire protruding from the second sheet is short, the wire does not come out of the through hole, so that the bound state of the document is stably maintained.
If you cut off the excess wire that protrudes from the second sheet after binding the document, the thickness of the document can be added to the thickness of a pair of sheets of the document binding tool, so to arrange it on a document shelf etc. The space required can be minimized. Further, if the wire rod is cut in this way, it is difficult for the bound document to be caught in the adjacent document when it is put in the bookshelf.
Further, each of the above sheets has a length extending substantially over the entire length of the edge of the above document on the side having the binding hole, and since they are bound with the document sandwiched between them, the document is bound. It is possible to prevent the force from concentrating near the binding hole of the document, and the document is less likely to be damaged. The use of such a sheet also prevents the corners of the document (parts away from the binding holes) from bending and thickening or tearing the document. From this point of view, each of the above sheets is required to have a rigidity sufficient to press the edge of the document. However, if the sheet covers almost the entire surface of the document, it is liable to be flexibly deformed, for example, the parts other than the edges of the document are bent away from both outer surfaces of the document so that the document can be viewed. Is desirable.
Since the document binding tool described above has few components and a simple structure, it has an advantage that it is easy to manufacture and can be constructed at low cost.

Regarding the above-mentioned document binding tool, the wire rod has a base end portion having a surface perpendicular to the length direction at the end of the axial portion thereof, and the base end portion is attached to the first sheet. On the other hand, the retaining member having the through hole formed therein may be attached to the second sheet.

Such a document binding tool can be configured as shown in FIG. 1 by utilizing, for example, the binding band 10 shown in FIG. In this case, the base end portion 2a of the wire rod 2 may be attached to the first sheet 4a by adhesive or the like, and the retaining member 3 separated from the wire rod 2 may be attached to the second sheet 4b by adhesive or the like.
Further, as in the binding band 20 shown in FIG. 6, the base end portion 12a of the wire rod 12 can also serve as a retaining member for passing the wire rod 12, and the document binding as shown in FIG. 5 can also be used. You can configure the ingredients. In that case, two binding bands 20 are prepared, one base end portion 12a is attached to the first sheet 14a together with the wire rod 12, and the base end portion 13 of another binding band 20 is separated from the wire rod 12 to prevent it from coming off. It may be attached to the second sheet 14b as a member.
Since inexpensive mass-produced products are commercially available as the binding bands shown in FIGS. 2 and 6, the manufacturing cost of the document binding tool can be suppressed by using them.

Regarding the above-mentioned document binding tool, the outer surface of each of the above sheets (the surface opposite to the side in contact with the document to be bound) is formed flat, and the base end portion of the wire rod and the above-mentioned retaining member are the above-mentioned sheets. It is preferable that it does not protrude from the outer surface of the.
Even when the base end of the wire or the retaining member is attached to the first or second sheet as described above, the inner side surface and the outer surface of each sheet are formed by forming a recess for attachment in each sheet. It is preferable that the sides are flat.

According to the document binding tool configured in this way, the outer surface of each sheet is flat in the state where the documents are bound, so that the documents can be smoothly put in and taken out of the document shelf.
In addition, if the inner surface of each sheet is also formed flat, that surface will be in close contact with the document, so the documents can be bound securely without being damaged, and an extra space will be created between the document and each sheet. Instead, it can be stored compactly on the document shelf. However, with respect to the inner surface, it is also preferable to form a protruding portion (reference numeral 4y in FIGS. 3A and 3B) so as to be inserted into the binding hole of the document.

In the above-mentioned document binding tool, each of the above sheets has a length corresponding to the long side of A4 size paper and a width that can be overlapped only in the vicinity of the binding hole of the above document (about 2 to 6 times the diameter of the binding hole). It is preferable that a groove for folding is provided at a position corresponding to the short side of the A4 size paper.
In the document binding tool 1 shown in FIG. 1 and the like, reference numeral 5 is a groove for such folding.

When binding A4 size documents along their long sides (length 29.7 cm) with the document binding tool configured in this way (so-called vertical binding), each sheet can be used as it is. On the other hand, when binding A4 size documents along the short side (length 21.0 cm) (so-called horizontal binding), each sheet is cut off with the above groove to make the length of the short side. Used in. Regardless of the binding method, the length of the edge of the document along the binding hole and the length of each sheet are almost the same, which makes it easier to handle the bound document and breaks the corners of the document. You can prevent it from bending. In order to enable vertical binding and horizontal binding for documents of other sizes (for example, B4 size and B5 size), the length of each sheet should be set appropriately and a groove for folding should be formed at an appropriate place. good.
Since the width of each sheet is narrowed, it is easy to break off, and it is preferable in terms of reducing the amount of material and reducing the cost.

Regarding the above-mentioned document binding tool, the step between each sheet and the document is relaxed at one edge (ridge angle) along the length direction of the outer surface of each of the above-mentioned strip-shaped sheets (that is, as a so-called chamfer). It is preferable that an inclined surface or a curved surface is formed. In the sheets 4a and 4b shown in FIGS. 3C and 3D, reference numerals 7 and 8 are inclined surfaces or curved surfaces thereof.

According to the document binding tool configured in this way, the bound documents can be smoothly put into the document shelf. The above-mentioned edge (ridge angle) of each of the above-mentioned strip-shaped sheets is a part that easily comes into contact with an adjacent document (or a document binding tool) on the document shelf, but it is said that an inclined surface or a curved surface is formed in that part. This is because it is unlikely to get caught.

In the document binding tool of the present invention, the first sheet has two wire rod mounting holes for attaching the wire rod, and the wire rod and the first sheet are in a separated state in which the wire rod can be integrally attached. , May be. That is, the first sheet and the wire rod are provided to the user in a separated state, and are integrally attached by the user or the like by the user or the like using the above-mentioned wire rod mounting hole before being used as a document binding tool.

If the first sheet and the above wire rod are integrated from the beginning, the length directions of both are at right angles to each other, so the document binding tool can be compactly displayed, sold, or stored in a small package. It's difficult to do. However, if the first sheet and the wire rod are separated as described above, they can be arranged in a nearly parallel state, so that the space required for sales and storage before use can be saved. It is convenient to be able to reduce it. For example, immediately before binding a document, if the wire rod is passed through the wire rod mounting hole of the first sheet and the base end portion thereof is adhered and fixed, a usable document binding tool is completed. As the wire rod, for example, a commercially available cable tie as shown in FIG. 2 or FIG. 6 can be used, so that it is easy to manufacture and the cost can be suppressed.

Further, in the document binding tool of the invention, the second sheet further has two retaining member mounting holes for attaching the retaining member, and the retaining member and the second sheet are integrally integrated. It may be in a separated state that can be attached.

Also in such a document binding tool, as a wire rod and a retaining member, for example, a part in a commercially available cable tie as shown in FIG. 2 or FIG. 6 can be used. For example, immediately before use, the retaining member is separated from the wire, and the wire is attached to the wire rod mounting hole of the first sheet and the retaining member is adhered to the retaining member mounting hole of the second sheet. Such a document binding tool is also easy to manufacture, and the cost can be suppressed.

According to the document binding tool devised, documents can be bound compactly, and it is easy to put them in and out of the document shelf, and even if the documents are repeatedly browsed, the documents will come off or be damaged. Since there is no such thing, documents can be stored in a stable state for a long period of time. Since the number of parts is small and the configuration is simple, there is an advantage that it can be easily manufactured at low cost.

It is a schematic perspective view which shows the document binding tool 1 which is one Embodiment of this invention. It is a top view of the binding band 10 used for the document binding tool 1 of FIG. It is a figure about the sheet 4 used for the document binding tool 1 of FIG. 3 (a) and 3 (b) are a cross-sectional view taken along the line aa and a cross-sectional view taken along the line bb in FIG. 1, and FIGS. 3 (c) and 3 (d) are detailed views of the portion c in FIG. 1 sheet 4a and 2nd sheet 4b are cross-sectional views), and FIG. 3 (e) is a cross-sectional view taken along the line ee in FIG. 1 (that is, a detailed view of the groove 5). It is a top view which shows the state which the document P was bound by the document binding tool 1. It is a schematic perspective view which shows the document binding tool 11 which is another embodiment. It is a top view of the binding band 20 used for the document binding tool 11 of FIG. 7 (a) and 7 (b) show one of the document binding tools 21 configured as an assembly type in which the wire rod 2 and the retaining member 3 are attached to the first and second sheets 24a and 24b from separate states. It is a figure which shows the part. FIG. 7A is a cross-sectional view showing a mounting portion between the sheet 24b and the retaining member 3, and FIG. 7B shows a mounting portion between the sheet 24a and the wire rod 2 (base end portion 2a). It is a cross-sectional view.

Document binding tool 1 according to an embodiment of the present invention is shown in FIGS. 1 to 4.
The document binding tool 1 is a means for binding a plurality of stacked A4 size documents P at the left edge, as shown in FIG. 4, for example. There are two binding holes on the edge of the document P (double punch holes. Generally, two holes with a diameter of about 5 mm are provided at intervals of 8 cm), and the document binding tool 1 The document P is bound by passing the wire rod 2 shown in FIG. 1 and the like through the binding holes, respectively.

As shown in FIG. 1, the document binding tool 1 includes two strip-shaped sheets 4 (first sheet 4a and second sheet 4b), two wire rods 2, and two retaining members 3 through which each wire rod 2 is passed. It is composed of and. Each sheet 4, wire rod 2, and retaining member 3 are all made of plastic (synthetic resin). The wire rod 2 is integrated with the first sheet 4a at the lower part of the drawing by adhering it, and the retaining member 3 is also integrated with the second sheet 4b at the upper part of the drawing by adhering or the like.

The wire rod 2 and the retaining member 3 utilize the binding band 10 shown in FIG. Since a mass-produced product is commercially available as a binding band 10 as shown in the figure, cost reduction can be achieved by using the mass-produced product. By cutting the neck portion on the left side of the drawing, the wire rod 2 and the retaining member 3 can be separated and used.

The wire rod 2 has a shaft-shaped portion having a thickness of 2 to 3 mm and a total length of about 10 cm, and has the same shape as the binding tool described in Patent Document 3 described above. That is, it has a disk-shaped base end portion 2a having a surface perpendicular to the length direction at the right end in the drawing, and the outer diameter gradually expands toward the base end portion 2a on the outer peripheral surface of the axial portion. A plurality of truncated cone-shaped protrusions 2b, which suddenly decrease with each other, are formed at intervals in the length direction of the wire rod 2.

The retaining member 3 used separately from the wire rod 2 has a through hole 3a through which the wire rod 2 is passed, and the inner peripheral surface of the through hole 3a has a shape of a retaining member protruding toward the center of the through hole 3a. Piece 3b is formed. When the wire rod 2 is passed through the through hole 3a, the retaining piece 3b is pushed by the inclined surface of the above-mentioned protrusion 2b having a truncated cone shape and elastically deformed, enabling sliding (relative movement) with the protrusion 2b. On the contrary, even if an attempt is made to pull out the wire rod 2 that has entered the through hole 3a, the retaining piece 3b is caught on the bottom surface (the portion where the diameter is sharply reduced) of the protrusion 2b. It cannot move relative to 3a.

The two sheets 4a and 4b each have a width of 1.5 to 3 cm, a length of 23 to 29 cm, and a thickness of about 2 to 6 mm. Since it has a length close to the long side of A4 size paper and has moderate rigidity, it can hold the entire length not only near the binding hole of the document but also along the edge, so that the corner part of the document can be pressed. Can be prevented from breaking or tearing.

The retaining member 3 and the wire rod 2 described above are integrated with the sheets 4b and 4a in the manner of FIGS. 3A and 3B.
First, FIG. 3A is a cross-sectional view showing a state in which the retaining member 3 is attached to the second sheet 4b. The sheet 4b is provided with holes 4x at positions corresponding to the binding holes of the document P (interval is 8 cm), and a counterbore portion is formed on the upper surface thereof (the surface on the side not in contact with the document P). The retaining member 3 is fitted into the counterbore portion and attached to the sheet 4b using an adhesive. By fitting the retaining member 3 into the counterbore portion, the upper surface (outer surface) of the sheet 4b can be formed flat.
As shown in the figure, a protruding portion 4y surrounding the hole 4x may be provided on the surface opposite to the side on which the retaining member 3 is attached, that is, the surface on the side in contact with the document P. If the outer diameter of the protruding portion 4y is made slightly smaller than the binding hole of the document P, the protruding portion 4y fits into the binding hole of the document P in the bound state, so that the sheet 4b is displaced with respect to the document P. It does not move and is preferable. In the bound state, the lower surface of the sheet 4b is in close contact with the surface of the document P except for the protruding portion 4y. It is also good to prevent the deviation from P.

FIG. 3B is a cross-sectional view showing a state in which the wire rod 2 is attached to the first sheet 4a. A hole 4x is provided in the sheet 4a at a position overlapping the binding hole of the document P (interval is 8 cm), a counterbore portion is formed on the lower surface thereof (the surface on the side not in contact with the document P), and the wire rod 2 is formed in the counterbore portion. The base end portion 2a of the above is fitted and attached to the sheet 4a with an adhesive. Since the base end portion 2a is fitted into the counterbore portion, the lower surface (outer surface) of the sheet 4a is flat. Further, as with the sheet 4b, on the side opposite to the side where the base end portion 2a is attached (the side in contact with the document P), a protruding portion 4y having a diameter slightly smaller than the binding hole of the document P is provided at the position ahead of the hole 4x. Is also preferable. In addition, for the sheet 4a, it is further preferable that the upper surface of the figure, which is in close contact with the surface of the document P, is a satin ground.
As a measure to prevent the positions of the sheets 4a and 4b from shifting on the outer surface of the document P due to the existence of a gap between the binding hole and the wire rod 2, the sheet 4a and 4b are described above. In addition to forming a protruding portion 4y on 4b and making the surface in close contact with the document P a pear ground, a pipe made of resin or the like is fitted inside the binding hole of the document P, and the wire 2 is passed through the inside. There is also a method such as.

The shapes shown in FIGS. 3 (c) to 3 (e) are also given to the first and second sheets 4a and 4b.
FIG. 3C is a cross-sectional view of each sheet 4a and 4b. An inclined surface 7 as a chamfer is formed on one edge portion (ridge angle portion) along the length direction on the outer surface (side not in contact with the document P) of each sheet 4a / 4b. When the documents P are bound using the sheets 4a and 4b so that the inclined surface 7 faces toward the center of the document P (the side that opens without being bound), when the documents P are put into the document shelf, they are placed on another adjacent document or the like. The sheet 4 is hard to get caught and can be inserted smoothly.
There is a similar advantage when the curved surface 8 as shown in FIG. 3D is formed instead of the inclined surface 7.

Further, the grooves 5 shown in FIGS. 1 and 3 (e) are intended to be shortened by folding (cutting) the sheets 4a and 4b at their positions. As described above, the total length of the sheets 4a and 4b is close to the size of the long side of the A4 size, but by breaking along the groove 5, the length of the sheets 4a and 4b can be reduced to the short side of the A4 size. Dimensions (or slightly shorter). Therefore, when binding the long side of an A4 size document or when binding the short side of an A3 size document, use each sheet 4a and 4b as they are, and when binding A4 size documents horizontally, etc. The sheets 4a and 4b are folded at the groove 5 and shortened before use. In either case, the entire length (or almost the entire length) of the edge of the document P can be sandwiched between the sheets 4a and 4b of appropriate length, so that the corners of the document P may be broken, bent, or torn. It can be prevented from doing.

FIG. 4 shows an example of using the document binding tool 1, that is, an example of binding a plurality of A4 size documents P with the document binding tool 1.
The procedure for binding the document P as shown in the figure is as follows. 1) As shown in FIG. 1, the two wire rods 2 integrated with the first sheet 4a are passed through the binding holes provided at the edges of the document P. 2) Align the position of the second sheet 4b to which the retaining member 3 is attached so that the tip of the wire 2 protruding from the upper surface of the document P enters the through hole 3a of the retaining member 3. 3) When the protruding portions 4y shown in FIGS. 3 (a) and 3 (b) are formed on the sheets 4a and 4b, the tips thereof are inserted into the binding holes of the document P. 4) By pressing the second sheet 4b or pulling up the wire rod 2, the wire rod 2 is sufficiently inserted into the through hole 3a of the retaining member 3. 5) The outer surface of the second sheet 4b is made substantially flat by cutting the portion of the wire rod 2 that protrudes from the retaining member 3.

FIG. 4 shows a state in which the edge portion of the document P is sandwiched between the sheets 4a and 4b from the lower surface and the upper surface (both outer surfaces) of the document P in this way. Since the protrusion 2b (same as above) of the wire rod 2 is caught on the retaining piece 3b (see FIG. 2) of the through hole 3a, the wire rod 2 may slide with respect to the retaining member 3 in the direction of loosening the tightening of the document P. not. Therefore, the document binding tool 1 can stably maintain the state in which the document P is bound by being sandwiched between the sheets 4a and 4b.

In the example of FIG. 4, a groove 5 for breaking is formed on the surface of the sheet 4b, and a display 6 such as "A4 horizontal" is attached in the vicinity of each groove 5. When binding the short side of A4 size, the sheets 4a and 4b can be suitably used by folding them in these grooves 5, and the display 6 makes it easy to understand.

FIG. 5 shows a document binding tool 11 using the binding band 20 of FIG. 6 instead of the binding band 10. The binding band 20 of FIG. 6 is made of a soft synthetic resin, and a retaining member 13 having a through hole 13a into which the wire rod 12 can be inserted is provided at a base end portion 12a having a surface perpendicular to the length direction of the wire rod 12. It is formed. The wire rod 12 has a plurality of sawtooth-shaped (triangular wavy) protrusions 12b that are similar to the receiving claws of the string body described in Patent Document 2, that is, the thickness gradually increases and rapidly decreases toward the base end portion 12a. Have on the surface. The retaining member 13 has a through hole 13a, and a retaining piece 13b is formed on the inner peripheral surface thereof toward the center of the through hole 13a. When the wire rod 12 is passed through the through hole 13a, the wire rod 12 moves only in the direction of being inserted into the through hole 13a from the tip end portion 12a due to the action of the protrusion 12b and the retaining piece 13b.

In the document binding tool 11 of FIG. 5, a binding band 20 including a wire rod 12 is attached to one of the first sheet 14a of the pair of sheets 14 by fixing the base end portion 12a, and is attached to the other second sheet 14b. , A retaining member 13 separated from the wire rod 12 of another binding band 20 is attached. Such a document binding tool 11 can also be configured in the same manner as the document binding tool 1 shown in FIG. 1 and the like, and can be used in the same manner to appropriately bind the document P.

In the document binding tool 1 shown in FIGS. 1 to 4, the wire rod 2 is integrated with the first sheet 4a and the retaining member 3 is integrated with the second sheet 4b from the time of manufacture. The same applies to the document binding tool 11 of FIGS. 5 and 6. However, it is possible to leave them unintegrated at the time of manufacture.
That is, the wire rod 2 (or 12) and the retaining member 3 (or 13) are made into separate parts from the sheets 4a / 4b (or 14a / 14b), and the user integrates the above before use. So to speak, it is configured as an assembly-type document binding tool. FIG. 7 shows that for such an assembly-type document binding tool 21, the retaining member 3 in the separated state and the second sheet 24b are integrated, and the wire rod 2 and the first sheet 24a, which are also in the separated state, are integrated. It is sectional drawing which shows about the integration.

As shown in FIG. 7 (a), in the second sheet 24b of one of the pair of sheets 24, a recess 23 capable of accommodating the retaining member 3 is formed on the outer surface, and a through hole 23a for the wire rod 2 is formed. It is formed in the center of the bottom of the recess 23. Further, as shown in FIG. 7B, in the other first sheet 24a, a recess 22 for accommodating the base end portion 2a of the wire rod 2 is formed on the outer surface, and a through hole 22a for the wire rod 2 is formed in the recess 22a. It is formed in the center of the bottom of the.
