Description

The present invention is an optical fiber or optical fiber as an object to be held was routed to the required state, when placing is held again and again relates shall be maintained.

For example, optical fibers such as optical fiber cores, optical fiber tape cores, and optical fiber strands are very thin, and as is well known, they are easily broken by bending or lateral pressure. Since the optical transmission characteristics may be affected by the pressure and lateral pressure, it must be handled with care. However, as a holder used when the optical fiber is held in a desired position or a plurality of optical fibers are bundled, a conventionally known belt-like holder 100 (disclosed in FIG. 15) is used. It is the present condition (patent document 1). The holder 100 is formed by covering a metal core wire 101 (for example, 0.4 mm diameter) that can be plastically deformed with fingers, such as a thin steel wire, with a synthetic resin coating material 102 formed of vinyl chloride or the like. It is formed in a band shape, and is widely used for bundling electrical cords in addition to optical fibers. As shown in FIG. 15, the holder 100 swells to the side of one side of the belt-like portion 103, which is a portion in which the synthetic resin coating material 102 is formed in a belt-like shape. It has a core wire embedded portion 104 formed as a protrusion extending along the center in the width direction (cross-sectional longitudinal direction) of the strip portion 103 over the entire length in the longitudinal direction. The metal core wire 101 is embedded in the core wire embedded portion 104 and extends over the entire length of the holder 100.
Japanese Patent Laid-Open No. 11-1263

  However, in the above-described holder 100, the synthetic resin coating material 102 is generally made of a hard resin such as vinyl chloride, and is too hard to bend. Therefore, a thin wire (optical fiber core wire, tape) There was dissatisfaction that the ability to bind and hold was low. In addition, there has been a complaint that it is difficult to adjust the force at the time of binding, such as damage to the optical fiber coating due to excessive tightening, or when the fixing function is required, the tightening force is too loose to perform the fixing function. In many cases, the side where the core wire embedded portion 104 is used is used as the side where the optical fiber is contacted. In this case, the binding force of the holder 100 is concentrated on the contact position of the core wire embedded portion 104 in the optical fiber. May damage the optical fiber.

The present invention has been made on the basis of the above circumstances. The object of the present invention is to hold an object to be held firmly with an appropriate holding force, and to hold the object to be held with an excessive holding force. It is an object of the present invention to provide a holder that can avoid inconveniences such as damage.

In order to achieve the above object, the present invention has a resin outer body made of a soft resin that covers the entire flexible metal core formed in a plate shape, and the entire resin outer body is the soft resin layer. The resin sheathing body can be bent into a desired shape for holding an object to be held, which is an optical fiber or an optical fiber core, by plastically deforming the metal core. A first soft resin layer that is a soft resin layer deposited on one surface of the metal core and a second soft resin layer that is a soft resin layer deposited on the other surface of the metal core; The first soft resin layer and the second soft resin layer are made of a compressible foamed synthetic resin material, the first soft resin layer is made of foamed polyethylene, and the second soft resin layer is made of foamed rubber. Provide a retainer.
In addition, this holder can also be set as the structure which made the thickness of the said foaming polyethylene layer larger than the said foaming rubber layer .
In the present invention, the metal core material is formed in a shape having a base portion and one or more tongue-like branch portions extending from the base portion, and the soft resin layer is formed on both surfaces of the metal core material. And a holder base portion having a structure in which the soft resin layer is attached to both surfaces of the base portion of the metal core material, and the soft resin layer is attached to both surfaces of the branch portion of the metal core material. And a long and narrow holding piece extending from the holding base portion. In this case, the holding pieces are arranged opposite to both sides of the holder base portion, and the holding pieces arranged on both sides of the holder base portion are formed by holding pieces on both sides or one side of the holder base portion. When bent toward the opposite side through the holding base, the holding piece on one side of the holding base is secured between the holding pieces on the other side of the holding base. The position may be shifted so as to enter the gap .

According to the holder of the present invention, since the soft resin layers are provided on both sides of the plate-shaped metal core material, damage is not caused by local concentration of stress on the object to be held. A holding force can be sufficiently applied while maintaining a desired shape, and the object to be held can be fixed stably. Furthermore, if a soft resin layer is provided so as to cover the entire plate-shaped metal core material, the metal core material is not exposed to the outside of the holder, for example, a problem such as damage to an object to be held such as an optical fiber. Can be reliably prevented. Further, by using the compressibility of the foamed synthetic resin materials as the material of the soft resin layer, it can be prevented reliably disadvantage damaged by local stress concentration of the held object, the retentate by bending the retainer When the material is sandwiched and held, the pressing force acting on the object to be held is stabilized by the compressed foamed synthetic resin, and the object to be held can be held with a desired pressing force. Further, if the holder has a holder base portion and an elongated holding piece extending from the holder base portion, the holder base portion can be used for fixing to a fixed object .

The best mode for carrying out the present invention will be described below with reference to the drawings.
First, a first embodiment of a holder according to the present invention will be described.
As shown in FIG. 1A, the holder 1 is formed in a band shape as a whole, and a metal core material 2 made of a flexible metal formed in a plate shape, and the entire metal core material 2 It is comprised from the resin exterior body 3 to cover.
The metal core material 2 is formed of a flexible metal that can be bent (plastically deformed) by fingers, such as copper and aluminum. The shape can be maintained.

  As shown in FIG. 2, the resin outer package 3 includes a soft resin layer 3 a (hereinafter also referred to as a first soft resin layer) attached to one surface (first core material surface 2 a) of the metal core material 2. And a soft resin layer 3b (hereinafter also referred to as a second soft resin layer) attached to the other surface (second core material surface 2b) of the metal core material 2 (see FIG. 2). . The first soft resin layer 3 a wraps around the outer peripheral surface (end surface 2 c) of the metal core material 2 from the first core material surface 2 a of the metal core material 2, and the second soft resin layer 3 b is the second soft resin layer 3 b of the second metal core material 2. The outer periphery 2c (end surface) of the metal core member 2 is wound from the core member surface 2b, and the joint 3j between the soft resin layers 3a and 3b surrounds the metal core member 2 so that the entire outer periphery of the metal core member 2 is surrounded. It is formed over the circumference. Adhesion between the first soft resin layer 3a and the second soft resin layer 3b can employ, for example, adhesion using an adhesive or adhesive fixing with a double-sided tape (tape having adhesive surfaces on both sides) interposed therebetween.

As described above, the bonding between the soft resin layers 3a and 3b is not limited to the form in which the outer peripheral portions of both the soft resin layers 3a and 3b are respectively wound around the outer peripheral surface 2c (end surface) of the metal core member 2 and bonded. For example, the joining surface 3d of the second soft resin layer 3b has a shape that extends flush with the second core material surface 2b of the metal core material 2, and the metal core material of the first soft resin layer 3a with respect to the joining surface. Various forms such as a configuration in which a portion protruding around 2 is bonded can be adopted. However, the positions of the joint portions between the soft resin layers 3 a and 3 b avoid the first surface 1 a and the second surface 1 b which are both surfaces of the belt-shaped holder 1. The first surface 1a and the second surface 1b are surfaces that come into contact with the objects to be held when the objects to be held are held (gripped or stored so as to be surrounded from the surroundings) by the holder 1 (details will be described later). ), If the configuration is such that the joint portion 3j between the soft resin layers 3a and 3b is located away from the first surface 1a and the second surface 1b, contact of the joint portion with the object to be held can be avoided. The inconvenience of damaging the object to be held can be prevented.
The soft resin layers 3a and 3b may be formed with grooves for housing the metal core material 2, but for example, when a foamed resin material having cushioning properties (compressibility) is employed as described later, Depending on the flexibility of the soft resin layers 3a and 3b themselves without forming a shape having a groove for storing the metal core material 2, the circumference of the metal core material 2 of one or both of the soft resin layers 3a and 3b The protruding portions may be wound around the outer peripheral surface 2c of the metal core member 2 and bonded and fixed together to be integrated.
The soft resin layers 3a and 3b are bonded and fixed to the metal core material 2 by, for example, bonding with an adhesive or heat welding.

Here, the soft resin is a resin having a flexural modulus of 68.64655 MPa or less (700 kgf / cm 2 or less: defined by ASTM D 883).
In the present embodiment, a foamed synthetic resin material having cushioning properties (compressibility) is employed as the first and second soft resin layers 3a and 3b (hereinafter, the soft resin layer is also referred to as an elastic exterior material). The use of a foamed synthetic resin material, which is a soft resin, is preferable in that it is difficult to damage the object to be held when holding the object such as an optical fiber or a glass substrate. The materials and thicknesses of the first and second elastic exterior members 3a and 3b may be the same as each other, but may be different. Here, as a preferred example, one of the elastic exterior materials (here, the first elastic exterior material indicated by reference numeral 3a) has a compressible foamed polyethylene, and the other elastic exterior material (here, the second elastic exterior material indicated by reference numeral 3b) is foamed. The structure using rubber is illustrated. In addition, the thickness of the foamed polyethylene layer that is the first elastic exterior material 3a is larger than that of the foamed rubber layer that is the second elastic exterior material 3b. The thickness of the elastic sheathing material is set in view of prevention of damage when holding and fixing an object to be easily damaged such as an optical fiber or a glass substrate, bending operability of the holder 1, etc. The foamed polyethylene used for the soft resin layer 3a is 4 mm, and the foamed rubber used for the soft resin layer 3b is 2 mm.

FIG. 1 (b) shows an example of holding (holding here) the object 4 to be held using the holder 1. Here, an optical fiber is employed as the object to be held 4, and the object to be held 4 is hereinafter sometimes referred to as an “optical fiber”. The optical fiber 4 employed here is, for example, an optical fiber, an optical fiber core (single or multi-core), an optical fiber cord, or the like.
The holder 1 is extended along the first core surface 2a of the metal core member 2 by the first elastic exterior member 3a at a bent portion 1e set in a part of the holder 1 in the longitudinal direction. One of the second surfaces 1b formed so as to extend along the second core material surface 2b of the metal core material 2 by the first surface 1a and the second elastic exterior material 3b formed by By bending the holding tool 1 so that the inner side and the other side become the outer side, both side portions (specifically, the inner side of the bending portion 1e is bent) via the bent portion 1e in the holding tool 1. The object to be held can be gripped by being sandwiched between the bent portions 1e of the elastic exterior material. Here, both sides of the holder 1 function as holding portions 1c and 1d for sandwiching the object 4 to be held via the bent portion 1e.

  In the example of FIG. 1 (b), the first elastic sheath is a foamed polyethylene layer at the bent portion 1e set at the center of the longitudinal direction of the holder 1 (the direction of arrow L in FIG. 1 (a)). The material 3a is bent so as to be inside (that is, the first surface 1a is inside), and is folded in half, and the optical fiber 4 that is the object to be held is sandwiched and held by the first elastic sheathing material 3a from both sides. For example, if the holder 1 is attached to an optical fiber storage tray, a wiring shelf of a frame such as an optical distribution board, and the optical fiber 4 is gripped by bending the holder 1 as described above, The holder 1 can function as a fastener for the optical fiber 4 or the like. Further, FIG. 1 (c) ensures that the plurality of holders 1 attached as a plurality of optical fiber retainers to an optical fiber storage tray or a wiring shelf of a frame such as an optical distribution board are wound in a circular shape. An example is shown in which the extra length 4a of the optical fiber 4 is gripped and functioned as a curvature maintaining member that maintains the curved state of the extra length 4a.

  When holding the object to be held by the holder 1, the holder 1 is bent so that the object to be held is inside the bent portion of the bent portion, and is positioned on both sides via the bent portion of the holder 1. The parts are pressed together, and the elastic exterior material inside the bend is compressed and deformed. When the object to be held is a thin line like the optical fiber 4, the object to be held is embedded between the elastic sheathing materials on both sides due to the compressive deformation of the elastic sheathing material on both sides of the object to be held. The held object 4 is held from the surrounding elastic exterior materials 3a and 3b with a substantially equal pressing force. Moreover, in this holder 1, when the holding of the object to be held is completed, the bent shape is maintained by the plastically deformed metal core material 2, so that the compression state of the elastic exterior material is also maintained and compressed and deformed. Since the state in which the pressing force is applied to the object to be held from the elastic exterior material is also maintained, there is an advantage that the holding state of the object to be held can be stably maintained. Needless to say, it is possible to prevent the inconvenience that the elastic exterior material functions as a cushioning material and damages the object to be held by excessive pressing force during the gripping operation.

  Further, in the present embodiment, when holding the object to be held such as the optical fiber 4, the bending of the holder 1 at the bent portion 1 e is performed (bending). The orientation may be such that the second surface 1b is on the inside. The second surface 1b, that is, the soft resin layer 3b (elastic exterior material) made of foamed rubber may be pressed against each other to hold the object to be held. When the object to be held such as the optical fiber 4 is gripped at the place where the holder 1 is bent with the second elastic exterior material 3b inside, since the anti-slip effect is obtained by the friction coefficient of rubber, the object to be held is moved. Suitable for fixing so that there is no.

In this embodiment, the holder 1 is bent at the position of the bent portion 1e and held in contact with the optical fiber 4 by the compression action of the soft resin layers 3a and 3b.
For example, the optical fiber 4 may be held inside the holder 1 curved in an annular shape. In the present invention, even when an object to be held such as the optical fiber 4 is accommodated inside the holder so as to be freely movable with a slight clearance, it is referred to as “holding”.

  In the present embodiment, copper or aluminum is used as the flexible metal that forms the band-shaped metal core 2. However, other metals may be selected in consideration of workability during bending. Moreover, about the shape of the metal core material 2, it is good also as a shape which considered the workability at the time of bending deformation, such as using a mesh-shaped flat plate, for example.

FIG. 3A shows the inner side of the bending of each of the bent portions 1h, 1i, and 1j by bending (folding) the holder 1 with the bent portions 1h, 1i, and 1j provided at three locations in the longitudinal direction of the holder 1. An example in which the optical fiber 4 that is the object to be held is sandwiched and held is shown.
The bent portions 1h, 1i, and 1j of the holder 1 are provided by selecting any location in the longitudinal direction of the holder 1, and the bent portions 1h and 1j are arranged such that the first surface 1a is on the inside. The bent portion 1i is bent so that the second surface 1b is on the inner side. At this time, each portion in the longitudinal direction of the holder 1 that is bent and butted against the bent portions 1h, 1i, and 1j functions as the holding portions 1k, 1m, 1n, and 1p. Here, the optical fiber 4 is sandwiched and held between the holding portions 1k and 1m and the holding portions 1n and 1p by the soft resin layer 3a made of foamed polyethylene.
3B and 3C, the optical fiber 4 may be sandwiched between the holding portions 1m and 1n and held by the soft resin layer 3b made of foamed rubber. Accordingly, as described above, the object to be held which is easily influenced by external force such as an optical fiber or an optical fiber core is a soft resin layer between the holding portions 1k and 1m and between the holding portions 1n and 1p. The object to be held that is held by 3a and is relatively unaffected by external force can be selected as appropriate, for example, held by the soft resin layer 3b between the holding portions 1m and 1n.

  As described above, according to the first embodiment of the holder according to the present invention, the object 4 to be held is either one of the elastic exterior members 3a and 3b made of soft resin on both surfaces of the metal core 2. Because it is configured to be pressed and gripped, it does not damage the object to be held due to local stress concentration, etc., and it can hold the bent shape sufficiently to keep the object to be held in a stable manner. Can be fixed. That is, in this holder 1, the gripping force for gripping the object to be held 4 acts as a pressing force from the elastic exterior material compressed and deformed between the metal core members 2 of the holding parts on both sides of the bent part. In addition, since the plate-like (band-like in this embodiment) metal core material 2 of both holding portions keeps the parallel state of each other, a compressive force is applied to the elastic exterior material. As a result, the elastic exterior material Therefore, the gripping force (pressing force) acting on the held object 4 acts evenly on the held object 4 without causing local uneven distribution, and there is no concern that the held object 4 is damaged. Further, according to the holder 1, the entire metal core 2 is covered with the resin sheathing 3 and there is no portion where the metal core 2 is exposed. It is possible to surely prevent inconveniences such as the object to be held being brought into contact and being damaged.

Next, a second embodiment of the holder according to the present invention will be described.
As shown in FIG. 4, the holder 1 </ b> A in the present embodiment is a plate-shaped metal core material 2 (hereinafter, for distinction, the metal core material according to this embodiment may be described using reference numeral 21). And it is the same as the first embodiment in that it has a resin sheathing body 3 that is attached to the outside of the metal core material 21 and covers the entire metal core material 21 so as not to expose the metal core material 21. The metal core material 2 (21) having a plate-like base portion 21a and a plate-like tongue piece 21b extending from the base portion 21a is used, and the overall shape is also a plate-like holder in accordance with the shape of the metal core material 21. The second embodiment is different from the first embodiment in that it has a shape having a base portion 11 and an elongated plate-like holding piece 12 extending from the holder base portion 11.
Since the material of the metal core material 21 and the material of the two elastic exterior materials 3a and 3b attached to both sides of the metal core material 21 can be the same as those in the first embodiment, description thereof is omitted. Moreover, it is the same as that of 1st Embodiment that the resin exterior body 3 joins and integrates the elastic exterior materials 3a and 3b of the both sides of the plate-shaped metal core material 21 of 1 sheet. . This also applies to the following embodiments.

4 (b) and 4 (c) are usage examples of the holder 10. FIG. In this example, the holder 1 </ b> A is bent so that the holder 12 is overlapped with the holder base 11 by a bent portion 11 a set near the boundary between the holder base 11 and the holder 12, and the holder base 11 is bent. The optical fiber 4 as the object to be held is sandwiched between the holding piece 12 and the holding piece 12.
4B and 4C, the first elastic exterior member 3a extends along the metal core 21 by the first elastic exterior member 3a on the inner side, that is, on both surfaces of the plate-like holder 10 as a whole. The holding piece 12 is bent so that the first surface 1a formed so as to be inside, but the holding piece 12 is bent when the second elastic exterior material 3b is inside, that is, the first surface 1a. The second surface 1b on the opposite side may be on the inside.

  Fig.5 (a) is the figure which hold | maintained the some optical fiber 4 collectively using the holder 1A in this embodiment. Here, the plurality of optical fibers 4 are arranged and held in parallel between the holder base portion 11 and the holding piece 12.

  FIG. 5 (b) shows the structure of a frame such as an optical fiber storage tray or an optical distribution board using the holder 1A according to this embodiment, as in the first embodiment shown in FIG. 1 (c). A bending maintaining member that holds the extra length 4a of the optical fiber 4 secured in a state where a plurality of holders 1A attached to the wiring shelf or the like as optical fiber retainers are wound in a circular shape and maintains the curved state of the extra length 4a. As an example.

  Here, when fixing the holder base portion 11 to a fixing object such as a pillar, fixing with an adhesive or a double-sided adhesive tape may be used, and a screw hole is provided at an appropriate position of the holder base portion 11. It may be screwed to the fixed object. About a fixing method, it can select suitably according to the condition of the place where 1 A of holders are used. In the case of the holder 1A, the holder base portion 11 is a plate shape that is considerably larger than the holding piece 12 (the dimension in the surface direction is large), so the holder base portion 11 is fixed with an adhesive or a double-sided adhesive tape. When fixing to an object, a sufficient bonding area can be secured and a sufficient fixing force can be obtained. In addition, fixing by screwing or the like has an advantage that a fixing position (for example, a screw use position) can be set at a position that does not interfere with the object to be held by screwing the holder base portion 11 to the object to be fixed. .

  In addition, the following 3rd-7th embodiment is a thing of the form from which the several holding piece protruded from the holder base part. The shape of the holder according to the present invention corresponds to the shape of the metal core material.

Next, a third embodiment according to the holder of the present invention will be described.
As shown in FIG. 6 (a), the holder 1B in the present embodiment has a holder base in which three holding pieces 12a, 12b, 12c are skewered in the longitudinal direction (FIG. 6 (a) left-right direction). The shape extends from the portion 11. The material of the metal core member 22 and the material of the two elastic exterior members 3a and 3b attached to both sides of the metal core member 22 can be the same as those in the first embodiment, so that the description thereof is omitted. To do. Moreover, it is the same as that of 1st Embodiment that the resin exterior body 3 joins and integrates elastic exterior material 3a, 3b of the both sides of the metal core material 22. FIG.

The metal core member 22 is a plate-like member having a plate-like base portion 22a and plate-like tongue pieces 22b, 22c, and 22d extending in parallel from the base portion 22a. Covered with body 3. The resin armor 3 is composed of an elastic armor 3a that forms the first surface 1a and an elastic armor 3b that forms the second surface 1b.
A base portion 22a formed on the metal core member 22 is accommodated in the holder base portion 11, and holding pieces 12a, 12b, and 12c extend in parallel from the holder base 11, respectively. It is formed. Here, a tongue piece 22b formed on the metal core material 22 is accommodated in the holding piece 12a. Similarly, a tongue piece 22c is accommodated in the holding piece 12b, and the holding piece 12c A tongue piece 22d is housed inside.

  Also in this embodiment, one or a plurality of the three elongated holding pieces are bent at the center in the longitudinal direction or near the boundary between the holding piece and the holder base 11. A holding form in which the optical fiber 4 is sandwiched by being folded back to the holder base portion 11 side can be employed. However, in the holder 1B of the present embodiment, for example, as shown in FIG. Further, when holding the object to be held (optical fiber) using three holding pieces arranged side by side in the longitudinal direction, the holding piece 12b located at the center passes through the object to be held (optical fiber). Thus, a pressing force is applied to the object to be held from the opposite side of the holding pieces 12a and 12c on both sides of the holding piece 12b, and the optical fiber 4 is connected by the central holding piece 12b and the holding pieces 12a and 12c on both sides. From both sides Holding form that lifting can also be employed. Specifically, in the example shown in FIG. 6C, among the three holding pieces arranged side by side, the holding piece 12 b located at the center is bent near the boundary with the holder base portion 11. The positions of the holding pieces 12a and 12c on both sides extending so as to extend the holding part base part 11 from the holding tool base part 11 made flat are slightly shifted, and the holding piece 12b in the center is provided with the optical fiber 4. Is pressed from the opposite side of the pair of holding pieces 12a, 12c on both sides.

  However, the holding piece 12b at the center is provided on both sides so that the inner tongue piece 22c (metal core material) is parallel to the tongue pieces 22b and 22d (metal core material) of the holding pieces 12a and 12c on both sides. Since they are arranged in parallel with 12a and 12c, when holding a plurality of optical fibers 4 arranged side by side, each optical fiber 4 can be held with an equal pressing force. The central holding piece 12b is bent by bending the holding pieces 12a, 12c on both sides without bending the central holding piece 12b, or by bending all three holding pieces (12a, 12b, 12c). It is also possible to realize a shape for holding the optical fiber 4 between the holding pieces 12a and 12c on both sides thereof. Further, the work of holding the optical fiber 4 between the central holding piece 12b and the holding pieces 12a, 12c on both sides thereof may be realized by bending the holding piece. After the molding is completed, the optical fiber 4 is inserted between the holding piece 12b at the center and the holding pieces 12a and 12c on both sides thereof from the leading end side of each holding piece protruding from the holder base portion 11. It is also possible.

  In this example, the optical fiber 4 is not firmly fixed so as not to be displaced, but the optical fiber 4 is held lightly, and the optical fiber 4 is allowed to move when the optical fiber 4 is strongly pulled. It is excellent as a holder for optical fibers in that the fiber 4 is not damaged. Further, the optical fiber 4 held between the central holding piece 12b and the holding pieces 12a and 12c on both sides of the holding piece 12b has an advantage that it can be easily taken out from the holder 1B simply by bending the holding piece.

FIG. 6D shows an optical fiber retainer for an optical fiber storage tray or a wiring shelf of a frame such as an optical distribution board as in the embodiment shown in FIGS. 1C and 4D. This is an example in which a plurality of holders 1B attached are functioned as a curve maintaining member that holds the extra length 4a of the optical fiber 4 secured in a circularly wound state and maintains the curved state of the extra length 4a.
Other details such as a method of fixing the holder 1B to the fixed object are the same as those described in the second embodiment, and the description thereof is omitted.

Next, a fourth embodiment of the holder according to the present invention will be described.
Reference numeral 23 denotes a plate-shaped metal core, in which 23a is a base portion, and 23b, 23c, and 23d are tongue pieces.

  As shown in FIG. 7A, the holder 1C in this embodiment is a third embodiment in that a plurality of holding pieces 12d, 12e, and 12f extending in a tongue shape from the holder base portion 11 are formed. In this embodiment, two holding pieces 12d and 12f are formed to extend in parallel with each other from one side of the holder base portion 11, while the holder base portion 11 is interposed therebetween. The difference is that a holding piece 12e is formed to extend from a side opposite to the one side. Further, for example, as shown in FIG. 7 (c), the holding pieces 12d, 12f, and 12e on both sides that face each other through the holding base portion 11 can be bent by holding the holding pieces on both sides or on either side. The position is shifted in the lateral width direction (vertical direction in FIG. 7A) of the holder 1C so that the holding piece 12e can be inserted into the gap secured between the holding pieces 12d and 12f.

  When the holding piece 12e extending from one side of the holder base portion 11 is bent to the opposite side facing the holder base portion 11, the holding piece 12e is placed on the other side with the holder base portion 11 in between. It enters the gap secured between the holding pieces 12d and 12f. Similarly, even when the holding pieces 12d and 12f are bent to the opposite side opposite to each other with the holder base portion 11 in between, the holder base is placed in the gap secured between the holding piece 12d and the holding piece 12f. A holding piece 12e formed on the other side of the part 11 is inserted. That is, the holder 1C is formed so that the positions of the holding pieces 12d and 12f and the holding piece 12e extending from the holder base portion 11 are shifted so as not to overlap each other.

  As shown in FIG. 7C, as described above, the holding pieces 12d, 12f and 12f extending from the opposite sides across the holding base 11 are bent or the holding pieces on both sides are bent, thereby holding the holding pieces 12d.
