Description

  The present invention relates to a staple holding tool for holding a staple used when wiring an insulated wire.

  Conventionally, a staple holding tool for holding a staple used when wiring an insulated wire is widely known. For example, it is widely known including a staple holder (steple fixture) disclosed in Patent Document 1.

The staple holder shown in Patent Document 1 is configured as follows based on the description.
“We have two large and small parallel grooves at the tip of the main body, and selectively insert a corresponding size of staple into one of these grooves, and fix the insulated wire to the main body to which the staple is attached. Bring the insulated wire between the two nail members of the staple, hit the head of the staple with a hammer, and strike about half of the two nails of the staple. After that (after driving), the main body is removed from the staple and the remaining staples can be driven in. "

Japanese Utility Model Publication No. 7-23938

This conventional staple holder is convenient when a thin insulated wire is fixed with a small staple.
That is, when a small staple is used, if a small staple is picked up and supported by a fingertip and a hammer is driven down with a small staple, the fingertip is often accidentally hit and damaged. Conventional products are useful for solving such problems.

However, with this conventional staple holder,
(1) Since the groove widths of the two large and small grooves for holding the stapler are fixed, it is necessary to adapt to the stapler with various thicknesses (wire diameters) of the nail members in the stapler in the field. There is a problem that becomes practically difficult.
(2) In addition, when attaching an insulated wire to a wall, it is necessary to attach an insulated wire that is heavy and twists and bends to the wall and holds it in a certain place. However, in the configuration described in Patent Document 1, when holding the main body with one hand and the hammer with the other hand, there is no way to hold an insulated electric wire that is heavy and twists and bends easily. There is a problem that must be.
(3) In many cases, the upper portions of the two nail members of the staple are surrounded by an insulating member. Moreover, it is thicker in order toward the top. Therefore, when the groove width is fixed as in Patent Document 1, the upper insulating member of the two nail members of the staple is bent and damaged in the process of hitting the head of the staple with a hammer. There were problems such as danger.

The object of the present application is to solve the above-described problems, and to provide a holding tool that can hold not only small steps but also large steps.
Another object of the present invention is to provide a staple holding tool capable of holding a staple nail member so as to be driven substantially perpendicular to the construction surface when the clamped staple is driven toward the construction material.
Another purpose is that when an insulated wire is arranged on a vertical wall, by supporting one clamping member with one hand, it is possible to drive the staple while holding both the staple and the insulated wire properly. An attempt is made to provide a staple holding tool.
Other problems, objects and advantages will be readily apparent from the drawings and the following description associated therewith.

The main body 1 of the staple holding tool S in the present invention is:
A first clamping member 2 and a second clamping member 3 that are arranged freely at a distance from each other are provided, and a first opposing surface 8 and a second opposing surface between these two clamping members 2 and 3. 9, the two nail members 27, 27 of the staple 26 can be clamped from both sides in a state where the two nail members 27, 27 are attached to the opposing surfaces 8, 9, respectively. The opposing surface 8 is provided with a first nail member clamping part 13 and a second nail member clamping part 14,

The back surfaces 2b and 3b of the two clamping members 2 and 3 can be fitted with the insulated wires 33 to be fastened by the staple 26 in a state where they extend over the two clamping members 2 and 3, respectively. The opened groove-like wire receiving grooves 4 and 5 are provided so as to become longer in the direction substantially perpendicular to the facing surfaces 8 and 9, respectively. In the two wire receiving grooves 4 and 5, The side-side groove walls 4c and 5c on one side are wire attachment walls 4c and 5c, respectively, to which wires can be attached,

  Of the two clamping members 2 and 3, the first nail member clamping part 13 and the second nail member clamping part 14 provided on the opposing surface 8 of one clamping member 2 have the above-mentioned wire attachment wall. With the position of 4c as a boundary, the first nail member clamping portion 13 is provided on the side of the wire receiving groove on one side with the opposed surface 8 being concave, and the other of the positions of the wire attachment wall 4c is provided. A second nail member clamping part 14 is provided near the side, and the concave part 11 of the first nail member clamping part 13 accepts the position of the nail members 27, 27 corresponding to the size of the staple 26. It is wide so that it can change in the width direction of the groove,

  The second nail member clamping portion 14 is a concave groove 10 that opens the end portions 10a and 10b on the front surface and the rear surface. The bottom of the groove 10 is narrow so that it can be accommodated even if there is a change, and the depth 10e of the concave groove 10 is such that the diameter of the nail members 27 and 27 in the large and small staples 26 is small. The depth corresponds to the diameter,

  Further, the two clamping members 2 and 3 are urged in a direction (22) in which the opposed surfaces 8 and 9 opposed to each other are always close to each other.

  More preferably, the second nail member clamping portion 14 has a ditch 10 in a state of projecting toward the other clamping member 3 between the concave groove 10 and the concave first nail member clamping portion 13. Any device provided with the over-prevention member 12 may be used.

Also preferably, the depth dimension of the concave groove of the second nail member clamping portion is such that the diameter of the nail member in the large and small staples is smaller than the thin diameter dimension, and A portion of the second nail member clamping portion 14 facing the groove 10 is provided with a groove 10g as a third nail member clamping portion (see FIGS. 13B and 13C). 10g is a concave groove whose end is opened on the front and back surfaces, and the cross-sectional shape of the concave groove 10g enables the corresponding reception even if the diameter of the nail member 27 of the staple 26 changes. Further, the depth dimension 10h of the concave groove 10g as the third nail member clamping portion is the same as the depth dimension 10e of the concave groove of the second nail member clamping portion 14, 3 is the sum of the depth dimension 10h of the groove 10g as the nail member clamping part,
The nail member 27 in the large and small staples 26 may have a diameter corresponding to a thin diameter.

As described above, according to the present invention, the two clamping members 2 and 3 are arranged freely in perspective, and the clamping members 2 and 3 always approach the nail member clamping portions 9, 13, and 14 to be opposed to each other. Since the direction is biased in the direction, there is a feature that even if the diameter of the nail members 27, 27 of the staple 26 changes in size, the gap between the two clamping members 2, 3 can be widened.
This has an operational effect that can cope with the change in size of the staple 26 corresponding to the thickness of the insulated wire.

  Moreover, in the present invention, as described above, even when the diameters of the nail members 27 and 27 of the staple 26 are changed in size, the second nail member sandwiching portion 14 has the end portions 10a and 10b. The groove 10 is open to the front and back surfaces, and the cross-sectional shape of the groove 10 is narrow so that it can be received even if the diameter of the nail members 27, 27 of the staple 26 changes in size. In addition, the depth dimension 10e of the concave groove 10 is such that the diameter of the nail members 27, 27 in the large and small staples 26 corresponds to a narrow diameter dimension. As can be understood, even if there is a change in the diameter of the nail members 27, 27, the outer peripheral surface of any of the nail members 27, 27 is always held at three or more points. The nail members 27 and 27 can be held almost vertically, and the driving operation of the staple 26 is correct. There is an effect on the work that can be performed.

Furthermore, when the wire attachment surface 40 is a vertical surface as shown in FIG. 11, the free end 33a of the insulated wire 33 that has not yet been fixed hangs downward from the planned wiring position due to its own weight. There is.
However, in the present invention, it is possible to store the insulated wires 33 to be fastened by the staple 26 in a state of extending over the two clamping members 2 and 3 on the back surfaces of the clamping members 2 and 3, respectively. Concave groove-shaped wire receiving grooves 4 and 5 that are open at both ends are provided so as to be elongated in a direction substantially perpendicular to the opposed surfaces 8 and 9, respectively, and the two wire receiving grooves are 4 and 5 are side wall grooves 4c and 5c on one side of each side, and are wire attachment walls 4c and 5c to which wires can be attached (attached reference surfaces),
In addition, in the first and second nail member sandwiching portions 13 and 14, the first nail member sandwiching portion 13 is formed on the side of the wire receiving groove on one side with the wire attaching wall 4c as a boundary. Is provided in a state in which the facing surface 8 is recessed, and the second nail member clamping portion 14 is provided on the other side of the wire attachment wall 4c.
When the insulated wire 33 is wired on a vertical surface, the insulated wire 33a that is about to hang down is received by the wire attachment wall 4c of the wire receiving groove 4 on the back surface of the holding members 2 and 3 held by one hand, As can be understood from FIG. 11, the insulated wire 33 is stopped at a predetermined position, and in this state, the first and second nail member sandwiching portions 13, which are at a predetermined distance from the insulated wire 33 in advance, 14 has the effect of being able to accurately drive the two nail members 27 and 27 of the staple 26 on both sides of the insulated wire by holding the hammer with one of the remaining hands.
As described above, this means that the operation that conventionally required two hands is performed by holding the holding member 2 with one hand, holding the insulated wire 33a that is about to hang down, and the staple 26. There is utility that it can be held while maintaining an appropriate positional relationship.

In addition, in the present invention, the two nail members 27 and 27 of the staple 26 are clamped on the opposing surfaces 8 and 9 of the two clamping members 2 and 3 so that it can be understood from FIG. When the two nail members 27 and 27 are driven, the nail member holding portion 9 provided on the opposing surfaces 8 and 9 by the “thick insulating covering portion 29 surrounding the upper position of the nail member 27” as the driving proceeds. In the case of moving to the nail member sandwiching portions 13 and 14, the two sandwiching members 2 and 3 are in a direction in which the nail member sandwiching portion 9 and the nail member sandwiching portions 13 and 14 to be opposed are always close to each other. Therefore, there is a feature that it is possible to push and spread between the nail member clamping part 9 and the nail member clamping parts 13 and 14 and to descend.
This has the effect of enabling complete driving of the staple 26 without damaging the “thick insulation covering portion 29 surrounding the upper position of the nail member 27”.

  Furthermore, in the present invention, when the blocking member 12 serving as the overshoot preventing member is provided between the first nail member clamping portion 13 and the second nail member clamping portion 14, FIG. As can be understood from the above, even if the head 28 of the staple 26 is driven, it can be received by the blocking member 12, and there is no fear of damaging the insulating coating portion 35 of the insulated wire 33 due to excessive driving, and the effect of being able to work with peace of mind is achieved. is there.

  Further, when the blocking member 12 is provided as a hitting prevention member between the first nail member clamping portion 13 and the second nail member clamping portion 14, the blocking is performed when the head 28 of the staple 26 is driven. Although the member 12 is located below the head 28 of the staple 26, the two clamping members 2 and 3 can be moved away from each other so that they can be understood from FIG. In this state, the blocking member 12 is pulled out from the lower side of the head 28 of the staple 26, and there is an effect that the two clamping members 2 and 3 can be easily separated upward.

Embodiments of the present invention will be described below with reference to the drawings. The drawings are for explaining the relationship between the staple clamping device S including the first clamping member 2, the second clamping member 3, and the biasing means 16, the staple 26, and the insulated wire 33. is there.
The main body 1 of the staple clamping tool S includes a first clamping member 2 and a second clamping member 3 that are arranged freely at a distance from each other. As shown in FIGS. 1 to 5, these members 2 and 3 are molded using an arbitrary hard material such as a synthetic resin material or a metal material.

In addition, although the thing of illustration shows that the periphery is formed in square shape in planar shape (FIG. 1), what is necessary is just to make arbitrary shapes, such as an ellipse. Further, if the surface 2a and the side surface 2c are subjected to anti-slip processing such as unevenness, the operator is pleased.
Furthermore, if one or both of the above-described members 2 and 3 are formed of a transparent material, the operator can see the insulated wire 33 inside from above in the state of FIG. This is convenient for grasping the positional relationship between the staple 26 and the insulated wire 33.
The size of each of the holding members 2 and 3 may be a size that is easy for an operator to grip. For example, in the state of FIG. 1, the planar shape of the clamping member 2 may be set to 40 × 50 mm and a thickness of about 8 mm.

  In the first and second opposing surfaces 8 and 9 between the two clamping members 2 and 3, the two nail members 27 and 27 of the staple 26 are attached as shown in the state in which both are brought close to each other. The two opposing surfaces 8 and 9 are parallel to each other so that they can be clamped from both sides while being attached to both opposing surfaces 8 and 9 (see FIG. 8B). Further, in the illustrated example, in order to further enhance the clamping function, first, second, and third nail member clamping portions 13, 14, and 9a, which will be described later, are provided on the opposing surfaces 8 and 9, respectively. .

As can be understood from FIGS. 2 to 5, the insulated wires 33 (insulated wires having different sizes) can be accommodated on the back surfaces of the two clamping members 2 and 3. It is like that. In that case, in order to be able to be accommodated in the state across the two clamping members 2 and 3, the recessed groove-like wire receiving grooves 4 and 5 each opened at both ends (left and right sides 4e and 5e in FIG. 3) are respectively provided. It is provided so that it may become long toward the direction (perpendicular to the guide rod 18) that is substantially perpendicular to the facing surfaces 8,9.
As an insulated wire, for example, an insulated wire called a cord wire, an IV wire, a VVF cable, etc., usually along the surface (insulated wire fastening surface) of a construction material (beam, column, wall, etc. of a house). The arranged electric wire can be targeted.

The side groove walls 4c and 5c on one side of the two electric wire receiving grooves 4 and 5 function as electric wire attachment walls 4c and 5c to which electric wires can be attached, respectively.
That is, when the insulated wire 33 is wired on a vertical surface by making it possible to attach the wire to the wire attachment walls 4c and 5c (see FIG. 11), the insulated wire 33a that is about to hang down is sandwiched between the holding members. The insulated wire 33 can be stopped at a predetermined position by being received by the wire attachment walls 4c and 5c of the wire receiving grooves 4 and 5 on the back surfaces of 2 and 3.
In addition, in this case, since the second nail member clamping portion 14 serving as a reference point is provided near the side of the electric wire attachment walls 4c and 5c, the staple 26 is immediately provided in the above state. When the second nail member clamping portion 14 is used as a reference point and driven so that it can be understood from FIG. 7, the staple 26 can conveniently obtain a preferable positional relationship with the insulated wire 33 as can be understood from FIGS. There is sex.

Thus, in the first and second nail member clamping portions 13 and 14 provided on the opposing surface 8 of one of the two clamping members 2 and 3, the electric wire attachment wall 4c The first nail member clamping portion 13 is provided in a state where the facing surface 8 is recessed on the side of the wire receiving groove on one side, and the other side of the position of the wire attachment wall 4c. 2 is provided with a second nail member clamping portion 14 which is formed in a shape of a narrow concave groove and serves as a positioning reference point for the staple 26.
On the other hand, the concave portion 11 of the first nail member sandwiching portion 13 corresponds to the size of the staple 26 and the position of the nail member 27 of the staple 26 arranged with the second nail member sandwiching portion 14 as a reference point. The width of the wire receiving groove is increased so that it can be freely determined.

The second nail member clamping portion 14 is a concave groove 10 that opens the end portions 10a and 10b on the front and back surfaces, and the cross-sectional shape of the concave groove 10 is large or small in the diameter of the nail members 27 and 27 of the staple 26. Even if there is a change, it can be accepted correspondingly, and it is narrowed toward the depth.
The cross-sectional shape of the concave groove 10 corresponds to the diameter of the nail member 27 of the staple 26, and corresponds to that. The shape of the bottom is illustrated in FIGS. 13 (A), (B), and (C). Thus, it may be V-shaped, may be stepped, or may be arcuate. In short, the closer to the bottom, the narrower it is. Further, the depth dimension 10e of the bottomed concave groove 10 is a depth corresponding to the diameter dimension in which the diameter of the nail member 27 in the large and small staples 26 is thin (substantially the same as the diameter dimension or shallower than the diameter dimension). Even if the diameter of the nail member 27 is small, it is preferable that the nail member 27 does not move greatly in the lateral direction within the groove 10.

Further, the two clamping members 2 and 3 are urged in a direction in which the opposed surfaces 8 and 9 opposed to each other are always close to each other (arrow 22 direction).
Any known means may be used as the biasing means. For example, the means shown in FIGS. 1, 3, 4, and 5 may be used. 1, 3, 4, and 5, 17 and 17 are through holes provided in a direction perpendicular to the second facing surface 9 with respect to the second holding member 3, and 18 and 18 are formed of a hard material. The inserted guide rod is inserted into the through holes 17 and 17 so as to freely advance and retract. One free end 18 a of the guide rod is fixed by being inserted into the blind hole 7 of the first clamping member 2. The other free end protrudes as shown, and a fastener 20 is attached. Between the end face 3d of the second clamping member 3 and the fastener 20, an elastic member 10 (winding spring) as an urging means is interposed in a compressible state.
The urging force of the urging means may be a weak force that does not cause the staple 26 to fall out between the first clamping member 2 and the second clamping member 3 in the state shown in FIG.
As is well known, the fastener 20 includes a washer 20a and a C-shaped ring 20b.

26 is referred to as a staple and is used when the insulated wire 33 is attached to the wall surface 40. In many cases, 27 and 27 are nail members formed of an iron material, which are formed in a tapered state as shown in FIG. 7, and the surface is unichrome plated. Wire diameters of 1.6mm to 2.0mm are often on the market. Sometimes it is 1.2mm, but it is too small to be adopted.
Reference numeral 28 denotes a connecting member that connects and integrates the heads of the two nail members 27, 27, and the head is exposed to be hit with a hammer.
29 is an insulation coating (for example, polyvinyl chloride as a synthetic resin material) surrounding the upper position of the nail members 27, 27, and has a gradient to increase the thickness upward (toward the connecting member 28). is there. Reference numeral 30 denotes an insulating coating of the same material surrounding the periphery of the connecting member, which is integrated with a nail member or the like.

  33 is generally called an insulated electric wire, and represents an electric wire arranged along the surface of a construction material such as a cord wire, an IV electric wire, or a VVF cable. 34 is a conductor (one or more) surrounded by an insulator, 35 is an insulator, and 40 is a surface of a construction material (for example, a beam, a column, or a wall of a house). Show.

  A use aspect is demonstrated about the thing of the said structure. When the surface 40 of the construction material to be wired is determined at the site, the wiring is prepared so that it can be understood from FIGS. First, the first opposing surface 8 and the second opposing surface 9 between the first clamping member 2 and the second clamping member 3 are relatively opened. As a means, the first clamping member 2 and the second clamping member 3 may be held in their hands and opened in the direction of the arrow 23, or the first opposing surface 8 and the second opposing surface 9 may be opened. The nail members 27 and 27 of the staple 26 may be inserted between them to open against the urging force of the elastic material 19.

Next, as can be understood from the drawing, one of the nail members 27 is positioned in the second nail member clamping portion 14 (bottom narrow concave groove 10) serving as a reference point for the stapling position. The other of the nail members 27 is positioned in the first nail member clamping portion 13 that is formed wide. In this case, regardless of whether the staple 26 is small or large, the concave portion 11 is formed with a wide width, and thus can cope with various types. After setting the staple 26 to the main body 1 of the staple holding tool in this way (after the state shown in FIG. 6B), the insulation disposed on the surface 40 of the construction material as shown in FIG. 6C. Cover the wire 33. In that case, it is desirable that there is no gap between the side surface of the insulated wire 33 and the reference side surface side groove wall (wire attachment wall 4c) (see FIG. 7B).
In addition, as a procedure of covering the main body 1 of the staple holding tool with respect to the insulated wire 33, after covering the main body 1 of the staple holding tool with respect to the insulated wire 33, the staple 26 is connected to the first facing surface 8 and the second surface. It may be inserted between the opposite surface 9.

In this state, that is, the state of FIG. 6C and FIG. 7B, the hammer 36 is hit with the head of the staple 26 and driven. In this case, the left member 3 (second holding member 3) or the right member 2 (first holding member 2) of the main body 1 of the staple holding device is gripped, but these sizes are substantially the same. If you make it big, you can hold either the left or right.
Further, in the case of the above-described driving, if there is no blocking member 12, the driving is performed to the position shown in FIG. In this case, care is taken so that the insulation coating 35 of the insulated wire 33 is not damaged by being driven too much.

However, when the blocking member 12 is present, the staple 26 stops at the position indicated by the solid line in FIGS. 7C and 8A. That is, there is an effect that does not reach the point where the insulation coating 35 of the insulated wire 33 is compressed and damaged.
In this state, since the nail member 27 of the staple 26 is driven in from the surface 40 of the construction material and is in an immobile state, the staple clamp S is no longer necessary.
Therefore, it is removed. The removal means may be changed from the state of FIGS. 7C, 8A and 8B to the state of FIG. That is, when the first clamping member 2 and the second clamping member 3 are relatively moved in the direction of the arrow 23, the first clamping member 2 and the second clamping member 3 can be lifted and removed. it can. Thereafter, the insulated wire 33 may be fixed with the staple 26 as shown in FIG.

   Next, a usage example in the case of wiring on the wall surface will be described with reference to FIG. Reference numeral 40a denotes a wall surface formed in a substantially vertical plane, and reference numeral 40b denotes a cross member constituting a part thereof. An insulated wire 33 is wired on the surface 40 as shown. In this case, the insulated wire 33 is fixed by the staple 26 sequentially from the right side. Therefore, the left free end 33a of the insulated wire 33 hangs down due to its own weight.

However, in the wiring work, in this case, the staple 26 is first supported at an appropriate position only by supporting the first clamping member 2 (or the second clamping member 3) with one hand. Secondly, there is an advantage that the two support can be performed simultaneously, that is, the insulated wire 33 is also supported at an appropriate position.
That is, the stapler 26 can be sandwiched as shown in the state in which the staple member 26 straddles the insulated wire 33 between the two sandwiching members 2 and the sandwiching member 3, and the insulated wire 33 can be understood from FIG. Since it can be supported by the electric wire attachment wall 4c and the electric wire attachment wall 5c close to the second nail member clamping portion 14, the first clamping member 2 (or the second clamping member 3) is supported with one hand. Immediately, the hammer 36 can be gripped with the other hand, and the staple 26 can be driven.

In the description of the drawings, in the description of the subsequent drawings (FIGS. 11 to 14) with respect to the previous drawings, the functions, properties, means, or features of the components, components, etc., using the same reference numerals as in the previous drawings. Etc. are the same as the explanations of the same reference numerals in the previous drawings, except for matters relating to the explanation of the structure and combination of new members added in the explanation. Accordingly, in the description of the subsequent drawings with respect to the previous drawings, a part of the overlapping description is omitted.

Next, FIG. 12 is a drawing for explaining an example in which the wire diameter of the nail member 27 is different from that of the second nail member clamping portion 14. FIG. (B) shows an example in which the wire diameter of the nail member 27 is substantially the same as the depth dimension 10 e of the nail member clamping portion 14.
In FIG. 2A, the wire diameter of the nail member 27 is slightly larger than the cross-sectional shape of the nail member clamping portion 14, and a slight gap remains at the bottom of the groove. An example in which a gap is generated between the opposing surfaces 9 is shown.
In FIG. 5C, the diameter of the nail member 27 is larger than that of the cross-sectional shape of the nail member clamping portion 14 and is supported by the opening edge 10d of the groove, and a large gap remains at the bottom of the groove. An example in which a large gap is generated between the surface 8 and the second facing surface 9 is shown.

Next, FIG. 13 shows an example in which the cross-sectional shape of the groove (bottom narrow groove 10) of the second nail member clamping portion 14 is different, and is illustrated in FIGS. 13 (A), (B), and (C). Thus, it may be V-shaped, may be stepped, or may be arcuate. If at least three of the peripheral surfaces of the nail member 27 are in contact with the side surfaces of the first clamping member 2 and the second clamping member 3, the staple 26 can be stably supported and can be driven. .
13B and 13C, the second nail member clamping portion 14 is also applied to the second facing surface 9 serving as a nail member clamping portion of the second clamping member 3. The bottom narrow groove 10g having the same idea as the bottom thin groove 10 is provided as the third nail member clamping portion so as to face the position.

The concave groove 10g is a concave groove whose ends (upper and lower) are opened on the front and back surfaces, and the cross-sectional shape of the concave groove can cope with a change in the diameter of the nail member 27 of the staple 26 as shown in the figure. The bottom is made thin so that it can be accepted. In addition, the depth dimension 10h of the concave groove 10g as the third nail member clamping portion is equal to the depth dimension 10e of the concave groove of the second nail member clamping portion 14 and the third nail member clamping portion. The sum of the groove 10g and the depth 10h is a dimension corresponding to the diameter of the nail member 27 in the small and large staples 26 being thin.
Therefore, the depth dimension 10e of the groove 10 provided on the first facing surface 8 in FIGS. 13B and 13C is smaller than that in the case of FIG.

  Furthermore, in the above description, the example in which the first nail member clamping portion 13, the second nail member clamping portion 14 and the like are arranged with respect to the first clamping member 2 has been described. In contrast to the second clamping member 3, the second nail member clamping part 14, the guide rod 18, etc. may be arranged for any of them.

FIG. 14 shows an example in which the elastic member 19 (spring) of FIG. 5 is housed inside with a part of the through-hole 17 of the second clamping member 3 having a large diameter, and the elastic member 19 is surrounded.
