<First embodiment>
First, the decorative plate according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 3.
The decorative plate of the first embodiment is composed of a pair of halves, is assembled to each other by an assembling portion to form an annular shape, and is an elongated body drawn out from a wall hole provided in a wall surface such as a ceiling wall or a partition wall. It surrounds and surrounds the wall hole. Here, in the present embodiment, as the elongated body, a resin tube made of a hollow cylindrical body having a smooth outer surface made of a synthetic resin such as vinyl chloride resin, into which a wiring material such as a cable is inserted, is exemplified.

In FIG. 1, a decorative plate 1A is formed in an annular shape by assembling the half-divided surfaces 12, 12 of a pair of halves 11, 11 into contact with each other, and is formed in an annular shape. Is formed to have a flat disk shape. The through hole 13 through which the resin tube 52 penetrates in the decorative plate 1A is formed in a concentric shape.

The pair of halves 11 and 11 are formed in the same shape, that is, they are formed in the same size and the same shape with a synthetic resin material or the like. The half body 11 is formed in a semicircular plate shape in which a semicircular through space 14 through which the resin pipe 52 penetrates is provided, and the semicircular substrate 15 has a constant peripheral edge except for the through space 14. An outer frame wall 16 having a height is erected. Here, the through space 14 becomes the through hole 13 by assembling the pair of halves 11, 11 and also becomes the annular inner portion 17.

In the vicinity of the half-split surface 12 on the peripheral edge of the through space 14, an elastic piece 18 is provided so as to project toward the half-split surface 12 of the other half body 11 facing each other. The elastic piece 18 bends and deforms along the plane of the substrate 15 about a base end 19 fixed at a position spaced inward from the half-split surface 12 and elastically tilts. It projects in a direction orthogonal to the half-split surface 12 of the half body 11. An engaging portion 20 having a bulging portion 21 that bulges like a hook is formed on the protruding tip of the elastic piece 18, and the engaging portion 20 is provided on the other half body 11 so as to protrude from the half-split surface 12. It is adapted to engage with the engaged portion 23. Further, a pressed portion 22 that bulges toward the through space 14 is formed substantially in the middle of the base end 19 of the elastic piece 18 and the engaging portion 20. The pressed portion 22 is formed in a step portion, and the surface on the side of the through space 14 contacts the outer surface of the resin pipe 52.

An insertion space 24 into which the engaging portion 20 of the elastic piece 18 of the other half body 11 can be inserted is formed at a location on the opposite side of the elastic piece 18 that sandwiches the through space 14 in the half-split surface 12. An engaged portion 23 with which the hook-shaped bulge portion 21 of the engaging portion 20 of the elastic piece 18 engages is formed in a portion of the outer surface wall 16 of the split surface 12 adjacent to the insertion space 24. That is, the pair of halves 11, 11 are assembled with each other by engaging the engaging portion 20 and the engaged portion 23 of the elastic piece 18 with each other to form the decorative plate 1A. The engaging portion 20 and the engaged portion 23 of these elastic pieces 18 constitute an assembling portion, and the assembling portion constituted by these also constitutes the main assembling portion 25. The elastic piece 18 is bent and deformed toward the annular inner side 17 with the base end 19 as an axis, whereby the engagement of the engagement portion 20 with the engagement portion 23 is released, and the assembling of the both halves 11 is released.

Next, a method of attaching the decorative plate 1A thus formed to the resin pipe 52 drawn out from the wall hole 62 of the wall surface 61 will be described with reference to FIGS. 2 and 3.
First, as shown in FIGS. 2(a) and 3(a), the pair of halves 11 and 11 are brought close to the resin pipe 52 drawn from the wall hole 62 so as to sandwich it from both sides. At this time, the elastic piece 18 projects in a direction orthogonal to the half-split surface 12 of the other half body 11, and a part of the pressed portion 22 projects into the through space 14. In this state, if the two halves 11 are brought close to each other, as shown in FIG. 2B, the elastic piece 18 is pressed while the engaging portion 20 is inserted into the insertion space 24 of the half-split surface 12. The portion 22 is pressed against the outer surface of the resin pipe 52, and the engaging portion 20 is flexibly deformed and tilted toward the engaged portion 23 side of the other half body 11 about the base end 19 as an axis, and the engaging portion 20 of the hook-shaped swelling portion 21. The slope contacts the corner of the engaged portion 23 on the half-splitting surface 12 side.

Then, when the elastic piece 18 is further pushed into the insertion space 24, the top of the bulging portion 21 of the engaging portion 20 is pushed to the end surface of the insertion space 24, that is, the covered portion of the elastic piece 18, as shown in FIG. The side end surface 23a of the engaging portion 23 is in a riding surface contact state. At this time, the engaging portion 20 is pressed by the side end surface 23a of the engaged portion 23 and part of the engaging portion 20 tries to protrude into the annular inside 17, while the pressed portion 22 is pressed from the side opposite to the engaged portion 23 from the resin pipe. It is pressed by the outer surface of 52. Therefore, the elastic piece 18 is further flexibly deformed so as to be slightly convex and curved on the side opposite to the annular inner side 17.

Then, when the elastic piece 18 is further pushed in, the top of the bulging portion 21 of the engaging portion 20 rides over the side end surface 23a of the engaged portion 23 of the other half body 11, while the pressed portion 22 is made of resin. Since the outer surface of the pipe 52 is pressed toward the engaged portion 23 side, the bending deformation of the elastic piece 18 in the curved state is reduced and becomes gentle, while the engaging portion 20 moves to the back surface side of the engaged portion 23, that is, the inner surface side. It falls and becomes the state of FIG. 2(d). FIG. 2D shows a state in which the engagement portion 20 of the elastic piece 18 and the engagement portion 23 of the other half body 11 are completed. FIG. 3B shows a state in which the decorative plate 1A is attached to the resin pipe 52 and the wall hole 62 is covered and hidden.

In this series of assembling, the elastic piece 18 is flexibly deformed and tilted about the base end 19, and the engaging portion 20 is shown in FIG. ), which is shown in ), moves to a position where the other half 11 is engaged with the engaged portion 23. If this is shown in FIG. 2, the engaging portion 20 moves vertically between the two positions. The engaging portion 20 of the elastic piece 18 is shown in FIG. 2(a) before the pressed portion 22 of the elastic piece 18 comes into contact with the outer surface of the resin pipe 52 before the pair of half bodies 11, 11 is assembled. It is located at the position shown, that is, in the middle between the position shown in FIG. 2(c) and the position shown in FIG. 2(d).

Then, once engaged as shown in FIG. 2(d), the pressed portion 22 of the elastic piece 18 is in contact with the outer surface of the resin pipe 52, so that the elastic piece 18 is bent into the annular inside 17. Deformation is regulated, and the engagement between the engagement portion 20 and the engaged portion 23 is stably maintained without loosening.

Next, the operation of the decorative plate 1A of the first embodiment will be described.
In the decorative plate 1A, the pressed portion 22 of the elastic piece 18 contacts the outer surface of the resin tube 52 in a state where the resin tube 52 is arranged in the annular inner portion 17, so that the engaging portion 20 of the elastic piece 18 is formed in the annular inner portion 17. Since the movement to the side is restricted, once the pair of half bodies 11, 11 are assembled and the decorative plate 1A is attached to the resin pipe 52, the engaging portion 20 of the elastic piece 18 is covered by the other half body 11. The engagement with the engagement portion 23 is prevented from being disengaged. That is, conventionally, the pair of halves are easily disengaged from each other because the pair of halves are apt to come off due to the radial reaction force generated by the resin pipe 52 disposed in the annular inner portion 17 and being pushed outward. The plate 1A strengthens the engagement between the engagement portion 20 of the elastic piece 18 and the engagement portion 23 of the other half body 11 by reversely utilizing the reaction force from the outer surface of the resin pipe 52. Thus, the presence of the resin pipe 52 in the ring-shaped inside 17 of the pair of half bodies 11, 11 causes the engaging portion 20 and the engaged portion 23 of the elastic piece 18 to engage with each other very firmly, and the pair of half bodies. It is possible to surely prevent a gap from being formed between 11 and 11 and the disassembly of both halves 11.

Further, in the decorative plate 1A, by simply sandwiching the resin pipe 52 from both sides with the pair of half bodies 11, 11, the pressed portion 22 of the elastic piece 18 abuts the outer surface of the resin pipe 52 and the engaging portion 20 engages. Since the pair of halves 11 and 11 are engaged with the portion 23 and the half body 11 is assembled, the decorative plate 1A can be attached to the resin pipe 52 with good workability and with a simple structure at a low cost.

Further, since the pressed portion 22 of the elastic piece 18 is provided closer to the base end 19 side than the hook portion 20, the lever portion centering on the base end portion 28 causes the hook portion 20 to press the pressed portion 22 of the resin pipe. The force is increased to be larger than the pressing force that abuts against 52 and is pressed against the engaged portion 23 side of the other half body 11. Therefore, the engaging portion 20 of the elastic piece 18 is engaged more firmly with the engaged portion 23 of the other half body 11.

In the decorative plate 1A, the elastic pieces 18 of the pair of halves 11 and 11 are provided on both sides of the resin pipe 52 arranged in the ring-shaped inner portion 17, so that the decorative plate 1A is stable and stable. Attached to.

<Second embodiment>
Next, the decorative plate 1B and the annular portion forming member of the second embodiment of the present invention will be described based on FIGS. 4 to 8. Here, the decorative plate 1B of the second embodiment is attached around the elongated body 51 drawn out from the wall hole 62, whereas the annular portion forming member is not limited to the decorative plate 1B. Widely refers to a member forming the annular portion 32 through which the elongated body 51 penetrates. However, since the annular portion forming member is configured substantially the same as the decorative plate 1B, the decorative plate 1B will be described here as a representative. In addition, the decorative plate 1B of the second embodiment is different from the decorative plate 1A of the first embodiment in that the pair of half bodies 11, 11 are mutually arranged in a state in which the elongated body 51 is not arranged in the annular inside 17, which will be described later. The difference is that a temporary assembly portion 26 that can be temporarily assembled and a positioning portion 33 for the elongated body 51 are further provided. Therefore, here, the difference from the decorative plate 1A of the first embodiment will be mainly described.

4 to 6, the decorative plate 1B is provided with the elastic piece 18 and the engaged portion 23 of the decorative plate 1A of the first embodiment, and each half body 11 is engaged with the engagement protrusion 27. The temporary assembly portion 26 including the hole 31 and the positioning portion 33 including the locking claw 34 are provided. The pair of halves 11 and 11 are formed in the same manner, that is, they are made of a synthetic resin material and have the same size, the same shape, and the same structure. When the pair of halves 11 and 11 are assembled, an annular portion 32 through which the resin pipe 52 penetrates is formed inside, that is, in the center.

First, the engagement protrusion 27 that constitutes the temporary assembly portion 26 is integrally provided on the outer peripheral side portion of the half-divided surface 12 that is a separate portion separated from the engaging portion 20 of the elastic piece 18. As shown in FIGS. 4(a), 7(a), etc., the engagement protrusion 27 is composed of a base end portion 28 joined to the half-split surface 12 and an engagement portion 29 on the tip end side. The portion 29 swells gently to the side, and the inclined surfaces of the bulging portion 30 on the tip end side and the base end 19 side are gently inclined. That is, the bulging portion 21 of the engaging portion 20 of the elastic piece 18 constituting the main assembly portion 25 bulges laterally in a hook shape, whereas the bulging portion 30 of the engaging projection 27 is gentle. It bulges out. A pair of anti-symmetrical protrusions 27 are arranged side by side at a slight interval, projecting in a direction orthogonal to the half-split surface 12 of the facing half body 11, and the base end portion 28 is located on the axis side. It can be bent and deformed in one direction.

On the side of the half-splitting surface 12 opposite to the engaging projection 27 sandwiching the through space 14, a square hole into which the engaging projection 27 can be inserted at a position facing the engaging projection 27 of the other half 11 is formed. The engagement hole 31 is formed, and the bulging portion 30 of the engagement protrusion 27 can be engaged with the engagement hole 31. The peripheral edge of the engaging hole 31 on the half-splitting surface 12 side is chamfered at the corners so that the engaging projection 27 can be easily inserted. That is, the pair of halves 11 and 11 are assembled by engaging the engaging portion 29 of the engaging protrusion 27 and the engaging hole 31 with each other. The temporary assembling portion 26 constituted by the engaging protrusions 27 and the engaging holes 31 temporarily puts the halves 11 into an assembled state, and the bulging portion 30 of the engaging portion 29 is gently inclined. Since the bulging portion is engaged with the engaging hole 31 of the other half body 11 by the frictional force with the peripheral corner portion, if the pair of half bodies 11, 11 are pulled outward in the left and right directions, The engagement between the fitting protrusion 27 and the engagement hole 31 can be easily released. However, even though the engagement can be easily released, it has an engagement force that does not disengage at least during handling during temporary assembly or during carrying.

Next, the positioning portion 33 is attached to the intermediate portion of each half body 11, and is formed by a square frame-shaped locking claw 34 made of a thin metal piece as shown in FIG. The claw portion 36 is bent and the tip portion thereof projects into the annular inner portion 17. The base portion 35 of the locking claw 34 is press-fitted and mounted in the mounting grooves 38, 38 of the pair of mounting block bodies 37, 37 provided upright on the substrate 15 of the half body 11. As shown in FIGS. 4(a) and 6(b), the pawl portion 36 of the locking pawl 34 is bent slightly obliquely downward from the base portion 35, and has a side 39 on the annular inner side 17 side. Is cut out in a V shape. Then, the notched side 39 of the claw portion 36 slightly protrudes into the annular inner portion 17 and bites into the outer surface of the resin pipe 52 to be locked.

Next, a situation in which the decorative plate 1B thus formed is temporarily assembled will be described with reference to FIG. In the temporary assembly, the pair of halves 11 and 11 are assembled in a state where the resin pipe 52 is not arranged in the ring-shaped inside 17.

First, as shown in FIG. 7A, the pair of halves 11 and 11 are brought close to each other with the resin pipe 52 drawn out from the wall hole 62 being sandwiched from both sides. At this time, the elastic piece 18 projects in a direction orthogonal to the half-split surface 12 of the other half body 11, and a part of the pressed portion 22 projects into the through space 14. Further, the engagement protrusions 27 project in a direction orthogonal to the half-split surface 12 of the other half body 11. If both halves 11 are brought close to each other in this state, the elastic piece 18 approaches the engaged portion 23 of the other half 11 in the same posture as in FIG. 7(a), as shown in FIG. 7(b). Then, the engaging portion 29 of the engaging protrusion 27 is inserted into the engaging hole 31 of the other half body 11.

Therefore, when the two halves 11 are further brought closer to each other, the top of the bulging portion 21 of the engaging portion 20 of the elastic piece 18 becomes the end surface of the insertion space 24, that is, the engaged portion 23, as shown in FIG. 7C. The riding surface comes into contact with the side end surface 23a, and the elastic piece 18 slightly tilts about the base end 19 toward the inner ring 17 side. The pair of engaging projections 27, 27 are inserted into the engaging holes 31 while the engaging portions 29 are bent in the direction in which the engaging portions 29 approach each other around the base end portion 28 as an axis.

After that, when the two halves 11 are further brought closer to each other and the half-divided surfaces 12 of the both halves 11 come into contact with each other, as shown in FIG. Of the other half 11 rides over the side end surface 23a of the engaged portion 23 of the other half body 11, and the engaging portion 20 falls to the back side, that is, the inner surface side of the engaged portion 23, and has the same protruding posture as in FIG. 7A. Further, in the engagement protrusion 27, the bulge portion 30 of the engagement portion 29 penetrates the engagement hole 31 and engages with the engagement hole 31. Here, in the engaging projection 27, the bulging portion 30 of the engaging portion 29 swells with a gentle slope, and the engaging hole 31 of the other half body 11 is swelled by a frictional force with a peripheral corner portion thereof. Engage. This completes the temporary assembly of the pair of halves 11, 11. 4(b), FIG. 5 and FIG. 6 show the state after the temporary assembly is completed.

After that, in the decorative plate 1B temporarily assembled in a state where the resin tube 52 is not arranged in the ring-shaped inside 17, the bulging portion 30 of the engaging projection 27 bulges gently to the side, and Since the engaging portion 20 is not engaged with the engaged portion 23, the engagement between the engaging protrusion 27 and the engaging hole 31 is easily released by pulling the two halves 11 in the direction in which they are separated from each other, and the temporary assembly is performed. Is released and the two halves 11 can be separated.

Next, attachment of the decorative plate 1B of the second embodiment to the resin pipe 52 will be described.
Attaching the decorative plate 1B to the resin pipe 52 drawn out from the wall hole 62 is often an operation at high places. In such a case, it is easier to work by temporarily assembling the pair of halves 11, 11. Therefore, first, the pair of halves 11, 11 is temporarily assembled by the temporary assembly portion 26. Next, when the temporarily assembled decorative plate 1B is brought to a mounting site such as a high place, the temporarily assembled pair of halves 11 and 11 are pulled and separated to release the temporary assembly. Thereafter, similar to the first embodiment, the pair of half bodies 11, 11 are brought close to each other with the resin pipe 52 sandwiched from both sides, and the main assembly including the engaging portion 20 and the engaged portion 23 of the elastic piece 18 is formed. The pair of halves 11, 11 are assembled by the attachment part 25, and the decorative plate 1B is attached to the resin tube 52.

After the decorative plate 1B is attached to the resin pipe 52, in the main assembly portion 25, the pressed portion 22 of the elastic piece 18 is in contact with the outer surface of the resin tube 52. The flexural deformation is restricted, the engaging portion 20 of the elastic piece 18 and the engaged portion 23 are engaged very firmly, and the engagement is stably maintained. Further, in addition to the engagement between the engaging portion 20 and the engaged portion 23 of the elastic piece 18 by this assembling, the engaging protrusion 27 and the engaging hole 31 are engaged with each other. However, substantially, the decorative plate 1B is assembled by the main assembly portion 25.

Next, the operation of the positioning portion 33 will be described.
Since the positioning portion 33 is formed by the locking claw 34 including the base portion 35 and the claw portion 36 that is bent from the base portion 35 and protrudes into the annular inside 17, when the decorative plate 1B is assembled to the resin pipe 52, The tip portion of the claw portion 36 bites into the outer surface of the resin pipe 52 and is locked. Further, since the claw portion 36 is bent slightly obliquely downward from the base portion 35, it can be moved to one side along the longitudinal direction of the resin pipe 52 while being locked to the outer surface of the resin pipe 52. However, movement is restricted on the other side.

That is, as shown in FIG. 8, the tip of the claw portion 36 of the locking claw 34 slightly bites into the outer surface of the resin pipe 52, and the claw portion 36 is attached in a state of being bent from the base portion 35 to the left in FIG. To be Therefore, the decorative plate 1B can move to the right as indicated by the chain double-dashed line in FIG. 8 with relatively little resistance, but when it is attempted to move to the left as indicated by the solid line in FIG. Since a reaction force is generated due to the bending of the blade and a large resistance is applied, it becomes impossible or difficult to move. The decorative plate 1B is movable to the right in FIG. 8 with respect to the resin pipe 52, but the wall surface 61 prevents the movement. Therefore, when the decorative plate 1B is attached to the resin pipe 52 and a gap is formed between the decorative plate 1B and the wall surface 61, the decorative plate 1B can be moved to the wall surface 61 side and brought into close contact with the outer frame wall 16. As a result, the decorative plate 1B can be fixed to a fixed position of the resin pipe 52 while being in close contact with the wall surface 61. As a result, for example, when the decorative plate 1B is attached to the wall hole 62 of the wall surface 61 of the ceiling, it is possible to prevent the decorative plate 1B from dropping along the resin pipe 52 by its own weight.

Here, the substrate 15 of each half body 11 is provided with a break groove 40 formed of a linear thin groove in a portion forming a chord of a circle parallel to the half-split surface 12. Is thin and can be broken off by hand. The break-off groove 40 is used when a wall hole 62 through which the resin pipe 52 penetrates is provided near the wall and the space for mounting the decorative plate 1B is small, so that a part of the break-off groove 40 cannot interfere with the wall surface 61 for mounting. The decorative plate 1B can be attached as shown in FIG. 9 by breaking off 15 at the breaking groove 40.

Next, the operation of the decorative plate 1B of the second embodiment will be described.
In the decorative plate 1B of the second embodiment, since each half body 11 includes the elastic piece 18 and the engaged portion 23, the decorative plate 1B operates similarly to the decorative plate 1B of the first embodiment. In addition, in the decorative plate 1B of the second embodiment, the pair of halves 11 and 11 has the temporary assembly portion 26 including the engagement protrusion 27 and the engagement hole 31, so that the installation site is at a high place. It can be handled and carried in the temporarily assembled state until the main assembly. For this reason, it is easier to handle than carrying two separated half bodies 11, and workability is improved. Further, the half body 11 is less likely to be dropped while being carried, and the half body 11 is less likely to be lost during transportation, handling, or storage.

Since the decorative plate 1B of the second embodiment has the positioning portion 33 that determines its position with respect to the resin pipe 52, the decorative plate 1B is prevented from separating from the wall hole 62 and the wall hole 62 is exposed. This can be reliably prevented, and the appearance around the wall hole 62 can be kept good.

By the way, in the decorative plate of each of the above-mentioned embodiments, the pair of half bodies 11, 11 are the same as each other, but may be different from each other. For example, in the decorative plate 1B, the elastic piece 18, the hooked portion 23, the engaging protrusion 27, and the engaging hole 31 are all provided in both half bodies 11, but as shown in FIG. Two elastic pieces 18 and two pairs of engaging protrusions 27 are provided on the half body 11, and the other half body 11 is a engaged portion 23 that engages with the engaging portion 20 of the elastic piece 18, and an engaging protrusion 27. Two engaging holes 31 that engage with each other may be provided.

Further, in the decorative plate of each of the above embodiments, the pair of halves 11 and 11 are separated from each other. However, as shown in FIG. It can also be of a connected structure. In this case, as shown in FIG. 11( a ), the elastic piece 18 and the engaged portion 23 that engages with the assembly portion 25 may be provided for each half body 11 one by one. As shown in FIG. 11(b), the elastic piece 18 may be provided only on one of the half bodies 11, and the engaged portion 23 may be provided only on the other half body 11.

In the case of this hinge 41 structure, since the pair of halves 11 and 11 are connected and integrated by the hinge 41, the temporary assembly portion 26 including the engagement protrusion 27 and the engagement hole 31 that engages with this is unnecessary. However, the temporary assembling section 26 may also be provided together.

Further, in the temporary assembly portion 26 of the second embodiment, the engagement protrusion 27 has a gentle bulging portion 30, and the bulging portion 30 and the peripheral corner portion of the engaging hole 31 of the other half 11 are arranged. The engaging portion 29 is engaged with the engaging hole 31 by a frictional force with the engaging portion 29. However, the engaging portion 29 of the engaging protrusion 27 is formed in a hook shape, and the engaging portion 31 is engaged with the engaging hole 31. It does not prevent the pair of halves 11 and 11 from being disengaged and separated by strongly pulling the pair of halves 11 in the left and right outer directions.

In addition, although the positioning portion 33 of the second embodiment is formed by the locking claw 34 and locks on the outer surface of the resin pipe 52, the present invention is not limited to this, and the resin pipe 52 is simply caused by frictional force. The elastic member 18 may be locked to the outer surface thereof, or the pressed portion 22 of the elastic piece 18 may also serve as the positioning portion 33. In the latter case, in the decorative plate 1B, for example, the pressed portion 22 becomes a wedge between the side end surface 23a of the engaged portion 23 and the outer surface of the resin pipe 52, and is pressed against the outer surface of the resin pipe 52. When the elongated body 51 is a hanging bolt, it can be considered that the elongated body 51 is locked in a fixed position of the resin pipe 52 by engaging with the thread groove of the outer surface thereof.

In addition, in the second embodiment, the positioning portion 33 does not necessarily have to be provided. On the other hand, in the first embodiment, the positioning portion 33 is not provided on the decorative plate 1A, but may be provided on the decorative plate 1A.

Similarly, the breaking groove 40 for installing the decorative plate 1B near the wall in the second embodiment does not necessarily have to be provided. On the other hand, the break groove 40 may be provided in the decorative plate 1A of the first embodiment.

In addition, although the decorative plate of each of the above-described embodiments is formed in a donut shape in which the annular portion 32 is circular, the present invention is not limited to this shape, and the annular portion 32 is formed around the elongated body 51 and the wall hole 62. Depending on the situation, etc., it may be formed in a polygonal shape such as a quadrangle shape, a hexagonal shape, or an elliptical shape.

By the way, although the decorative plate is described in the first and second embodiments, the present invention can be applied to a wider annular member forming the annular portion 32 through which the elongated body 51 penetrates. is there. As the annular portion forming member, in addition to the decorative plate, a closing member such as a lid for non-cosmetic purposes and having a through hole for the elongated body 51, or a member for sandwiching the elongated body 51 from both sides and fixing it at a predetermined position For example, a lid for closing the wall hole 62 for preventing the leakage preventing caulking agent filled in the wall hole 62 through which the elongated body 51 falls from falling from the wall hole 62. Can be mentioned.

Further, in each of the above-described embodiments, as the elongated body 51, the resin pipe 52 formed of a hollow cylindrical body having an outer smooth surface made of vinyl chloride or the like is illustrated, but as the elongated body 51 to which the present invention is applied, Other examples include hollow cylinders such as corrugated pipes made of synthetic resin, metal pipes, and protective ducts, and various elongated bodies such as cables and suspension bolts.
