DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, one embodiment will be described with reference to FIGS. As shown in FIG. 1, the wall-embedded pipe cover (hereinafter, pipe cover 10) includes a first base member 20, a first decorative cover 30, a second base member 40, a second decorative cover 50, a cut surface cover 60, and a band base 70. Next, each component of the piping cover 10 will be described in detail.

[0010] <First base member 20> 1 to 3, the first base member 20 has a trough-shaped accommodating recess 21 that accommodates a pipe 101 (long body) as the piping member 100, and a pair of flange portions 27 formed on both sides in the width direction of the accommodating recess 21. The first base member 20 is formed with a rib 21b that protrudes from the flange portion 27 and forms an opening 21a.

[0011] The accommodation recess 21 has a long, flat bottom wall 22 and a pair of opposing side walls 23 that are bent and extend from both ends of the bottom wall 22 in the width direction. The outer surfaces of both side walls 23 are planar and parallel to each other. A bottom surface 22a, which is the surface of the bottom wall 22, functions as an installation surface to which the band base 70 is fixed.

[0012] On the inner surface of each side wall 23, in order from closest to the bottom wall 22, a pair of first ridges 24, a pair of second ridges 25, and a pair of third ridges 26 extend along the longitudinal direction of the bottom wall 22 and over the entire longitudinal direction. The first ridges 24, the second ridges 25, and the third ridges 26 face each other in the width direction of the accommodating recess 21.

[0013] Each flange portion 27 extends outward in the width direction of the accommodating recess 21 from the outer surface of the tip of each side wall 23. A plurality of screw holes 28 are provided at intervals in each flange portion 27. Each flange portion 27 is also provided with a groove 29 that serves as a marker for the position of a pilot hole when fastening the flange portion 27 at a location other than the screw holes 28. The first base member 20 is integrally formed from a hard resin material by extrusion molding.

[0014] <First decorative cover 30> As shown in Figures 1 and 3, the first decorative cover 30 has a flat cover body 31 that covers the opening 21a of the accommodating recess 21 and is overlapped with the flange portion 27, and a pair of protrusions 32 formed on the back surface of the cover body 31.

[0015] The cover body 31 has a rectangular shape when viewed from the front. Both widthwise end edges of the cover body 31 are formed with inclined portions that are inclined toward the rear side of the cover body 31 as they move outward in the widthwise direction, and protruding portions that protrude from the inclined portions toward the rear side of the cover body 31.

[0016] Each of the protrusions 32 extends along the longitudinal direction of the cover body 31 and over the entire longitudinal direction. The protrusions 32 are inclined so that they approach each other the further they are from the cover body 31. A locking claw 33 is formed at the tip of each of the protrusions 32. The locking claws 33 are inclined so that they move away from each other the further they are from the cover body 31. Both ends of the first decorative cover 30 in the longitudinal direction are cut surfaces 30a.

[0017] 3, the first decorative cover 30 is assembled to the first base member 20 by engaging the locking claws 33 with the third ridges 26 of the first base member 20. At this time, a gap S is formed between the cover body 31 and each flange portion 27. Even if the cover body 31 is pressed from the front surface, the rib 21b of the first base member 20 supports the back surface of the cover body 31, making it difficult for the cover body 31 to deform. The first decorative cover 30 is integrally molded from a hard resin material. The first decorative cover 30 of the present embodiment is formed by extrusion molding.

[0018] <Second base member 40> 1, the second base member 40 has an accommodating recess 41 that accommodates a joint 102 as a piping member 100, and flange portions 47 formed on both sides of the accommodating recess 41. The accommodating recess 41 has a bottom wall 42 and a side wall 43 that is bent and extends from an edge of the bottom wall 42 and has an inverted U-shape when viewed from the front.

[0019] A recess 42a is formed on the surface of the bottom wall 42 to allow the rear portion of the joint 102 to escape. A plurality of screw holes 45 are formed at intervals in the portion of the bottom wall 42 surrounding the recess 42a.

[0020] 1 and 12, a pair of engagement portions 46 protruding toward the front side are formed on the bottom wall 42. The pair of engagement portions 46 are provided side by side on the first base member 20 side with respect to a pair of screw holes 45 formed on either side of the recess 42a in the width direction.

[0021] The flange portion 47 extends from the outer surface of the tip of the side wall 23 outward in the width direction and toward the opposite side from the first base member 20. The flange portion 47 is provided with a plurality of screw holes 48 and a plurality of engagement holes 49 spaced apart from one another.

[0022] The second base member 40 has extensions 44 extending from both the bottom wall 42 and the side walls 43 towards the first base member 20 side. The second base member 40 is integrally molded from a hard resin material. In this embodiment, the second base member 40 is formed by injection molding.

[0023] <Second cosmetic cover 50> As shown in FIG. 1, the second decorative cover 50 has a flat cover body 51 that covers the opening 41a of the accommodating recess 41 and is fitted over the flange portion 47, and a plurality of engagement claws 52 formed on the back surface of the cover body 51.

[0024] The cover body 51 has a generally rectangular shape when viewed from the front. Among the four edges of the cover body 51, three edges 51b, excluding the edge 51a overlapping with the first decorative cover 30, are formed with an inclined portion that is inclined toward the back side as it approaches the outside, and a protruding portion that protrudes from the inclined portion toward the back side.

[0025] When the second decorative cover 50 is attached to the second base member 40, the protruding portion of the edge 51b is located on the outer periphery side of the flange portion 47 of the second base member 40. An insertion hole 51c is provided in the center of the cover body 51 to allow a faucet or the like to be connected to the joint 102 to pass through. The second decorative cover 50 is integrally molded from a hard resin material. The second decorative cover 50 of the present embodiment is formed by injection molding.

[0026] <Cutting surface cover 60> 1, the cut surface cover 60 covers the cut surface 30a of the first decorative cover 30 and is generally plate-shaped. The cut surface cover 60 is generally rectangular in a front view and is longer in the width direction of the cover body 31 of the first decorative cover 30. The longitudinal edge of the cut surface cover 60 is formed with an inclined portion that is inclined toward the back side as it approaches the outside, and a protruding portion that protrudes from the inclined portion toward the back side. The cut surface cover 60 is integrally formed from a hard resin material by injection molding.

[0027] <Band Base 70> 1 to 3, the band base 70 is fixed to the bottom surface 22a of the first base member 20 and has a cable tie 103 (see FIG. 16) inserted therethrough. The band base 70 cooperates with the cable tie 103 to hold the pipe 101 at the bottom surface 22a.

[0028] 4, the band base 70 has a base portion 71 fixed to the bottom surface 22a of the first base member 20, and a support portion 72 that receives the pipe 101. Furthermore, the band base 70 has a band passage 73 formed between the base portion 71 and the support portion 72, through which the cable tie 103 is inserted (see FIG. 16).

[0029] The band base 70 has a structure that is rotationally symmetric about an axis P that passes through the center of the base portion 71 and is perpendicular to the base portion 71. Therefore, a plan view of the band base 70 is the same as the bottom view of the band base 70 shown in Fig. 6, and a right side view of the band base 70 is the same as the left side view of the band base 70 shown in Fig. 7.

[0030] 5, the base portion 71 has a rectangular shape when viewed from the front. A pair of corners 71a at diagonal positions of the base portion 71 are right-angled, while the remaining pair of corners 71b are rounded into an arc shape when viewed from the front. In this embodiment, the pair of corners 71b are located at the upper left and lower right when viewed from the front when attached to the first base member 20. A pair of fitting projections 71c are formed on both ends of the surface of the base portion 71 in the longitudinal direction.

[0031] 8 and 9, a slot 71d that is long in the longitudinal direction of the base portion 71 is formed in the center of the base portion 71. The slot 71d forms a part of the band passage 73. Four slots 71e are formed in the back surface of the base portion 71.

[0032] 4 to 6, the support part 72 is provided in the center of the base part 71 in the longitudinal direction, and is provided across the entire width of the base part 71. The support part 72 has a support surface 72a on its surface that supports the pipe 101. The support surface 72a is a concave curved surface having an arc-shaped cross section.

[0033] The band passage 73 has an entrance 74 through which the tip of the cable tie 103 is inserted and an exit 75 through which the tip of the cable tie 103 is fed. In this embodiment, when the band base 70 is attached to the first base member 20, the right opening of the band passage 73 functions as the entrance 74, and the left opening of the band passage 73 functions as the exit 75.

[0034] As shown in Figures 4 and 9, in the base portion 71, at positions facing the inlet 74 and outlet 75 of the band passage 73, guide portions 76 are provided to direct the inlet 74 and outlet 75, respectively, in the direction opposite the bottom surface 22a of the first base member 20.

[0035] 4 and 5, a first side wall portion 77 and a second side wall portion 78 that define the band passage 73 together with the guide portion 76 and the support portion 72 are provided between the base portion 71 and the support portion 72 near the entrance 74 and the exit 75 of the band passage 73. In this embodiment, when the band base 70 is attached to the first base member 20, the first side wall portion 77 is located above the entrance 74 and below the exit 75, and the second side wall portion 78 is located below the entrance 74 and above the exit 75.

[0036] The first and second sidewall portions 77, 78 are formed with support surfaces 77a, 78a, respectively, continuing to the support surface 72a of the support portion 72. These support surfaces 77a, 78a are concave curved surfaces continuing to the concave curved surface of the support surface 72a of the support portion 72. In the longitudinal direction of the band base 70, the support surfaces 77a, 78a of the first and second sidewall portions 77, 78 at least partially overlap with the inlet 74 and the outlet 75.

[0037] 5, in a front view, the support portion 72, the guide portion 76, and the first and second side wall portions 77, 78 form a generally rectangular shape, and more specifically, form a rectangular shape with a notch 79 formed at a position corresponding to the rounded corner portion 71b of the base portion 71. The notch 79 is formed across the support portion 72 and the second side wall portion 78. A plurality of mounting projections 80 are formed on the band base 70. In this embodiment, a total of eight mounting projections 80 are provided, each set consisting of four pairs of mounting projections 80.

[0038] Next, a configuration for increasing the directivity of the cable tie 103 inserted in the band base 70 will be described in detail. In the guide portion 76, at positions facing the inlet 74 and the outlet 75, an inclined surface 76a is formed that is inclined so as to move away from the bottom surface 22a and away from the support portion 72. A tip 76b of the guide portion 76 extends to a position farther from the bottom surface 22a than a vertex 72b of the concave curved surface of the support surface 72a.

[0039] 9, protrusions 81 protruding toward the guide part 76 are provided on the support part 72 at positions facing the inlet 74 of the band passage 73 and at positions facing the outlet 75. The passage cross-sectional area of ​​the band passage 73 is narrowed in the portion where the guide part 76 and the tip 81a of the protrusion 81 face each other.

[0040] The distance from the tip 81a of the protrusion 81 to the guide portion 76 is shorter than the distance from the tip 81a of the protrusion 81 to the bottom surface 22a of the first base member 20. That is, in the band passage 73, the passage cross-sectional area is smaller between the protrusion 81 and the guide portion 76 than between the protrusion 81 and the bottom surface 22a. That is, the points where the passage cross-sectional area is smallest in the band passage 73 defined by the protrusion 81 are located near the edge of the inlet 74 and near the edge of the outlet 75.

[0041] A tip 81a of the protruding portion 81 is located closer to the bottom surface 22a of the first base member 20 than a tip 76b of the guide portion 76. In the protruding portion 81, at a position facing the inlet 74 and the outlet 75, an inclined surface 81b is formed that is inclined so as to move away from the guide portion 76 as it moves away from the bottom surface 22a.

[0042] The back surface 72c of the support portion 72 defines the band passage 73 from the entrance 74 to the exit 75, and is generally convex toward the bottom surface 22a of the first base member 20. An apex 72d of the convex surface of the back surface 72c extends to a position closer to the bottom surface 22a than the protruding portion 81. Therefore, the cross-sectional area of ​​the band passage 73 is narrowed at the portion where the apex 72d faces the bottom surface 22a. The concave surface of the support surface 72a extends to a position closer to the bottom surface 22a than the protruding portion 81.

[0043] Wall surfaces 77b, 78b that define the band passage 73 are formed in the first side wall portion 77 and the second side wall portion 78 at positions facing the entrance 74 and the exit 75. The wall surfaces 77b, 78b extend to positions farther from the bottom surface 22a of the first base member 20 than the inclined surface 81b of the protruding portion 81 and the inclined surface 76a of the guide portion 76. In other words, the wall surfaces 77b, 78b that guide the movement of the cable tie 103 in the width direction extend long near the entrance 74 and the exit 75 of the band passage 73. The band base 70 is integrally molded from a hard resin material by injection molding.

[0044] <Construction method> Next, a method for installing the piping cover 10 will be described with reference to Fig. 2 and Fig. 10 to Fig. 16. In this embodiment, a method for installing the piping cover 10 that houses the piping members 100 extending upward from piping arranged under the floor of a house or the like, that is, from so-called underfloor piping, will be described.

[0045] First, as shown in Fig. 10, a slit 91 extending in the up-down direction is formed in a wall 90. The slit 91 extends to the bottom of the wall 90. A baseboard 93 extending in the width direction of the slit 91 (the horizontal direction in the figure) is fixed to the bottom of the surface of the wall 90 with a nail or the like (not shown). The lower end of the slit 91 is covered from the front side by the baseboard 93. The upper end of the slit 91 is formed in an arc shape when viewed from the front.

[0046] Next, a pair of splints 92 are fixed to the rear surface of the wall 90 along the extension direction of the slit 91. More specifically, splints 92 made of a pair of square timbers are fixed to both sides of the wall 90 in the width direction of the slit 91. Screws 94 are inserted from the front side into holes 90a formed in the wall 90 and screwed into the splints 92, thereby fixing the splints 92 to the wall 90.

[0047] 11, the second base member 40 is inserted into the upper portion of the slit 91, and the flange portions 47 are fixed to the wall 90 in such a manner that the wall 90 is sandwiched between the second base member 40 and the splint 92. The opening 41a of the accommodation recess 41 opens toward the front side of the wall 90, and the pair of flange portions 47 are fixed to the wall 90 in a state where they are overlapped on the surface of the wall 90. More specifically, the screws 95 are inserted into the screw holes 48 of the flange portions 47 from the front side, and the screws 95 are screwed into the wall 90 and the splint 92, thereby fixing the second base member 40 to the wall 90.

[0048] Next, the accommodating recess 21 of the first base member 20 is inserted into the lower part of the slit 91, and the flange portion 27 is fixed to the wall 90 in a manner that the wall 90 is sandwiched between the accommodating recess 21 and the splint 92. The opening 21a of the accommodating recess 21 opens toward the front side of the wall 90, and the pair of flange portions 27 are fixed to the wall 90 in a state where they are overlapped on the surface of the wall 90. More specifically, the screw 96 is inserted into the screw hole 28 of the flange portion 27 from the front side, and the screw 96 is screwed into the wall 90 and the splint 92, thereby fixing the first base member 20 to the wall 90. An upper end of the accommodating recess 21 of the first base member 20 overlaps with the front side of the extending portion 44 of the second base member 40 .

[0049] Next, the two band bases 70 are attached to the accommodation recess 21, and the cable ties 103 are inserted into the band passages 73 of the band bases 70. The attachment of the band bases 70 and the insertion of the cable ties 103 will be described in detail later.

[0050] 12, the pipe 101 is accommodated in the accommodating recess 21 of the first base member 20, and the joint 102 is accommodated in the accommodating recess 41 of the second base member 40. At this time, the pipe 101 is supported by the two band bases 70 attached to the accommodating recess 21. Specifically, as shown in FIG. 16, the pipe 101 is fastened to the band base 70 via a cable tie 103 (not shown in FIGS. 12 and 13) inserted into the band passage 73 of the band base 70.

[0051] In addition, the mounting seat of the joint 102 is engaged with a pair of engagement portions 46 of the second base member 40, and a screw 97 is inserted into the mounting seat of the joint 102 and screwed into the screw hole 45 of the accommodating recess 41, thereby fixing the joint 102 to the accommodating recess 41.

[0052] 13, the first decorative cover 30 is assembled to the first base member 20. Next, the second decorative cover 50 is assembled to the second base member 40. As a result, the cut surface 30a at the upper end of the first decorative cover 30 is covered by the second decorative cover 50.

[0053] Also, a cut surface cover 60 is attached so as to cover the cut surface 30a at the lower end of the first decorative cover 30. The cut surface cover 60 is fixed to the surface of the first decorative cover 30 via, for example, double-sided tape or adhesive.

[0054] As shown in Figures 14(a) and 14(b), the protruding heights of the first decorative cover 30, the second decorative cover 50 and the cut surface cover 60 from the surface of the wall 90 are less than the protruding height of the baseboard 93 from the surface of the wall 90.

[0055] Next, the procedure for attaching the band base 70 to the first base member 20 will be described in detail. 2, with the longitudinal direction of the band base 70 aligned with the longitudinal direction of the first base member 20, the band base 70 is rotated 90 degrees clockwise in a front view while being abutted against the bottom surface 22a of the bottom wall 22. As a result, both longitudinal ends of the base portion 71, more specifically, the portions provided with the pair of fitting projections 71c, are fitted between the bottom wall 22 of the first base member 20 and the pair of first ridges 24. During this assembly work, the worker can use the multiple assembly projections 80 as anti-slip.

[0056] As described above, the pair of corners 71b of the base portion 71 are rounded into an arc shape when viewed from the front, and the notches 79 are provided at positions corresponding to the corners 71b. This allows the band base 70 to rotate clockwise when viewed from the front from the position shown by the two-dot chain line in FIG.

[0057] When the band base 70 is rotated to the normal assembly position shown by the solid lines in FIG. 2, the pair of corners 71a come into contact with the pair of side walls 23, thereby preventing the band base 70 from rotating any further.

[0058] 15, both longitudinal ends of the base portion 71 are fitted between the bottom wall 22 and the pair of first protrusions 24 of the first base member 20, thereby attaching the band base 70 to the first base member 20. Also, the gap between the base portion 71 and the pair of side walls 23 is very small, so that the band base 70 is prevented from shifting relative to the first base member 20 even when a large force is applied in the left-right direction.

[0059] On the other hand, rotation of the band base 70 in a counterclockwise direction when viewed from the front from the position shown by the two-dot chain line in Figure 2 is prevented by the pair of first side wall portions 77 abutting against the pair of first protrusions 24.

[0060] Next, the procedure for inserting the cable tie 103 into the band passage 73 will be described in detail with reference to FIG. First, the tip of the cable tie 103 is inserted into the entrance 74. Specifically, the tip of the cable tie 103 is pushed between the support portion 72 and the guide portion 76, between the first side wall portion 77 and the second side wall portion 78. The tip of the cable tie 103 abuts against the bottom surface 22a of the first base member 20, and is directed toward the center side of the band passage 73 (the rear surface 72c side of the support portion 72) by the guide portion 76 on the entrance 74 side. Here, since the cable tie 103 is elastically deformable and has a certain degree of rigidity, the surface of the cable tie 103 opposite to the surface on the guide portion 76 side is in contact with the protrusion 81 on the entrance 74 side, and the cable tie 103 is also directed by the protrusion 81.

[0061] When the tip of the cable tie 103 passes through the portion between the back surface 72c and the bottom surface 22a in the band passage 73, it hits the guide portion 76 on the outlet 75 side and is directed by the guide portion 76 to the opposite side from the bottom surface 22a. At this time, the surface of the cable tie 103 opposite to the surface on the guide portion 76 side is in contact with the protrusion 81 on the outlet 75 side, and the cable tie 103 is also directed by the protrusion 81. In this way, the tip of the cable tie 103 is sent out from the outlet 75. Specifically, the tip of the cable tie 103 is sent out from between the support portion 72 and the guide portion 76, between the first side wall portion 77 and the second side wall portion 78.

[0062] Thereafter, the tip of the cable tie 103 abuts against the side wall 23 of the first base member 20, and as it is further advanced toward the side opposite the bottom surface 22a, it comes into contact with the second ridge 25 of the first base member 20. The inclined surface 25a of the second ridge 25 directs the cable tie 103 in a direction away from the side wall 23, and the tip of the cable tie 103 is further advanced toward the side opposite the bottom surface 22a without being caught by the third ridge 26. In this manner, the insertion of the cable tie 103 into the band passage 73 is completed. As shown in FIG. 16, the inserted cable tie 103 cooperates with the band base 70 to hold the pipe 101.

[0063] Next, the function and effect of the band base 70 of this embodiment will be described. (1) A protrusion 81 protruding toward the guide portion 76 is provided at a position of the support portion 72 facing the outlet 75 of the band passage 73, and the cross-sectional area of ​​the band passage 73 is narrowed in the opposing portion between the guide portion 76 and the tip 81a of the protrusion 81. The narrow cross-sectional area of ​​the band passage 73 makes it easier to determine the direction in which the cable tie 103 is fed out from the outlet 75. This makes it easier to insert the cable tie 103 into the band base 70, and facilitates the work of holding the pipe 101.

[0064] (2) In the vicinity of the outlet 75, the wall surfaces 77b, 78b of the first and second side wall portions 77, 78 extend to a position farther from the bottom surface 22a of the first base member 20 than the inclined surface 81b of the protrusion portion 81 and the inclined surface 76a of the guide portion 76. When the cable tie 103 is fed out from the outlet 75, it passes between the wall surfaces 77b, 78b of the first and second side wall portions 77, 78, which extend relatively long as described above. At this time, the two wall surfaces 77b, 78b make it easier to determine the feeding direction of the cable tie 103 in the width direction. Therefore, the operation of inserting the cable tie 103 into the band base 70 becomes smooth, and the operation of holding the pipe 101 can be made easier.

[0065] (3) The apex 72d of the convex curved surface of the back surface 72c of the support portion 72 extends to a position closer to the bottom surface 22a than the protruding portion 81. Therefore, the cross-sectional area of ​​the band passage 73 is narrowed at the position of the apex 72d, and the passing direction of the cable tie 103 becomes more stable. Therefore, the operation of inserting the cable tie 103 into the band base 70 becomes smooth, and the operation of holding the pipe 101 can be made easier.

[0066] (4) The apex 72b of the concave curved surface of the support surface 72a extends to a position closer to the bottom surface 22a than the protruding portion 81. That is, the support surface 72a is closer to the bottom surface 22a, and therefore the pipe 101 disposed on the support surface 72a is also closer to the bottom surface 22a. This makes it possible to reduce the distance that the pipe 101 protrudes vertically from the bottom surface 22a, thereby saving space.

[0067] (5) The first and second side wall portions 77, 78 are formed with support surfaces 77a, 78a, respectively, continuing to the support surface 72a of the support portion 72. The support surfaces 77a, 78a of the first and second side wall portions 77, 78 are concavely curved surfaces continuing to the concavely curved surface of the support surface 72a of the support portion 72. When holding a pipe 101 having a diameter larger than the width of the support portion 72, the pipe 101 is supported not only by the support surface 72a of the support portion 72 but also by the support surfaces 77a, 78a of the first and second side wall portions 77, 78. Therefore, the pipe 101 can be held more stably.

[0068] <Modification> The above embodiment can be modified, for example, as follows: The above embodiment and the following modified examples can be combined with each other to the extent that no technical contradiction occurs.

[0069] The support surface 72a of the support portion 72 does not have to be a concave curved surface. For example, the support surface 72a may be formed from a single plane, or may be formed from a plurality of planes that are inclined and connected to each other.

[0070] The rear surface 72c of the support portion 72 does not have to be a convex curved surface. For example, the rear surface 72c may be formed from a single plane, or may be formed from a plurality of planes that are inclined and connected to each other.

[0071] The inclined surface 76a of the guide portion 76 may be curved. In this case, it may be a concave curved surface or a convex curved surface. The surfaces of the guide portion 76 facing the inlet 74 and the outlet 75 do not have to be the inclined surfaces 76a as in the above embodiment. For example, the surfaces of the guide portion 76 facing the inlet 74 and the outlet 75 may be flat surfaces perpendicular to the bottom surface 22a, which is the installation surface.

[0072] In the above embodiment, when the band base 70 is attached to the first base member 20, the right opening of the band passage 73 functions as the inlet 74, and the left opening of the band passage 73 functions as the outlet 75. Alternatively, the right opening of the band passage 73 may function as the outlet, and the left opening of the band passage 73 may function as the inlet.

[0073] In the above embodiment, the rotation of the band base 70 in the counterclockwise direction in front view from the attitude shown by the two-dot chain line in Fig. 2 is prevented by the pair of first side wall portions 77 abutting against the pair of first protrusions 24. Alternatively, the rotation of the band base 70 in the counterclockwise direction in front view may be prevented by the pair of corner portions 71a abutting against the pair of side walls 23. For example, such a configuration can be achieved by forming notches similar to the notch portions 79 in the pair of first side wall portions 77.

[0074] The band base 70 may have a structure that is not rotationally symmetrical about an axis P that passes through the center of the base portion 71 and is perpendicular to the base portion 71. For example, the structure near the inlet 74 and the structure near the outlet 75 may be different.

[0075] The method of fixing the band base 70 is not limited to the above embodiment, and it may be fixed by other methods such as screwing or adhesive. The band base 70 does not have to be fixed to the first base member 20 of the piping cover 10. For example, the band base 70 may be fixed to a cover other than the piping cover 10. Alternatively, the band base 70 may be directly attached to a wall, floor, ceiling, pillar, or the like. [Explanation of symbols]
