Description

[Technical field]

[0001] The present invention relates to a wiring lead-in structure for a building. [Background technology]

[0002] For example, solar panels are installed on the roofs of buildings such as detached houses and apartment buildings. The wiring extending from the solar panels installed on the roofs is led into the interior of the building (see, for example, Patent Document 1 and Patent Document 2).

[0003] When leading the wiring from the solar panels into the interior of a building, the mainstream method is to attach a wiring entrance box to the exterior wall of the building and run the wiring through the exterior wall wiring entrance box. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2015-102882 A [Patent Document 2] JP 2011-018865 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, if the wiring extending from the solar panels is led into the interior of the building through an incoming wiring box attached to the exterior wall of the building, it becomes necessary to attach the incoming wiring box to the exterior wall, and there is a problem that the incoming wiring box deteriorates the appearance of the building.

[0006] In addition, since the number of wires that can be passed through the entrance box is limited, if more solar panels are installed to increase the amount of power generated, the number of wires increases, and therefore more entrance boxes must be installed on the exterior wall. Therefore, the problem of poor appearance described above becomes more pronounced the more solar panels are installed.

[0007] Therefore, a main object of the present invention is to contribute to improving the above-mentioned problems. [Means for solving the problem]

[0008] In response to the above problems, the present invention provides: A roof panel is installed on the upper part of the building body so as to be located inside the upper edge of the building body, For a building in which a roof edge cover is installed between the building body and the roof panel to cover the upper edge of the building body and the side of the roof panel, A wiring lead-in structure of a building that leads wiring extending from a solar panel installed on the roof panel to the inside of the building, An opening for wiring is formed in the roof edge cover, The wiring is characterized in that it is led to the underside of the roof panel through the opening. Effect of the Invention

[0009] According to the present invention, the above-mentioned configuration makes it possible to eliminate the entrance box on the exterior wall and prevent the entrance box from spoiling the appearance. [Brief description of the drawings]

[0011] Hereinafter, the present embodiment will be described in detail with reference to the drawings. 1 to 9 are intended to explain this embodiment. EXAMPLES

[0012] <Configuration> The configuration of this embodiment will now be described.

[0013] FIG. 1 is a plan view of a building 1 seen from above. The building 1 of this embodiment has a roof panel 3 installed on the top of a building main body 2. The roof panel 3 is installed so that at least one side is located inside the upper edge 2a of the building main body 2. Between the building body 2 and the roof panel 3, a roof edge cover 4 is installed which covers the upper edge 2a of the building body 2 and the side surface 3a of the roof panel 3.

[0014] Here, the building 1 may be of any type, such as a detached house or an apartment building. The building 1 may also be of any structure, such as wood or steel frame construction. In this embodiment, the building 1 is a unit building. A unit building is a building 1 that can be constructed in a short period of time by transporting building units 5 (FIG. 2) manufactured in advance in a factory to a construction site and assembling multiple units at the construction site.

[0015] The building body 2 is a component that constitutes the main body of the building 1. In the case of a unit building, the building body 2 is formed by arranging one or more building units 5 side by side or stacking them one on top of the other.

[0016] As shown in Figure 2, the building unit 5 has a box-frame rigid-frame unit frame as its skeleton, in which the upper ends of four pillars 6 are connected in a rectangular shape by four ceiling beams 7, and the lower ends of the four pillars 6 are connected in a rectangular shape by four floor beams 8.

[0017] The upper edge 2a of the building main body 2 refers to the edge (peripheral edge) along the periphery of the building main body 2 at the upper part of the building main body 2. The upper part of the building main body 2 is the position of the ceiling beams 7 of the building unit 5 on the top floor. The upper surface of the building main body 2 is covered with the ceiling surface.

[0018] The roof panel 3 is a panel for constructing a roof. A plurality of roof panels 3 are arranged and installed on the upper surface of the building main body 2 so as to cover almost the entire upper surface of the building main body 2, thereby constructing a roof on the building main body 2.

[0019] The roof panel 3 can have a structure in which a roof surface material 12 is installed between a pair of parallel roof frames 11 as shown in Fig. 3, for example. The roof frame 11 is formed of a long metal material with an inward C-shaped cross section. The roof surface material 12 has a wooden underlayment 13, a waterproof sheet, and a water-resistant metal finishing surface material 15. The roof surface material 12 is installed on the pair of roof frames 11 with a required drainage gradient that descends from the inside to the outside of the building body 2. The roof surface material 12 is installed on top of cross rail members 16 that are attached to the inner surface of the roof frame 11 in a downward inclination.

[0020] In addition, the "space" between the building main body 2 and the roof panel 3 is not limited to the narrow meaning of the specific "space" formed between the building main body 2 and the roof panel 3, but also includes an abstract meaning such as the mutual relationship between the building main body 2 and the roof panel 3.

[0021] Being located inside the upper edge 2a means that, as shown in Figures 4 and 5 (mainly Figure 5), the roof panel 3 (its side surface 3a as a whole) is installed so as not to protrude outward from the top surface (upper edge portion 2a) of the building main body 2. It is preferable that all side surfaces 3a of the roof panel 3 are located inside the upper edge portion 2a, but it is sufficient that at least one or more side surfaces 3a are located inside the upper edge portion 2a.

[0022] The side surface 3a of the roof panel 3 is the surface of the outermost installed roof panel 3 that constitutes the side closest to the upper edge 2a of the building main body 2. Since the roof panel 3 has a required thickness, the side surface 3a has a step with respect to the upper surface of the building main body 2 by a height equal to the above thickness.

[0023] The roof edge cover 4 is a substantially strip-shaped member that covers from above the long and narrow edge portion between the side surface 3a of the roof panel 3 along the upper edge 2a on the upper surface of the building main body 2. The roof edge cover 4 can be installed on each side that constitutes the upper edge 2a of the building main body 2. The roof edge cover 4 is made of metal and is water-resistant and waterproof.

[0024] The roof edge cover 4 has at least a main surface 4a along the upper surface of the building body 2, and a vertical surface 4b rising upward from the inner edge of the main surface 4a along the side surface 3a (outer surface) of the roof panel 3. The roof edge cover 4 also has a horizontal surface 4c extending slightly laterally from the upper end of the vertical surface 4b toward the inside of the roof panel 3 along the upper part of the side surface 3a of the roof panel 3. The roof edge cover 4 has a step shape by having the main surface 4a, the vertical surface 4b, and the horizontal surface 4c. The main surface 4a and the horizontal surface 4c are surfaces that face approximately in the vertical direction, and the vertical surface 4b is a surface that faces approximately in the inside and outside direction of the building 1. The main surface 4a, the vertical surface 4b, and the horizontal surface 4c can be formed, for example, by bending a single metal plate. The main surface 4a has a drainage slope that descends toward the outside of the building body 2. The roof edge cover 4 is attached to the upper part of the building main body 2 via one or more mounting members 17-19.

[0025] For the basic configuration above, A solar panel 21 is installed on the roof panel 3. Then, wiring such as a wiring 22 and a ground wire extending from the solar panel 21 is led into the interior of the building 1.

[0026] Here, the solar panel 21 is a planar electric element that converts solar energy into electricity. The solar panel 21 is attached to and integrated with the upper surface of the roof panel 3 (on top of the roof surface material 12).

[0027] The wiring 22 is connected to each solar panel 21. A plurality of wirings 22 are installed according to the number of solar panels 21 installed.

[0028] 1, a metallic decorative and waterproof panel cover 25 is installed between adjacent roof panels 3, and a ridge cover 26 is installed on the central ridge portion of the roof. By passing the wiring 22 from the solar panels 21 under the panel cover 25 and ridge cover 26, the panel cover 25 and ridge cover 26 become a wiring concealment cover 27.

[0029] Both ends of the ridge cover 26 extend to the position of the roof edge cover 4 on the upper edge 2a of the building main body 2, and the wiring 22 from the solar panel 21 passes through the inside of the wiring concealment cover 27 and is led to the position of the roof edge cover 4. The wiring 22 is then guided along the roof edge cover 4 to the position of the attic inspection hatch 28 formed on the top surface of the building main body 2. The attic inspection hatch 28 is formed in a position close to the roof edge cover 4.

[0030] The wiring 22 is led into the building 1 in order to connect it to various power system devices, such as a power conditioner and a distribution board (not shown), installed inside the building 1. However, contrary to the above, the wiring from the power system devices may be led up to the roof and connected to the wiring 22 of the solar panel 21 on the roof.

[0031] The wiring lead-in structure (from the roof to the inside of the building body 2) of the building 1 in this embodiment may have the following configuration.

[0032] (1) As shown in FIG. 6, the roof edge cover 4 may be provided with an opening 32 that constitutes a wiring lead-in portion 31. The wiring 22 may be led through an opening 32 to the underside 33 of the roof panel 3 (FIG. 5).

[0033] Here, the wiring lead-in portion 31 is a penetration portion formed in the roof edge cover 4 so that the wiring 22 can be led from above the roof into the interior of the building 1. The wiring lead-in portion 31 is formed in a position close to the attic inspection hatch 28 formed on the top surface (ceiling surface) of the building main body 2, and is used together with the attic inspection hatch 28 to lead in the wiring 22. The wiring 22 is led from the wiring lead-in portion 31 to the underside of the roof, and then led into the interior of the building main body 2 through the attic inspection hatch 28.

[0034] The opening 32 constitutes the main part of the wiring lead-in part 31 and is a through hole formed in the roof edge cover 4. The opening 32 is formed in the main surface 4a of the roof edge cover 4 so as to penetrate the boundary part with the vertical surface 4b from top to bottom. The opening 32 may have any shape, but in this embodiment, it is substantially rectangular in plan view. The opening 32, which is substantially rectangular in plan view, has a width that is approximately half the width dimension of the main surface 4a and a required length that is equal to or longer than this width.

[0035] The underside 33 of the roof panel 3 is a portion located below the roof panel 3 and facing the upper surface of the building main body 2. The upper surface of the building main body 2 is blocked off by the ceiling surface, but since the attic inspection hatch 28 is formed in the ceiling surface, if the wiring 22 can be led to the underside 33 of the roof panel 3, it will be possible to lead it directly into the interior of the building 1 through the attic inspection hatch 28.

[0036] (2) A wiring inlet cover 41 that surrounds the opening 32 may be attached to the wiring inlet portion 31 on top of the roof edge cover 4. The wiring inlet cover 41 may be covered from above with a lid member 42 (FIG. 7).

[0037] Here, the wiring inlet cover 41 is a metal member that protects the periphery of the opening 32 of the wiring inlet section 31, and constitutes a part of the wiring inlet section 31. The wiring inlet cover 41 is a frame member that is substantially C-shaped in plan view, with one rectangular side open and three sides that are substantially perpendicular to each other, by forming the opening 32 at the position of the boundary with the vertical surface 4b. The open portion of the wiring inlet cover 41 is blocked by joining both ends to the vertical surface 4b of the roof edge cover 4.

[0038] The wiring inlet cover 41 is integrated with the roof edge cover 4 by having its bottom portion joined to the upper surface of the main surface 4a of the roof edge cover 4. The wiring inlet cover 41 is joined and fixed to the roof edge cover 4 (the main surface 4a and the vertical surface 4b) by welding, riveting, or the like. Necessary joint allowances are appropriately formed at the joint portions. It is preferable that the wiring inlet cover 41 is made in the same color tone as the roof edge cover 4.

[0039] The cover member 42 (FIG. 7) is a metal protective member that is attached to the top of the wiring inlet cover 41 from above to cover the entire opening 32, and constitutes a part of the wiring inlet section 31. The cover member 42 has a planar shape that is almost the same as the opening 32 and the wiring inlet cover 41, and mainly has a cover surface 42a that is slightly or slightly larger than the opening 32 and the wiring inlet cover 41 and faces almost vertically. The cover surface 42a is installed at the upper position of the wiring inlet cover 41, lower than the side surface 4c of the roof edge cover 4. The cover surface 42a may be inclined so as to have a drainage gradient similar to that of the main surface 4a of the roof edge cover 4 and to have a downward gradient toward the outdoor side. The cover member 42 is preferably in the same color tone as the roof edge cover 4.

[0040] The lid member 42 has a fitting locking portion 42b on one side facing the inside (roof side) of the building main body 2. This fitting locking portion 42b is an inverted U-shaped portion with a width dimension slightly larger than the side surface 4c of the roof edge cover 4. By fitting and locking this fitting locking portion 42b to the side surface 4c of the roof edge cover 4 from above, the lid member 42 is positioned and held relative to the roof edge cover 4.

[0041] The fitting locking portion 42b may extend over the entire area of ​​one side, or one or more fitting locking portions may be provided partially on one side. The fitting locking portion 42b may be formed integrally with the cover member 42, or may be formed separately and attached. The fitting locking portion 42b may be formed integrally with the cover member 42, or may be formed separately and attached.

[0042] The cover member 42 has a cover surface 42a that is appropriately fixed to the wiring lead-in cover 41 in the vertical or horizontal directions by a fastener 45 such as a rivet.

[0043] Then, an elastically deformable solid water stop material 46 such as rubber or a paste-like water stop agent 47 is appropriately applied between the upper surface of the wiring inlet cover 41 and the lower surface of the lid member 42. The water stop material 46 and the water stop agent 47 are provided so as to be continuous at least along the upper part of the wiring inlet cover 41. The water stop material 46 and the water stop agent 47 may be provided on the lower surface side of the lid member 42. The water stop material 46 and the water stop agent 47 may also be provided on the parts of the vertical surface 4b and the horizontal surface 4c of the roof edge cover 4 where the fitting locking portion 42b fits.

[0044] (3) As shown in Figure 8, The wire inlet cover 41 may have a rising portion 51 rising toward the opening 32 and a wire passing portion 52 provided above the rising portion 51 . The cover member 42 may have, at least on the portion on the side of the wire passing portion 52 , a rising portion 53 that is positioned outside the wire passing portion 52 and extends downward beyond the wire passing portion 52 .

[0045] Here, the rising portion 51 constitutes the main portions of the three sides of the open frame-shaped wiring pull-in cover 41, and is a standing wall that rises to a height that is approximately half or more of the vertical surface 4b of the roof edge cover 4. The rising portion 51 is made higher than the height that can prevent water from running down from the wiring 22 from entering the opening 32. The upper side of the rising portion 51 refers to the portion above half the height dimension of the rising portion 51.

[0046] The wire passing portion 52 is a portion that passes the wires 22 from the outside to the inside of the wire inlet cover 41. The wire passing portion 52 is provided in the rising portion 51 located on the wire concealment cover 27 (ridge cover 26) side of the wire inlet cover 41. The wire passing portion 52 can be, for example, a concave cutout portion formed along the upper edge portion of the rising portion 51, or a through hole formed in the upper portion of the rising portion 51. In this embodiment, the wire passing portion 52 is a cutout portion.

[0047] Specifically, the wiring inlet cover 41 has a substantially horizontal outer flange 55 formed integrally with the upper edge of each rising portion 51 that forms three sides, and the above-mentioned waterproofing material 46 and waterproofing agent 47 are installed on the upper surface of the outer flange 55 (FIG. 6(a)). A lower flange 56 for draining water is formed integrally with the outer edge of the outer flange 55, and a hemmed portion 56a is formed at the lower edge of the lower flange 56 by folding it back upward so as not to damage the wiring 22.

[0048] The wire passing portion 52 is formed by cutting out a part or the whole of the upper side of the rising portion 51 to a required width to accommodate the wires 22. In order to ensure watertightness, the wires 22 are arranged side by side (in an orderly manner) in the wire passing portion 52 so as not to overlap or cross each other vertically (FIG. 6(b)). In the wire passing portion 52, the wires 22 are sandwiched between the water-stopping materials 46 from above and below and passed between the water-stopping materials 46, so that the upper and lower water-stopping materials 46 provide watertightness.

[0049] In addition, in locations other than the wiring pass-through portion 52, multiple wirings 22 may be bundled together, and the bundled wirings 22 may be fixed to an appropriate location such as the inner surface of the roof frame 11 with tape 57 (Figure 6(c)).

[0050] The rising portion 53 is a downward flange portion that is integrally provided on an edge portion of the lid member 42 that protrudes outward beyond the wiring pull-in cover 41. The rising portion 53 is formed in a continuous state along the three sides other than the side where the fitting locking portion 42b is provided.

[0051] Among these, at least on the side of the wire passing portion 52, the rising portion 53 is formed outside the lower flange 56 of the wire lead-in cover 41 so as to be separated from the lower flange 56 with a required wire passing space. Also, the lower edge portion of this rising portion 53 is extended to an upper position with the required wire passing space with respect to the main surface 4a of the roof edge cover 4. The required wire passing space is set to a size of the distance of the diameter of the wire 22 plus a margin.

[0052] At least in the portion where the wire-passing space is formed, the rising portion 53 has a hemmed portion 53a formed by folding back upward so as not to damage the wiring 22 at its lower edge. Alternatively, by forming the hemmed portion 53a, the rising portion 53 secures and forms a wire-passing space below its lower edge. Note that in the portion where the wire-passing space is not provided, the lower edge of the rising portion 53 may be extended to a length that almost reaches the main surface 4a of the roof edge cover 4 without forming the hemmed portion 53a. This makes the lower edge of the rising portion 53 step-shaped between the wire-passing space portion and the other portion (FIG. 7).

[0053] Then, the wiring 22 led from the end of the wiring concealment cover 27 to the wiring lead-in portion 31 along the main surface 4a of the roof edge cover 4 is guided from the outside to the inside of the wiring lead-in cover 41. At this time, the wiring 22 passes horizontally from the outside of the wiring lead-in portion 31 through the upper and lower gaps between the main surface 4a of the roof edge cover 4 and the lower edge of the rising portion 53. Next, the wiring 22 passes upward through the inner and outer gaps between the rising portion 53 and the lower flange 56 of the wiring lead-in cover 41, and enters the opening 32 after climbing over the wiring passage portion 52, thereby forming an upward detouring shape. The wiring space formed by the upper and lower gaps between the main surface 4a of the roof edge cover 4 and the lower edge of the rising portion 53 and the inner and outer gaps between the rising portion 53 and the lower flange 56 of the wiring lead-in cover 41 is almost labyrinth-shaped.

[0054] (4) As shown in Figures 4 and 5, a wiring protection cover 61 may be attached to the roof edge cover 4 to cover from above the wiring 22 that is led along the side surface 3a of the roof panel 3 to the opening 32.

[0055] Here, the wiring protection cover 61 is a long metal member that extends along the side surface 3a of the roof panel 3 and on the main surface 4a of the roof edge cover 4 in the longitudinal direction of the roof edge cover 4. The wiring protection cover 61 is an L-shaped cross-sectional member having a horizontal surface portion 61a and a vertical surface portion 61b, and connects between the wiring concealment cover 27 (ridge cover 26) and the wiring lead-in portion 31. The wiring protection cover 61 is preferably made in the same color tone as the roof edge cover 4. By placing the wiring protection cover 61 on the roof edge cover 4, a passage for passing the wiring 22 is formed between the horizontal surface portion 61a and the vertical surface portion 61b of the wiring protection cover 61 and the main surface 4a and the vertical surface 4b of the roof edge cover 4.

[0056] The horizontal surface portion 61a of the wiring protection cover 61 is narrower than the main surface 4a of the roof edge cover 4 and the cover surface 42a of the cover member 42. The horizontal surface portion 61a has a drainage gradient that slopes downward toward the outside of the building main body 2. The vertical surface portion 61b of the wiring protection cover 61 has a height approximately equal to the vertical surface 4b of the roof edge cover 4, so that the horizontal surface portion 61a is approximately flush with the horizontal surface 4c of the roof edge cover 4. The vertical surface portion 61b may have a hemming portion 61c formed by folding it back upward at its lower portion so as not to damage the wiring 22.

[0057] <Function> The function of this embodiment will now be described.

[0058] The building 1 is constructed by placing a roof on top of the building main body 2. In the case of a unit building, a plurality of building units 5 are installed to form the building main body 2, and then a plurality of roof panels 3 are arranged on top of the building main body 2 so as to cover the upper surface of the building main body 2, thereby forming the main part of the roof. Then, the roof is formed by attaching roof edge covers 4 around the periphery of the roof panels 3 so as to cover the long and narrow gaps between the side surfaces 3a of the roof panels 3 and the building main body 2, and the building 1 is constructed.

[0059] Solar panels 21 are attached to the roof panels 3 in advance, and wiring 22 from each solar panel 21 is bundled together for each roof panel 3.

[0060] After the roof is formed, the wiring 22 of the solar panels 21 that are grouped together for each roof panel 3 is collected and all of the wiring 22 is led to the inside of the building 1.

[0061] At this time, the wiring 22 is led on the roof to a position on the edge of the roof (side surface 3a of roof panel 3) through the inside of the wiring concealment cover 27 (panel cover 25, ridge cover 26). After that, the wiring 22 is led along the edge of the roof toward the wiring lead-in portion 31 while being exposed on the roof edge cover 4. The wiring 22 is then passed through the wiring lead-in portion 31 provided on the roof edge cover 4.

[0062] The wiring entry section 31 has an opening 32, and the wiring 22 is led from the upper side of the roof edge cover 4 through the opening 32 to the underside 33 of the roof panel 3, and then led into the interior of the building main body 2 through the attic inspection hatch 28.

[0063] In the wiring lead-in portion 31, a wiring lead-in cover 41 is installed around the opening 32, and the wiring 22 passes over a rising portion 51 of the wiring lead-in cover 41, and is routed upward to the opening 32. A wiring pass-through portion 52 is provided in the rising portion 51, and the wiring 22 is passed through the wiring pass-through portion 52 and is waterproofed by a waterproofing material 46 provided in the wiring pass-through portion 52.

[0064] A lid member 42 is attached to the wiring inlet cover 41 from above, thereby closing the opening 32.

[0065] Finally, the portion of the wiring 22 exposed above the roof edge cover 4 is covered with a wiring protection cover 61.

[0066] <Effects> According to this embodiment, the following effects can be obtained.

[0067] (Effect 1) The wiring lead-in structure of the building 1 may be such that the wiring 22 is led to the underside 33 of the roof panel 3 through an opening 32 that serves as the wiring lead-in section 31 formed in the roof edge cover 4. This makes it possible to eliminate the need to attach one or more incoming wiring boxes 72 to the exterior wall 71 of the building 1, as shown in the comparative example of FIG. 9. Furthermore, by ensuring an inlet for the wiring 22 in an inconspicuous position on the edge of the roof, it is possible to prevent the appearance from being marred by the incoming wiring box 72. Furthermore, by forming the opening 32 large, a large number of wirings 22 can be passed through at once, so that there is ample room to maneuver even when a large number of solar panels 21 are installed and the amount of wiring 22 increases.

[0068] (Effect 2) The wiring pull-in structure of the building 1 may be such that the wiring pull-in cover 41 is attached on top of the roof edge cover 4 surrounding the opening 32, and the roof edge cover 4 is covered from above with the lid member 42. This allows the opening 32 to be protected by the wiring pull-in cover 41 and the lid member 42, and the opening 32 to be waterproofed. The wiring pull-in cover 41 and the lid member 42 can be installed so as not to be noticeable from the outside, preventing a deterioration in appearance.

[0069] (Effect 3) In the wiring pull-in structure of the building 1, the wiring pull-in cover 41 may have a rising portion 51 that rises toward the opening 32 and a wiring pass-through portion 52 provided above the rising portion 51. This allows the wiring 22 to be bypassed upward (routed so as to climb over the rising portion 51) by the rising portion 51 (and the wiring pass-through portion 52), and water running down the wiring 22 can be cut off at the upward bypass portion, reliably preventing the running water from entering the opening 32.

[0070] Moreover, the wire passing portion 52 allows the wires 22 to be contained within the height range of the rising portion 51. Furthermore, by applying a waterproofing material 46 to the wire passing portion 52, the cover member 42 can be attached in a state in which the wire passing portion 52 is reliably waterproofed.

[0071] Lid member 42 may have a rising portion 53 located outside wire passing portion 52 and extending downward, at least in the portion on the side of wire passing portion 52. This makes it possible to form a substantially labyrinth-shaped wire passage space between lid member 42 and wire passing portion 52 of wire inlet cover 41. Lid member 42 and rising portion 53 then cover wire passing portion 52 and the entire upward bypass portion of wire 22, thereby ensuring waterproof performance for wire inlet portion 31.

[0072] (Effect 4) The wiring lead-in structure of the building 1 may be provided with a wiring protection cover 61 attached to the roof edge cover 4, which covers the wiring 22 led to the opening 32 along the side surface 3a of the roof panel 3 from above. This ensures that the wiring 22 on the roof edge cover 4 until it enters the opening 32 is protected by the wiring protection cover 61 and cannot be seen from the outside. Furthermore, in the case of the comparative example described above, the wiring 22 needs to be led to the entrance box 72 along the exterior wall 71 while being placed in the flexible plastic tube 73, and the flexible plastic tube 73 also causes a deterioration in appearance. In contrast, in this embodiment, the flexible plastic tube 73 arranged along the exterior wall 71 is eliminated, and the appearance of the exterior wall 71 can be prevented from being deteriorated.
