Description

[Technical Field]

[0001] The present invention relates to a roof structure to which a solar cell module is attached and a cover member used for the roof structure. [Background technology]

[0002] BACKGROUND ART Conventionally, roof structures have been known in which roof members are laid on a roof substrate and solar cell modules are laid on the roof members (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-112127 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, there are cases where solar cell modules are installed not from the eaves of the roof but halfway towards the ridge of the roof. In such cases, the solar cell system of Patent Document 1 has the problem that the solar cell module is installed on the roof tiles via a mounting base consisting of vertical and horizontal racks, so the solar cell module is floating above the roof tiles by the height of the mounting base, which makes it look unattractive.

[0005] Therefore, an object of the present invention is to provide a roof structure and a cover member that have a sense of unity between the roof member and the solar cell module and that have superior design compared to conventional roof structures and cover members. [Means for solving the problem]

[0006] One aspect of the present invention for solving the above-mentioned problems is a roof structure in which a first roof member and a second roof member are arranged on a roof substrate in a stepped manner in the eaves-ridge direction, wherein the eaves-side portion of the second roof member overlaps the ridge-side portion of the first roof member, and the roof structure has a solar cell module, a retaining bracket, a mounting bracket, and a cover member, and the retaining bracket holds the eaves-side end of the solar cell module, and the mounting bracket is arranged across the first roof member and the second roof member, and the retaining bracket is fixed at a position where it overlaps with the second roof member when the solar cell module is viewed in a plane, and the cover member has a clamped portion that is clamped between the mounting bracket and the retaining bracket, and an extension portion that extends at an angle from the clamped portion toward the first roof member, and the extension portion has a free end at the eaves-side end close to the first roof member.

[0007] According to this aspect, the eaves-side end of the extension is close to the first roof element, so a unified appearance can be achieved between the first roof element on the eaves side and the solar cell module. As a result, there is a sense of unity between the roof element and the solar cell module, and the design is superior to conventional methods. According to this aspect, since the eaves side end of the extension portion is close to the first roof member, it is difficult for birds, animals, etc. to get between the solar cell module and the second roof member through the gap between the eaves side end of the extension portion and the first roof member. According to this aspect, since the eaves-side end of the extension is close to the first roof member, wind is less likely to enter between the solar cell module and the second roof member through the gap between the eaves-side end of the extension and the first roof member, and the solar cell module is less likely to be subjected to loads due to upwind forces. As a result, the solar cell module is less likely to separate from the roof substrate. According to this aspect, the eaves side end of the extension portion is a free end at a position close to the first roof member, so even if the cover member tilts due to wind load, the eaves side end of the extension portion abuts against the first roof member, preventing the cover member from coming off.

[0008] In a preferred aspect, the shortest distance between the eaves-side end of the extension and the first roof member is more than 0 mm and 3 mm or less.

[0009] According to this aspect, it is more difficult for birds, animals, etc. to enter through the gap between the eaves side end of the extension part and the first roof member.

[0010] In a preferred aspect, the cover member has a leg portion extending from midway in the extension direction of the extension portion toward the mounting bracket, and the mounting bracket has an engaging portion that is located closer to the eaves than the leg portion and engages with the leg portion in the ridge direction.

[0011] According to this aspect, the engaging portion of the mounting bracket can prevent the cover member from moving toward the eaves, making it difficult for the cover member to come off.

[0012] In a preferred aspect, the leg rests on the mounting bracket.

[0013] According to this aspect, it is possible to prevent the first roof member from being damaged by contact with the leg portion.

[0014] A preferred aspect is a fastening element having a head and a shaft, the shaft of which is inserted into the clamped portion and the mounting bracket, fixing the clamped portion to the mounting bracket, the clamped portion having an accommodating groove capable of accommodating the head of the fastening element, and the accommodating groove being covered by the retaining bracket.

[0015] According to this aspect, the head of the fastening element is accommodated in the accommodation groove, and the accommodation groove is covered by the retaining metal fitting, so that the fastening element is less likely to come off.

[0016] In a preferred aspect, the clamped portion has a bottom wall portion that forms the bottom of the accommodating groove, and the clamped portion is provided with a positioning portion on the bottom wall portion that engages with the mounting fixture.

[0017] According to this aspect, the position of the cover member relative to the mounting fixture can be set to a specific position.

[0018] In a preferred aspect, the clamped portion has a bottom wall portion that forms the bottom of the accommodating groove, and the clamped portion is provided with a spacing forming portion on the surface of the bottom wall portion facing the mounting bracket that forms a spacing between the bottom wall portion and the mounting bracket.

[0019] According to this aspect, by setting a predetermined distance between the bottom wall portion and the mounting fixture using the spacer, the tip of the shank of the fastening element can be prevented from coming into contact with other members.

[0020] One aspect of the present invention is a cover member that constitutes a roof structure in which a first roof member and a second roof member are arranged on a roof substrate in a stepped, overlapping manner in the eaves-ridge direction, and which has a solar cell module, a retaining bracket, and a mounting bracket, wherein the eaves side portion of the second roof member overlaps the ridge side portion of the first roof member, the retaining bracket holds the eaves side end of the solar cell module, the mounting bracket is arranged across the first roof member and the second roof member, and the retaining bracket is fixed at a position where it overlaps with the second roof member when the solar cell module is viewed in a plane, and when the roof structure is assembled, the cover member has a clamped portion that is clamped between the mounting bracket and the retaining bracket, and an extension portion that extends at an angle from the clamped portion toward the first roof member, and the eaves side end of the extension portion becomes a free end at a position close to the first roof member.

[0021] According to this aspect, the eaves-side end of the extension is close to the first roof element, so a unified appearance can be achieved between the first roof element on the eaves side and the solar cell module. As a result, there is a sense of unity between the roof element and the solar cell module, and the design is superior to conventional methods.

[0022] The above aspects may be made dependent on each other, or some of the configurations may be quoted or substituted for each other, as long as they are included in the technical scope of the present invention. [Effects of the Invention]

[0023] According to the present invention, there is a sense of unity between the roof member and the solar cell module, and the design is superior to that of the prior art. [Brief explanation of the drawings]

[0065] As shown in FIG. 10, the engagement wall portion 132 is a U-shaped portion when viewed from the side, and includes a main body wall portion 140, a connecting wall portion 141, and an opposing wall portion 142, and an engagement recess portion 143 is formed by the walls 140 to 142. The main body wall portion 140 is a plate-like extension portion that extends from the connecting wall portion 131 toward the eaves side. The connecting wall portion 141 is a wall portion that connects the eaves side end portion of the main body wall portion 140 and the eaves side end portion of the opposing wall portion 142 . The opposing wall portion 142 is a wall portion that faces the main body wall portion 140 with a gap therebetween. The engagement recess 143 is a recessed groove that opens toward the ridge side and extends in the longitudinal direction X.

[0066] (Mounting fastening element 202) The mounting fastening element 202 is a member that fixes the mounting bracket 5 and the roof component 3 to the roof underlayment 200, and specifically is a fastening element that has a head and a shaft.

[0067] (Cover fastening element 203) The cover fastening element 203 is a member that fixes the cover member 7 to the mounting bracket 5, and is a fastening element that has a head and a shaft.

[0068] (Holding fastening element 205) The holding fastening element 205 is a member that fixes the holding fitting 6 to the mounting fitting 5, and specifically, is a fastening element that has a head and a shaft.

[0069] (Fixing fastening element 206) The fixing fastening element 206 is a member that fixes the fixing member 8 to the roof underlayment 200, and specifically, is a fastening element that has a head and a shaft.

[0070] Next, the positional relationship between the components of the roof structure 1 of this embodiment will be described.

[0071] In the roof structure 1, a plurality of roof members 3 are arranged in a stepped manner on a roof substrate 200, with adjacent roof members 3, 3 in the eaves-ridge direction Y forming a step portion 150. As shown in FIG. 4, the roof component 3 has a flat portion 45 that is in surface contact with the roof underlayment 200, and an inclined portion 46 that extends from the flat portion 45 toward the eaves side. The roof member 3 has its eaves side engaging portion 31 engaging with the engaging wall portion 132 of the fixing member 8, and its ridge side engaging portion 32 engaging with the engaging wall portion 132 of the fixing member 8 adjacent to the ridge side of the fixing member 8, so that the eaves side portion and the ridge side portion are fixed to the roof underlayment 200. Therefore, the roof member 3 has its eaves side portion restricted from moving upward by the roof member 3 adjacent to the eaves side and the fixing member 8, and its ridge side portion has its upward movement restricted by the fixing member 8.

[0072] The fixing member 8 has the fixing wall portion 130 placed on the roof underlayment 200, and the shaft portion of the fixing fastening element 206 is inserted into the insertion hole 135, so that the engaging wall portion 132 is fixed in a cantilevered manner.

[0073] Focusing on the roof members 3b and 3c adjacent to each other in the eaves-ridge direction Y, the roof member 3b on the eaves side has the second opposing wall portion 38b of the ridge-side engaging portion 32b inserted into the engaging recess 143b of the fixing member 8b, as shown in Figure 4, and the ridge-side engaging portion 32b is engaged with the fixing member 8b. The ridge-side roof member 3c is engaged with the fixing member 8b and the roof member 3b adjacent to the eaves side, with the first opposing wall portion 36c of the eaves-side engagement portion 31c inserted between the opposing wall portion 142b of the fixing member 8b and the roof main body portion 30b of the eaves-side roof member 3b within the ridge-side recess 41b of the eaves-side roof member 3b.

[0074] The roof member 3b on the eaves side has the end face of the second opposing wall portion 38b covered by the connecting wall portion 141b of the fixing member 8b, and the roof member 3c on the ridge side has the first connecting wall portion 35c covering the eaves side of the connecting wall portion 141b of the fixing member 8b.

[0075] From another perspective, the ridge-side roof member 3c has the engaging wall portion 132b of the fixing member 8b and the second opposing wall portion 38b of the eaves-side roof member 3b inserted into the eaves-side recess 40c, thereby restricting the movement of the eaves-side roof member 3b and the fixing member 8b toward the eaves side.

[0076] The relationship between other adjacent roof members 3, 3 in the eaves-ridge direction Y, for example, the relationship between roof members 3a, 3b and the relationship between roof members 3c, 3d, is similar to the relationship between roof members 3b, 3c, and therefore will not be described here.

[0077] In this way, each roof component 3 is fixed to the roof underlayment 200 by each fixing component 8, and adjacent roof components 3, 3 are laid so as to engage with each other at their overlapping portions in the eaves-ridge direction Y.

[0078] The mounting bracket 5a (5b) is provided across the roof members 3a, 3b (3c, 3d) adjacent in the eaves-ridge direction Y, as shown in FIG. As shown in Figure 5, the mounting brackets 5a and 5b are placed on the roof members 3a and 3c with the fixed wall portion 50 sandwiched between the buffer portion 58, the regulating wall portion 51 contacts and presses the first connecting wall portion 35 of the roof members 3b and 3d, and the covering wall portion 52 covers the upper side of the roof main body portion 30 of the roof members 3b and 3d. The mounting fastening element 202 has its shaft inserted into the fixed side insertion hole 55 of the fixed wall portion 50 of the mounting brackets 5a and 5b and the buffer side insertion hole 59 of the buffer portion 58, and is further inserted into the roof side insertion hole 33 of the roof main body portion 30 of the roof members 3a and 3c, and is fixed to the roof underlayment 200.

[0079] The covering wall portion 52 of the mounting brackets 5a, 5b is supported in a cantilevered manner by the restricting wall portion 51, and the cable holding portion 63 constituting the ridge-side end is a free end at a position close to the roof members 3b, 3d. In other words, when the mounting brackets 5a, 5b are in a no-load state, the underside of the cable holding portion 63 does not contact the roof members 3b, 3d, leaving a slight gap. Therefore, when the mounting fastening element 202 loosens due to uplift force and the mounting bracket 5 tilts, the cable holding portion 63 can function as an abutment portion that abuts against the roof member 3.

[0080] The distance D2 between adjacent mounting brackets 5, 5 in the eaves-ridge direction Y is approximately an integral multiple of the distance D1 in the eaves-ridge direction Y between step portions 150 formed by overlapping adjacent roof members 3, 3. In this embodiment, the distance D2 between the mounting brackets 5, 5 is approximately twice the distance D1 between the stepped portions 150 in the eaves-ridge direction Y.

[0081] As shown in Figure 5, the retaining brackets 6a and 6b have their fixed wall portions 70 placed on the covering wall portions 52 of the mounting brackets 5a and 5b, and the regulating wall portion 71 and the rear side wall portion 72, together with the covering wall portions 52 of the mounting brackets 5a and 5b, form a ridge-side retaining recess 151.

[0082] As shown in Figure 5(a), the eaves side end of the solar cell module 2 is held in the eaves side holding recess 75 of the holding bracket 6a, and as shown in Figure 5(b), the ridge side end is held by the ridge side holding recess 151b composed of the holding bracket 6b and the mounting bracket 5b.

[0083] The length L1 of the solar cell module 2 in the eaves-ridge direction Y is approximately an integral multiple of the interval D1 in the eaves-ridge direction Y of the step portion 150 formed by overlapping adjacent roof members 3, 3. The length L1 of the solar cell module 2 in the eaves-ridge direction Y of this embodiment is twice the interval D1 of the step portions 150 in the eaves-ridge direction Y.

[0084] As shown in Figure 5(a), the cover member 7 is placed on the covering wall portion 52 of the first-stage mounting bracket 5a, whose clamped portion 100 is located closest to the eaves, and is covered by the back side wall portion 72 of the first-stage retaining bracket 6a, which is located closest to the eaves. Specifically, the clamped portion 100 of the cover member 7 is inserted into the ridge-side holding recess 151a formed by the first-stage mounting bracket 5a and the holding bracket 6a, and is clamped between the back side wall portion 72 of the holding bracket 6a and the covering wall portion 52 of the mounting bracket 5a.

[0085] As shown in FIG. 5(a), the legs 102 of the cover member 7 are inserted into the leg receiving portions 57 of the mounting bracket 5a, and movement toward the eaves side is restricted by the leg locking portions 56. The cover member 7 has the gap forming portions 121a and 121b positioned closer to the eaves edge than the mark portion 60 of the mounting bracket 5a.

[0086] As shown in FIGS. 4 and 5(a), the cover fastening element 203 has its shaft inserted through the cover-side insertion hole 120 and fastened to the cover fastening hole 61 of the mounting bracket 5a for fixation. The head of the cover fastening element 203 is accommodated in the accommodation recess 116 and is covered by the rear side wall portion 72 of the retaining metal fitting 6a. 5(a), the cover member 7 is supported in a cantilevered manner at the portion of the extension 101 closer to the eaves than the leg 102, and the eaves-side end of the extension 101 is a free end at a position close to the roof member 3a. In other words, when the cover member 7 is in an unloaded state, the eaves-side end of the extension 101 is not in contact with the roof member 3a, and a small gap is formed. The shortest distance between the eaves-side end of the extension 101 and the roof member 3a is preferably more than 0 mm and not more than 3 mm.

[0087] As shown in Figure 5(b), the second and subsequent mounting brackets 5b are arranged so that the buffer members 53 cover the cover fastening holes 61, and are interposed between the underside of the ridge side portion of the solar cell module 2 and the covering wall portion 52. The mounting bracket 5b has the cable portion 23a (23b) of the solar cell module 2 to be held on the eaves side attached to the mounting recess 65c of the cable holding portion 63. The cable holding portion 63 of the mounting bracket 5b allows the cable portion 23a (23b) of the solar cell module 2 to move in the longitudinal direction X when the cable portion 23a (23b) is attached to the attachment recess 65c. That is, the cable portion 23a (23b) of the solar cell module 2 can move in the longitudinal direction X while being held by the cable holding portion 63 of the mounting bracket 5b.

[0088] According to the roof structure 1 of this embodiment, in the roof members 3a, 3b adjacent in the eaves-ridge direction Y, the roof member 3a (first roof member) on the eaves side has a ridge side recess 41 that is deeper toward the ridge side, the eaves side portion of the roof member 3b (second roof member) on the ridge side overlaps with the ridge side portion of the roof member 3a on the eaves side, the roof member 3b on the ridge side has a first opposing wall portion 36 extending toward the ridge side, and the first opposing wall portion 36 is inserted into the ridge side recess 41 and engages with the roof member 3a on the eaves side, and the mounting bracket 5a is arranged across the roof member 3a on the eaves side and the roof member 3b on the ridge side, and is equipped with a restricting wall portion 51 that restricts movement of the ridge side roof member 3b in the direction opposite to the insertion direction of the first opposing wall portion 36. Therefore, the restricting wall portion 51 of the mounting bracket 5a restricts the movement of the first opposing wall portion 36 of the ridge-side roof component 3b in the separation direction, making it difficult for the ridge-side roof component 3b to separate from the eaves-side roof component 3a and difficult for the engagement between the eaves-side roof component 3a and the ridge-side roof component 3b to be released. As a result, the ridge-side roof component 3b is difficult to separate from the roof underlayment 200.

[0089] According to the roof structure 1 of this embodiment, the restricting wall portion 51 of the mounting bracket 5a faces a part of the ridge-side roof component 3b in the direction opposite to the insertion direction of the first opposing wall portion 36, at a position closer than the length in the insertion direction of the first opposing wall portion 36. Therefore, the restricting wall portion 51 prevents the first opposing wall portion 36 from slipping out of the ridge-side recess 41 and releasing the engagement between the eaves-side roof component 3a and the ridge-side roof component 3b.

[0090] According to the roof structure 1 of this embodiment, the restricting wall portion 51 of the mounting bracket 5a comes into contact with a part of the ridge-side roof component 3b and presses the ridge-side roof component 3b toward the ridge. This makes it difficult for the ridge-side roof component 3b to separate from the eaves-side roof component 3a. According to the roof structure 1 of this embodiment, the restricting wall portion 51 of the mounting bracket 5a is provided so as to come into contact with a part of the roof member 3b on the ridge side, so that the mounting bracket 5a can be easily positioned during assembly.

[0091] According to the roof structure 1 of this embodiment, the mounting bracket 5a has a fixing wall portion 50 that fixes the roof component 3a on the eaves side to the roof underlayment 200, and a covering wall portion 52 that covers the roof component 3b on the ridge side, and the fixing wall portion 50 and the covering wall portion 52 are connected in a stepped manner via a restricting wall portion 51. Therefore, the rigidity of the mounting bracket 5a can prevent the roof component 3b on the ridge side from separating upward from the roof underlayment 200.

[0092] According to the roof structure 1 of this embodiment, the ridge-side recess 41 is a recessed groove extending in the girder direction X and has a width greater than that of the first opposing wall portion 36, and the covering wall portion 52 restricts movement of the ridge-side roof member 3b in a direction intersecting with the eaves-ridge direction Y. Therefore, the first opposing wall portion 36 can be easily inserted into the ridge-side recess 41, and movement of the ridge-side roof member 3b in a direction intersecting with the eaves-ridge direction Y can be restricted.

[0093] According to the roof structure 1 of this embodiment, the solar cell module 2 has cable portions 23a, 23b that can be electrically connected to other solar cell modules 2 or external devices, and the covering wall portion 52 is provided with a cable holding portion 63 that can hold the cable portions 23a, 23b, so that the cable portion 23a (23b) can be held by the cable holding portion 63, and the cable portion 23a (23b) is less likely to get in the way when assembling the roof structure 1 or performing maintenance.

[0094] According to the roof structure 1 of this embodiment, the cable holding portion 63 accommodates a portion of the outer periphery of the cable portion 23a (23b) and allows movement of the cable portion 23a (23b) in the extension direction. Therefore, the position of the cable portion 23a (23b) is easily adjusted while restricting the movement direction of the cable portion 23a (23b) to one direction (the longitudinal direction). This makes it easy to connect the cable portion 23a (23b) to the cable portion 23b (23a) of another solar cell module 2 or to a cable of an external device.

[0095] According to the roof structure 1 of this embodiment, the length of the solar cell modules 2 in the eaves-ridge direction Y is approximately an integer multiple of the spacing between the steps 150, 150 adjacent in the eaves-ridge direction Y. Therefore, the spacing between the solar cell modules 2 in the eaves-ridge direction Y can be adjusted by the spacing between the steps 150 in the eaves-ridge direction Y.

[0096] According to the roof structure 1 of this embodiment, the mounting bracket 5b holds the ridge-side end of the solar cell module 2 on the eaves side, and includes a mounting bracket 5a (second mounting bracket) that holds the eaves-side end of the solar cell module 2 directly or via a second holding bracket, and the spacing between the mounting brackets 5a, 5b is approximately an integer multiple of the spacing between the steps 150, 150 adjacent to each other in the eaves-ridge direction Y. Therefore, the positions of the mounting brackets 5a, 5b can be adjusted by the spacing between the steps 150, 150.

[0097] According to the roof structure 1 of this embodiment, the mounting bracket 5a is arranged across the roof member 3a on the eaves side and the roof member 3b on the ridge side, and the retaining bracket 6a is fixed at a position where it overlaps with the ridge side roof member 3b when the solar cell module 2 is viewed in a plane, and the cover member 7 has a clamped portion 100 that is clamped between the mounting bracket 5a and the retaining bracket 6a, and an extension portion 101 that extends at an angle from the clamped portion 100 toward the roof member 3a on the eaves side, and the extension portion 101 has a free end at a position close to the roof member 3a on the eaves side. That is, since the eaves-side end of the extension portion 101 is close to the roof member 3a on the eaves side, an integrated appearance can be obtained between the roof member 3a on the eaves side and the solar cell module 2. As a result, there is a sense of unity between the roof member 3a on the eaves side and the solar cell module 2, and the design is superior to that of conventional methods. Furthermore, because the eaves-side end of the extension portion 101 is close to the eaves-side roofing member 3a, it is difficult for birds, animals, etc. to get between the solar cell module 2 and the ridge-side roofing member 3b through the gap between the eaves-side end of the extension portion 101 and the eaves-side roofing member 3a. In addition, wind is unlikely to get between the solar cell module 2 and the ridge-side roofing member 3b through the gap between the eaves-side end of the extension portion 101 and the eaves-side roofing member 3a, making it less likely to be subjected to loads due to wind-up forces. As a result, the solar cell module 2 is unlikely to separate from the roof underlayment 200. According to the roof structure 1 of this embodiment, the eaves side end of the extension portion 101 is a free end at a position close to the eaves side roof member 3a, so even if the cover member 7 tilts due to wind load, the eaves side end of the extension portion 101 abuts against the eaves side roof member 3a, preventing the cover member 7 from coming off.

[0098] According to the roof structure 1 of this embodiment, the shortest distance between the eaves side end of the extension portion 101 and the eaves side roof member 3a is more than 0 mm and less than 3 mm, making it more difficult for birds, animals, etc. to enter through the gap between the eaves side end of the extension portion 101 and the eaves side roof member 3a.

[0099] According to the roof structure 1 of this embodiment, the mounting bracket 5a is located closer to the eaves than the leg 102 of the cover member 7 and has a leg locking portion 56 that engages with the leg 102 in the eaves-ridge direction Y. Therefore, the leg locking portion 56 of the mounting bracket 5a can prevent the cover member 7 from moving toward the eaves, making it difficult for the cover member 7 to come off.

[0100] According to the roof structure 1 of this embodiment, the legs 102 of the cover member 7 are placed on the mounting brackets 5a, so that the roof member 3a on the eaves side can be prevented from being damaged by contact with the legs 102.

[0101] According to the roof structure 1 of this embodiment, the clamped portion 100 has an accommodating recess 116 capable of accommodating the head of the cover fastening element 203, and the accommodating recess 116 is covered by the retaining metal fitting 6a. That is, because the head of the cover fastening element 203 is accommodated in the accommodating recess 116 and the accommodating recess 116 is covered by the retaining metal fitting 6a, the cover fastening element 203 is unlikely to come off.

[0102] According to the roof structure 1 of this embodiment, the clamped portion 100 is provided with a spacer 121b that engages with the mounting bracket 5 on the bottom wall 112 that forms the bottom of the accommodating recess 116. Therefore, the position of the cover member 7 relative to the mounting bracket 5a can be set to a specific position.

[0103] According to the roof structure 1 of this embodiment, the clamped portion 100 is provided with spacing forming portions 121a, 121b that form a spacing between the bottom wall portion 112 and the mounting bracket 5a on the surface of the bottom wall portion 112 that forms the bottom of the accommodating recess 116 that faces the mounting bracket 5a. Therefore, by setting a predetermined spacing between the bottom wall portion 112 and the mounting bracket 5a using the spacing forming portions 121a, 121b, it is possible to prevent the tip of the shank of the cover fastening element 203 from coming into contact with other members.

[0104] According to the roof structure 1 of this embodiment, the mounting fastening elements 202 are inserted across the mounting brackets 5a, 5b and the roof members 3a, 3c and fastened to the roof underlayment 200, with the flat surfaces 45 of the roof members 3a, 3c in surface contact with the roof underlayment 200. In other words, since there is no gap between the roof underlayment 200 and the roof members 3a, 3c, the roof members 3a, 3c are not deformed by the load applied when fastening the mounting fastening elements 202.

[0105] In the above embodiment, the mounting recesses 65a to 65c of the cable holding part 63 are open upward, but the present invention is not limited to this. The mounting recesses 65a to 65c of the cable holding part 63 may be open in a direction other than the upward direction. For example, as shown in FIG. 11, the mounting recess 65 of the cable holding part 63 may be open on the eaves side.

[0106] In the above embodiment, the cable holding part 63 has three mounting recesses 65a to 65c, but the present invention is not limited to this. The cable holding part 63 may have one or two mounting recesses 65, or may have four or more mounting recesses 65.

[0107] In the above embodiment, the mounting recesses 65a to 65c of the cable holding part 63 have inner circumferential surfaces shaped to conform to the outer peripheries of the cable parts 23a and 23b, but the present invention is not limited to this. The mounting recesses 65a to 65c of the cable holding part 63 may have inner circumferential surfaces shaped differently from the outer peripheries of the cable parts 23a and 23b.

[0108] In the above embodiment, the mounting bracket 5a located closest to the eaves also has the cable holding portion 63, but the present invention is not limited to this. The mounting bracket 5a does not have to have the cable holding portion 63.

[0109] In the above embodiment, the mounting metal fitting 5 and the holding metal fitting 6 are separate members, but the present invention is not limited to this. The mounting metal fitting 5 and the holding metal fitting 6 may be configured as a single member.

[0110] In the above-described embodiment, the gap forming portions 121a and 121b extend in the longitudinal direction X, but the present invention is not limited to this. The gap forming portions 121 may be provided so as to surround the cover-side insertion hole 120.

[0111] In the above embodiment, the gap forming portions 121a and 121b are configured as a single member together with the bottom wall portion 112, but the present invention is not limited to this. The gap forming portions 121a and 121b may be separate members from the bottom wall portion 112.

[0112] In the above-described embodiments, each component can be freely substituted or added between the respective embodiments as long as it falls within the technical scope of the present invention. [Explanation of symbols]
