[Modes for carrying out the invention] 【0008】 The following describes each embodiment of the roof structure of this disclosure with reference to the drawings. In this embodiment, an example in which the roof structure is applied to a carport 1 will be described. In this embodiment, the carport 1 has a parking space for one or more cars below the roof body 4. In this embodiment, an example in which the roof structure is applied to a carport 1 will be described, but it is not limited to this. Furthermore, the roof structure may be applied to structures other than carports, such as bicycle parking areas, shelters, rest areas, terraces, bus stops, and so on. 【0009】 In the description of the embodiment, the direction in which the multiple roofing materials 41 constituting the roof body 4 of the carport 1 extend is also referred to as the front-rear direction Y. In the front-rear direction Y in which the multiple roofing materials 41 extend, the rear side where columns 21 and 22 of the four columns 2 are located is also referred to as the rear side Y1, and the front side where columns 23 and 24 of the four columns 2 are located is also referred to as the front side Y2. In the embodiment, the roof body 4 is sloped downwards in the front-rear direction Y, from the front side Y2 to the rear side Y1, with the front side Y2 also referred to as the upstream side and the rear side Y1 as the downstream side. The direction in which the beam 3 extends, intersecting the front-rear direction Y in which the roofing materials 41 extend, is also referred to as the left-right direction X. In the left-right direction X of the beam 3, the side where the beam 3 extends to a position away from the roof body 4 is also referred to as the X1 side, and the side where the end of the beam 3 is located near the roof body 4 is also referred to as the X2 side. Furthermore, in this embodiment, the area covered by the roof body 4 in a plan view is referred to as the "inside of the roof body 4," and the area outside the area covered by the roof body 4 in a plan view is referred to as the "outside of the roof body 4." 【0010】 First, the overall structure of the carport 1 of the first embodiment will be described. As shown in Figures 1 to 3, the carport 1 of this embodiment is a carport in which the roof body 4 is supported at the rear side Y1 in the front-rear direction Y by two columns 21 and 22, and at the front side Y2 in the front-rear direction Y, both ends of the beam 3 in the left-right direction X are supported by two columns 23 and 24. The roof body 4 of the carport 1 of this embodiment is formed to be large enough to cover the area above when one or more cars are parked there. Furthermore, the carport 1 of this embodiment is configured with a suspension structure in which the roof body 4 is suspended and connected to the lower part (below) of the beam 3, which is located near the end of the front side Y2 in the front-rear direction Y. 【0011】 As shown in Figures 1 to 3, the carport 1 of the first embodiment comprises four columns 2 erected on the ground, one beam 3, a roof body 4 positioned below the beam 3, a plurality of purlins 5 (first connecting members), and two girders 6 (second connecting members). The four columns 2 include column 21 positioned on the rear side Y1 in the front-rear direction Y and on the X2 side in the left-right direction X, column 22 positioned on the rear side Y1 in the front-rear direction Y and on the X1 side in the left-right direction X, column 23 positioned on the front side Y2 in the front-rear direction Y and on the X2 side in the left-right direction X, and column 24 positioned on the front side Y2 in the front-rear direction Y and on the X1 side in the left-right direction X. Unless otherwise specified, columns 21, 22, 23, and 24 are simply referred to as "column 2". The columns 2, beam 3, purlins 5, and girders 6 are formed, for example, from extruded aluminum profiles and have a hollow structure with a hollow cross-section. 【0012】 As shown in Figure 1, the roof body 4 is configured as a suspended structure in which the rear Y1 portion of the roof body 4 in the front-rear direction Y is supported by the upper ends of two columns 21 and 22, and the front Y2 portion of the roof body 4 in the front-rear direction Y is directly connected to the lower surface of the beam 3 and suspended from the lower part of the beam 3. 【0013】 The roof body 4 is constructed by arranging multiple roofing materials 41 in a continuous line along the left-right direction X in which the purlins 5 (described later) extend, and connecting (interlocking) them with each other. The multiple roofing materials 41 extend in the front-rear direction Y, which is the direction that intersects the direction in which the purlins 5 extend. In the front-rear direction Y in which the roofing materials 41 extend, the roof body 4 is formed with a downward slope from the front side Y2 to the rear side Y1 in the front-rear direction Y. As a result, the roof body 4 is formed with a front-rear gradient that slopes downward from the front side Y2 to the rear side Y1 in the front-rear direction Y. In this embodiment, for example, the inclination angle of the roof body 4 in the front-rear direction Y is set to about 1° to 2°. In addition, the roof body 4 is not inclined in the left-right direction X, and extends horizontally, for example. 【0014】 As shown in Figures 1 to 3, the multiple roofing materials 41 all extend in the front-to-back direction Y of the carport 1 (a direction perpendicular to the direction in which the beam 3 extends). The multiple roofing materials 41 are all formed from, for example, extruded aluminum profiles. The multiple roofing materials 41 are formed, for example, in a U-shaped frame with an open upper side and a flat (planar) lower surface. As a result, the roof body 4 is made up of multiple roofing materials 41 connected together, and as a whole, the lower surface is formed to be flat (planar). The multiple roofing materials 41 constituting the roof body 4 may be configured as a hollow structure with a hollow section, or as a solid structure with no upper surface of the hollow section and an open upper side. The upper surface of the roof body 4 may also be formed to be flat (planar). 【0015】 Multiple purlins 5 are positioned on the upper surface of the roof body 4 and connected to the upper surface of the roof body 4. The multiple purlins 5 are arranged in a line with spacing in the front-to-back direction Y. The multiple purlins 5 are formed extending in the left-to-right direction X, which is the direction in which the roofing material 41 extends, and extend in the left-to-right direction X across the multiple roofing material 41 on the upper surface of the multiple roofing material 41. In this embodiment, three purlins 5 are provided. The number of purlins 5 is not limited. 【0016】 Multiple purlins 5 connect multiple roofing materials 41 that make up the roof body 4. Each of the multiple purlins 5 is fixed to each of the multiple roofing materials 41 by fastening members such as screws. Because multiple purlins 5 connect and fix multiple roofing materials 41, the strength of the roof body 4 can be improved. 【0017】 The two girders 6 are positioned above the roof body 4 at positions outside the left-right direction X of the roof body 4, and are located on the upper surface of the roof body 4. The two girders 6 each extend in the front-rear direction Y, which intersects the direction in which the beams 3 and purlins 5 extend. 【0018】 The two girders 6 are respectively arranged outside the end portions on the X1 side and the X2 side in the left - right direction X of the plurality of purlins 5 on the upper surface of the roof body main body 4. On the inner side surfaces in the left - right direction X of the two girders 6, the longitudinal end portions (end portions on the Y2 side in the front - rear direction Y) of the plurality of purlins 5 are respectively arranged opposite to each other. The longitudinal end portions of the plurality of purlins 5 are connected and joined to the inner side surfaces in the left - right direction X of the girder 6. 【0019】 Both of the two girders 6 have their lower surfaces fixed to the upper surface of the roof body main body 4, and the end portions on the front side Y2 in the front - rear direction Y are arranged on the side of the rear side Y1 in the front - rear direction Y of the beam 3 and are connected to the side surface of the rear side Y1 in the front - rear direction Y of the beam 3. The two girders 6 may be directly connected to the beam 3 or may be connected to the beam 3 via a connecting member (not shown). By connecting the two girders 6 to connect the plurality of purlins 5 that connect the plurality of roof materials 41, the strength can be reinforced so that the roof materials 41 of the roof body main body 4 do not bend, and the strength of the roof body main body 4 can be improved. 【0020】 Of the four columns 2, the two columns 21 and 22 arranged on the rear side Y1 in the front - rear direction Y of the roof body main body 4 are arranged near the inside of the corner portion on the rear side Y1 in the front - rear direction Y of the roof body main body 4 as shown in FIGS. 1 and 3. 【0021】 The two columns 21 and 22 are arranged apart from each other in the left - right direction X at the end portion side on the rear side Y1 in the front - rear direction Y of the carport 1. The two columns 21 and 22 respectively extend in the up - down direction. The two columns 21 and 22 penetrate the roof body main body 4 in the up - down direction at the end portion side on the rear side Y1 in the front - rear direction Y of the carport 1 as shown in FIG. 3. The upper end portions of the two columns 21 and 22 are both connected to the lower surface of the girder 6 arranged on the upper surface of the roof body main body 4 above the roof body main body 4. 【0022】 As a result, the two columns 21 and 22 positioned at the rear end Y1 of the carport 1 penetrate the roof body 4 vertically and are connected to the underside of the rear end Y1 of the beam 6, thereby supporting the rear end Y1 of the beam 6 from below. Thus, the rear Y1 portion of the roof body 4 is supported by the upper ends of the two columns 21 and 22 via the beam 6. 【0023】 Of the four columns 2, the two columns 23 and 24, which are located on the front side Y2 in the front-to-back direction Y of the roof body 4, are positioned on the outside in the left-to-right direction X of the roof body 4, on the front side Y2 in the front-to-back direction Y of the roof body 4, as shown in Figures 1 and 3. 【0024】 As shown in Figures 1 and 3, the two columns 23 and 24 are positioned at a distance in the left-right direction X, near the front end Y2 of the carport 1 in the front-rear direction Y, and are located outside the roof body 4 in the left-right direction X. The two columns 23 and 24 each extend in the vertical direction. The beam 3 is connected to the upper ends of the two columns 23 and 24. 【0025】 In this embodiment, column 23, one of the two columns 23 and 24, is positioned on the outside of the X2 side in the left-right direction X, on the outside of the X2 side of the roof body 4, and is positioned close to the side of the roof body 4. Column 24, one of the two columns 23 and 24, is positioned on the outside of the X1 side in the left-right direction X, on the outside of the X1 side of the roof body 4, and is positioned away from the side of the roof body 4. Column 24 is positioned away from the side of the roof body 4 by a distance, for example, at least the width of one roofing material 41 in the left-right direction X, on the outside of the X1 side in the left-right direction X. In this embodiment, in the left-right direction X, "position away from the roof body 4" means that column 24 is positioned so as not to overlap with the roof body 4 at all in the vertical direction. 【0026】 As shown in Figures 1 to 3, the two columns 23 and 24 are positioned near the front end Y2 in the front-to-back direction Y of the roof body 4, and are located on the outer sides of both ends in the left-to-right direction X of the roof body 4. The positions of the columns 23 and 24 in the left-to-right direction X (the direction in which the beam 3 extends) can be set to any position depending on the surrounding conditions. This allows the columns 23 and 24 to be set to any position in the left-to-right direction X from which the beam 3 extends. 【0027】 As shown in Figures 1 and 3, beam 3 is positioned above the roof body 4 and on the upper surface of the roof body 4. As shown in Figure 1, beam 3 is formed extending in the left-right direction X. Both ends of beam 3 in the longitudinal direction are connected to the upper ends of two columns 23 and 24. Beam 3 extends in the left-right direction X for a length that connects the upper ends of two columns 23 and 24, which are positioned near the front end Y2 in the front-back direction Y of the roof body 4. The lower surface of the lower part of beam 3 is connected to the roof body 4. 【0028】 The beam 3, which is connected to the column 23 on the X2 side in the left-right direction X, extends longitudinally from the upper surface of the roof body 4 to the column 23 located near the outside of the roof body 4 on the X2 side in the left-right direction X, with the portion of the beam 3 on the column 23 side extending outwards on the X2 side in the left-right direction X. 【0029】 The beam 3, which is connected to the column 24 on the X1 side in the left-right direction X, extends longitudinally from the upper surface of the roof body 4 to the column 24, which is located at a distance from the roof body 4 to the X1 side of the roof body 4, with the portion of the beam 3 on the column 24 side extending outwards on the X1 side in the left-right direction X. 【0030】 The embodiment described above provides the following effects. The carport 1 of this embodiment comprises a plurality of columns 2, a beam 3 connected to at least one of the plurality of columns 23, 24, a roof body 4 having a plurality of long roofing materials 41 directly or indirectly connected to the beam 3, a plurality of purlins 5 formed extending in a direction intersecting the direction in which the roofing materials 41 extend and connecting the plurality of roofing materials 41, and a girder 6 formed extending in a direction intersecting the direction in which the purlins 5 extend and connecting the plurality of purlins 5, wherein the columns 2 connected to the beam 3 are arranged on the outside of the roof body 4. 【0031】 This ensures the strength of the roof body 4 by connecting multiple roofing materials 41 with multiple purlins 5, and also ensures the strength of the roof body 4 by connecting multiple purlins 5 with girders 6 to prevent bending. Furthermore, since the columns 23 and 24 are positioned outside the left-right direction X of the roof body 4, the degree of freedom in the placement of the columns 23 and 24 is increased. Thus, in a carport 1 (roof structure) equipped with purlins 5 and girders 6, the strength of the roof body 4 can be ensured while flexibly determining the positions of the columns 23 and 24 to accommodate the size and shape of the site. 【0032】 Furthermore, in this embodiment, the multiple roofing materials 41 are arranged in a continuous line and connected in the direction in which the purlin 5 extends. Since the multiple roofing materials 41 are connected to each other and each of the multiple roofing materials 41 can be connected at the purlin 5, the strength of the roof body 4 can be further improved. 【0033】 Furthermore, in this embodiment, multiple purlins 5 are connected to the sides of the beams 6. As a result, by connecting multiple purlins 5 to the sides of the beams 6, the strength is reinforced, and the purlins 5 and beams 6 are not offset in the height direction of the roof body 4. This prevents the purlins 5 and beams 6 from protruding in the height direction of the roof body 4, thereby improving the design and aesthetic appeal. 【0034】 Furthermore, in this embodiment, the beam 3 is positioned above the roof body 4 and extends in a direction intersecting the direction in which the girder 6 extends. The girder 6 is positioned above the roof body 4, and the beam 3 is connected to the girder 6. As a result, the beam 3 is connected to the girder 6, which further improves the strength of the roof body 4. 【0035】 Furthermore, in this embodiment, the girder 6 is positioned to the side of the beam 3 and connected to the side of the beam 3. As a result, by connecting the girder 6 to the side of the beam 3, the strength is reinforced, and the girder 6 and beam 3 are not positioned offset in the height direction of the roof body 4, thereby preventing the girder 6 and beam 3 from protruding in the height direction of the roof body 4, thus improving the design and aesthetic appeal. 【0036】 Furthermore, in this embodiment, the column 24 connected to the beam 3 is positioned outside the roof body 4 at a distance from the roof body 4, and the beam 3 connected to the column 2 extends longitudinally from the roof body 4 to the column 24 positioned at a distance from the roof body 4. As a result, the column 24 is positioned outside the roof body 4 in the left-right direction X, which improves the degree of freedom in the position where the column 24 is installed. In addition, by extending the beam 3 connected to the column 2 longitudinally to the column 24 positioned at a distance from the roof body 4, functional members (such as delivery boxes, mailboxes, and decorative building materials) can be placed on the underside of the extended beam 3. 【0037】 Furthermore, in this embodiment, the lower surface of the roof body 4 is formed to be flat. As a result, when the roof body 4 is viewed from below, the lower surface of the roof body 4 appears flat, thus improving its aesthetic appeal. 【0038】 Furthermore, in this embodiment, the roof body 4 is positioned below the beam 3 and is suspended from the beam 3 in a suspended structure. This makes it difficult to see the beam 3 from below the roof body 4, thus improving the aesthetic appearance. 【0039】 Furthermore, in this embodiment, columns 21 and 22, which are among the multiple columns 2 and are not connected to beam 3, are connected to girders 6 that are positioned above the roof body 4 and penetrate it vertically. As a result, since columns 21 and 22 are positioned to penetrate the roof body 4, they are not positioned outside the roof body 4 but within the area where the roof body 4 is positioned, thereby improving the design. 【0040】 [Second Embodiment] Next, a second embodiment will be described. Configurations not described in the second embodiment can be described by referring to the description of the first embodiment. 【0041】 As shown in Figure 4, the carport 1A (roof structure) of the second embodiment mainly consists of the configuration of the carport 1 (roof structure) of the first embodiment shown in Figure 1, plus two girders 6A formed by extending the two girders 6 of the first embodiment to the front side Y2 in the front-rear direction Y, and one purlin 5A arranged in line with the front side Y2 in the front-rear direction Y of the multiple purlins 5, and a beam 3A that extends over the upper ends of the two girders 6A and is supported at both ends by columns 23A and 24A. 【0042】 As shown in Figures 4 to 6, the carport 1A of the second embodiment comprises four columns 2 erected on the ground, one beam 3A, a roof body 4 positioned below the beam 3A, four (or more) purlins 5, 5A (first connecting members), and two girders 6A (second connecting members). 【0043】 The configuration of the two columns 21 and 22 located at the rear Y1 in the front-rear direction Y of the four columns 2 is the same as in the first embodiment. The two columns 23A and 24A located at the rear Y1 in the front-rear direction Y of the four columns 2 are positioned in the same location as the two columns 23 and 24 in the first embodiment, and extend upward with a longer length than the two columns 23 and 24 in the first embodiment. 【0044】 The multiple purlins 5, 5A include, in addition to the three (multiple) purlins 5 of the first embodiment, one purlin 5A arranged in line with the three purlins 5 on the front side Y2 in the front-rear direction Y. The purlin 5A is positioned on the upper surface of the roof body 4 on the front side Y2 in the front-rear direction Y, and extends in the left-right direction X, similar to the multiple purlins 5. 【0045】 The two girders 6A are constructed by extending the two girders 6 of the first embodiment to the front side Y2 in the longitudinal direction Y. Similar to the first embodiment, the longitudinal ends of multiple purlins 5, 5A are connected to the inner sides of the two girders 6A in the left-right direction X. 【0046】 Beam 3A is positioned extending in the left-right direction X across the upper ends of the two girders 6A. Both longitudinal ends of beam 3A are connected to the upper ends of columns 23A and 24A and supported by the upper ends of columns 23A and 24A. Beam 3A is positioned above the two girders 6A, on the upper surfaces of the two girders 6A, and connected to the upper surfaces of the two girders 6A. As a result, the two girders 6A are positioned below beam 3A and connected to the lower surfaces of beam 3A. 【0047】 Here, the beam 3A of the second embodiment shown in Figure 6 is positioned higher than the beam 3 of the first embodiment shown in Figure 3. Therefore, comparing the position of the beam 3 of the first embodiment shown in Figure 3 with the position of the beam 3A of the second embodiment shown in Figure 6, the beam 3 of the first embodiment shown in Figure 3 is positioned lower in the vertical direction of the roof body 4 than the beam 3A of the second embodiment shown in Figure 6. Thus, the beam 3 of the roof structure 1 of the first embodiment shown in Figure 3 does not protrude in the height direction of the roof body 4 compared to the beam 3A of the roof structure 1A of the second embodiment shown in Figure 6, thus improving the design and aesthetic appeal. 【0048】 According to the second embodiment, similar to the first embodiment, the columns 23A and 24A are positioned outside the left-right direction X of the roof body 4. Therefore, in a carport 1A (roof structure) equipped with purlins 5, 5A and beams 6A, the positions of the columns 23A and 24A can be flexibly determined in accordance with the size and shape of the site while ensuring the strength of the roof body 4. 【0049】 [Third Embodiment] Next, a third embodiment will be described. Configurations not described in the third embodiment can be described by referring to the description of the first embodiment. 【0050】 As shown in Figure 7, the carport 1B (roof structure) of the third embodiment is mainly a configuration of the carport 1 (roof structure) of the first embodiment shown in Figure 1, in which column 23B is provided at an inner position in the left-right direction X of the roof body 4, instead of column 23, which is located on the outer side of the left-right direction X2 of the two columns 23, 24 that are located on the front side Y2 in the front-rear direction Y of the roof body 4 of the first embodiment. 【0051】 As shown in Figure 7, the carport 1B of the third embodiment comprises four columns 2 erected on the ground, one beam 3B, a roof body 4 positioned below the beam 3B, three (or more) purlins 5 (first connecting members), and two girders 6, 6B (second connecting members). 【0052】 The configuration of the two columns 21 and 22 positioned at the rear Y1 in the front-rear direction Y of the four columns 2 is the same as in the first embodiment. 【0053】 Of the four columns 2, the two columns 23B and 24, which are positioned on the front Y2 side in the front-to-back direction Y of the roof body 4, are located at a distance in the left-to-right direction X near the end of the front Y2 side in the front-to-back direction Y of the carport 1. The two columns 23B and 24 extend in the vertical direction. 【0054】 The column 24 positioned on the X1 side in the left-right direction X is located on the outside of the roof body 4 on the X1 side in the left-right direction X. The upper end of the column 24 positioned on the X1 side in the left-right direction X is connected to the X1 end of the beam 3 on the X1 side in the left-right direction X. 【0055】 Column 23B, located on the X2 side in the left-right direction X, is positioned near the X2 end of the roof body 4 in the left-right direction X, and near the front Y2 end of the roof body 4 in the front-rear direction Y. As a result, in a plan view, column 23B is positioned inside the roof body 4. Column 23B, located on the X2 side in the left-right direction X, is positioned to penetrate the roof body 4 vertically, similar to the two columns 21 and 22 located at the rear Y1 end of the front-rear direction Y. The upper end of column 23B is connected to the underside of girder 6B, which is positioned on the upper surface of the roof body 4 above the roof body 4. Column 23B is not connected to beam 3B, but is connected to the underside of girder 6B. 【0056】 Regarding the connection between the roof body 4 and the column 23B, in addition to connecting the upper end of the column 23B to the underside of the girder 6B by passing it through the roof body 4, the upper end of the column 23B and the girder 6B located on the upper surface of the roof body 4 may also be connected by using a connecting member (not shown) that protrudes downward from the underside of the girder 6B located on the upper surface of the roof body 4, and fixing the connecting member protruding downward from the underside of the girder 6B to the upper end of the column 23B. 【0057】 The two girders 6 and 6B are positioned above the roof body 4 at an external position in the left-right direction X of the roof body 4, and are located on the upper surface of the roof body 4. The two girders 6 and 6B each extend in the front-rear direction Y, which intersects the direction in which the beams 3B and purlins 5 extend. The two girders 6 and 6B are connected to the upper surface of the roof body 4. The two girders 6 and 6B may be integrally formed with the upper surface of the roof body 4, or they may be connected to the upper surface of the roof body 4 via connecting fittings (not shown). 【0058】 Of the two girders 6 and 6B, girder 6B, positioned on the left-right X2 side, is constructed by extending girder 6, positioned on the left-right X2 side of the two girders 6 in the first embodiment shown in Figure 1, to the front Y2 side in the front-rear Y direction. Similar to the first embodiment, the longitudinal ends of multiple purlins 5 are connected to the inner sides of the two girders 6 and 6B in the left-right X direction. 【0059】 Beam 3B is positioned above the roof body 4 and on the upper surface of the roof body 4. Beam 3B is formed extending in the left-right direction X. The end of beam 3B on the X2 side in the left-right direction X is formed to be shorter than the end of beam 3 on the X2 side in the left-right direction X in the first embodiment. 【0060】 The end of beam 3B on the X1 side in the longitudinal direction of the left-right direction X is connected to the upper end of column 24. Similar to the first embodiment, beam 3B connected to column 24 on the X1 side in the left-right direction X extends longitudinally from the upper surface of the roof body 4 to column 24 which is located away from the roof body 4 on the X1 side in the left-right direction X, and the portion of beam 3B on the column 24 side extends outward on the X1 side in the left-right direction X. 【0061】 The end face of the beam 3B on the X2 side in the longitudinal direction X is connected to the side of the girder 6B on the X1 side in the longitudinal direction X. The roof body 4 is connected to the lower surface of the lower part of beam 3B. 【0062】 According to the third embodiment, the column 23B, which is located on the X2 side in the left-right direction X, is positioned near the end of the roof body 4 on the X2 side in the left-right direction X, and near the end of the front Y2 side in the front-rear direction Y of the roof body 4. Therefore, by positioning the column 23B on the X2 side in the left-right direction X, which is opposite to where the beam 3B is extended, in a plan view, the column 23B is not positioned on the outside of the X2 side in the left-right direction X of the roof body 4. This configuration allows the roof body 4 to be positioned close to the property boundary, which is the boundary with the adjacent land owned by another person, on the X2 side in the left-right direction X of the carport 1B. Furthermore, because the roof body 4 can be provided close to the property boundary, which is the boundary with the adjacent land owned by another person, it is possible to move around without getting wet in the rain at a location close to the property boundary. 【0063】 [Fourth Embodiment] Next, a fourth embodiment will be described. Configurations not described in the fourth embodiment can be described by referring to the description of the first embodiment. 【0064】 As shown in Figure 8, the carport 1C (roof structure) of the fourth embodiment is mainly a configuration of the carport 1 (roof structure) of the first embodiment shown in Figure 1, in which column 23C is provided at an inner position in the left-right direction X of the roof body 4, instead of column 23, which is located on the outer side of the left-right direction X2 of the two columns 23, 24 that are located on the front side Y2 in the front-rear direction Y of the roof body 4 of the first embodiment. 【0065】 As shown in Figure 8, the carport 1B of the third embodiment comprises four columns 2 erected on the ground, one beam 3C, a roof body 4 positioned below the beam 3B, three (or more) purlins 5 (first connecting members), and two girders 6 (second connecting members). 【0066】 The configuration of the two columns 21 and 22 positioned at the rear Y1 in the front-rear direction Y of the four columns 2 is the same as in the first embodiment. The configuration of the two girders 6 is the same as in the first embodiment. 【0067】 Of the four columns 2, the two columns 23C and 24, which are positioned on the front Y2 side in the front-to-back direction Y of the roof body 4, are positioned at a distance in the left-to-right direction X near the end of the front Y2 side in the front-to-back direction Y of the carport 1. The two columns 23C and 24 extend in the vertical direction. 【0068】 The column 24 positioned on the X1 side in the left-right direction X is located on the outside of the roof body 4 on the X1 side in the left-right direction X. The upper end of the column 24 positioned on the X1 side in the left-right direction X is connected to the X1 end of the beam 3C on the X1 side in the left-right direction X. 【0069】 Column 23C, positioned on the X2 side in the left-right direction X, is located near the X2 end of the roof body 4 in the left-right direction X, and near the front Y2 end of the roof body 4 in the front-back direction Y. As a result, in a plan view, column 23C is located on the inside of the roof body 4. Column 23C, positioned on the X2 side in the left-right direction X, penetrates the roof body 4 vertically. The upper end of column 23C is connected to the lower surface of beam 3C, which is located on the upper surface of the roof body 4 above the roof body 4. Column 23C is a different column from column 24, which is one of the two columns 23C, 24 connected to beam 3C and is located on the outside of the roof body 4. 【0070】 Regarding the connection between the roof body 4 and the column 23C, in addition to connecting the upper end of the column 23C to the lower surface of the beam 3C by passing it through the roof body 4, the upper end of the column 23C and the beam 3C located on the upper surface of the roof body 4 may also be connected by using a connecting member (not shown) that protrudes downward from the lower surface of the beam 3C located on the upper surface of the roof body 4, and fixing the connecting member protruding downward from the lower surface of the beam 3C to the upper end of the column 23C. 【0071】 Beam 3C is positioned above the roof body 4 and on the upper surface of the roof body 4. Beam 3C is formed extending in the left-right direction X. The end of beam 3C on the X2 side in the left-right direction X is formed to be shorter than the end of beam 3 on the X2 side in the left-right direction X in the first embodiment. 【0072】 The end of the beam 3C on the X1 side in the left-right direction X in the longitudinal direction is connected to the upper end of the column 24. The beam 3C connected to the column 24 on the X1 side in the left-right direction X extends longitudinally from the upper surface of the roof body 4 to the column 24 which is located away from the roof body 4 on the X1 side in the left-right direction X, similar to the first embodiment, and the portion of the beam 3C on the column 24 side extends outward on the X1 side in the left-right direction X. 【0073】 The end of beam 3C on the X2 side in the longitudinal direction X does not protrude X2 from the X2 side end of the roof body 4 in the longitudinal direction, but is positioned on the upper surface of the roof body 4, on the inside of the roof body 4. The end of beam 3C on the X2 side in the longitudinal direction X is formed to be shorter than the end of beam 3 on the X2 side in the longitudinal direction X in the first embodiment. In this embodiment, the end of beam 3C on the X2 side in the longitudinal direction X is formed at the same position as the X2 side end of the roof body 4 in the longitudinal direction X. The roof body 4 is connected to the lower surface of the lower part of beam 3C. 【0074】 According to the fourth embodiment, the column 23C, which is located on the X2 side in the left-right direction X, is positioned near the end of the roof body 4 on the X2 side in the left-right direction X, and near the end of the front Y2 side in the front-rear direction Y of the roof body 4. Therefore, by positioning the column 23C on the X2 side in the left-right direction X, which is opposite to where the beam 3C is extended, in a plan view, the column 23C is not positioned on the outside of the X2 side in the left-right direction X of the roof body 4. This configuration allows the roof body 4 to be positioned close to the property boundary, which is the boundary with the adjacent land owned by another person, on the X2 side in the left-right direction X of the carport 1B. Furthermore, because the roof body 4 can be provided close to the property boundary, which is the boundary with the adjacent land owned by another person, it is possible to move around without getting wet in the rain at a location close to the property boundary. 【0075】 Although a preferred embodiment of the roof structure of this disclosure has been described above, this disclosure is not limited to the embodiment described above and can be modified as appropriate. 【0076】 For example, in the above embodiment, the structure was configured with four columns 2, but the number of columns is not limited to this number. 【0077】 Furthermore, it is sufficient that at least one of the multiple columns 2 is connected to a beam, and other columns not connected to the beam may be connected to the beam, or they may not be connected to the beam but instead connected to the underside of a girder or the roof body. For example, in the above embodiment, columns 23 and 24 are connected to both ends of the beams 3 and 3A in the longitudinal direction, but the embodiment is not limited to this, and columns may be connected to either one end of the beams 3 and 3A in the longitudinal direction, and other columns may be connected to the underside of a girder or the roof body on the other end of the beams 3 and 3A in the longitudinal direction. 【0078】 Furthermore, although the above embodiment uses a configuration with one beam 3,3A, it is not limited to this. A configuration with multiple beams is also possible. When multiple beams are provided, columns located on the outside of the roof body 4 may be connected to both ends or one end of each beam in the longitudinal direction. 【0079】 Furthermore, although the above embodiment describes a configuration in which both ends of the beams 3 and 3A in the longitudinal direction are extended in the longitudinal direction, the embodiment is not limited to this. The configuration may also describe a configuration in which only one end of the beams 3 and 3A in the longitudinal direction is extended in the longitudinal direction. In addition, the configuration may describe a configuration in which both ends or one end of the beams 3 and 3A in the longitudinal direction are extended to be longer or shorter than in the above embodiment. 【0080】 Furthermore, in the above embodiment, the roof body 4 is directly connected (fixed) to the beam 3 below the beam 3, but the invention is not limited to this, and the roof body 4 may be indirectly connected (fixed) to the beam 3 via other members. 【0081】 Furthermore, in the above embodiment, the roof body 4 is configured to be suspended from the beam 3, but it is not limited to this configuration, and may also be configured to be placed above the beam 3. 【0082】 Furthermore, in the first and second embodiments, the roof body 4 is configured to be inclined in the front-rear direction Y, but the invention is not limited to this, and the roof body 4 may also be configured to be inclined in the left-right direction X. 【0083】 Furthermore, in the first and second embodiments, beams 3 and 3A are connected to columns 23, 23A, 24, and 24A, but the invention is not limited to this configuration, and the ends of the beams may be connected to the sides of the columns. 【0084】 Furthermore, in the first and second embodiments, the purlins 5, 5A (first connecting members) are directly connected (fixed) to the roof body 4. However, the invention is not limited to this, and the purlins 5, 5A (first connecting members) may be indirectly connected (fixed) to the roof body 4 via other members.
