The upper first fin piece 178a and the upper second fin piece 178a. 178b, an upper third fin piece 178c and an upper fourth fin piece 178d. The upper first fin piece 178a extends substantially horizontally toward the front from the upper edge 175a of a portion of the upper wall portion 175 which is bent upward at a substantially right angle, and is slightly convex downward. So curved. The upper second fin piece 178b is inclined and extended so as to be gradually upward from the front edge of the upper first fin piece 178a toward the front. The upper third fin piece 178c is bent from the upper edge of the upper second fin piece 178b, and is inclined and extended so as to be gradually upward toward the rear. The upper third fin piece 178c is configured such that the position of the trailing edge is forward of the upper edge of the upper support wall portion 174 and is higher than the upper edge of the upper support wall portion 174. The upper fourth fin piece 178d is bent from the edge portion of the upper third fin piece 178c toward the upper side at a substantially right angle. That is, the upper fin portion 178 having the upper first fin piece 178a, the upper second fin piece 178b, the upper third fin piece 178c, and the upper fourth fin piece 178d is located between the upper support wall portion 174 and above. A panel mounting portion 17A that opens rearward is configured.

  As is clear from the figure, the upper fin 178 is provided with drainage holes 178e at a plurality of positions along the length of the front frame 17. As shown in FIG. 2, the drain hole 178e has a long hole shape along the longitudinal direction of the front frame 17, and opens downward, and is the lowest in the upper fin 178. It is formed on the fin piece 178a. In the present embodiment, drainage holes 178e are formed at four positions between the rafters 19 and the rafters 26 and between the rafters 26, respectively.

  The rear wall portion 173 of the front frame base portion 170 is provided with a lower support wall portion 173a at the upper edge portion. The lower support wall portion 173a is a portion on which the rafter base portion 26a of the rafter 26 and the rafter base portion 19a of the wife rafter 19 are placed, and the lower support wall portion 173a is gradually inclined upward from the upper edge portion of the rear wall portion 173 toward the rear. It has been extended. When the upper cover portion 26b of the rafter 26 and the upper cover portion 19b of the wife rafter 19 are placed on the lower support wall portion 173a, the upper cover portion 26b of the rafter 26 and the upper cover portion 19b of the wife rafter 19 are placed. The respective dimensions are set so that can contact the upper fourth fin piece 178d of the upper fin portion 178.

  Further, the upper support wall portion 174 is provided with a groove-shaped attachment portion 174a at a site extending along the entire length of the front frame 17. The groove-shaped mounting portion 174a has a dovetail groove shape that is open toward the front and has a larger internal dimension with respect to the opening width. The windshield member 50 is attached to the groove-shaped attachment portion 174a at a site extending over the entire length of the front frame 17. The windshield member 50 is an extruded shape member formed of a metal such as an aluminum alloy, and has a uniform cross section over the entire length. In the present embodiment, the windshield member 50 in which the flat plate-shaped substrate portion 50a and the insertion plate portion 50b provided at one edge of the substrate portion 50a are integrally molded is applied. In this windshield member 50, the insertion plate portion 50b is arranged in the groove-shaped mounting portion 174a, and is attached to the upper support wall portion 174 in a state where the substrate portion 50a projects from the opening of the groove-shaped mounting portion 174a.

  As is clear from the figure, the base plate portion 50a of the windshield member 50 secures a gap between the upper first fin piece 178a and the upper second fin piece 178b of the upper fin portion 178, and the upper first fin piece 178b. The opening of the water draining hole 178e provided in 178a is projected so as to be gradually downward toward the front inside the panel mounting portion 17A while covering the upper region thereof. That is, the windshield member 50 is interposed on the path connecting the joint between the upper support wall portion 174 of the front frame 17 and the upper cover portion 26b of the rafter 26 (hereinafter referred to as the first joint portion C1) from the water drain hole 178e. In addition, the water is interposed between the upper support wall portion 174 of the front frame 17 and the upper cover portion 19b of the roof rafter 19 (hereinafter referred to as the second joint portion C2) from the water drain hole 178e, It is arranged so as to interfere with the path from the hole 178e directly to the first joint C1 or the second joint C2.

  In the outdoor structure 10 having the above-described configuration, as shown in FIG. 1B, after attaching the wife rafters 19 to the frame vertical frame 11 and the rafter rack 13 attached to the outer wall W of the building, the wife A front frame 17 is provided between the rafters 19, a rafter 26 is provided between the front frame 17 and the rafter rack 13, and a roof panel 20 is attached to the roof opening 24 to form a roof structure. The lower edge portion of the roof panel 20 is inserted into the above-mentioned front frame 17 together with the upper cover portion 26b of the rafter 26 and the upper cover portion 19b of the wife rafter 19 with respect to the panel mounting portion 17A. In this state, the sealing member 20a attached to the upper support wall portion 174 is in contact with the lower surface of the roof panel 20, and the lower surface of the upper third fin piece 178c is in contact with the upper surface. Regarding the rafters 26 and the wife rafters 19, the tips of the upper cover portions 26b and 19b abut the upper fourth fin pieces 178d, and the lower surfaces of the upper cover portions 26b and 19b abut the upper edges of the upper support wall portions 174. It becomes a state. Further, end caps 60 are attached to both front end surfaces of the front frame 17 so as to close both ends of the panel mounting portion 17A and both ends of the gutter portion 179. A drainage path is connected to the gutter portion 179 of the front frame 17 at one end by a water collector 180 and a vertical gutter 181.

  According to the outdoor structure 10 including this roof structure, since the upper area of the terrace 1 is covered with the roof panel 20, rainwater does not drip into the room even during rainfall. That is, the rainwater dropped on the roof structure is guided to the front side through the roof panel 20, the rafters 26, and the rafters 19, and is received by the gutter portion 179 of the front frame 17. Will be discharged to the ground. Therefore, the convenience of the outdoor structure 10 is improved such that the laundry can be dried even when it is raining.

  Here, part of the rainwater that has traveled through the roof panel 20, the rafters 26, and the rafters 19 may enter the panel mounting portion 17A through the gap with the front frame 17. That is, since the upper cover portions 26b and 19b of the rafters 26 and the wife rafters 19 and the upper fourth fin piece 178d of the front frame 17 are configured to be directly joined to each other by metal, rainwater may leak from the mutual gaps to the panel mounting portion 17A. There is a risk of infiltration. Further, since the lower edge portion of the roof panel 20 is inserted into the panel mounting portion 17A, there is a possibility that rainwater that has traveled along the upper surface may enter the panel mounting portion 17A.

  However, in this roof structure, a drain hole 178e is provided in the upper first fin piece 178a which is the bottom of the panel mounting portion 17A. Therefore, the rainwater that has entered the panel mounting portion 17A is discharged to the outside through the drain hole 178e. The rainwater discharged from the drainage hole 178e to the outside of the panel mounting portion 17A is received by the upper wall portion 175 of the front frame 17 and guided to the trough portion 179 as it is, so that the drainage route eventually leads to the ground outside the terrace 1. There is no risk of it being discharged into the room and entering the room.

  Furthermore, in the above-mentioned roof structure, the windshield member 50 is provided so as to project inside the panel mounting portion 17A. Therefore, even if the outdoor air enters the inside of the panel mounting portion 17A through the water drain hole 178e under the condition that the wind is blowing, the windshield member 50 hinders the progress thereof and the entered air is exposed to the outside. It is not directly discharged from the gap leading to. More specifically, the air that has entered the inside of the panel mounting portion 17A from the water drain hole 178e comes into contact with the base plate portion 50a of the windshield member 50, or advances while bypassing the base plate portion 50a, so that there is momentum. It will be weakened and will not be discharged to the outside of the panel mounting portion 17A through the first joint portion C1 and the second joint portion C2 with the invading momentum. As a result, even if the rainwater that has entered the inside of the panel mounting portion 17A remains without being discharged through the water draining hole 178e, it may be discharged outside together with the air that has entered through the water draining hole 178e. It is possible to prevent water leakage into the room.

  Moreover, in the front frame 17 applied to the above-described roof structure, the extending edge portion 177a of the front fin portion 177 has substantially the same height as the upper edge 175a of the upper wall portion 175 which is bent upward at a substantially right angle. It is configured to be Therefore, the outside air does not directly enter the water draining hole 178e, in other words, only the air that advances while circumventing the front fin portion 177 enters the water draining hole 178e. Therefore, it is possible to prevent the air itself from entering through the water drain hole 178e, which causes water leakage. As a result, according to the roof structure described above, it is possible to more reliably prevent water leakage into the room.

  In addition, in the above-described embodiment, the drain hole 178e is formed so as to open downward to make it difficult for air to enter the inside of the panel mounting portion 17A, but the present invention is not limited to this. For example, as in the modified example 1 shown in FIG. 6, an upper fin portion 278 having an upper first fin piece 278a that gradually increases upward from the upper wall portion 175 is formed, and the upper fin fin 278 is formed. It is also possible to form the drain hole 278b in the piece 278a. In this modified example 1, since the draining hole 278b is provided in the upper first fin piece 278a that is inclined, air is more likely to enter the inside of the panel mounting portion 17A from the draining hole 278b as compared with the embodiment. Become. However, since the windshield member 50 is provided inside the panel mounting portion 17A and the progress of the air that has entered the inside is obstructed, there is no risk of leakage into the room. In addition, in the modification 1, the same components as those in the embodiment are designated by the same reference numerals.

  Further, although the windshield member 50 is provided separately from the front frame 17 in the above-described embodiment and modification 1, the windshield member 50 may be provided integrally with the front frame 17. In addition, when the windshield member 50 is provided separately from the front frame 17, in the above-described embodiment and the first modification, the windshield member 50 is formed of the same metal as that of the front frame, but the present invention is not necessarily limited to this. A material made of other material may be applied as long as it obstructs the progress of the air. For example, in the modification 2 shown in FIG. 7, the windshield member 250 is made of a sponge that is a porous soft material, and is arranged so as to project inside the panel mounting portion 17A. The conditions for disposing the windshield member 250 are the same as those in the embodiment. In the illustrated example, the windshield member 250 is formed so as to have a larger plate thickness than the windshield member 50 applied in the embodiment, and the windshield member 250 also projects into the panel mounting portion 17A in the plate thickness direction. It is installed in. Therefore, also in this modification 2, the air that has entered the panel mounting portion 17A from the water draining hole 278b abuts on the windshield member 250 or proceeds while bypassing the windshield member 250, so that the momentum is weakened. It will not be discharged to the outside of the panel mounting portion 17A through the first joint portion C1 and the second joint portion C2 as it is when it has entered. As a result, even if the rainwater that has entered the inside of the panel mounting portion 17A remains without being discharged through the water draining hole 278b, it may be discharged outside together with the air that has entered through the water draining hole 278b. It is possible to prevent water leakage into the room. Moreover, when the windshield member 250 formed of sponge is applied, the weight of the windshield member 50 can be significantly reduced as compared with the embodiment, so that the windshield member 250 is disposed over the entire length of the front frame 17. Also, the weight of the front frame 17 can be reduced. In the second modification, the same components as those of the embodiment or the second modification are designated by the same reference numerals.

  In addition, although the roof structure applied to the outdoor structure 10 called a terrace enclosure is illustrated in the above-described embodiment and Modifications 1 and 2, the present invention is not necessarily limited to this. It is also possible to apply to other things.

  Further, in the above-described embodiment and the modified examples 1 and 2, the windshield members 50 and 250 are provided over the entire length of the front frame 17, but they need not be provided over the entire length. For example, the windshield members 50 and 250 may be partially provided at positions where the drain holes 178e and 278b are covered, and the first joint portion C1 and the second joint portion C2 are provided to the water drain holes 178e and 278b. Even if the windshield members 50 and 250 are arranged so as to be covered, it is possible to prevent water leakage. In the latter case, the windshield members 50 and 250 may be partially provided at positions close to the first joint portion C1 and the second joint portion C2, or the drain holes 178e and 278b and the first joint portion. It is possible to partially provide the windshield members 50 and 250 at a position between the C1 and the second joint C2. Further, the windshield members 50 and 250 do not have to be projected forward in the panel mounting portion 17A, and the windshield members may be provided so as to project backward. Further, the windshield members 50 and 250 do not necessarily have to be provided so as to face the water drain holes 178e and 278b, and for example, the windshield members may extend in the vertical direction so as to divide the inside of the panel mounting portion 17A into the left and right. A member may be provided.

  Furthermore, in the above-described embodiment, the first modification, and the second modification, drainage holes 178e and 278b are provided at four positions between the rafters 19 and the rafters 26 and between the rafters 26, respectively. Therefore, in other words, since the drainage holes 178e and 278b are provided at a plurality of positions shifted in the longitudinal direction of the front frame 17 with respect to the first joint C1 and the second joint C2. It is possible to secure a long ventilation path from the water drain holes 178e, 278b to the first joint C1 and the second joint C2, which is advantageous in preventing water leakage.
