The translucent plate 60 can be arranged substantially flush with the roofing member 20 without the need to be formed at a position projecting to the outside of the roof 20. Further, since it is not necessary to project the translucent plate 60 to the outside of the roofing material 20, the depth of the daylighting passage 41 between the translucent plate 60 and the ceiling can be reduced. Therefore, the light emitted from the outside to the inside of the room through the translucent plate 60 is not regulated by the daylighting passage 41, and it is possible to irradiate the outside light to a wide range in the room, and thus the more light can be collected. The effect can be obtained. That is, the skylight 30 according to the present embodiment can take in more light into the room and can make the room brighter than a skylight having the same area in which the daylighting passage 41 is projected outside the room.

Furthermore, the overlapping state of the roof extending member 20 and the upper extending portion 65 and the lower extending portion 66 of the outdoor side glass 61 can be formed in the same manner as the overlapping state of other roofing members 20.
That is, the line of the overlapping portion of the roofing material 20 formed in other than the skylight 30, in the skylight 30 according to the present embodiment, there is no aluminum frame or the like exposed on the roof surface, the roofing material
It is connected to the line of the overlapping portion of 20 and the outdoor glass 61. Therefore, the line of the overlapping portion of the roofing material 20 can be continuously formed in the skylight 30 without being interrupted when viewed as the appearance of the entire roof. As a result, a part of the roofing material 20 is replaced with the outdoor glass 61, the appearance of the roof surface can be cleaned, and the roof appearance can be improved.

As described above, the skylight 30 according to this embodiment.
Has a simple structure.
The skylight 30 excellent in watertightness can be easily formed easily. As a result, the construction at the site can be simplified and the manufacturing cost can be reduced. Further, since the structure is not complicated and has a simple structure, even if an object is blown by a strong wind such as a typhoon and hits the translucent plate 60 and is damaged, a plurality of parts are stopped at the side edge of the outdoor glass 61. The damaged translucent plate 60 can be removed by simply removing the screws 84 ,.

By disposing a new transparent plate 60 in the roof opening 11 and screwing it again with the screw 84, the transparent plate 60 can be easily replaced, and repair work or The replacement work can be easily performed.
