It is set as the provided structure. Therefore, it becomes possible to provide the slit part 84 simultaneously by installing the roof panel 120 on the roof part 20 of the building 10. Moreover, since the adjacent roof panels 120 are connected by the connecting material 130 and the slit portion roof surface material 138 which are separate bodies, the size of the connecting material 130 and the slit portion roof surface material 138 is changed. It becomes possible to change the size of the slit portion 84 provided between the first roof panel constituting portion 122 and the second roof panel constituting portion 124. That is, by changing the size of the slit portion 84, the amount of air in the cabin space 62 passing through the slit portion 84 can be adjusted, so that the ventilation amount according to the scale of the building 10 can be adjusted. Thereby, while being able to improve the workability of field work, ensuring of the ventilation amount according to the building 10 becomes easy.

  Furthermore, since the position of the slit portion 84 can be easily changed by appropriately adjusting the sizes of the connecting material 130 and the slit portion roof surface material 138, it is possible to cope with a change in the mounting position of the ventilation duct 90. It becomes easy.

  The embodiment of the present invention has been described above, but the present invention is not limited to the above, and various modifications other than those described above can be implemented without departing from the spirit of the present invention. Of course.
