  As described above, in 200 of the present embodiment, the house band 300 is stretched on the outer periphery of the house 100, thereby preventing the resin sheet 110 and the skylight sheet 201 of the roof portion 120 from being rolled by strong winds. Since the band guide body 280 can support the house band 300 at a predetermined height, when the winding pipe 230 is wound or unwound, the house band 300 comes into contact with the winding pipe and the winding is performed. It is possible to prevent the take-up operation and the rewind operation from being hindered.

  Here, the opening / closing operation | movement of the skylight part 130 by the roof part opening / closing structure 200 comprised as mentioned above is demonstrated with reference to FIG. FIG. 5A is an explanatory side view showing the roof opening / closing structure 200 when the skylight 130 is opened, and FIG. 5B is an explanatory side view showing the roof opening / closing structure 200 when the skylight 130 is closed. is there.

  As shown in FIG. 5A, when the skylight portion 130 is in an open state, the winding pipe 230 is held on one end (upper end) side of the rail member 260 in a state where the skylight sheet 201 is completely wound. .

  At this time, in the side view shown in FIG. 5, the skylight sheet 201 is wound around the winding pipe 230 in a clockwise direction from the outer periphery to the inner periphery of the winding pipe 230. ing.

  When the skylight portion 130 is closed, the handle 232 of the sheet winding device 231 is rotated in the rewinding direction (the direction opposite to the winding direction), so that the winding pipe 230 is shown in FIG. While rotating counterclockwise in the side view shown, the rail member 260 is moved downward.

  Then, after the take-up pipe 230 is moved to the other end (lower end) side of the rail member 260, the handle 232 is further rotated in the same direction as the rewind direction, whereby a dashed line in FIG. As shown, the winding pipe 230 is dropped from the upper end surface of the pipe support 240 to the inclined surface side of the roof portion 120.

  Thereafter, by further rotating the handle in the same direction as the rewinding direction, the winding pipe 230 rotates counterclockwise in the side view shown in FIG. Housed inside.

  Finally, by applying turning force to the handle 232 in the rewinding direction, tension is applied to the skylight sheet 201 in the portion covering the skylight part 130, and the tension state of the skylight sheet 201 is maintained. The locking mechanism of the sheet winding device 231 is locked.

  As a result, the winding pipe 230 is held at a position locked to the pipe locking portion 246 as shown by a solid line in FIG.

  When the skylight portion 130 thus closed is opened again, the lock mechanism of the sheet winding device 231 is released, the handle 232 is rotated in the winding direction, and the open area of the skylight portion 130 is desired. When it becomes wide, the lock mechanism of the sheet winding device 231 is locked again.

  As described above, in the roof opening / closing structure 200 of the present embodiment, when the skylight portion 130 is closed, the tension of the skylight sheet covering the skylight portion 130 is simply increased by continuously rotating the winding pipe 230 in the rewinding direction. Since the skylight portion 130 can be closed while maintaining the tension state, the opening portion can be reliably closed even when a strong wind blows.

  In addition, since the roof opening / closing structure 200 opens and closes the skylight portion 130 with the skylight sheet 201, it is lighter than a conventional metal skylight and can be manufactured at a low cost.
