By providing the ventilation holes 24 in this way, As shown by the arrow a in FIG. 1 (a), the eaves or the ceiling 26 of the room is ventilated. By providing the storage box body 2 with the vent holes 24 as described above, by installing the storage box body 2, the ventilation port is separately provided.
Without providing 24, simply installing the storage box 2 allows the ceiling space 26 and the outside 25 to communicate with each other through the ventilation hole 24 to perform ventilation. On the lower surface of the top plate 2a, as shown in FIGS. 2 and 3, in the front-back direction (indoor / outdoor direction) at regular intervals.
A rail 6 is attached to the rail 6, and a slide rod 7 is slidably fitted in the rail 6. A pair of support rods 8 are hung from the slide rods 7, and the lower ends of the support rods 8 are connected to eaves gutter suspenders 9 that suspend and hold the eaves gutter 1. The eaves gutter 1 is moved back and forth as the slide rod 7 slides in the rail 6. A bolt 10 is provided so as to project rearward (backward from the inside of the storage box body 2) from the ear holding body 9a provided on the eaves gutter suspension device 9. The rear end of the bolt 10 is supported by a sprocket 11 attached to the top plate 2a of the storage box 2. A female screw is formed on the inner surface of the sprocket 11, and the sprocket 11 is screwed into the bolt 10. This sprocket 11 is a pair of holding plates hanging below the top plate 2a.
The bolts 10 are rotatably arranged between the sprocket 11 and the sprocket 11 so that the bolt 10 moves back and forth with respect to the holding plate 12 as the sprocket 11 rotates.
The sprocket 11, the bolt 10, the support rod 8, the slide rod 7 fitted to the rail 6 and the like constitute the front-back moving means A. The front-rear moving means A is arranged on the lower surface of the top plate 2a at regular intervals along the longitudinal direction of the eaves gutter 1. A chain 13 is stretched over each adjacent sprocket 11, and each sprocket 11 is rotated by driving the chain 13. The chain 13 constitutes a tuning means C for tuning the adjacent front-rear moving means A. The rotation of the chain 13 simultaneously drives the adjacent front-rear moving means A, and the eaves gutter 1 is driven simultaneously. The moving means A is adapted to move back and forth simultaneously over the entire length.

In the embodiment shown in FIGS. 2 and 3, the forward / backward moving means A is provided at two places, but the present invention is not limited to this and provided at two or more places. You may be like this.

On the lower surface of the top plate 2a constituting the storage box body 2, one driving means B for driving the above-mentioned front-rear moving means A is provided.
