Then, when reaching the lower end of the lower cover plate 20, the upper side locking piece 41a of the third cover plate 41 is positioned inside the lower side cover plate 20, so that the upper side locking piece 41a is transmitted along the outer surface of the third side cover plate 41a to the third side. Cover plate 4
Run down to the top of 1. The rainwater on the upper surface of the third cover plate 41 is lowered by the descending inclination of the upper piece 40 of the second cover plate 40.
Run down to the top of a. The rainwater on the upper surface of the upper piece 40a of the second cover plate 40 flows downward due to the gentle inclination thereof, and the outer piece 40b thereof.
It flows down and flows down. The rainwater on the outer side piece 40b of the second cover plate 40 flows down, and the inner side piece 39a of the first cover plate 39 overlaps with the inner side of the outer side piece 40b, so that the rainwater further flows down the outer surface of the inner side piece 39a and flows down. The rainwater on the inner piece 39a of the first cover plate 39 falls down to the bottom or partially wraps around the lower piece 39b. Part of the rainwater that has spilled into the lower piece 39b or part of rainwater that is sprayed from below may wrap up around the tip of the lower piece 39b, but is blocked by the packing material 38 and penetrates further into the interior. do not do.

In this way, since the rainwater is allowed to flow downward in sequence, a gap portion between the falling piece 17b of the indoor side cover plate 17 and the upper cover plate 19, a joint portion of the upper cover plate 19 and the lower cover plate 20. , Lower cover plate
20 and the third cover plate 41 joint, the third cover plate 41 and the second cover plate 40 upper piece 40a joint, the second cover plate 40 outer piece 40b and the first cover plate
It is possible to prevent rainwater from entering the joint portion of the inner piece 39a of 39, the lower piece 39b of the first cover plate 39 and the gap portion of the lower surface 30 of the convex wall 2.

In the embodiment shown in the drawings, the mounting means for the brackets is composed of the concave portion 13 and the plurality of convex portions 14 fitted to the concave portion 13, but not limited to this, a plurality of concave portions 13 may be provided, Alternatively, the concave portion 13 and the convex portion 14 may be provided on the opposite surfaces on the opposite sides, respectively.

Further, the connecting means for simultaneously covering the cover plate is constituted by the locking groove 23 and the plurality of projections 24 engaged by the locking groove 23, but is not limited to this, and the locking groove is not limited to this.
A plurality of 23 may be provided, or the locking groove 23 and the locking groove 23 may be respectively provided on the opposite surfaces on the opposite side.
