The intrusion of rainwater or the like between the summing rods 24, 34 of the inner / outer shoji 20, 30 and the lower frame 12, that is, from the summing unit will be described.
A third drain hole 84 is formed between the first main lower windshield plate 15-1 and the second main lower windbreak plate 15-2 on the upper surface plate 40b of the main body 40 of the lower frame 12.
The lower surface of the summing part of the inner / outer shoji 20, 30; in this embodiment, the outdoor side surface of the outdoor outward projection 52 of the lower arm 22 of the inner shoji 20, the lower surface and the main body 50 of the lower arm 32 of the outer shoji 30 The indoor side portion lower surface of the indoor side, the indoor side surface and the lower surface of the indoor side outward projection 51 are in contact with the second main lower windbreak plate 15-2, and are watertight. The third drain hole 84 falls into the hollow part 40f of the main body 40 of the lower frame 12, and is drained from the drain part 81 to the outside.
If there is rainwater or the like that does not fall into the hollow portion 40f from the third drain hole 84, the lower surface of the summing portion of the inner / outer shoji 20, 30 and the first main lower windbreak plate 15-1 Do not enter the room at the watertight area where the

As described above, rainwater or the like that has entered the indoor side of the inner / outer shoji 20, 30 may be drained out of the room through the hollow portion 40f of the main body 40 of the lower frame 12 for some reason. Rainwater or the like may enter the portion of the 1-groove 45 that faces the outer panel 30.
Therefore, as shown in FIG. 5, the fourth drainage hole 85 is formed near the other vertical frame 13 in the portion where the second groove 46 of the upper surface plate 40 b of the main body 40 of the lower frame 12 is formed, and the hollow portion 40 f of the main body 40 is formed. Communicate with.
A notch 86 is formed near the other vertical frame 13 in the inward projection 42 for the inner shrimp, and the inner impeller stopper 90 is attached to a portion where the notch 86 and the fourth drain hole 85 are formed.
The inner limb stopper 90 has a main body 91 that is provided in the second groove 46 and covers the fourth drainage hole 85, and a protrusion 92 that fits into the notch 86 provided in the main body 91. 92 and the main body 91 are provided with a drainage passage 93 that communicates the first groove 45 with the fourth drainage hole 85.

As a result, rainwater or the like that has entered the portion of the first groove portion 45 facing the shingles 30 passes through the drainage passage 93 and falls from the fourth drainage hole 85 into the hollow portion 40f of the main body 40 of the lower frame 12 to be drained. Water can be drained from the section 81 to the outside.
Further, by fitting the protrusion 92 to the notch 86, the inner limb stopper 90 can be positioned, and the notch end surface of the inward protrusion 42 for the inner limb is covered with the protrusion 92 so that it cannot be seen.
The drainage passage 93 is provided with a filter (not shown).
