On the side surface), the outer peripheral side portion is pressed against the airtight member 1 on the frame body 10 side and the water blocking member 2 on the frame side.

Next, after rotating the second door body 22 to the closed position, if the second door body 22 is pushed downstream by the operation of the engagement / disengagement mechanisms 33 and 34, the back surface side of the second door body 22 The outer peripheral side portion is pressed against the airtight member 1 on the frame body 10 side and the frame side water stop member 2, and further, on the door end side of the second door body 22, the combined water stop member 22a is the first. It is pressed against the stepped receiving portion 21b of the door body 21 (see FIG. 6).

Then, the first door body 21 and the second door body 22 which are in the water stop position as described above have a vertical cross-sectional bow shape so as to bend the central side in the vertical direction toward the indoor side when water pressure is applied from the outdoor side. Try to transform into. However, this deformation is suppressed by the structure on the door end side of the first door body 21 and the second door body 22.

More specifically, the door end side of the first door body 21 has a configuration of vertical aggregates 21e, 21f, 21g, 21h, a step portion 21c21, etc. within a predetermined width X1, and the door end side of the second door body 22. The deformation of the vertical cross-sectional bow shape is smaller than that on the side.
Therefore, the combined water blocking member 22a on the door end side of the second door body 22 is pressed against the first receiving portion 21b on the door end side of the first door body 21 having relatively small deformation with substantially equal surface pressure. Be done. Therefore, it is difficult for a gap to be formed between the first receiving portion 21b and the combined water stopping member 22a, and high water stopping performance can be obtained.

Further, when the first door body 21 and the second door body 22 are subjected to water pressure as described above, the first door body 21 and the second door body 22 are deformed into a bow shape in the cross section also in the width direction. Therefore, inside the first door body 21 and the second door body 22, the lateral aggregates 21p, 22o, 22p, and 22q (see FIGS. 3 and 4) are plate-shaped portions 21c2, 22c2 (see FIGS. 3 and 4) on the indoor side, respectively. (See FIG. 5).
At this time, since the elastic member 21q is interposed between each of the lateral aggregates 21p, 22o, 22p, and 22q and the plate-shaped portion 21c2 (or 22c2) (see FIG. 7), the plate-shaped portion 21c2 (or 22c2) It is possible to prevent the horizontal aggregate 21p (22o, 22p or 22q) made of metal from directly contacting the door body 21 and the indoor side surfaces of the first door body 21 and the second door body 22 from being deformed.

Further, according to the illustrated example, even if the support member 31e falls inside the door due to a work error when attaching the opening / closing knob 6, the locking mechanism 7, the engaging / disengaging mechanism 31, 33, 34, and the like. The support member 31e can be received by the transverse aggregates 21p, 22o, 22p or 22q.
In addition, the support member 31e which falls on the door tip surface and the door tail surface of the first door body 21 and the second door body 22 and is located on the lateral aggregates 21p, 22o, 22p or 22q is taken out of the door. An opening (not shown) for the purpose is provided so as to be openable and closable.

According to the above embodiment, the numbers of aggregates in the first door body 21 and the second door body 22 are made different as a means for making a difference in the bending strength of the left and right first door body 21 and the second door body 22. However, as another example of the above means, the left and right door bodies have different wall thicknesses of aggregates, the left and right door bodies have different shapes of aggregates, and the left and right door bodies have different door thicknesses. It is also possible to have a mode in which the thickness of the plate-shaped portion is different, a mode in which materials having different bending strengths are used for the left and right door bodies, and the like.

According to the above embodiment, the cross aggregates 21p, 22o, 22p, 22q are used as members for receiving the support member 31e when accidentally dropped, but as another example, these cross aggregates are used for other purposes. It is also possible to use the mode used for (for example, supporting a window or a damper device, reinforcing a door body, etc.).

Further, according to the above embodiment, the elastic member 21q is provided on the downstream side surface of the transverse aggregate, but as another example, the elastic member 21q is omitted and the transverse aggregate 21p, 22o, 22p or 22q is plate-shaped. It is also possible to have a gap between the portions 21c2 and 22c2.

Further, as another example, elastic members 21q are provided on the downstream side surfaces of the vertical aggregates 21e to 21m of the first door body 21 and the vertical aggregates 22e to 22k of the second door body 22, and these vertical aggregates are used as doors. It is also possible to prevent the plate-shaped portion of the body surface from being deformed.

Further, according to the above embodiment, the lateral aggregates 21p, 22o, 22p, 22q, the elastic member 21q and the like are provided for the two left and right door bodies of the double door type, but as another example, the single door type of the single door type is provided. It is also possible to provide the lateral aggregate, the elastic member, and the like on one door body or a sliding door that opens on both sides or on one side.

Further, according to the above embodiment, the upstream side of the water stop door A is the outdoor side, and the downstream side of the water stop door A is the indoor side. The indoor side and the downstream side can be the outdoor side. In such a case, the configuration of the water stop door A in the thickness direction may be reversed from that shown in the drawing.

Further, the present invention is not limited to the above-described embodiment, and can be appropriately changed without changing the gist of the present invention.
