In other words, it is pushed into the frame 4 side. On the other hand, the water pressure state is a state in which a predetermined amount of water pressure acts on the door bodies 2 and 3 from the outdoor space side. In the water pressure state, when the water pressure acts on the door bodies 2 and 3 from the outdoor space side, the water blocking door 1 has one vertical water blocking rubber 61, the other vertical water blocking rubber 62 and the upper water blocking rubber 63. The door end side of the lower water stop rubber 64 is sufficiently crushed in the pressing direction P between the frame body 4 and the door bodies 2 and 3, and the summing water stop member 70, the auxiliary water stop member 80, etc. 2 and the main door 3 are sufficiently crushed in the pressing direction P, and appropriate water stopping performance can be ensured.

  According to the water blocking door 1 according to the embodiment described above, the frame-shaped water blocking member 60, the contact portion 50, and the summing water blocking member 70 are in a state where the pair of door bodies 2 and 3 are in the closed position. Since the auxiliary water stop member 80 interposed therebetween is provided, the frame-like water stop member 60, the contact portion 50, the summing water stop member 70 and the like are pressed while the pair of door bodies 2 and 3 are in the closed position. Thus, the auxiliary water stop member 80 is elastically deformed. And the water stop door 1 adheres to the frame water stop member 60, the contact part 50, the summing water stop member 70, etc. with the elastic restoring force of the auxiliary water stop member 80, frame shape, It can suppress that a clearance gap produces between the water stop member 60, the contact part 50, the summon water stop member 70, etc. FIG. Therefore, even if the water stop door 1 includes the pair of door bodies 2 and 3, the water stop performance can be improved.

  Moreover, since the water stop door 1 is provided with the auxiliary water stop member 80 in the frame-like water stop member 60, when the pair of door bodies 2 and 3 closes the opening O, the water stop door 1 hits the auxiliary water stop member 80. 50 and the summing water stop member 70 will overlap. For this reason, it can suppress that the auxiliary | assistant water stop member 80 produces a clearance gap between the frame-shaped water stop member 60, the contact part 50, and the summon water stop member 70. FIG.

  Furthermore, since the auxiliary water stop member 80 is more easily deformed than the frame water stop member 60, the water stop door 1 is pressed from the frame water stop member 60, the contact portion 50, and the summing water stop member 70. It is possible to further suppress the auxiliary water stop member 80 from being elastically deformed and generating a gap between the frame water stop member 60, the contact portion 50 and the summing water stop member 70.

[Modification]
The water stop door 1-1 which concerns on the modification of embodiment is demonstrated with reference to FIG. FIG. 8 is a cross-sectional view illustrating an auxiliary water stop member of a water stop door according to a modification of the embodiment.
