The internal dimensions are set so that the member 71 can be moved by a predetermined amount also in the door width direction.

More specifically, the dimension X corresponding to the door width in the engaging hole 72a is the diameter of the rod-shaped member 71 to be inserted so as to absorb play, inclination, etc. in the door width direction of the first door body 21. It is set to several times.
Further, the dimension Y corresponding to the door thickness in the engaging hole 72a is set in the rod-shaped member 71 before and after the movement when the first door body 21 projects the rod-shaped member 71 and moves from the closed position to the water stop position. The engaging holes 72a are set to fit.

In other words, the internal dimensions of the engaging hole 72a are such that when the first door body 21 is in the closed position in substantially contact with the frame-side water blocking member 2, the rod-shaped member 71 is closer to the opening direction in the engaging hole 72a (FIG. 11). When the first door body 21 compresses the frame-side water blocking member 2 by a predetermined amount and is in the water stopping position due to proximity or contact with the inner wall (according to (a)), the rod-shaped member 71 is engaged. It is set so as to be close to or in contact with the inner wall of the joint hole 72a near the closing direction.
According to the illustrated example, the dimension Y in the door thickness direction of the engaging hole 72a is smaller than the dimension X in the door width direction of the engaging hole 72a, and is set to about 2 to 3 times the diameter of the rod-shaped member 71. Will be done.

Further, in the first door pressure welding device S1 (see FIGS. 1 and 2), the engaging member 31 that appears and disappears from the door tail surface of the first door body 21 by an external operation is a concave engaged portion on the frame body 10 side.
