The seal member 9 is formed into a deformable tube shape from a soft material such as synthetic rubber, and the seal members 10 and 21 are formed into a band shape from an elastic material.

Then, overhead door 1 is closed,
At the same time that the lowermost door panel 2 is lowered to the bottom of the groove B, the seal member 9 deforms and comes into close contact with the bottom of the groove B, the seal member 10 comes into close contact with the inner side of the groove B, and the seal members 21, 21 are in close contact with the left and right frame members 22, 22 of the entrance/exit A, thereby ensuring water-tightness at the lower end and both left and right ends of the overhead door 1.

Brackets 11 are located at both the left and right ends of the lowermost door panel 2 on the indoor side, located at the lower and upper ends.
11 is provided in a protruding manner, and press rollers 12, 12 are attached to these brackets 11, 11, respectively.

Furthermore, a door press angle 13 and an angle operating arm 14 are attached to the left and right sides of the entrance A.

The lower end of the door press angle 13 is pinned to a bracket 16 protruding from the side of the doorway A, and a tongue piece (not shown) that interlocks with the press roller 12 is provided at the lower end, and the door panel 2 It can be raised and folded to the side, and one side portion 13a faces the press rollers 12, 12 in the indoor/outdoor direction. When the overhead door 1 is lowered to the bottom of the groove B, the door press angle 13 is erected along the inside of the door panel 2 by interlocking the tongue piece with the press roller 12. , one side 13
A is configured to strongly press the press rollers 12, 12. The angle operating arm 14, like the door press angle 13, is attached to a bracket 16 protruding from the side of the entrance A so as to be rotatable about a shaft 17.

The angle actuating arm 14 is located on the back side of one side 13a of the door press angle 13, and presses the door press angle 13 more strongly from the back side using a lever principle, thereby raising the door press angle 13 vertically. In addition, the door press angle 13 and the lowermost door panel 2 can be strongly pressed toward the outside of the room.

Further, a substantially rectangular recess C is formed on the floor surface of the entrance A and is located on the indoor side of the door panel 2. The recesses C are formed at regular intervals in the width direction of the entrance A, and a backup post 15 is removably bolted to each recess C with a plurality of anchor bolts 18.
