A pivotal action occurs due to the pivotal support of the hinge S1 and the hinge receiver S2, and the hinge S3 and the hinge receiver S4, and the door 1 can be rotated 180 °.

First Embodiment FIGS. 2 and 3 show a closed structure of a door device according to a first embodiment of the present invention. With reference to FIGS. 2 and 3, in the first embodiment, a recessed fitting groove 11 is formed in the lower penetration 10 of the door, and the sheath member 2 is provided in the fitting groove 11. Two mounting frames 3 for mounting the sealing plate are provided in the sheath member 2 so as to be vertically movable. The sealing plates 4 and 4 are attached to the front and rear sides of the attachment frame 3. The fitting groove 11 formed in the bottom penetration 10 of the door is formed by bending the lower ends of the panels 13 on the front and rear surfaces of the door inward, and by inserting both ends of the opening of the U-shaped groove bottom member 12 into the panel. It is fixed in a state where it is inserted and sandwiched in the bent both ends of the lower end of 13. As a result, the fitting groove 11 is formed in the shape of a concave groove that opens downward.

The sheath member 2 is provided in the fitting groove 11 and has an opening at the bottom. Both ends of the sheath member 2 are curved toward the inner surface to form a locking portion 20, and a sill plate 22 is formed in the central portion in the longitudinal direction, and the lower end of the sill plate 22 projects forward and backward and has an inverted T shape. To form the locking portion 22a. As a result, fitting gaps A and B are formed in the sheath member 2 along which the two mounting groove-shaped mounting frames 3 and 3 in the longitudinal direction are mounted.

The mounting frames 3 and 3 are U-shaped frame bodies that are fitted in the fitting gaps A and B formed in the sheath member 2 so that they can be moved up and down, respectively. It has a sealing unit fitting groove 30 that opens toward. Further, the lower ends 31, 31 of the respective mounting frames 3, 3 come into contact with the locking portions 20, 22a of the sheath member 2, and the mounting frames 3, 3 are fitted by the locking action of the locking portions 20, 22a. It is possible to prevent the gaps A and B from falling off.

The sealing plate 4 is formed of a long plate-shaped soft elastic material, and has a head portion 40 at one end inside and is fitted into the fitting groove 30 of the mounting frame 3. One end of the outer side of the sealing plate 4 is a thin plate having a triangular cross section and contacts the threshold C with appropriate elasticity.

The spring 5 has its upper end abutting the sheath member 2 and its lower end abutting the mounting frame 3, so that the mounting frame 3 is constantly pressed downward by an elastic biasing force.
