This is because they are slidable in the axial direction of the corresponding shaft 33a via the metal 33d.

When the door body 30 moves parallel to the rear side in this way, the guide rollers 16, 16 on the wall W side enter the corresponding cutouts 32a, 32a. , 15 to effectively prevent water from entering the entrance A of a building or the like from the outside. This is because the packings 17, 21, and 15 are crushed by the rear surface of the door main body 30, and can seal both side edges and the lower end edge of the door main body 30 in a watertight manner.

When the door body 30 is opened, the eccentric rollers 42 are rotated from the sealing position to the releasing position via the manual handle 41. At this time, the eccentric roller 4
Are rotated while abutting against the fixing members 18 and 22 on the side of the wall W, and the door body 30 is moved parallel to the direction of separating the door body 30 from the walls W and W, that is, the front side of the door body 30 (FIG. 3). 5 (solid line in FIG. 5), the seals 17, 21 and 15 can be broken. Therefore, the door body 30
Thereafter, the opening operation can be performed lightly. In addition,
When the eccentric rollers 42, 42,... Are in the release position in this manner, the tip of each eccentric roller 42 is at the same level as the surfaces of the walls W, the fixing members 18, 22 on the W side. However, since small slopes 18a and 22a are formed at predetermined corners of the fixing members 18 and 22,
2 does not cause unnecessary interference with the fixing members 18 and 22 when the door body 30 is closed again.
It is possible to smoothly enter between the fixing members 18 and 19 and the fixing members 22 and 23.

In the above description, when the door body 30 is opened, the upper surface of the base member 13 may be removably closed by the lid member 51 (FIG. 7). The lid member 51 is positioned by the edge plates 13c, 13c of the base member 13, and may be formed by attaching a leg 51b to the lower surface of the lid plate 51a so as to fit into the groove 13b of the base member 13 including the rail 14. it can. The cover plate 51a may be divided into suitable lengths in the longitudinal direction of the base member 13 for easy handling, or may be provided with an embedded open / close handle (not shown). In any case, it is assumed that the lid member 51 does not hinder a person or a car passing through the entrance A of a building or the like and has sufficient strength to withstand them.

The length L of the door body 30 can be arbitrarily determined according to the opening width w of the entrance A of a building or the like. In the case where the length L of the door body 30 is a long span of several meters or more, two or more guide columns 1 along the front surface of the wall W.
1, 11,... May be provided.
