The opening/closing body 10 is a door that opens and closes an opening inside the frame body 20, and a door end portion is rotatably supported by one side frame member 22.
This opening/closing body 10 is constructed such that a front plate and a back plate are supported by aggregate, core material, etc. between them (see FIG. 2).

The frame body 20 includes left and right side frame members 21 and 22, an upper frame member 23 connected between the upper ends of these side frame members 21 and 22, and a lower frame connected between the lower ends of the side frame members 21 and 22. The member 24 (sometimes referred to as a shoe slide) has a rectangular frame shape in front view with an opening in the center (see FIG. 1).
The side frame members 21 and 22, the upper frame member 23, and the lower frame member 24 are welded together in advance at a factory or the like.

The inside surface of the side frame member 21 is formed into a substantially L-shaped cross section (see FIG. 3) that fits into the door end side of the opening/closing body 10, and an elastic airtight material 26 is provided at the indoor corner of the side frame member 21. It will be done.
The frame inner surface of this side frame member 21 is a facing surface 21a that faces the door end side end 10a of the opening/closing body 10 with a gap s therebetween.

The elastic airtight material 26 is made of an elastic material (for example, rubber, elastomer resin, etc.) and is formed into a long shape that spans substantially the entire length of the side frame member 21 in the vertical direction. The elastic airtight material 26 is pressed against the indoor corner of the opening/closing body 10 on the doorward side, thereby improving the closing performance (airtightness, watertightness, soundproofing, etc.) of the opening/closing body 10.

The side frame member 22 is laterally symmetrical to the side frame member 21 . This side frame member 22 is provided with an elastic airtight material 26 in the same manner as the side frame member 21.
