Since the base portion 31 and the attached portion 33, which are the extension sources of the extension portion 34, and the attachment portion 11 of the frame 1 are also closed, the gap between the frame 1 and the door 2 is closed. Water F can be prevented from entering the indoor space from the outdoor space through the gap between the frame 1 and the door 2, and the watertightness is excellent.

Further, the tight material 3 provided in the fitting of the present invention has a large expected width of the inner peripheral portions 30c and 30d provided along the vertical frames 10c and 10d, and the inner peripheral portions 30c and 30d provided along the lower frame 10b. Since the peripheral portion 30b has a large found width, the surface in which the door contact portion 32 and the door 2 are in close contact with each other is sufficiently large, so that in a normal state, the airtightness between the frame 1 and the door 2 is excellent and water is flooded. At times, the tight material 3 is crimped to the frame 1 and the door 2 by the force applied by the water pressure of the water F, so that the water F from the outdoor space to the indoor space through the gap between the frame 1 and the door 2 It can prevent intrusion more reliably and has excellent watertightness.

In addition, the back leakage prevention portion 35 can be attached to the frame 1 in advance at the time of shipment from the factory of the frame 1, and a release material can be attached to the surface to be adhered to the extension portion 34 of the tight material 3. Therefore, when constructing the fittings, it is only necessary to peel off the release material and bond it to the frame 1, so that the construction is easy.

The present invention is not limited to the above-described embodiment, and can be appropriately modified as long as it is within the scope of the claims. For example, the fitting may be a sliding window or a hinged window, the tight material may be continuously attached to the entire circumference of the frame, and if the material of the tight material has water resistance, EPDM rubber may be used. And it does not have to be an EPDM sponge. Further, the back leakage prevention portion of the tight material may be integrally molded with the extension portion. In that case, at the time of shipment from the factory of the frame, a release material is provided on the surface of the back leakage prevention portion to be adhered to the frame. It is affixed, and when constructing the fittings, it is only necessary to peel off the release material and adhere it to the frame, so the construction is easy, and the gap between the frame and the door is closed, and the airtightness is excellent in normal times. At the same time, when flooded, the tight material is crimped to the frame and door by the force applied by water pressure, so it is possible to prevent water from entering the indoor space from the outdoor space through the gap between the frame and the door, and it is watertight. Excellent in sex.
