No. 6 pamphlet (1997)), the spacer body is arranged between both plate glasses of the double glazing, and sandwiched between the two plate glasses so that the adhesive can be attached so as to be in close contact with the inner surface of the plate glass. It was there.
This multi-layer glass spacer has a feature that it can be installed more easily and speedily than a type in which a spacer body is placed between both plate glasses and then a sealing material is filled to maintain hermeticity. And in order to maintain the heat insulation performance of the double glazing itself, the spacer body is
Generally, it is often made of a material having a high heat insulating property (for example, a synthetic resin such as nylon-based or acrylic-based resin).

題点がある。According to the above-mentioned conventional technique for the spacer for double glazing, the spacer body can be installed easily and speedily, but the spacer body is made of the synthetic resin as described above. If configured, the spacer body has a high moisture permeability over the long term (by the way, the moisture permeability is about tens to hundreds of times that of butyl rubber, which is often used for spacer filling seals). Through the outside, moisture from the outside enters into the inner space of the double-glazing to cause dew condensation, and the aesthetic appearance and value of the double-glazing are likely to be deteriorated. That is, there is a problem that the durability of the double glazing tends to be low.

This is to improve the durability of double glazing.

And a nut outer fitting portion 15b formed to have an inner diameter substantially equal to the outer diameter of the first holding portion 18 of the first nut 7A. The spacer body 15 is made of nylon. On the other hand, the outer peripheral portion of the spacer body 15 is provided with a collar-shaped portion 15c extending over the entire circumference at an intermediate portion in the axial direction. Further, a ring-shaped moisture suppressing member (corresponding to a moisture suppressing portion) 20 that suppresses mutual moisture flow between the bolt 5 and the space V is provided further outside the collar-shaped portion 15c.
As shown in FIG. 5, the moisture suppressing member 20 has a circumferential groove portion 20a which can be fitted with the brim portion 15c formed all around the inner circumferential portion, and the circumferential groove portion 20a is formed in the brim portion 15c. The moisture suppressing member 20 and the spacer body 15 can be integrated with each other by fitting the above. The peripheral groove portion 20a
And the brim-shaped part 15c constitute a fitting connection part 23. Further, the moisture suppressing portion 20 is formed to be elastically deformable, and the spacer main body 15 is formed on both end surface portions.
A pushing portion 24 extending from the abutting portion 16 in the axial direction of the ring.
Is provided. Therefore, when it is installed together with the spacer body 15 between the two plate glasses 2 and sandwiched between the fixing bolt 6 and the fixing nut 7, the pressing portion 24 receives the force from the plate glass 2 and elastically deforms, and the surface of the plate glass 2 is pushed. Close to
It can be installed in a state in which moisture circulation can be more easily suppressed. Incidentally, the moisture suppressing member 20 is made of a copolymer of butyl rubber and polypropylene, has a moisture permeability coefficient of 0.6 ((g · mm / m 2 · day), and an air temperature of 37.
It is less than about 8 ° C. and 90% humidity), and it is extremely difficult for moisture to pass through. For hardness, Shore A hardness 3
It is about 0 to 75 (more preferable hardness is 65) and is set so as to be deformed into a preferable state by receiving a force from the glass plate.

It may be made of another synthetic resin, metal, wood, or the like. Further, it may be configured by using the same material as the moisture suppressing portion and having an appropriate hardness. <2> The moisture suppressor is not limited to the one composed of the copolymer of butyl rubber and polypropylene described in the above embodiment, and may be, for example, EPDM or PP.
It may be composed of a copolymer of, in short, a moisture permeability coefficient of 5 ((g · mm / m 2 · day) and an air temperature of 37.8.
℃, humidity 90%) or less (preferably 2.5
(G / mm / m 2 · day or less) and hardness of Shore A hardness of 30 to 75 (more preferable hardness is 6).
It may be about 5), and they are collectively referred to as a moisture suppression section. Further, if the desiccant is kneaded together in the moisture suppressing portion, it becomes easy to maintain the drying environment of the space V by the desiccant located in the portion facing the space V. <3> The adhesive material layer 21 is not limited to the one made of the acrylic material described in the above embodiment, and may be made of, for example, a butyl material, and further has a ring shape. A butyl-based material (outer side) and a ring-shaped acrylic-based material (inner side) may be concentrically combined. Thereby, the moisture suppression effect is further improved. <4> The spacer body and the moisture suppressing portion are not limited to being formed separately as described in the above embodiment, but may be integrally formed. Therefore, when the spacer body and the moisture suppressing portion are integrally formed, it is not necessary to provide the fitting connecting portion. Further, the configuration of the fitting connection portion can be appropriately changed other than the configuration of the collar-shaped portion and the circumferential groove portion described in the above embodiment. Further, the spacer body 15 may be made of a material having a low moisture permeability coefficient. <5> A butyl-based material may be disposed between the moisture suppressing portion and the plate glass, which further improves the adhesion and the moisture suppressing effect. In this case, it is preferable to attach release paper that integrally covers the surface of the butyl material together with the surface of the adhesive layer. As a matter of course, the release paper may be a separate release paper that covers each of them separately.
