The shape holding member 2 includes a pair of left and right side pieces 1.
1, 11 and a connecting piece 12 for connecting them are formed integrally, and the pair of side pieces 11, 11 extend from the connecting piece 12 so as to expand. As a result, the width of the connecting piece 12 is reduced, so that the material is not wasted and the insertion into the frame B is facilitated. A pair of left and right reinforcing members 4 and 4 are welded to the inner surfaces of both ends of the connecting piece 12,
The reinforcing member 4 is made of a soft resin like the sealing member 3. Drainage holes 13 are formed at intervals in the shape holding member 2 of the bead 1 for a double-glazing unit incorporated into the lower side of the double-glazing unit A (see FIG. 3). The drain hole 13 drains rainwater that has entered between the multilayer glass A and the bead 1 for multilayer glass, and the reinforcing member 4 forms a gap between the multilayer glass A and the shape maintaining member 2. Then, rainwater is led to the drain hole 13. In this case, FIG.
As shown in (1), the outermost water drain hole 13a is formed by cutting out the outer end of the shape holding member 2. Thereby, drainage of the corner portion of the double-glazed glass A into which rainwater easily enters can be positively performed. Although not particularly shown, the reinforcing member 4 and the shape holding member 2 may be integrally formed.

Each seal member 3 is welded to the outer frame seal portion 21 which is in close contact with the frame B, the outer upper glass seal portion 22 and the lower glass seal portion 23 which are in close contact with the multilayer glass A, and the shape holding member 2 is welded. And a lower welding portion 24 to be formed. The frame seal portion 21 is depressed in an inverted “L” shape, and closely adheres to the inner corner of the frame B in a hooked state. The upper glass seal portion 22 and the lower glass seal portion 23 are formed in a wedge shape, and are respectively pressed up and down to be in close contact with the multilayer glass A. The welding portion 24 is formed in the shape of a fin, and is welded to the inside of the upper end of the shape holding member 2. This welding is performed by bringing the hard shape holding member 2 and the soft seal member 3 into contact with each other when both are in a semi-cured state when they are extruded.

As described above, according to the first embodiment of the present invention, each seal member 3 has the frame seal portion 21, the upper glass seal portion 22, the lower glass seal portion 23, and the welding portion 24. Since they are integrally formed, manufacturing becomes easy and the manufacturing apparatus can be simplified. Further, since each seal member 3 is welded to the inside of the upper end portion of the shape holding member 2, the elasticity of the seal member 3 itself is not impaired, and the seal member 3 is attached to the multi-layer glass A. Even if the force for peeling off the shape holding member 2 acts on the
Since no force in the peeling direction acts on the welded portion 24, the seal member 3 does not peel off from the shape holding member 2. Therefore, the reliability of the product can be improved.

Next, a second embodiment of the present invention will be described with reference to FIG. In the second embodiment, the shape holding member 2 is formed in a “U” shape, and each seal member 3 is formed.

As shown in FIG. 3, in the double-glazed glass body 30 of this embodiment, the bead 1 for double-glazed glass has a length corresponding to the four sides of the double-glazed glass A, and both ends thereof have an angle of 45 degrees.
Each time it is cut, it is incorporated into the double-glazed glass A. In this case, the corners joined at 45 degrees are preferably sealed with a caulking material or the like.
It is preferable that each bead 1 for double glazing sandwiched between the double glazings A by the spring force is bonded to the double glazing A at several places with an adhesive.

As described above, by cutting the bead 1 for a double-layer glass and incorporating it into the double-layer glass A, the bead 1 for a double-layer glass can be adapted to the double-layer glass A.
Of the double-layer glass bead 1 can be prevented from falling off before being incorporated into the substrate. Further, by joining the corner portions at 45 degrees, the joining portion can be long, and the sealing property of this portion can be enhanced.

As shown in FIG. 4, in the double-glazed glass body 40 of this embodiment, the double-glazed glass bead 1 is cut into a length corresponding to four circumferences of the double-glazed glass A, and A V-shaped cut 1a having an angle of 90 degrees is formed in a portion corresponding to a corner (corner), and the cut 1a is bent at the cut to be incorporated into the double-glazed glass A. Also in this case, similarly to the above, the cut end is cut at an angle of 45 degrees. On the other hand, the V-shaped cut 1a extends from the seal member 3 to the side piece 11 of the shape holding member 2, while the connecting piece 12 of the shape holding member 2 is left. Thereby, the radius of the corner portion can be reduced, and the bead 1 for a double-glazing unit and the corner portion of the double-glazing unit A can be satisfactorily blended. In addition, even if the connecting piece 12 is broken when it is bent, the reinforcing member 4 allows the double-glazed glass bead 1 to maintain the connected state.

Although not shown, the cut end of the seal member 3 is cut so as to slightly protrude from the cut portion. When the cut end is bent at 90 degrees, the cut ends of the seal member 3 have priority over each other. , So that the airtightness of this portion can be maintained.
