By interlocking with 40, the operation mechanism 40 can be physically linked to the blind 4 side in the space 12 via the operation interlocking body 30, and a magnet can be made unnecessary for opening and closing the blind 4. .

  In addition, since the sealing part 35 seals the portion where the rotary shaft 22 is taken out to the outside air, the sealing in the space 12 between the two glass plates 10 and 10 can be secured, and the blind 4 can be opened and closed. In a configuration that does not use a magnet, it is possible to prevent the heat insulation and dew condensation prevention functions of the double-glazed glass 1 with built-in blinds from being impaired.

  In order to improve the airtightness of the glass body 2, a sealing material 38 is further applied to the outer peripheral surface of the glass body 2 outside the sealing portion 11. FIG. 7 shows a perspective view of the glass body 2 near the operation interlocking body 30. As shown in this figure, in the operation interlocking body 30, the external connection portion 34 is an exposed portion that protrudes outward from the region between the two glass plates 10 and 10. A receiving surface portion 37 facing the direction orthogonal to the outer peripheral surface of the upper side of the glass plate 10 is formed at the upper end portion, and a receiving surface portion 37 facing the direction orthogonal to the outer peripheral surface of the vertical side of the glass plate 10 at the lower end portion. Are formed.

  As indicated by a broken line in FIG. 7, the sealing material 38 is applied so as to be substantially continuous with the outer surface of the operation interlocking body 30 with the receiving surface portion 37 of the operation interlocking body 30 as an end. Thereby, while applying the sealing material 38 easily, airtightness can be made high over the perimeter of the glass body 2 including the part of the operation interlocking body 30. FIG.
