る。 Hereinafter, the present invention will be explained based on the embodiments shown in the drawings. Incidentally, the same reference numerals are used for the same parts as in the past. FIG. 2 shows an embodiment of the present invention. As shown in the figure, in this embodiment, O-rings 4 and 5 are interposed in the gap between the end surfaces of the glass plate 1 on the vacuum side and the atmosphere side and facing the mounting bracket 2 and the mounting seat 3, as in the conventional case. . Furthermore, the cross section of glass 1 (outer peripheral surface)
Attach O-ring 6 to. After that, attach the mounting bracket 2
Tighten and fix the mounting seat 3 with bolts, etc. With this structure, when the vacuum is drawn, a gap g 1 is secured between the glass plate 1 and the mounting bracket 2 by the O-rings 4 and 5, and a gap g 1 is secured between the glass plate 1 and the mounting seat 3. gap g 2 is secured. Further, the O-ring 6 secures a gap g 3 between the glass 1 and the fitting portion of the mounting seat 3 into which the glass 1 is inserted.

方のＯリングによつて真空シールが確保される。 Therefore, due to the presence of gaps g 1 , g 2 , and g 3 between the glass plate 1, the mounting bracket 2 , and the mounting seat 3 ,
There is no direct contact and there is no risk of the glass plate 1 breaking. Moreover, on the vacuum side, O-rings 4 and 6 are
Because of the presence of the O-ring, a double vacuum seal is formed, and even if one O-ring becomes defective, the vacuum seal is ensured by the other O-ring.

構造となるために信頼性の向上が図れる。 According to this embodiment, the atmosphere side and the vacuum side of the glass plate. A gap is provided on the outer circumferential side of the mounting bracket to prevent damage during factory assembly, transportation, etc. Furthermore, since the vacuum seal has a double structure, reliability can be improved.
以上より明らかな如く本考案によれば、信頼性
の高い真空容器用のぞき窓を得ることができる。 As is clear from the above, according to the present invention, a highly reliable viewing window for a vacuum container can be obtained.
