シール用エアーはこの場合は入れない。Since the gasket loading portion is provided on the flange portion (A) on the apparatus main body side, the gasket loading is easy.
Since the head of the gasket protrudes toward the flange portion (B) of the opening / closing lid due to the configuration of the loading portion, when an external pressure is applied to the opening / closing lid, the gasket is compressed by the pressing force of the flange portion (B) to form a self-sealing. . At this time, the flat portion at the bottom of the gasket is received by the flat portion of the loading portion, and the lip portion is pushed and expanded in the groove portion for storing the lip, thereby improving the sealing property. Therefore, the gasket is not crushed.
In this case, no sealing air is applied.

Reference numeral 3 denotes an opening / closing lid, which has a flange portion (B) 4 provided on the periphery. Reference numeral 5 denotes a gasket, and a loading portion 6 of the flange portion 2.
And the head protrudes toward the flange portion 4 side. Reference numerals 7 and 8 denote lip portions provided on the inner and outer peripheral edges of the gasket bottom portion, and reference numeral 9 denotes a bottom flat portion. Reference numerals 10 and 11 denote grooves for accommodating the lip, which are provided on the inner and outer peripheral edges of the bottom of the loading section 6. Reference numeral 12 denotes a flat surface provided in a convex shape. Reference numeral 13 denotes a sealing air supply hole from which air is supplied from an air source. 14

実にする。In the above structure, when an external pressure is applied to the opening / closing lid 4, the gasket 5 is compressed by the pressing force of the flange portion (B) 4 to form a self-sealing. In this case, the bottom flat portion 9 of the gasket is brought into close contact with the convex flat portion of the loading portion so as to be squashed, and the lip portions 7 and 8 are pushed out to enhance the sealing performance. Also, when an internal pressure is applied, the bottom flat portion 9 and the lip portions 7 and 8 of the gasket 5 are expanded by the air pressure from the air source, thereby ensuring the sealing action.
