A hermetic enclosure having an air pressure adjustable function, which can adjust inside air pressure of the hermetic enclosure, is provided. In order to prevent devices in the hermetic enclosure from corroding, the hermetic enclosure having an air pressure adjustable function provides a main body having a clearance part and a packing fixing groove, a door, and packing that is fixed to the packing fixing groove of the main body. And the door is jointed with the main body by placing the packing between the door and the main body in a state that the door is able to slide on the packing. And when inside and outside air pressure of the hermetic enclosure becomes different, the door moves on the packing and the clearance part of the main body is changed, and the inside and outside air pressure is adjusted to be almost equal.
A hermetic enclosure having an air pressure adjustable function, which changes the volume of a hermetic enclosure so that inside air pressure of said hermetic enclosure is made to be almost equal to outside air pressure when said inside air pressure of said hermetic enclosure is different from said outside air pressure.
A hermetic enclosure having an air pressure adjustable function, in which a main body of said hermetic enclosure or a door of said hermetic enclosure is movable, and which moves said main body or said door of said hermetic enclosure so that the volume of said hermetic enclosure is changed.
