Abstract:
A shutter moves along a surface of a partition wall provided between two spaces different in pressure, which faces the space higher in pressure, to open and close an aperture formed on the partition wall with an amount of force smaller than conventional shutters require. The shutter includes: a plate-shaped first member arranged in a manner of moving along a surface of the partition wall, which faces one of the two spaces higher in pressure, to open and close the aperture, the first member being provided, in a region which corresponds to the aperture, with a small aperture having an area smaller than the area of the aperture, and a plate-shaped second member arranged in a manner of moving along a surface of the first member, which faces the space higher in pressure, to open and close the small aperture.

Claim (Index 7):
The shutter mechanism according to  claim 6 , wherein\n the operation member of one of the two shutters includes an extendable member extendable in a direction along which the shutter moves, and a restriction member that restricts extension of the extendable member to a predetermined distance.
