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 3):
The shutter according to  claim 1 , wherein:\n a long hole extending in the moving direction of the second member is formed in one of the first member and the second member, while a convex portion inserted into the long hole is formed in another one of the first member and the second member; the convex portion is in contact with one end of the long hole in a state that the small aperture is closed by the second member, while the convex portion is in contact with another end of the long hole in a state that the small aperture is opened by the second member; and the driving section closes the aperture by moving the first member by moving the second member in a direction for closing the small aperture beyond a position where the convex portion is in contact with the one end of the long hole, and the driving section opens the aperture by moving the first member by moving the second member in a direction for opening the small aperture beyond a position where that the convex portion is in contact with the other end of the long hole.
