Abstract
Provided is a valvewhich requires only a small space for the open/close operation of an openingin a partition wall. A sealing partincludes a sealing memberfor sealing the opening by being pressed onto the partition wall around the opening. An urging meansurges the sealing memberagainst the opening when the sealing memberis in contact with the opening. A driving meansgenerates a driving force orthogonal to an opening central axis A which is an axis perpendicular to a partition plateand passing through the center of the opening. A linkage, which is a Scott Russell linkage connecting the sealing partand the driving means, converts the driving force of the driving meansinto a driving force which is parallel to the opening central axis A and makes the sealing partmove along the same axis.
