Abstract:
An attachment structure of a gasket for a refrigerant-seal, comprising:a first connection member having a first opposite surface opposite to one side surface of the gasket, and a first wall surface opposite to one end surface of the gasket; and a second connection member having a second opposite surface opposite to the other side surface of the gasket, and a second wall surface opposite to the other end surface of the gasket, wherein: the first and second connection members are disposed to define a seal space by the first and second opposite surfaces and the first and second wall surfaces; the gasket is constructed by a metal portion and a film coating layer provided on both side surfaces of the metal portion in a thickness direction to have a deformation portion deformable in the thickness direction; the gasket is disposed in the seal space in such a manner that the one end surface of the gasket contacts the first wall surface and the other end surface of the gasket is separated from the second wall surface by a predetermined clearance, before the first and second connection members are fastened; and the gasket extends in an extension direction approximately perpendicular to the thickness direction, and the other end surface of the gasket press-contacts the second wall surface, after the first and second connection members are fastened.
