Patent ID: 7942165

Claim:
A connecting structure for an integration panel and a fluid device, wherein, when a first fluid supply/discharge port portion of an integration panel having said first fluid supply/discharge port portion where pipe-like fluid passages are opened, and a second fluid supply/discharge port portion of a fluid device having said second fluid supply/discharge port portion where pipe-like fluid passages are opened are to be communicatingly connected to each other in a state where said fluid passages are sealed by a ring-like gasket interposed between said first fluid supply/discharge port portion and said second fluid supply/discharge port portion, in said first fluid supply/discharge port portion and said second fluid supply/discharge port portion, annular projections are formed on outer-diameter portions of said fluid passages which are opened in end faces, said gasket is configured by a flexible material having: a fluid path which is formed to allow said corresponding fluid passages of said first and second fluid supply/discharge port portions to communicate with each other; a pair of annular grooves which are formed on an outer-diameter portion of said fluid path to be fitted respectively to said annular projections formed on said end faces of said first and second fluid supply/discharge port portions; and inner and outer peripheral wall end portions which are projected in an axial direction of said first and second fluid supply/discharge port portions in order to form said annular grooves, annular press portions which are buttable against said peripheral wall end portion on said inner-diameter side are formed on inner-diameter sides of said annular projections on said end faces of said first and second fluid supply/discharge port portions, said annular press portions are formed into forward-narrowed annular projections having tapered peripheral faces in which side peripheral faces on sides of said annular projections are inclined so that valley portions surrounded by said annular press portions and said annular projections have an inward-narrowed shape, said peripheral wall end portion on the inner-diameter side is formed into a forward-narrowed annular projection which has a tapered peripheral face butting against said tapered peripheral faces of said annular press portions, and which is enterable into said valley portions, said first fluid supply/discharge port portion and said second fluid supply/discharge port portion are attracted to each other via said gasket, whereby said annular projection of said first fluid supply/discharge port portion and said annular groove of one end of said gasket, and said annular projection of said second fluid supply/discharge port portion and said annular groove of an-other end of said gasket are fitted respectively to each other, and said tapered peripheral faces of said annular press portions are press contacted with said tapered peripheral face of said peripheral wall end portion on the inner-diameter side to form a sealing portion.
