Abstract
A connecting structure for an integration panel and a fluid device which, in order to promote integration of fluid pipes, can be further compactified is provided. In a concentric double flow path type connecting structure, an integration panel 1 and a valve 2 are connected to each other in a sealed state via inner and outer annular gaskets G1, G2 while pipe-like fluid passages 3a, 7 and annular fluid passages 4a, 8 are concentrically arranged. Annular projections 11, 21, 31, 41 are formed on fluid supply/discharge port portions 1A, 2A made of a fluororesin, and annular grooves 51, 61 are formed in the gaskets G1, G2 made of a fluororesin. A joined state where the annular projections and the annular grooves are fitted to each other to form a fitting sealing portion 10 is held by holding means I for attracting together the fluid supply/discharge port portions 1A, 2A and maintaining the attraction. The inner first gasket G1 is configured as a multifunctional intermediate gasket in which the inner peripheral face 54a functions also as the outer walls of the pipe-like fluid passages 3a, 7, and the outer peripheral face 55a functions also as the inner walls of the annular fluid passages 4a, 8.
