WIPO Patent Application WO/2007/007507

A1

A connection structure of a stack panel to a fluid device capable of maintaining excellent sealability without almost performing further tightening and improving assemblability. The stack panel (1) is communicably connected to a valve (2) through an annular gasket (G) in such a state that a single cylindrical fluid passage (3, 7) is sealed. Annular projections (11) and (21) are formed at first and second fluid inlet and outlet parts (1A) and (2A), and the gasket (G) is formed of a fluororesin and comprises a pair of annular grooves (51) and (51) formed in the outer diameter portion of a fluid route (W) to be fitted to the annular projections (11) and (21). The stack panel (1) and the valve (2) are pulled to each other and the annular projections (11) and (21) of the first and second fluid inlet and outlet parts (1A) and (2A) are fitted to the annular grooves (51) of the gasket (G) to form a fitted seal part. The connection structure further comprises a maintaining means (I) for maintaining the connected state of the stack panel to the valve.
