<p><P>PROBLEM TO BE SOLVED: To improve a connection structure for fluid devices comprised of a comparatively soft material such as synthetic resin so as to maintain effective tightening torque throughout a long period of time without causing looseness, backlash, and creeping, by further modifying a tightening and connecting means using a bolt/nut. <P>SOLUTION: The connection structure is composed such that a joined state of communicating and connecting a first fluid supply and a discharge opening 1A and a second fluid supply and discharge opening 2A via a gasket G can be maintained by carrying out the screwing and tightening of the bolt 66 passed through one 2 of the first or second fluid device 1, 2, and the nut 67 provided in the other 1 of the first or second fluid device 1, 2. The nut 67 is composed of a round bar fit to the other in a direction orthogonal to the axis p1 direction of the bolt 66, and in the other 1, a hole 1b is formed for making the bolt 66 pass through a fit-in part 70 of the nut 67 from a connecting face 1a with the one 2. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
