PROBLEM TO BE SOLVED: To provide a coupling structure which is used at a low cost. SOLUTION: In the coupling structure of a flow passage for flowing refrigerant and absorption solution of the absorption refrigeration cycle 10, a gasket 27, enclosing a shaft 31, used for this coupling structure, has a protruding rod part 32 for pressing coupling surfaces 22, 25 by elastically deforming when clamped by two coupling members 23, 26. As a result, the protruding rod part 32 presses the coupling surfaces 22, 25 and leakage of fluid is prevented. By using a gasket arranged with the protruding rod part 32, leakage of the fluid is prevented and the protruding part 32 is mounted by using an inexpensive means for pressing a metal plate.
