Claims

[Scope of utility model registration request]

First and second flanges, each of which is a plate-like body, each having a through-hole serving as a waveguide, a thin insulator flat plate, and the through-holes coaxially connected to each other via the insulator flat plate. A waveguide hermetic coupling structure comprising means for integrally fixing both the flanges and the insulator flat plate in a facing positional relationship,
An annular chain groove that surrounds the opening of the through hole and an annular gasket groove that surrounds the chain groove are formed on the plate surface of the first flange that is in close contact with the insulator flat plate, An annular gasket groove that surrounds the opening of the through hole is formed on the plate surface of the second flange that is in close contact with the insulator flat plate, and the gasket groove of the first flange and the second flange are connected to each other. A waveguide hermetic coupling structure characterized in that first and second gaskets are respectively engaged with the gasket grooves of the waveguide.
