な接触状態が得られなかつた。BACKGROUND ART Conventionally, as shown in FIG. 1, a plan view and a cross-sectional view of the coupling portion of a waveguide, an electric contact gasket 2 is sandwiched between two opposing flat flanges 1 and 5. It is tightened with outer circumferential connection bolts 6. In this case, the gasket 2 is provided with a rubber packing 3 to ensure waterproofing and airtightness and a gasket contact part 4 to ensure electrical connection along the rectangular waveguide opening, but the Since the tightening is done only with the outer circumferential coupling bolt 6, the coupling bolt 6 is used for the long side of the waveguide mouth.
Since the distance between the rubber packing 3 and the gasket contact portion 4 becomes large, uniform and complete contact with the rubber packing 3 and the gasket contact portion 4 cannot be obtained at this portion.

けることができるものである。 According to the present invention, as described above, the opposing flat flanges are connected via the electrical contact type gasket to the conventional peripheral coupling bolt for mechanically stabilizing the coupling, and the newly provided electrical contact. Since it is uniformly tightened with a connecting bolt near the pipe port to ensure reliability near the pipe port, excellent electrical contact can be obtained and power durability is improved. In the present invention, since the flat flange is approximately circular and the waveguide is rectangular, coupling bolts can be provided near the pipe opening in addition to the outer periphery of the flange.

By tightening the bolt 6 and the connecting bolt 8 near the pipe opening, a uniform contact state is obtained between the rubber packing 3 and the gasket contact portion 4 arranged along the rectangular pipe opening, and arcs etc. are prevented from forming in the minute gap. It is possible to obtain a bonded state with excellent power durability and no generation.
