Claims

[Claims for Utility Model Registration] A waveguide that connects two waveguides 1A and 1B with a propagation mode matching converter 5 interposed between the two waveguides 1A and 1B with different propagation modes. In the connection structure, an axial through hole 6 is bored between the connecting flange 4 attached to the axial end of one waveguide 1A and the converter 5, and the connection is made through this through hole 6. The fitting 7 is connected and fixed to the connecting flange 4 of the converter 5, and a sealing mechanism 13 is provided in the gap between the converter side opening 6a of the through hole 6 and the connecting fitting 7, A waveguide connection structure characterized in that the connection flange 4, the periphery of the coupling end surface 15 between the transducer 5, and the flange side opening 6b of the through hole 6 are covered with a waterproof cover 16.
