Claims

[Claims for Utility Model Registration] A coaxial tube is connected to a first waveguide, a housing is connected to a second waveguide, and the coaxial tube is inserted into a cylindrical hole formed in the housing via a bearing. In the rotary joint of waveguides that are connected and have a chiyoke circuit formed on the inner wall of the cylindrical hole, a cylindrical bearing made of dielectric material is used as the bearing, and the housing is divided in the diametrical direction of the cylindrical hole. What is claimed is: 1. A rotary joint for a waveguide, characterized in that a concave portion constituting a bearing seat and a chain yoke circuit is formed in the divided surface of the housing.
