Claims

[Scope of utility model registration request]

In a tightening structure for joining and tightening flanges of a waveguide, a concave-convex fitting part and a socket pin for positioning are provided at the joining part of the flanges, and a screw cap is attached to the threaded part provided on the outer peripheral surface of one flange. A structure for tightening the flange part of a waveguide, which has a structure in which the flange part is tightened by screwing together, and is characterized by improving the contact surface of the flange surface, preventing the screw cap from loosening, and making it possible to adjust the rotation by a small amount.
