治具を必要とする。In the case of the conventional adhesive joint structure of the waveguide and the flange as described above, in the case of the conventional example of FIG. 9, there is a fit structure between the outer surface of the waveguide and the inner surface of the flange, which is the adhesive joint portion by the adhesive, and a clearance is provided. It is small, and when the waveguide (1) is inserted into the flange (2), the adhesive applied to the joint in advance is scraped off, so it is not possible to apply an appropriate amount of adhesive to the joint. Further, it is difficult to form an adhesive layer having a uniform thickness, and the required mechanical bonding strength cannot be obtained. Reinforcement by spot welding is performed when particularly strong joint strength is required, but this requires additional man-hours. If a large clearance is provided between the outer surface of the waveguide and the inner surface of the flange and an appropriate amount of adhesive is applied to the joint to form an adhesive layer with a uniform thickness, the predetermined waveguide and flange A special jig is required to obtain the assembly dimensional accuracy of.

Since the adhesive bonding area of the step portion (6) of the flange end portion, which is the adhesive joint portion, is limited to be small and only the end portion is bonded at one end, the required bonding strength cannot be obtained. Further, if the axial dimension of the step portion (6) is increased in order to increase the joint strength, the fitting portion is only at one end, so a special jig is required to obtain a predetermined waveguide and flange assembly dimension accuracy. To do.
