(see FIG. 10) and is fixed to the casing 2 by screwing into the screw hole 13 formed on the end surface of the casing 2. Furthermore, a screw hole 14 is formed in the flange 6, and this is used to connect the input/output waveguide (standard waveguide).
flange (not shown) is connected to flange 6. As a result, the cut-off waveguide section constituted by the housing 5 constitutes a wave device.

It is becoming possible to do this.
上記のような本考案による遮断導波管部の構造
には以下のような長所がある。 The structure of the blocking waveguide section according to the present invention as described above has the following advantages.

なうことが可能である。(1) First, the casing that constitutes the cut-off waveguide section is separable from the input/output waveguide (standard waveguide), and has a base section that is the resonator fixing section and a lid section that serves as the lid. Since the resonators can be divided into two, it is very easy to arrange and fix the resonators. In particular, since the splitting surface of the housing is separated from the resonator fixing inner wall surface and a slightly high stepped section is formed at the housing base, this stepped inner wall surface can be used to accurately position the resonator. Is possible.
(2) また筐体の分割面は共振器の電界面（Ｅ面）

付けにも何んら支障がなく、好都合である。(2) Also, the dividing surface of the housing is the electric surface (E surface) of the resonator.
and the separation distance from the resonator fixing plane is smaller than the thickness of the resonator fixing spacer, so the dividing plane of the housing is located outside the area that has a significant effect on the magnetic field coupling of the resonator. In this case, it is possible to minimize or almost ignore the adverse effects of the divided structure on the waveform characteristics, and it is possible to obtain good characteristics. Further, such a position of the dividing plane does not pose any problem in attaching the frequency adjustment screw, which is convenient.

非常に簡便なものとなる。 Furthermore, the structure in which flanges 6 having standard waveguide openings are provided at both ends of the housing 5 as in the illustrated embodiment has the following additional advantages. First, all interfaces can be performed using standard waveguides. In addition, as shown in FIG. 10, the flange 6
If the housing cover 5B is left fixed to the housing base 5A with the screws 12, and the housing cover 5B is made removable by removing the screws 9 and 12, testing and adjustment of the corrugator becomes very simple.

取付けが可能である。 The flange 6 in the illustrated embodiment has almost the same external dimensions as the housing 5, and the bolts for fixing the flange on the input/output waveguide side are screwed into the screw holes 14 (FIG. 5). If the mating flange is large in size, the flange 6 can be replaced with a larger one to accommodate the larger flange, allowing for attachment using bolts and nuts. Further, even in the case of a flange having the dimensions shown in the illustrated example, it is possible to attach the flange with bolts and nuts by cutting out the corner portion corresponding to the flange screw hole 14 of the housing 5 (not shown).
