In the structure using the conventional nut described above, the fixation of the adjustment screw is uncertain, so it is necessary to strengthen the fixing part with adhesive, etc., and when readjustment is required in the field, such as with an equalizer, for example. The disadvantage was that it was not suitable.
一方、他のねじにより調整ねじに対して横方向

生じるという欠点があつた。 On the other hand, in a structure in which other screws apply force to the adjustment screw from the side to fix it, the frequency increases because it depends on the frictional force at the point of contact between the other screws and the adjustment screw. When the size of the adjusting screw is reduced, there is a drawback that the distortion generated in the adjusting screw during fixing causes a change in the warming characteristics before and after fixing.

Next, the present invention will be explained by way of an embodiment with reference to the drawings. FIG. 1 is an exploded perspective view of an embodiment of the present invention, and FIG. 2 is a cross-sectional view of an adjustment screw fixing part. In these figures, a mount portion 3 for mounting the adjusting screw on the waveguide 1 is fixed to the outer surface of the waveguide 1 on which the adjusting screw 2 is attached. The adjusting screw 2 includes a knob portion 2a at the top, a fixed portion 2b in the middle that is fixed externally, and an adjusting portion 2c inserted into the waveguide 1. The mount part 3 has a cylindrical shape in which a hollow part 3a is formed, and an enlarged part 3b is formed in the middle part of the hollow part 3a, and the enlarged part 3b opens on the side surface of the mount part 3. A metal fitting 4 for fixing the adjusting screw 2 to the mount part 3 is formed to a size that can be inserted into the enlarged part 3b, and has a through hole 4a having an inner diameter larger than the outer diameter of the fixed part 2b of the adjusting screw 2. Horizontal screw 4b on the side
is fixed. A lock nut 6 is screwed onto the horizontal screw 4b.

緩めれば容易に再調整ができる。 The metal fitting 4 is inserted into the enlarged part 3b, and the adjusting screw 2 is inserted into the hollow part 3a of the mount part 3. At this time, the fixed part 2b of the adjusting screw 2 is fitted with a collar 5 having cushioning properties, so that the metal fitting 4 penetrates. It is inserted into the hole 4a together with the collar 5, and the adjustment part 2c at the tip is connected to the waveguide 1.
inserted at the optimal position. Once the position of the adjustment screw is determined, the lock nut 6 is rotated to move the metal fitting 4 and fix the adjustment screw 2 to the mount portion 3. At this time, the adjustment screw 2 is a collar 5 with cushioning properties.
Since it is fixed to the mount part 3 via the cushioning collar 5, the occurrence of distortion is greatly suppressed, and since the contact area receiving force is increased by the cushioning collar 5, changes in electrical characteristics when fixed are also suppressed. can. The adjustment screw 2 can be readjusted easily by loosening the lock nut 6.
