することができる。The screws 5 installed in this way are connected to the opposing parts 6a and 6.
b are pulled apart by the spring force of the spring plate 6, and the gaps between the threaded part 5b and the screw hole 3a of the shield plate 3 and between the threaded part 5b and the screw hole 6e of the spring plate 6 are pulled apart. As soon as the screw play is eliminated, the spring force of the opposing part 6b of the spring plate 6 to return causes the other opposing part 6a to come into close contact with one surface of the shield plate 3, and in this state, screw in the screw 5 and unscrew it. For example, while maintaining the above relationship, the resonant frequency can be adjusted by moving the screw 5 closer to or farther away from the line 4.

好であるなどの実用的な効果を有する。That is, according to the present invention, one opposing portion 6a of the U-shaped spring plate 6 made of a metal plate is provided with a hole 6d, and the other opposing portion 6b is provided with a screw hole 6e. 6 a
, 6b are placed on different sides of the shield plate 3, and the metal screws 5 are inserted into the shield plate 3 through the hole 6d.
The screw 5 is screwed into the screw hole 3a of the shield plate 6 and the screw hole 6e of the facing part 6b of the spring plate 6, and the screw 5 is always pulled by the spring plate 6. The screw hole 3a and the screw hole 6e of the spring plate 6 are securely screwed together, and the screw 5 can be securely held without shifting due to vibrations, shocks, etc.
Further, the conduction between the screw 5 and the shield plate 3 is established through the contact between the screw portion 5b and the screw hole 3a of the shield plate 3 and the engagement between the screw portion 5b and the screw hole 6e of the spring plate 6 at the opposing portion 6a of the spring plate 6. Since this is done by contacting the shield plate 3 with the screw 5, the conductivity is good, and there is no fear of fluctuations in high frequency power due to unstable contact. Screw hole 3a of spring plate 6
, 5e, which has practical effects such as good productivity.
なお、ネジ５の取付けたシールド板３に限定されず、枠
体１でもよく、要は取付板でよいこと勿論である。In addition, it is not limited to the shield plate 3 to which the screws 5 are attached, and the frame body 1 may be used, and it is of course possible to use a mounting plate.
