In TV antennas, etc., a feeding part is used and a radiator is inserted into the feeding part, and a radiator is inserted into it. It is necessary to form a sufficient sealing state at A material is tightly covered between the insertion hole and the proximal end of the reflector, but in such conventional methods, it is necessary to specially prepare a tube-shaped elastic material. At the same time, a tube material with sufficient elasticity to form a tight sealing relationship when inserting and removing the reflector is inserted into one of the members, and the part of the tube material to be covered with the other member is inserted into the other member. Since the curved and overlapped part is returned to the other fitted member and covered, the handling operation becomes extremely complicated.

To explain the specific embodiment shown in the attached drawings, a box-shaped power supply part 1 is attached to a base 10, and a rod-shaped insertion part 11 is attached to a tubular insertion part 11 protruding from the power supply part 1. As shown in Fig. 1, the radiators 12, 12 are inserted, and the waveguide element 3 and reflector 4 are attached to the base rod 10 in front and behind, in addition to the above-mentioned feeding section. However, in the present invention, as shown in FIG. 2, the insertion part 11 for attaching the radiator 12 as described above is formed with an extension part 13 whose thickness is gradually thinner on the tip side. The inner diameter d 2 of the fitting part 11 is made smaller than the inner diameter d 1 of the fitting part 11 which approximately matches the outer diameter of the radiator 12, and in the illustrated embodiment, such an extension part 13 and A recessed groove 14 is disposed at the boundary of the insertion part 11. That is, the mounting condition of the radiator 12 according to the present invention as described above is as shown in FIG.
The base end of the radiator 12 as described above is inserted, and the connecting fitting 7 for a power supply circuit or a power supply line is attached and fixed to the power supply part 1. Since the extending portion 13 with a small inner diameter d2 is thin as described above, it has appropriate flexibility or elasticity, and the peripheral surface of the proximal end of the inserted radiator 12. The extended portion 13, which was in the state shown by the imaginary line in FIG. 3, is expanded in diameter as shown by the solid line, and an accurate waterproof state can be formed.

ており、実用上その効果の大きい考案である。 According to the present invention as described above, the extending portion 13 of the insertion portion 11 formed integrally with the power feeding portion 1 is gradually thinned, and its inner diameter d 2 is smaller than the inner diameter d 1 of the insertion portion 11. This makes it possible to form a favorable waterproof seal relationship with the inserted radiator 12, and its structure is simple, with a rubber material or the like used for special sealing. It does not require a tube-shaped elastic material, and its insertion/removal and other handling operations are extremely simple, making it a highly effective device in practical terms.
