る。By the way, of the conventional examples, the former one has a complicated rotary ball type support mechanism and a large number of parts, so that the diameter dimension of that part becomes large and the weight also increases. Therefore, it is not possible to mount it on a set where the antenna installation space has become extremely narrow, such as a multifunctional ultra-compact LCD TV that incorporates a radio in addition to the recent TV. There is a problem that does not match. Also, in the latter conventional example, the structure is simple and the number of parts is small, but the lubricant such as grease applied to the rotating friction surface between the shaft portion of the base metal fitting and the cylinder portion of the mounting metal easily flows out, and the set is soiled, There is a problem that sufficient rotation torque cannot be maintained for a long time. Therefore, the present invention provides a rod antenna device that has a small number of parts, can be made compact and lightweight, and is suitable for an ultra-compact set, but can keep a sufficient rotational torque for a long period of time without polluting the set device. With the goal.

回転トルクが長期間保持される。Hereinafter, an embodiment of the present invention will be specifically described with reference to the drawings. In FIG. 1, reference numeral 1 is an antenna element of a rod antenna fitted in a telescopic multi-stage, 2 is a base metal fitting fitted to the base end of the telescopic multi-stage antenna element 1 and caulked and fixed, 3 is this base metal. 2 is pivotally attached with a predetermined rotational torque to support the telescopic multi-stage antenna element 1 so as to be able to move up and down, and 4 is the vertical direction of the equipment for mounting the telescopic multi-stage antenna element 1 via the base metal 3. Each of the mounting brackets that rotatably supports the shaft is shown. As shown in FIG. 2, the base metal fitting 3 has a holding groove 3a for pivotally mounting the mounting piece 2a of the base metal fitting 2 at one end, and a mounting metal fitting 4 described later at the other end. The stepped shaft portion 3b has a matching stepped shaft portion 3b, and an annular groove 3c for oil sump is formed in the small diameter portion of the stepped shaft portion 3b, and a collar is formed at the center in the longitudinal direction.
3d is formed. On the other hand, as shown in FIGS. 3 and 4, the mounting metal fitting 4 has a cylindrical portion 4b having a stepped hole 4a into which the stepped shaft portion 3b of the base metal fitting 3 is fitted, and an outer circumference of the cylindrical portion 4b. And a mounting piece 4c extending in the tangential direction from the mounting portion 4c, a screw hole 4d for mounting to a set device using an antenna is formed in the mounting piece 4c, and the tubular portion 4b imparts a radial elastic force to the screw portion 4d. Axial and lateral slit grooves 4e, 4f for forming are formed. The axial slitting groove 4e is a vertical slitting groove that opens only on the lower end side of the tubular portion 4b corresponding to the tip end side of the stepped shaft portion 3b of the base metal fitting 3, and the horizontal slitting groove 4f is It is a lateral split groove that intersects with the axial slit groove 4e in the vicinity of its closed end. Then, the stepped shaft portion 3b of the base metal fitting 3 is rotatably press-fitted by applying a lubricant such as grease to the stepped hole 4a of the cylindrical portion 4b having the slit grooves 4e and 4f. As shown in FIG. 5, the outer periphery of the tubular portion 4b is prevented from being pulled out and covers the opening portion at the lower end of the tubular portion and the opening portions of the slit grooves 4e and 4f formed in the tubular portion 4b. The coating film 5 is made of an elastic resin such as clear lacquer or silicone rubber. In the above configuration, by mounting the mounting piece 4c of the mounting bracket 4 to a set device such as a micro liquid crystal television with a radio, the expandable multi-stage antenna element 1 is rotated around the vertical axis through the base metal 3 with respect to the set device. Is rotatably supported by
It is supported so that it can be tilted up and down via the base metal fitting 2. Here, the tubular portion 4b of the mounting member 4 has the opening at the lower end thereof and the opening portions of the slit grooves 4e, 4f covered with the resin coating film 5, so that the lubricant such as grease can be applied to the tubular portion 4b. It does not collect in the stepped hole 4a and flow out to the outside, and thus the set device is not polluted. On the other hand, since the resin coating film 5 has elasticity, the cylindrical portion 4b of the mounting bracket 4 elastically returns in the direction of diameter reduction by the slit grooves 4e and 4f, and is attached to the stepped shaft portion 3b of the base bracket 3. Elastic contact from the radial direction. Therefore, in the state in which seizure is prevented by a lubricant such as grease, the expandable multi-stage antenna element 1 retains sufficient rotational torque for a long period of time. Even if the expandable multi-stage antenna element 1 is bent or an impact force is applied to the tubular portion 4b of the mounting bracket 4, the resin coating film 5 absorbs the impact due to its elasticity, so that the tubular portion 4 is plastic. From this point as well, the predetermined rotation torque is maintained for a long time without being deformed.

き、超小型のセットにも適合する。As described above, according to the present invention, the lubricant such as grease to be interposed between the shaft portion of the base metal fitting and the tubular portion of the mounting metal fitting is
Since the resin coating film covers the lower end opening of the cylinder and the openings of the axial and lateral slit grooves formed in the cylinder to prevent outflow to the outside, mount the rod antenna device. Does not pollute set equipment. In addition to preventing the lubricant from flowing out,
Since the resin that forms the coating film has elasticity, the cylindrical part of the mounting bracket elastically expands in diameter due to the slit groove, and the restoring force makes elastic contact with the shaft part of the mounting bracket from the radial direction. The antenna element can retain a sufficient rotation torque for a long period of time. Moreover, since the number of components is small, it can be made smaller and lighter, and is suitable for ultra-small sets.
