なるという欠点があつた。 Conventionally, both side walls of the cut groove are pivotally connected to a mounting plate inserted into a cut groove provided in the base metal fitting of a rod antenna element having a telescopic multi-stage pole, using a pivot shaft.
Antenna devices are generally used in which the mounting plate is fixed to a member to be mounted, such as a housing of a radio, with screws or the like. However, in such an antenna device, the antenna element is bent in one direction, that is, the direction in which the antenna element is bent is in one direction, and there are also known antenna devices in which the antenna element is bent in two mutually orthogonal directions. Conventional rod antenna devices, in which the antenna element is bent in two directions, have a complicated structure, require many man-hours to process, and are expensive.

On the other hand, as shown in FIG. 3, in the center of the mounting band 5 made of an elastic material such as a metal plate, the width of which is slightly narrower than the width of the groove 2, there is an arcuate portion 5a that is longer in the circumferential direction than a semicircle. This arcuate portion 5
a is fitted onto the mounting shaft 3 and elastically clamps it, and both ends 5b of the mounting band 5 protrude upward from the circular arc portion 5a of the mounting band 5, facing each other. It extends upward from the attached member 1. Correspondingly, a base metal fitting 8 is fitted and fixed to the base end of the base pole 7 of the rod antenna element 6 equipped with a telescopic multi-stage pole, and both ends of the mounting band 5 are fitted into the cut grooves 8a formed in the base metal fitting 8. 5b is inserted. And these both ends 5b are
A spring 9 such as a spring washer interposed between these is pressed against the inner surface of both side walls 8b of the cut groove 8a of the base metal fitting 8, and the both side walls 8b, both ends 5b of the mounting band 5, and the spring 9 are connected in series. The base metal fitting 8 is rotatably attached to the mounting band 5 by a pivot shaft 10 formed of a penetrating roll pin, and the pivot shaft 10 is disposed in a horizontal direction orthogonal to the mounting shaft 3.

う効果がある。 As explained above, the antenna device of the present invention uses one mounting band, the arc-shaped part of this mounting band is fitted and held by the mounting shaft provided on the mounted member, and the mounted member is removed from the arc-shaped part. Both ends of the mounting band extending from the rod antenna element were inserted into the cut grooves of the base metal fitting of the rod antenna element, and the side walls were pressed into contact with the spring. Although the antenna element can be bent in two mutually orthogonal directions due to the pivot axes being orthogonal to each other, the number of parts is relatively small, and the processing of each member such as the mounting band is easy. It is easy to use, and the antenna element may be a common one, so it can be provided at a low price. Moreover, in the antenna device of the present invention, by fitting and holding the circular arc portion of the mounting band on the mounting shaft, rotational frictional force can be obtained between them, and the elastic return force of the mounting band and its both ends can be generated. Since the rotational friction force between the side wall of the cut groove of the base metal fitting and both ends of the mounting band is obtained by the spring force of the interposed spring, the two ends can be easily perpendicular to each other with a simple structure.
This has the effect that the rotational torque in the direction can be made appropriate.
