てアンテナが抜けたりする虞れがある。 When rotatably attaching an antenna to a portable radio cassette tape recorder, etc., each manufacturer tries to simplify the rotation mechanism of the antenna base as much as possible to improve workability and reduce costs. Japanese Utility Model Application No. 50-65340 discloses an antenna in which a small diameter portion of an antenna base fitting is rotatably held between a notch of a mounting angle and a receiving groove of a rib provided on the cabinet side. However, this device requires considerable dimensional accuracy in order to accurately match the mounting angle and the ribs. On the other hand, Japanese Utility Model Application Publication No. 47-35945 discloses a rod antenna in which the base of the rod antenna is inserted into a mounting hole formed in the cabinet, and a U-shaped stopper made of an elastic plate is fitted into the protrusion. There is. However, in this device, vertical wobbling is likely to occur, and there is also a risk that the clasp may come off and the antenna may come off.

る。 1 and 2 show an embodiment in which this invention is applied to a rod antenna 2. That is, in this antenna mounting device 1, a mounting shaft 4 formed to have a smaller diameter than the base 3 of the rod antenna 2 is integrally connected to the base 3. The mounting shaft 4 has an annular groove 5 bored in its peripheral wall, and a tapered wall 6 is provided at its lower edge. On the other hand, an antenna mounting hole 8 is bored in the housing 7 of a telecommunications device such as a radio to which the rod antenna 2 is mounted. The upper part is a stepped hole with an enlarged diameter so that each can fit properly. The annular groove 5 is provided at a position where it is substantially flush with the inner opening edge of the antenna mounting hole 8 when the mounting shaft 4 is inserted into the antenna mounting hole 8. In this example,
A guide groove 9 is bored in the side wall of the housing 7 at the part where it intersects with the upper wall, and a boss 10 is provided below the guide groove 9, and the tip of the boss 10 is connected to the mounting shaft 4. It is located slightly below the lower end of the protrusion. In addition, this antenna mounting device 1
is equipped with a holding plate 11 for rotatably holding the mounting shaft 4 in the housing 7. This holding plate 1
1 is a conductive material such as phosphor bronze bent into an approximately L shape, as illustrated in FIG.
It is preferably made of a material having appropriate spring elasticity, and one piece 11a has a through hole 12 through which the mounting shaft 4 is inserted, and the other piece 11a has a through hole 12 through which the mounting shaft 4 is inserted.
1b is formed to be slightly longer than the protrusion of the mounting shaft 4, and a screw hole 13 is provided at the end thereof.
The holding plate 11 is inserted into the guide groove 9 of the housing 7 with the end of the piece 11a inserted into the through hole 12.
The mounting shaft 4 protruding from the antenna mounting hole 8 is inserted into the antenna mounting hole 8 . The other piece 11b of the holding plate 11 is fastened to the tip of the boss 10 by a screw 14 through a screw hole 13. At this time, the other piece 11b is pressed against the tapered wall 6 of the mounting shaft 4 and bent, and as a result, the other piece 11a slides along the guide groove 9 so as to be pulled leftward in FIG. The peripheral edge of the hole 12 is firmly engaged with the annular groove 5.

こともできる。 In the above configuration, the rod antenna 2 is
It is rotatable around a mounting shaft 4 connected to the base 3, and the through hole 12 of the holding plate 11 is located in the annular groove 5.
Since the peripheral edges are engaged, it is prevented from coming off, and since the other piece 11b of the holding plate 11 is pressed against the tapered wall 6, there is no wobbling and an appropriate frictional force is applied when the rod antenna 2 rotates. There is. Further, since sufficient contact is made between the holding plate 11 and the mounting shaft 4, a lead wire can be soldered to the end of the other piece 11b of the holding plate 11 as an antenna terminal.

なお、この考案は、前記した実施例に限定され
