According to FIG. 3, the accommodating groove 23 is disposed in the longitudinal direction at one corner of the terminal body 10. However, although not shown, it is also possible to be arranged in the transverse direction of the terminal body 10 otherwise. In this case, the length or number of sub-rods 31 can be adjusted to secure the required antenna length.

4 is a front view of the antenna device of FIG. 3, and FIG. 5 is a front view showing a state in which the antenna device of FIG. 4 is drawn out.

4 and 5, the antenna device 20 includes a support rod 40 connected to the lower end of the antenna rod assembly 30. The upper end of the support rod 40 and the lower end of the antenna rod assembly 30 are rotatably connected about a second axis y by a pin 50.

The support rod 40 and the antenna rod assembly 30 are installed to be restrained by the guide member 22 fixed to the terminal body 10. The guide member 22 may be configured to receive a signal received by the antenna rod assembly 30 in a state before the antenna rod assembly 30 is drawn out and to be connected to the terminal body 10.

For example, before the antenna rod assembly 30 is pulled out, the radio wave may be received through the length from the guide member 22 to the support rod 40 (FIG. 4). When the antenna rod assembly 30 is drawn out, it is possible to receive radio waves through the length from the guide member 22 to the end of the antenna rod assembly 30, in which case the antenna rod assembly 30 is supported by the support rod 40. It is possible to rotate about the second axis (y) with respect to.

6 is a cross-sectional view illustrating the elastic providing part of the antenna device of FIG. 4, wherein the antenna device 20 is installed in the antenna rod assembly 30 and the support rod 40 such that the antenna rod assembly 30 is mounted on the support rod 40.
