Abstract

PURPOSE:To improve the independent stability of a longish calcining antenna with a coil part by arranging an elastic body, which applies compressing force in an axial direction to the coil part, inside of the elastic coil material. CONSTITUTION:Coil 1 of the fixed winding diameter and length obtained by thickly winding a piano wire is provided and set metal fitting 2 provided with a fitting screw to a radio device is set in the lower end of coil 1. Then, a protruding piece with a hole for the hook of screw 3 is provided to set metal fitting 2 toward the inside of coil 1, and set metal fitting 4 similar to set metal fitting 2 except the fitting screw part is set to the upper end part of coil 1. Further, tension spring 3 which can be inserted into the coil 1 provided with hook parts at both sides is inserted into coil 1 and hooks at both the sides are set to set metal fittings 2 and 4. The contact force of coil 1 is energized by spring 3 equipped inside to obtain a long antenna with a small coil diameter.
