Abstract
The present invention includes an antenna rod, an antenna base which attaches the antenna rod so as to be capable of swiveling, a joint assembly which consists of a cylindrical member in an axial direction orthogonal to an axial direction of the rod at one end of the antenna rod, a pair of pivotal support portions provided so as to confront an upper portion of the antenna base so as to mount the joint assembly on a pivot in a swiveling manner, and a torsion spring which is provided with respect to the joint assembly and automatically returns the joint assembly to a predetermined swiveling position by giving the elasticity of itself even if a swiveling position of the joint assembly is changed due to an external force applied to the antenna rod.
