PROBLEM TO BE SOLVED: To provide a support mechanism for an antenna with high reliability that conductivity between an antenna main body and a radio equipment and friction damping of a rotary mechanism are excellent. SOLUTION: A resin-made stator side hinge 7 fixed to a main body of a radio equipment 1 and a resin-made rotor side hinge 6 fixed to a base end of an antenna main body 4 are formed, a groove 15 is formed at a tip of a projection bearing section 14 in the stator side hinge 7 and a notch 10a formed to a cylindrical part 10 at a tip of the rotor side hinge 6 is fitted to a bearing section 14 of the stator side hinge 7, a rotary shaft 24 fixed to both sides of the cylinder 10 of the rotor side hinge 6 is supported to the bearing section 14 freely turnably, metal-made terminal 17 is built in the rotor side hinge 6 and connects to a male screw 22 of the antenna main body 4 screwed to the rotor side hinge 6 electrically and a conductor wire 20 of the terminal 17 is placed in the groove 15.
