PURPOSE:To improve the mounting strength of an antenna and the electrostatic dielectric strength by covering a base of the antenna with an elastic plastic case and providing a cylindrical rib to the antenna mounting part of a case. CONSTITUTION:A plastic 13 is sheathed to a flexible wire 12 in the antenna 11 and the base is covered by an elastic plastic case 14. A cylindrical rib 16 to surround the base of the plastic case 14 of the antenna 11 is provided to the antenna mounting part and the antenna 11 is mounted by a mounting screw 17. Thus, the mounting strength of the antenna is improved to support the base of the plastic case 14 of the antenna 11 by the rib 16 in this way and the rib 16 offers a longer creeping distance from the outside of the case to the metallic part in the inside of the case thereby improving the electrostatic dielectric strength.
