PROBLEM TO BE SOLVED: To provide an antenna structure with excellent bending performance and excellent assembling workability. SOLUTION: The antenna structure is disclosed, wherein a thin rod member made of a conductive metal is disposed in a spring pipe 10 made of a conductive metal in a freely retractable and containable way to restrict the rod member from coming off from the spring pipe 10. A metallic sleeve 30 having an inner diameter fittable to the outer peripheral of the tip of the spring pipe 10 to restrict the rod member 12 from coming off from the spring pipe 10 is inserted to the spring pipe 10 and a flexible tube 32 to which the tip of the spring pipe 10 is inserted is formed of a resin. The spring pipe 10 is inserted to the flexible tube 32 and the tip of the spring pipe 10 is fitted to the metallic sleeve 30, and the metallic sleeve 30 is caulked and fixed to the spring pipe 10. A range wherein only the flexible tube 32 is provided at the outer peripheral of the spring pipe 10 is extended to provide excellent bending performance. Further, since fixing only by caulking is adopted, no adhesive member is required to provide ease of working. COPYRIGHT: (C)2005,JPO&NCIPI
