Bobbin for bar antenna, antenna and door handle for a vehicle
First Claim
1. A bobbin for a bar antenna comprising a core supporting portion into which a bar shaped ferromagnetic core is inserted and supported, the core supporting portion being attached to at least one end of the bar antenna formed by the bar shaped ferromagnetic core around which a conductive wire material is wound, a conductive wire material fixing portion for fixing the conductive wire material and a core holding portion for sandwiching the bar shaped ferromagnetic core inserted into the core supporting portion from opposing both sides and firmly pressing by a tension force of the conductive wire material wound thereon.
