PROBLEM TO BE SOLVED: To improve an assembling workability by suppressing the increase of manufacturing cost in indivisual components. SOLUTION: The joint structure of a retractable roof mounted antenna comprises a joint part 33, a set of pivotal support parts 32a and 32b, a click cylinder 34, a coil spring 35, and a bolt and nut 38 and 42. In a first cylindrical member with a bottom of the joint part 33, an inner face of the bottom of the cylindrical member is provided with a projecting part 331, and the outer face of the bottom is provided with a first terminal part 33a to be electrically connected to an antenna rod. The pivotal support parts 32a and 32b are provided with a through hole 32 and a second terminal part 322 to be electrically connected to the first terminal part in a slidable way. A second cylindrical member with a bottom of the click cylinder 34 is inserted into the first cylindrical member with a bottom from the bottom side of the cylindrical member, and the outer face of the bottom is provided with a recessed part 341 to be engaged with the projecting part 331. The coil spring 35 is inserted into the second cylindrical member with a bottom and they are clamped and screwed. COPYRIGHT: (C)2008,JPO&INPIT
