PURPOSE:To attain a compact mechanism and stable and smooth telescopic operation by forming the cross section of a telescopic operation wire so as to have a flat face having 1.5-2.2 times of the width to the thickness and winding the wire on a winding turning body while the direction of the thickness of wire is taken radially. CONSTITUTION:The cross section of a telescopic operation wire 1 has the flat face 12 whose width (w) is 1.5-2.2 times to the thickness (t), the wire 1 is led to an antenna constituent 9 through an antenna base cylinder 7, a guide means receiving a broadwise end of the wire 1 is provided between the antenna base cylinder 7 and the winding turning body 2 so that the wire is wound on the winding turning body 2 while the broadwise direction of the wire 1 is taken radially. The telescopic operation wire 1 is made of a hard synthetic resin with a non-contracting property but having a tendency showing the thickness restoration such as the linearity in the releasing state such a material as polyacetar, the cross section has a rectangle or equivalent, the flat faces 12 are used in the direction of height, the symmetrical cross section at least in the right/left direction and the flat faces 12 are provided opposingly.
