Abstract

PURPOSE:To prevent unnatural buckling action force from being given to a wire, by expanding and contracting an antenna by winding or rewinding the wire by a pulley with a gear. CONSTITUTION:A rack 10a is formed on a wire 10 which operating expansion and contraction of an antenna element 51, and a pulley 7 with a gear which is driven by a motor 6 fitted to a base part body 1 is engaged with the rack 10a, and the wire 10 is wound into a drum 4 or rewound. In this case, the pulley 7 provided with the gear is fitted in one body together with the drum 4 which stores the wire 10, and the pulley 7 is provided rotatably for the motor 6 and the base part body 1 equipped with the element 51. A guide part body 3 which guides the wire 10 into the drum 4 is placed between the pulley 7 and the drum 4, and the part body 3 is held by the part body 1.
