PROBLEM TO BE SOLVED: To solve a problem of a conventional telescopic mechanism of an antenna that the structure of the mechanism has been complicated because the mechanism requires a plurality of gears, a timing belt, an opening/closing spring or the like. SOLUTION: The antenna telescopic mechanism comprises: a first gear 8 fixed to a rotating shaft 2 of a hinge 6; a second gear 12 meshing with linear gears formed to an antenna 3; a third gear 11 fixed to a rotating shaft of the second gear 12; and a belt 14 stretched over the first gear 8 and the third gear 11. Then the antenna telescopic mechanism automatically extends/contracts the antenna 3 interlocking with opening/closing between a base 4 and a top 5 of a mobile phone terminal.
