Abstract: There is disclosed a structure of a rod antenna guide port in a cellular telephone comprising a rod antenna guide port for allowing a rod antenna in a cellular telephone to be pulled out therethrough with an inclination, the guide port including an upper and a lower sleeve hole for allowing the rod antenna to be inserted therein, the lower sleeve hole serving as means for pressing, when the rod antenna is pulled out, one side surface of a lower end portion of the rod antenna so that the rod antenna is offset to one side, thereby enabling to pulling out the rod antenna with an inclination through the upper sleeve hole, wherein the upper sleeve hole includes a slit sleeve composed of a plurality of slit elements annularly arranged, a split spring sleeve being externally fitted to the slit sleeve so that the slit sleeve can be expanded and contracted in a radial direction, the slit elements of the slit sleeve being pressed by the rod antenna pulled out with an inclination so that the slit elements are expanded (
