PROBLEM TO BE SOLVED: To solve the problem of abnormal noise by preventing the vibration of a feeding terminal part at the lower end of an antenna caused by the vibration of a housing even at any position between a completely housed state of the antenna and its maximumly extracted state. SOLUTION: In a housing part structure of a retractable antenna, wherein an antenna guide tube is provided in the housing of portable communication equipment and the antenna is retractably housed in the antenna guide tube, the cross section shape of the antenna guide tube 6 is formed in a noncircular shape so that the lower end part (feeding terminal part 22) of the antenna is always brought into at least partial contact with the inner circumference of the antenna guide tube 6. Concretely, the guide tube 6 is crushed in a radial direction to form an elliptical part 61 in cross section. COPYRIGHT: (C)2006,JPO&NCIPI
