An antenna handling mechanism incorporated in a portable radio communication apparatus (1) and including an antenna (2) which can be pulled out of the casing (7) of the apparatus, as desired. When the antenna (2) is received in the casing (7), the lower end (3) of thereof is locked by a latch mechanism (4) disposed in the casing (7). In this condition, as the tip (5) of the antenna (2) is pressed, the latch mechanism (4) unlocks the lower end (3) of the antenna and, at the same time, pushes the antenna out of the top of the casing (7) by a pushing stroke. When the antenna being inserted into the casing reaches a predetermined position, the latch mechanism locks the lower end of the antenna.
