In this condition, as the tip of the antenna is pressed, the latch mechanism unlocks the lower end of the antenna and, at the same time, pushes the antenna out of the top of the casing 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.
