Abstract
In a rotatable antenna unit capable of being externally rotated away from and folded in a portable wireless device, an antenna detachment mechanism is provided, the antenna detachment mechanism composed of a bearing for rotatably supporting the antenna unit on the device by inserting therein and holding a pivot axis mounted on the device and an opening formed by cutting a part of the bearing. As a result, when an excessive external force is applied to the antenna unit being in an upright position, the opening is widened and the antenna unit comes off the portable wireless device. This prevents the antenna unit from being broken.
