Abstract: A peripheral equipment for telecommunication is foldable and attachable to a steering wheel of vehicles. More particularly, it is easily mounted onto a steering wheel and extendable for use and foldable for storage. Thus, it will not interfere with the normal operation of a steering wheel and block a driver's visual sight of the gauges on a dashboard of a vehicle. Besides, it permits a driver to extend and fold at random a peripheral equipment for telecommunication, such as automatic fee collecting systems at fee collecting stations, dialing operators of cellular phones, incoming phone indicators and etc. during driving without moving his or her hands off a steering wheel or shifting the driver's view from a moving course. Thereby, drivers can process telecommunication information and drive vehicles safely at the same time. Such a peripheral equipment is made up of an information box and a mount which permit a driver to extend and fold with readiness.
