ROTATION RESTRICTION STRUCTURE OF GPS UNIT FOR CAR NAVIGATION APPARATUS

摘要

A rotation restriction structure of a GPS(Global Positioning System) unit for a car navigation apparatus is provided to improve external beauty by being located inside a main body not to be exposed. A rotation restriction structure of a GPS unit for a car navigation apparatus includes a pair of shaft holes(110), protrusions(120), hinge shafts(210), and curved protrusions(220). The pair of shaft holes is formed inside a main body. The protrusions are formed on inner circumferential surfaces of the shaft holes. The hinge shafts are formed on both sides of a rear part of the GPS unit and are inserted in the shaft holes, respectively. The curved protrusions are formed on ends of the hinge shafts and are locked by the protrusions of the shaft holes when the curved protrusions are rotated by a predetermined angle.
