PURPOSE: A wireless charging device for an electric vehicle using power frequencies is provided to maximize the efficiency of delivering electric power by minimizing magnetic resistance and a gap between a current core and a feeding core. CONSTITUTION: A feeding core support plate(640) is installed on the inner bottom of a feeding core chamber(62). A sliding roller part is installed between the inner bottom of the feeding core chamber and the feeding core support plate. The sliding roller part comprises a plurality of rollers(650) which move the feeding core support plate from side to side. A spring support unit is vertically installed to the feeding core support plate. A feeding core delivers the magnetic field to a current core. |
