<p>PROBLEM TO BE SOLVED: To realize reduction in size and thickness by forming, in almost V- shape, a secondary core provided in the vehicle side to which a primary side coupler in the charger body side is inserted. SOLUTION: A secondary core 1 of which external shape is set to almost V-shape is provided to a charge port of which inserting port is opened toward the external side of vehicle. Meanwhile, a thin-tongue type coupler 4 is provided to a primary side charger, the coupler 4 is provided with a primary side core 3, and a primary side coil 31 is provided at the internal side of the core 3. In addition, a coupling portion provided in the vertical direction connecting the upper and lower surfaces is formed to the secondary core 1. The secondary coil 11 partially winding several turns is provided and is then connected to the onboard battery side. At the internal surface of the upper and lower surfaces facing to the inserting portion of the core 1, a disk type core projection is respectively formed to the corner areas at the center. As a result, reduction in size and thickness can be realized by reduction of width of secondary core and moreover reduction in width and thickness size of charge port.</p> |
