<p>PROBLEM TO BE SOLVED: To provide a small and light magnetically coupling equipment for electric motorcar charging. SOLUTION: A secondary unit 20 is constituted by winding a secondary coil 22 around a secondary core 21 whose side surface is L-shaped. A first unit 10 consists of a primary core 11 and a primary coil 12, and has the same form as the secondary unit 20. The coil units 10 and 20 are made to face each other in such a manner that the coils 12 and 22 are laterally arranged, and bonded to each other. Thereby a closed loop magnetic circuit forming a square frame is constituted by the cores 11 and 21. In this state, the bonding surface of both the cores is in the counter relation intersecting the installation direction A, so that the installation space for the secondary unit can be prepared to be opened toward the outside of a vehicle, and the depth dimension can be remarkably reduced. The coils 12 and 22 are arranged laterally to the installation direction A, so that more compact configuration is realized.</p> |
