Abstract
In a magnetic coupling device for charging an electric vehicle which is used for charging a power storage device of the electric vehicle by means of a charging power source, a primary coil unit is inserted into a receiving unit which is on an electric vehicle and in which a secondary coil unit is disposed. In the device, junction faces of primary and secondary cores are formed in the insertion direction of the primary coil unit, and primary and secondary coils are disposed at positions where, when the primary coil unit 30 is inserted, the primary and secondary coils do not interfere with each other. Wiping members which wipe the junction faces are disposed. The insertion direction of the primary coil unit is in parallel with the longitudinal direction of the unit.
