Abstract
To facilitate the charging of an electric automotive vehicle, a primary coil 31 connected with a charging power source is so provided as to project from a wall surface W of a parking space. An electric automotive vehicle E is advanced toward the wall surface W and parked in a position where the primary coil 31 is accommodated in a receptacle 11 provided below a front bumper B of the vehicle E. Then, a pressure switch 40 provided in a shock absorbing material 39 operates to detect the presence of the vehicle E, and the primary coil 31 is excited. A secondary coil 14 is provided above the receptacle 11. A voltage is generated in the secondary coil 14 by action of electromagnetic induction, thereby charging a battery 19.
