ALIGNMENT SYSTEM OF NONCONTACT POWER SUPPLY DEVICE

PROBLEM TO BE SOLVED: To present an alignment system of a noncontact power supply device being capable of providing positional-displacement information such as positional-displacement information in the horizontal direction first and being simply and easily actualized second.SOLUTION: In the alignment system, magnets 15 are arranged to one of a vehicle B or the like and the ground A side and a pair of reed switches 16 to the another. Both reed switches 16 are distributed and arranged on both sides of a center line D of both mutual reed switches 16, and can detect the magnetic fields of the magnets 15 while interposing an air gap when performing an alignment before power supply. The magnets 15 are set in a relationship where a secondary-side coil 5 is positioned corresponding to the primary-side coil 3 of the noncontact power supply device 1 when the magnets 15 are made positioned corresponding to the center line D. Consequently, the positional-displacement information on whether or not the secondary-side coil 5 is positioned corresponding to the primary-side coil 3 can be provided on the basis of the detecting signals of both reed switches 16.
