Abstract
The present invention provides a non-contact power supply apparatus which is suitable for three-dimensional running by improving an allowable degree in a relative displacement of a carrier vehicle and a guide rail in the case where the carrier vehicle is running along the guide rail while receiving a drive power. The non-contact power supply apparatus has a pickup portion which is constructed in a manner that a pair of plate portions made of a magnetic material and having an area wider than a bonding area to an opening end are arranged in parallel, and are bonded or formed integrally with opposite surfaces of both opening ends of a pickup core having a C-letter or U-letter shape.
