According to an embodiment of the present invention, a yard tractor charging facility includes: a yard tractor which includes a pickup plate for current collection in a planar shape installed on a lateral side thereof; and a feeding unit which generates an induction current in the pickup plate for current collection by forming a magnetic field on the pickup plate for current collection while being adjacent to the pickup plate for current collection. The feeding unit includes: a housing which has an inner space; a feeding coil which is installed in the inner space; and a distance control unit which controls a distance between the feeding coil and the pickup plate for current collection by moving the feeding coil. Accordingly, the present invention can easily supply power to the yard tractor.
