1. An inspection device for a contactless power feeding facility comprising: a first feeder line and a second feeder line disposed parallel to each other along a moving route of a mobile object provided with a power receiver; and a power supply configured to supply an alternating current to the first feeder line and the second feeder line, and configured to cause a receiving coil of the power receiver to generate an induced electromotive force by magnetic fields generated by the first feeder line and the second feeder line,
the inspection device comprising:
an inspection coil disposed between the first feeder line and the second feeder line for inspection and configured to generate the induced electromotive force by the magnetic fields generated by the first feeder line and the second feeder line;
a core around which the inspection coil is wound;
a pair of output lines individually connected to each of both ends of the inspection coil; and
a cover formed to cover the inspection coil and the core with an insulating material having electrical insulation properties, wherein:
using a direction along an axial center of the inspection coil as an axial direction, a first side in the axial direction as an axial first side, a second side in the axial direction as an axial second side, directions orthogonal to the axial direction as radial directions, and a specific direction among directions along the radial directions as a specific radial direction,
the cover comprises:
a coil cover portion formed to cover the inspection coil; and
a projection portion disposed on the axial first side with respect to the coil cover portion and formed to project to both sides at least in the specific radial direction with respect to the coil cover portion, and
using an interval in design between the first feeder line and the second feeder line as a design interval:
a dimension in the specific radial direction of the coil cover portion is smaller than the design interval, and
a dimension in the specific radial direction of the projection portion is larger than the design interval.
