Abstract
A power-receiving coil device is installed inside an exposed part housing. The power-receiving coil device includes a power-receiving-side coil part that receives power from a power-transmitting-side coil part of a power-transmitting coil device, and a power-receiving-side core magnetic body. The power-receiving-side coil part has a first power-receiving coil and a second power-receiving coil which are arranged along a direction of a coil axis. An outer width of the first power-receiving coil is smaller than an outer width of the second power-receiving coil when viewed along a front-back direction perpendicular to the coil axis.
