PURPOSE: To provide a device suited to three-dimensional run of a movable body and capable of attaining size reduction, and large power receiving capacity by having a coil wound around a pickup core and forming a pair of plate parts made of a magnetic material, each of which is fixed to both open ends of a pickup core, respectively, and whose area is larger than the contact area of the fixed part with the respective open ends. CONSTITUTION: A pair of plate parts 25, 26, constituted of a magnetic material, such as ferrite respectively and formed into rectangular plate shapes to be identical in shape and size, are fixed to the opposing surface of the front ends of the upper and lower plate parts 24b, 24c of a pickup core formed into a C-shape. The area of each of the plate parts 25, 26 is made larger than the contact area of the plate parts 25, 26 with the upper and lower plate parts 24b, 24c of the pickup core. As a result, an air gap between the open ends is reduced and a magnetic path area is increased, thereby increasing the power receiving capacity. It is thus possible to attain a device suitable for three- dimensional run of a movable body and capable of attaining size and weight reduction in a pickup core. |
