<p>PROBLEM TO BE SOLVED: To provide a non-contact power supply device which can quickly reduce air gaps and improve the efficiency of power supply, while suppressing changes in supplied power and increase in cost. SOLUTION: A pick-up 1 is comprised of a core 11, made of a magnetic material that is almost of E-shape, when viewed from the front, a coil 12 wound serially around the core 11, and a magnetic member 13 which is formed like a plate and is fitted detachably to an open part of the E-shaped core 11. Power supply wires 3 and 3 are surrounded by the core 11 and magnetic member 13, so that an air gap in a magnetic flux path due to a.c. current, running in the wires 3 and 3, is made as small as possible.</p> |
