<p>PROBLEM TO BE SOLVED: To improve usability by providing an extra width for core positioning between a primary side and a secondary side of a non-contact transmission coupler which carries out power transmission by magnetic coupling. SOLUTION: A pair of disc-like magnetic cores 1, 1 having an annular groove 12 for coil winding in one surface are opposed so that the surfaces at the annular groove 12 side face to each other. Thereby, power transmission by magnetic coupling is carried out from a coil L1 of one core 1 to a coil L2 of the other core 1, and a diameter (a) of a middle leg part 11 positioned inside the annular groove 12 and a width (b) of the annular groove 12 awe made almost the same size.</p> |
