<p>PROBLEM TO BE SOLVED: To obtain a noncontact-type transformer, in which delivery of a signal is surely enabled, when a gap exists in the steering axis direction between a primary side magnetic material core and a secondary side magnetic material core. SOLUTION: This noncontact-type transformer 10 is constituted by making an outside cylindrical magnetic material core 1 and an inside cylindrical magnetic material core 2 face each other. Each of the outside core 1 and the inside core 2 is of a low closed-end cylinder type, and one bottom surface of the cylinder is opened. The aperture surfaces are made to face each other, and the inside core 2 is arranged to creep along into the inside of the outside core 1. Circumferential trenches are formed on the side surface inner wall of the outside core 1 and on the side wall of the inside core 2. Windings 3a, 4a are arranged in the trenches, and each of the windings is positioned on the same surface.</p> |
