PROBLEM TO BE SOLVED: To realize high precision in an induction-type displacement detection device by making it hardly affected by the misalignment, while increasing the intensity the transmission signal flowing in the transmission coil. SOLUTION: The induction type displacement detection device is a rotary type, and its transmission coil 105 is arranged in the stator. The transmission coil 105 extends from the terminal T1 in a ring shape, including the ring part 27 reaching the folding back part 25 and the ring part 29, with a radius different from that of the ring part 27 reaching the terminal T2 from the folding back part 25. The transmission coil 105 is composed of the upper conductor layer 15 and the lower conductor layer 17. COPYRIGHT: (C)2005,JPO&NCIPI |
