PROBLEM TO BE SOLVED: To provide a sensor device capable of detecting rotational angle at a plurality of times.SOLUTION: Rotational members 3, 5 rotate a plurality of times and are coupled with a measurement value transmitter 7, and the measurement value transmitter 7 is coupled with the measurement value detector, for generating a signal representing the rotational angle of the rotational members 3, 5. The measurement value transmitter 7 is configured as a motion converter along with the rotational members 3, 5, and converts the rotation of the rotational members 3, 5 to a translation motion of the measurement value transmitter 7 related to the rotational member 3, 5. A first induction element arranged at the rotational members 3, 5 and second induction elements 12, 14 fixed in terms of position cause the translation motion of the measurement value transmitter 7, and the measurement value detector detects a corresponding position change of the measurement value transmitter 7.SELECTED DRAWING: Figure 1 |
