<p>PROBLEM TO BE SOLVED: To provide a rotation sensor capable of measuring rotation angle and torque with a single sensor and reducing the weight. SOLUTION: In this rotation sensor, a case 4 cooperates with first and second rotors 2 and 3 to form an annular space S inside. In the annular space S, a base board 5 having first and second electric conductors 5a-5f formed on the surface and turning with the first rotor 2, a first holding member 1 holding first brushes 6a and 6b, which are brought into contact with the first electric conductors 5a and 5b for detecting information accompanying the rotation of the first and second rotors as a voltage change, and a second holding member 7 holding second brushes 7a-7d, which are brought into contact with the second electric conductors 5c-5f for detecting information accompanying the rotation of the first and second rotors 2 and 3 as a voltage change, are arranged respectively.</p> |
