Abstract
A torque detector capable of detecting an amount of torque, rotation angle and rotational speed with high resolution. First rotor and second rotor are retained individually in bearings, and they each have a gear on periphery thereof. First magnet and second magnet have pairs of magnetic poles, and disposed to ends of the first rotor and the second rotor respectively. First and second magneto-sensitive elements for detecting magnetic fields produced by the first and the second magnets are placed along an axial direction of the first and the second rotors in a manner to face the first and the second magnets respectively with a predetermined space. An input shaft and an output shaft are in engagement to the first and the second rotors respectively with gears, and the output shaft is connected to the input shaft.
