Abstract
A torque detecting apparatus includes a first shaft; a second shaft; an elastic member coaxially linking the first and second shafts; and a magnet attached to the first shaft; a pair of magnetic yokes composed of a first magnetic yoke and a second magnetic yoke, the first and second magnetic yokes being fixedly installed on the second shaft; and a magnetic sensor. Each magnetic yoke includes an opposing portion and a wall portion. The opposing portion is opposed to the magnet and displaced circumferentially relatively to the magnet when the elastic member is subjected to a torsional displacement. The wall portions of the first and second magnetic yokes are separated and positioned outside the opposing portions in the radial direction. The wall portions of the first and second magnetic yokes extend to be mutually opposed. The magnetic sensor is positioned between the wall portions.
