Abstract
A torque detection device includes: a torsion bar that couples a first shaft to a second shaft; a magnet that is fixed to the first shaft; and a pair of magnetic yokes that are fixed to the second shaft and that are arranged to face each other in an axial direction. Each of the magnetic yokes includes a yoke ring and a plurality of lugs that are arranged in a circumferential direction on the corresponding yoke ring. Each yoke ring includes an extending portion that extends radially outward from base portions of the lugs, and a bent portion that is bent in the axial direction from a radially outer end portion of the extending portion. The outer size of the pair of magnetic yokes in the axial direction is larger than or equal to the length of the magnet in the axial direction.
