Beschreibung
Zusammenfassung:	A torque detection device includes a yoke unit. The yoke unit includes a first magnetic yoke and a second magnetic yoke. The first magnetic yoke and the second magnetic yoke each are formed of a strip-shaped soft magnetic plate. The first magnetic yoke has yoke proximity portions and yoke distant portions that are formed by bending the soft magnetic plate. The second magnetic yoke has yoke proximity portions and yoke distant portion that are formed by bending the soft magnetic plate. The distance between each of the yoke proximity portions and a permanent magnet is shorter than the distance between each of the yoke distant portions and the permanent magnet.
