Abstract
A torque detector detects a torsional torque between a first shaft and a second shaft based on a torsional displacement of an elastic member coaxially connecting the first shaft and the second shaft. The torque detector includes a magnetic flux generation unit and a magnetic sensor. The magnetic flux generation unit rotates with rotation of the first shaft and includes a first pole and a second pole into and out of which lines of magnetic force enter and exit. The magnetic sensor rotates with rotation of the second shaft and includes a detection surface for detecting a magnetic flux or a magnetic flux density. The first pole and the second pole are arranged to face each other across the magnetic sensor.
