Abstract:
A torque detector includes a torque cam, a pulse gear, a rotation pulse detection member, and a torque acquisition member. The torque cam is disposed on a rotating shaft and capable of moving in an axial direction of the rotating shaft according to torque input to the rotating shaft. The pulse gear includes a tooth formed on an outer circumferential surface of the torque cam. The rotation pulse detection member disposed so as to oppose the pulse gear is configured to detect the tooth of the pulse gear in rotation and to output a pulse train. The torque acquisition member is configured to acquire the torque from the pulse train. The tooth extends in the axial direction and a tooth thickness becomes continuously larger or smaller from a first side to a second side in the axial direction.
