Abstract:
1. A torque sensor comprising: a torsion bar having a first end connected to a first shaft and a second end connected to a second shaft for converting a torque applied between the first shaft and second shafts into a torsional displacement; a multi-pole magnet fixed to one of the first and second shafts and the first end of the torsion bar; a multi-pole yoke fixed to one of the first and second shafts and the second end of the torsion bar for forming a magnetic circuit within a magnetic field generated by the multi-pole magnet; a pair of magnetic flux collecting members for collecting a magnetic flux from the multi-pole yoke; a magnetic sensor in magnetic communication with said pair of magnetic flux collecting members for detecting an intensity of the magnetic field generated by the multi-pole magnet; a first molded part formed to integrally include at least a portion of the magnetic sensor; and a second molded part formed to integrally include at least a portion of the pair of magnetic flux collecting members and including a holder portion holding the first molded part.
