摘要： A first shaft and a second shaft are connected coaxially. A torsion bar converts a torque applied between two shafts into a torsion displacement. A multipolar magnet is fixed to the first shaft. One set of magnetic yokes is fixed to the second shaft and disposed in a magnetic field generated by the multipolar magnet. The magnetic yokes are opposed to each other via an air gap in an axial direction. A magnetic sensor is provided for detecting the density of magnetic flux generated in the air gap. A non-magnetic spacer is disposed between the magnetic yokes as a means for positioning the magnetic yokes. The spacer and the magnetic yokes are integrated by resin molding.

摘要： A pair of magnetic flux collecting rings and a magnetic sensor are integrally covered by a molded resin to form a sub unit of a torque sensor. The pair of rings and sensors are integrated and are in contact with each other, i.e., the magnetic sensor is held in between respective magnetic flux collecting portions of the rings without any air gap formed therebetween. Magnetic flux collected by the rings can be detected by the magnetic sensor to a maximum degree, whereby the signal output of the magnetic sensor is enhanced and made stable.

摘要： A torque sensor is provided which consists of a magnet, an assembly of magnetic rings, and a magnetic sensor. The magnetic rings have claws arrayed thereround at regular intervals. Each of the claws of one of the rings is interposed between adjacent two of the claws of the other ring. Upon input of torque, the magnet is rotated relative to the ring assembly, thereby causing the density of magnetic flux to change as a function of the torque which is sensed by the magnetic sensor. Each of the claws is geometrically shaped so as to increase the density of magnetic flux flowing through the ring assembly, thereby improving the sensitivity of the sensor.

摘要： A torque sensor has a torsion bar coaxially in alignment with input and output shafts, a ring shaped magnet fixed to an axial end of the input shaft, a pair of magnetic yokes fixed to an axial end of the output shaft, and a magnetic sensor for detecting magnetic flux density generated between the pair of magnetic yokes. Each of the magnetic yokes is provided with claws, which are circumferentially spaced at constant intervals, and whose number is equal to that of each of N and S poles alternately arranged circumferentially in the magnet. Each, center of the claws coincides with a boundary between immediately adjacent N and S poles of the magnet, when the torsion bar is not twisted. The magnetic sensor is inserted into an axial gap between the pair of magnetic yokes without contacting the magnetic yokes.
