摘要： A pair of cylindrical magnets with cut away portions has been arranged on both sides of a magnetic sensing element in symmetry of rotation, and a yoke surrounds the magnetic sensing element in contact with outer peripheral surfaces of the pair of the cylindrical magnets with cut away portions. The pair of the cylindrical magnets with cut away portions rotates around an axial center with a concurrent axial displacement along with a rotation of a rotating body. The pair of the cylindrical magnets with cut away portions is arranged in inclined manner against an axis-of-rotation of the magnet. Thereby, the rotation and the displacement in the direction of the axis against the magnetic sensing element of the pair of the cylindrical magnets with cut away portions, and the number of times of rotation can be detected by detecting the size of the magnetic flux density by the magnetic sensing element. The pair of the cylindrical magnets with cut away portions improves the size and linearity of the magnetic field on the axial center.

摘要： A driving gear, which is a scissors gear, fixed to a rotating body, engages with a driven gear, and the driven gear engages with a fixed screw receiver. A first gear and a second gear of the driving gear elastically bias the tooth of the driven gear by a coil spring in the direction of an inner side of a diameter; consequently the driven gear 5 is forced on the screw receiver. Gears formed in the tooth tips of the driven gear engage with a partial spiral screw of the screw receiver.

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.
