摘要： A torque sensor includes first and second shafts, an elastic shaft, a magnet, a pair of ring plates, and a magnetic sensor. The elastic shaft connects the first and second shafts coaxially. The magnet is fixed to the first shaft. The pair of ring plates is fixed to the second shaft, and faces each other in an axial direction of the elastic shaft so that the pair of ring plates sandwiches the magnet. The magnetic sensor is disposed in a gap between the pair of ring plates so that the magnetic sensor detects a magnetic flux density in the gap. Each ring plate includes a convexity and a concavity in an inner circumference of each ring plate, respectively. The pair of ring plates is rotatable against the magnet in accordance with a twist of the elastic shaft so that the rotation of the ring plates causes the magnetic flux density in the gap.

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.

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.
