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： An angular position sensor is provided which is designed to an angular position of a rotary shaft. The angular position sensor has a magnet affixed to the rotary shaft. The magnet has an N-pole and an S-pole and is so geometrically shaped as to produce magnetic flux which is substantially uniform in amount within a range extending around each of centers of the N-pole and the S-pole. This improves the linearity of a change in sensor output upon rotation of the rotary shaft.

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 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.
