<p>PROBLEM TO BE SOLVED: To regulate sensor rings that they are rotated around axial lines of pins, by arranging the pins in such a position that respective axial lines of at least two pins by which the first and second sensor rings for torque sensors are attached on an input shaft and an output shaft, may not be matched to each other. SOLUTION: In a power steering gear by which the rotation of an assistant motor is decelerated so as to be transmitted as assist of steering force to an output shaft 2, a first sensor ring 81 of a torque sensor is fitted and inserted in an input shaft 1, and a tooth part 83 is formed at the end part of this first sensor ring 81. Then, a second sensor ring 82 in which a tooth part 84 overlapped on this tooth part 83 is formed, is fitted and inserted in the output shaft 2. At this time, both sensor rings 81, 82 are respectively fixed to the input shaft 1 or the output shaft 2 through a spacer 86 by two pins P1, P2, however, both pins P1, P2 are arranged in such a position that respective axial lines P1', P2' may not be matched to each other, thereby the second sensor ring 82 is regulated to be rotated around a pin shaft by both pins P1, P2.</p> |
