摘要： A yoke assembly (5) is constructed by retaining integrally a yoke ring (50) having positioning holes (54, 54) aligned with pole claws (51, 51 ...) arranged equally on the inner circumference and a yoke ring (50) having positioning holes (55, 55) aligned with the space between pole claws (51, 51...) arranged equally on the inner circumference by a retaining cylinder (52) made of a resin. The retaining cylinder (52) has a pin hole (56) remaining after pulling out a common positioning pin inserted into the positioning holes (54, 55) during molding.

摘要： A torque detecting apparatus detects torque applied upon a torsion bar of an electric power steering apparatus, as two sensors 1, 2, which have ratiometric characteristics and have the same characteristics, simultaneously detect the amount of torsion of the torsion bar. With a gain of one of the two sensors 1, 2 set to the positive polarity and a gain of the other sensor 1 or 2 set to the negative polarity, a control circuit calculates the torque applied upon the torsion bar by multiplying a difference between detection outputs from the two sensors 1, 2 by a predetermined coefficient. A torque detecting apparatus which is capable of detecting the torsional angle of a rotation shaft 5, namely, torque applied upon the rotation shaft 5 easily and accurately using two sensors 1, 2 is thus realized.
