摘要： PROBLEM TO BE SOLVED: To reduce a working cost and an assembling cost.
SOLUTION: An outer circumference of a cylindrical magnetism leakage preventing member 12 made of a nonmagnetic material covering an outer circumference of the first shaft 3 made of a magnetic material is covered with the first detection cylinder 13 made of a magnetic material. The second detection cylinder 14 made of a magnetic material is rotated along with the second shaft connected elastically and relatively rotatably to the first shaft 3, and one end thereof is opposed to one end of the first detection cylinder 13 with a clearance therebetween. Magnetic resistance against a passing magnetic flux in the first magnetic circuit constituted by generating a magnetic flux passing through the one end of the first detection cylinder 13 and the one end of the second detection cylinder 14 by the first coil 16 is changed in accordance with an elastic relative rotational amount by transmission torque changes of the both shafts 3, 4. The magnetism leakage preventing member 12 is molded of a synthetic resin injected in a molding die. The first and second shafts 3, 4 are integrated to be rotated along with the magnetism leakage preventing member 12 die-molded by inserting the shafts 3, 4 into the molding die before the injection of the synthetic resin.
