    Abstract: A magnetic first detecting cylinder covers a magnetism leakage preventing member covering a first shaft. A second detecting cylinder is rotated along with a second shaft connected to the first shaft and one end thereof is opposed to one end of the first detecting cylinder with a clearance. A reluctance with respect to a passing magnetic flux in a first magnetic circuit constituted by generating the magnetic flux passing the first detecting cylinder and the second detecting cylinder by a first coil, is changed in accordance with an elastic relative rotational amount by a change in a transmitting torque of the two shafts. The magnetism leakage preventing member is molded from a synthetic resin material injected into a molding die. The first shaft and the first detecting cylinder are integrated to the magnetism leakage preventing member molded by being inserted into the molding die before injecting the synthetic resin material.

    Abstract: PROBLEM TO BE SOLVED: To provide a torque sensor preventing the lowering of torque detection accuracy owing to the contraction of a magnetic leakage preventive member made of synthetic resin material.
    SOLUTION: A tubular magnetic leakage preventive member 12 made of nonmagnetic material for covering a first shaft made of magnetic material is covered with a first detection tube 13 made of magnetic material. Magnetic flux passes through one end of the detection tube 13 and through one end of a second detection tube made of magnetic material, the second detection tube rotating together with a second shaft. Magnetoresistance to the magnetic flux changes according to elastic relative rotation corresponding to torque transmitted by the two shafts due to a plurality of teeth provided on one end of each of the two detection tubes along the circumferential direction thereof. The first shaft and the detection tube 13 are inserted into a forming die for the preventive member 12 prior to the injection of the synthetic resin material, and unified with the preventive member 12 so as to rotate together therewith. The circumferential interval W of a resin holding space in a circumferential interval between teeth 13a in one end of the detection tube 13 is gradually made smaller toward the other end of the detection tube 13. The resin material solidified in the holding space is pressed against the teeth 13a through its contraction.
