摘要： 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.

摘要： In a torque sensor, a first detection tube (13) made from magnetic material covers a cylindrical magnetic leak prevention member (12) that is made from nonmagnetic material and covers a first shaft (3) made from magnetic material. Magnetic resistance to magnetic flux, which passes through one end of the first detection tube (13) and one end of a second detection tube (14) that is made from magnetic material and rotates together with a second shaft (4), changes according to elastic relative rotation of the two shafts (3, 4) corresponding to transmitted torque, by providing a plurality of teeth (13a, 14a) along the circumferential direction at the one end of each detection tube (13, 14). The first shaft (3) and the first detection tube (13) are integrated with the magnetic leak prevention member (12) so that they can rotate together, by being inserted in a mold for forming the magnetic leak prevention member (12) before the synthetic resin material is poured into the mold. The circumferential width of each resin holding space (13A) between the teeth (13a) arranged along the circumferential direction at one end of the first detection tube (13) decreases gradually toward the other end of the first detection tube (13). The synthetic resin material solidified in the resin holding spaces (13A) is pressed against the teeth (13a) due to shrinkage thereof.
