摘要： 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.

摘要： PROBLEM TO BE SOLVED: To provide iron-base sintered parts which have high density and totally enhanced strength, toughness and abrasion resistance; a method for manufacturing the iron-base sintered parts; and an actuator. SOLUTION: The iron-base sintered parts are formed from an iron-nickel-molybdenum-carbon-base sintered alloy, have a density of 7.25 g/cm 3 or higher, and have a carburization-quenched structure. The method for manufacturing the iron-base sintered parts comprises sequentially: a molding step of charging a raw mixture powder of an iron-nickel-molybdenum-based metal powder and a carbon-based powder into a cavity of a molding die, and compressing the raw powders in the cavity to form a compacted body; a sintering step of sintering the compacted body at a sintering temperature to form a sintered alloy; and a carburization quenching step of heating the sintered alloy in a carburization atmosphere and quenching the heated alloy.

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.
