摘要： A vehicle steering apparatus. The durability of a sensor rotor to heat and abrasion is improved. The flatness of the sensor rotor is prevented from being lowered during calking for coupling of the sensor rotor to a steering shaft so that steering torque of a driver can be more accurately detected. A fabrication process is simplified, and fabrication costs are reduced.

摘要： A sensor device that can suppress deformation of a holder due to a molding pressure applied during injection molding of a housing is provided. A second magnetism collection portion holder has a suppression portion that projects from a second holder body portion toward a first holder and that suppresses deformation of the holder due to the molding pressure applied during the injection molding. The distal end surface of the suppression portion abuts against the inner surface of a first holder body portion with the first holder and a second holder assembled to each other with a sensor unit interposed therebetween.

摘要： A torque sensor includes: an annular deformation body; first and second displacement electrodes which cause displacement by elastic deformation of the annular deformation body; first and second fixed electrodes arranged at positions opposite the first and second displacement electrodes; and a detection circuit that outputs an electric signal indicating a torque based on a variation amount of capacitance values of first and second capacitive elements each of which is configured of the displacement electrode and the fixed electrode. The annular deformation body includes a high elastic portion and a low elastic portion having a spring constant smaller than a spring constant of the high elastic portion. The detection circuit determines whether the torque sensor functions normally based on a ratio between first and second electric signals.

摘要： A magnetostrictive torque sensor is provided that is capable of maintaining high detection accuracy, even when an excessive torque acts on a rotary shaft. The magnetostrictive torque sensor includes a magnetostrictive film 71 that is arranged on a second steering shaft 23, or a rotary shaft, having a substantially columnar shape so as to surround the second steering shaft 23 around its axis, and detects a rotational torque about the axis acting on the second steering shaft 23 based on a change in a magnetic property of the magnetostrictive film 71. Compressive stress remains on an outer circumferential surface of a sensor region 77 of the second steering shaft 23 around which the magnetostrictive film 71 is arranged. A plated layer of the magnetostrictive film 71 is arranged on the outer circumferential surface of the sensor region 77 in which compressive stress remains.

摘要： The present invention provides a torque sensor that is small and highly rigid and for which high production efficiency is possible. An annular deformation body (50) is disposed between a left side support body (10) and a right side support body (20). Protruding parts (11, 12) of the left side support body (10) are joined to two upper and lower sites on the left side surface of the annular deformation body (50), and protruding parts (21, 22) of the right side support body (20) are joined to two left and right sites on the right side surface of the annular deformation body (50). The annular deformation body (50) has, at four sites, detection parts (D1 to D4) that cause elastic deformation, the right side surface of each of the detection parts (D1 to D4) moves close to or moves away from the opposing surface of the right side support body (20) when torque around the Z axis is exerted on the left side support body (10) in a state that a load is applied to the right side support body (20). A displacement electrode is formed on a right side surface of each of the detection parts (D1 to D4) and a fixed electrode is formed on an opposing surface of the right side support body (20) to constitute four sets of capacitive elements, thereby detecting torque exerted as fluctuation in capacitance value thereof.
