Abstract: In an insulator inserted in an insulator accommodation hole of a bracket body portion, an inclined portion is formed in an inner periphery of a first cylindrical body portion of a first core metal, the inclined portion being provided anterior to an internal thread portion in an inserting direction of a bolt and reduced in diameter toward the rear side in the inserting direction.

Abstract: The alignment of a nut and a nut-side pulley is performed by: a nut insertion step of inserting the nut into the nut-side pulley; a temporary tightening step of, after the nut insertion step, inserting a shaft portion of a fastening bolt in a fastening bolt insertion hole of the nut-side pulley, with the shaft portion being inserted through a spring washer, and then, tightening the shaft portion into an internal thread of the nut until a dimension of the spring washer becomes shorter than a free length and longer than a fully compressed length; an axis deviation adjusting step of adjusting a position of the nut-side pulley relative to the nut to decrease a deviation of the nut-side pulley relative to a rotation axis of the nut after the temporary tightening step; and a final tightening step of further tightening the fastening bolt after the axis deviation adjusting step.

Abstract: A power steering apparatus includes: a first detection element arranged to sense a rotation angle of the first gear based on a variation of a magnetic field generated by the first magnetic member; a second detection element arranged to sense a rotation angle of the second gear based on a variation of a magnetic field generated by the second magnetic member; an absolute steering angle calculating circuit configured to calculate an absolute steering angle of the steering wheel from an neutral position of the steering wheel at which the steered wheel directs in a straight direction, by a combination between the rotation angle of the first gear and the rotation angle of the second gear; and a control section configured to drive and control the electric motor based on the absolute steering angle.

Abstract: A steering angle sensor for a vehicle including a steering angle sensor housing, a first gear, a rotation transmitting portion, a second gear meshing with the first gear, a third gear meshing with the first gear or the second gear, first and second magnetoresistance effect elements to detect first and second rotation angles as rotation angles of the second and third gears, respectively, and a biasing member disposed in the steering angle sensor housing to bias the first gear toward the second gear, wherein the first and rotation angles are combined to determine an absolute steering angle indicative of an amount of rotation of a steering wheel when the steering wheel is rotated from a neutral position in which a steerable road wheel is oriented to a straight ahead direction of the vehicle.

Abstract: A steering angle sensor 17 is provided which can minimize a detection error even when a steering shaft 6 is inclined. In an annular clearance t1 defined between the steering shaft 6 and an inner cylindrical wall of a first gear 24, there is compressed an elastic O-ring 23. Due to provision of the elastic O-ring 23, inclination of the steering shaft 6, which tends to occur during handling of a steering wheel 1, is suitably absorbed by the elastic O-ring 23, and thus, generation of detection error caused by inclination of the first gear 24, which would follow the inclination of the steering shaft 6, is suppressed or at least minimized.
