摘要： A torsion bar has first and second end portions that are fixed to input and output shafts, respectively, to coaxially connect between the input and output shafts. A multipolar magnet is fixed to the input shaft. First and second magnetic yokes are fixed to the output shaft. Magnetic sensors are held between magnetic flux collecting portions of first and second magnetic flux collecting rings, which are magnetically coupled to the first and second magnetic yokes, respectively. In each of the magnetic flux collecting portion, a connecting section and a mounting section are configured such that a width of the connecting section is smaller than a width of the mounting section.

摘要： A magnetic sensor includes a magnetic sensing device, a sensor housing and a pair of magnetic flux guide members. The sensor housing includes a base body and a flange. The base body holds the magnetic sensing device at one end portion of the base body. The flange is fixed to the base body and is configured to be placed in contact with a receiving wall that receives a first magnetic circuit portion and a second magnetic circuit portion. The flange is made of a material having a higher rigidity than the base body.

摘要： A torque detecting device detects a torsional torque between a first shaft and a second shaft based on a torsional displacement of a resilient member linking the first shaft and the second shaft coaxially. The torque detecting device is provided with: a magnet fixed to the first shaft; a first yoke fixed to the second shaft and arranged to be rotatable with respect to the magnet; a second yoke fixed to the second shaft and arranged to be rotatable together with the first yoke with respect to the magnet; a magnetic flux collector which collects magnetic flux; and a magnetic sensor which detects magnetic flux density. The magnetic flux collector is located to face both the first yoke and the second yoke. The magnetic sensor is located between the first yoke, from among the first yoke and the second yoke, and the magnetic flux collector, and detects the magnetic flux density between the first yoke and the magnetic flux collector.

摘要： Claw portions opposing a magnet are disposed on inner edges of a first yoke and a second yoke. Wall portions are disposed on outer edges of the first yoke and the second yoke so as to extend in an axial direction. A distal end of the wall portion and another distal end of the other wall portion are spaced apart from each other in the axial direction and disposed to oppose each other. A magnetic sensor is disposed between the distal ends in the axial direction. End faces oblique to the axial direction are disposed on the distal ends and a distance between the distal ends on a radially inner side is made shorter than a distance between the distal ends on a radially outer side.

摘要： A hole is formed in a substrate of a magnetic detection device, the hole being spaced away from an outer edge of the substrate. Magnetic detection elements of a magnetic sensor detects magnetic field formed at first and second collector portions. A mold section encapsulates the magnetic detection elements. The magnetic sensor is surface mounted such that a portion of the mold section overlaps with the hole. The first collector portion faces a front surface of the magnetic sensor. A portion of the second collector portion is positioned in the hole to face a rear surface of the magnetic sensor. Accordingly, compared to a case where a hole is not provided, a magnetic circuit gap between the first and second collector portions is reduced.

摘要： A sensor housing has a receiving recess at one end portion of the sensor housing located at one end of the sensor housing. The one end portion of the sensor housing faces first and second magnetic circuit portions. A circuit board is received in the receiving recess and has an opening, a front-side region and a rear-side region. The front-side region is located on a side of the opening where the one end of the sensor housing is placed. The rear-side region is located on an opposite side of the opening. A main body of a magnetic sensing device overlaps the opening such that terminals projecting from one of a pair of side walls of the main body are located at the front-side region, and terminals projecting from another one of the pair of side walls is located at the rear-side region.

摘要： A torque sensor is provided with a torsion bar which converts torque applied between a first shaft and a second shaft into a torsional displacement. A multipole magnet is fixed to one end side of either the first shaft or the torsion bar and in which N poles and S poles are magnetized alternately in a circumferential direction. A plurality of first yokes is provided in the circumferential direction on a radially outer side of the multipole magnet. A plurality of second yokes is provided in the circumferential direction on the radially outer side of the multipole magnet in such a way that each second yoke is sandwiched between two first yokes. A set of magnetic flux collecting members includes a first main body portion and a second main body portion, and forms a magnetic circuit in conjunction with the plurality of first yokes and the plurality of second yokes in a magnetic field generated by the multipole magnet. A magnetic sensor is provided radially outside the first main body portion and the second main body portion to detect a magnetic flux density generated in the magnetic circuit.

Magnetic detection elements of a magnetic sensor detects magnetic field formed by first and second collector portions. A mold section encapsulates the magnetic detection elements. The magnetic sensor is surface mounted such that a portion of the mold section overlaps with the cutout portion. The first collector portion faces a front surface of the magnetic sensor. A portion of the second collector portion is positioned in the cutout portion to face a rear surface of the magnetic sensor. Accordingly, compared to a case where a cutout portion is not provided, a magnetic circuit gap between the first and second collector portions is reduced.
