摘要： A torque detecting apparatus includes two magnetism collecting rings cylindrical portions enclosing a magnetic circuit forming member provided on a rotating body and a magnetism sensitive device disposed between the protruding pieces protruding from parts of the cylindrical portions in an radially outward direction of the cylindrical portions. It includes a regulating body for regulating a relative position between the magnetism sensitive device and the protruding pieces respectively. This regulating body includes two inserting recesses into which each of protruding pieces is inserted respectively, each recess having a prismatic shape. It also has a connecting part connecting inner edges of apertures of the inserting recesses to each other. It also has a holding part holding the magnetism sensitive device between the inserting recesses.

摘要： A detecting unit for detecting a torque applied to a rotor according to rotation of the rotor having an input shaft and an output shaft connected with each other by a torsion bar and a detection circuit board connected with the detecting unit are molded with synthetic resin material to form a mold member. The installation of the mold member into a housing, which has a cylinder portion to surround the rotor and a retainer having an opening formed at the peripheral wall of the cylinder portion, is achieved by inserting the mold member into the retainer from the radial direction through the opening of the retainer.

摘要： A torque detecting apparatus for detecting rotational torque applied to a first and a second shafts which are coaxially connected to each other by a torsion bar by using a relative angular displacement between a cylindrical magnet fixedly fitted onto the first shaft and integrally rotating with the first shaft and yoke rings surrounding an outer circumference of the first rotating member and integrally rotating with the second shaft. A facing portion is provided between the first and second shafts, and faces each other in the axial direction by a space smaller than a space between a lower end face of the first rotating member and the upper end face of the second shaft. Positioning in the axial direction of the cylindrical magnet and the yoke rings is carried out referring position where the space of the facing surface becomes zero.
