  • Patent number: 7886619
    Abstract: 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.

  • Patent number: 7509883
    Abstract: 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.
