Patent ID: 7886619

Claim:
A torque detecting apparatus comprising: two magnetism collecting rings, for concentrating a magnetic flux passing through a magnetic circuit forming member, including: cylindrical portions enclosing the magnetic circuit forming member provided on a rotating body to which torque is exerted; protruding pieces protruding from parts of the cylindrical portions in an radially outward direction of the cylindrical portions; a magnetism sensitive device, disposed between the protruding pieces; and a casing accommodating the magnetism collecting rings and the magnetism sensitive device, with the magnetism collecting rings being fixed with the casing, wherein the torque exerted on the rotating body is detected based on magnetism sensed by the magnetism sensitive device, wherein the torque detecting apparatus further comprises a regulating body for regulating relative locations between the magnetism sensitive device and the respective protruding pieces, wherein said casing includes a molded body molded with said regulating body using molten synthetic resin, wherein the regulating body has two inserting recesses into which the protruding pieces insert respectively, wherein the magnetism sensitive device is connected to a circuit board via leads and is molded with the circuit board and the leads by synthetic resin to provide a formed body, and wherein the formed body fits between the inserting recesses.
