Torque detecting apparatus and manufacturing method of same

摘要

A torque detecting apparatus includes two magnetism collecting rings (5) cylindrical portions (51) enclosing a magnetic circuit forming member (4) provided on a rotating body (2, 3) and a magnetism sensitive device (6) disposed between the protruding pieces (52) protruding from parts of the cylindrical portions (51) in an radially outward direction of the cylindrical portions (51). It includes a regulating body (10) for regulating a relative position between the magnetism sensitive device (6) and the protruding pieces (52) respectively. This regulating body (10) includes two inserting recesses (10a) into which each of protruding pieces (52) is inserted respectively, each recess having a prismatic shape. It also has a connecting part (10b) connecting inner edges of apertures of the inserting recesses (10a) to each other. It also has a holding part (10c) holding the magnetism sensitive device (6) between the inserting recesses (10a).
