US 2007/0180905 A1 · Torque detecting apparatus and manufacturing method of same

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.
