Abstract
A torque detecting apparatus according to the present invention includes a first shaft and a second shaft connected coaxially to each other through a connecting shaft, a permanent magnet fixed to the first shaft, a plurality of soft magnetic members having a collar provided therein, fitted by pressing with the second shaft and disposed in a magnetic field of the permanent magnet to form a magnetic circuit, and a detector for detecting magnetic flux generated from the soft magnetic members, wherein the soft magnetic members are integrally molded with a mold body made of synthetic resin, and when a torque is applied to the first shaft or the second shaft, the torque is detected based on an output of the detector. The collar is made of a non-magnetic material.
