摘要： A torque detecting apparatus according to the present invention comprises a first shaft (1) and a second shaft (2) connected coaxially to each other through a connecting shaft (3), a permanent magnet (5) fixed to the first shaft, a plurality of soft magnetic members (4a, 4b) having a collar (25) provided therein, fitted by pressing with the second shaft (2) and disposed in a magnetic field of the permanent magnet (5) to form a magnetic circuit, and a detector (6) for detecting magnetic flux generated from the soft magnetic members (4a, 4b), 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 (6). The collar is made of a non-magnetic material.
