Abstract
The present invention relates to a torque measuring device including a stator arranged at an inner surface of a case housing, a magnet distantly arranged with the stator at a predetermined gap, a sensing unit detecting a magnetic field generated between the stator and the magnet, and a non-magnetic stator holder integrally formed with a stator fixture fixed by the stator and a shaft fixture fixed by a shaft, whereby manufacturing cost of the torque measuring device can be minimized, and defects generated in the course of manufacturing process can be minimized.
