TORQUE DETECTING DEVICE

PROBLEM TO BE SOLVED: To provide a torque detecting device which reduces a possibility that a first and a second rotation members are damaged, in assembling the torque detecting device. SOLUTION: The torque detecting device for detecting the rotation torque imparted on the coaxially connected first and the second shafts 1 and 2 by the relative angle displacement generating between the first rotation member integrally rotating with the first shaft 1 and the second rotation member rotating with the second shaft 2 surrounding the first rotation member, where the resin mold 42 for fixing the rotary magnet 4 on the first shaft 1 is provided with the protruding parts 42a and 42b facing the resin mold 52 across the narrow gap narrower than the gap between the cylindrical magnet 4 and the yoke rings 5, 5. Hence, in assembling the torque detection device, the probability of the damage to be caused by the contact of the cylindrical magnet 4 and the yoke rings 5, 5 is reduced. COPYRIGHT: (C)2008,JPO&INPIT
