<p>PROBLEM TO BE SOLVED: To provide a torque sensor capable of shortening axial size in a simple constitution and preventing reduction in detection accuracy. SOLUTION: An output shaft 4 is coupled to an input shaft 2 according to transferred torque elastically and concentrically so that they can be relatively rotated. The input and output shafts 2 and 4 are coupled to a ring-shaped member 71, which is arranged at a location surrounding at least one of either the input shaft 2 or the output shaft 4 and is deformable in the radial direction of the input and output shafts 2 and 4, by a coupling mechanism 73 so that the ring-shaped member 71 may be deformed in the radial direction of the input and output shafts 2 and 4 according to the amount of relative rotation of the input and output shafts 2 and 4. On the basis of the amount of deformation of the ring-shaped member 71 in the radial direction of the input and output shafts 2 and 4, a signal corresponding to torque transferred by the input and output shafts 2 and 4 is outputted.</p> |
