Abstract
In order to implement a structure capable of improving the resolution of torque measurement while preventing the plastic deformation of a torsion bar (), an input-side stopper () having an uneven shape (gear shape) in the circumferential direction is provided in a portion of an input-side rotating body () that includes an input shaft () and an input gear (), and an output-side stopper () having an uneven shape (gear shape) in the circumferential direction is provided in a portion of an output-side rotating body () that includes an output shaft () and an output gear (). The input-side stopper () and the output-side stopper () are combined so as to be engaged to be able to transmit torque only when the torsional angle within the elastic range of the torsion bar () reaches a predetermined amount.
