Abstract

A torque sensor includes a first resolver (1) that outputs a signal corresponding to a rotation angle of a first rotor (10) fitted on an outer periphery of a first rotary shaft (S1), and a second resolver (2) that outputs a signal corresponding to a rotation angle of a second rotor (20) fitted on an outer periphery of a second rotary shaft (S2) coupled to the first rotary shaft (S1) via a torsion bar (3). The torque sensor detects a torque exerted on the first rotary shaft (S1) or the second rotary shaft (S2) based on the signals output from the first resolver (1) and the second resolver (2). A first junction between the first rotary shaft (S1) and the first rotor (10), and a second junction between the second rotary shaft (S2) and the second rotor (20) are formed so as to have different shapes or different sizes.
