The torque sensor has pins (211) erected on the axial direction of the torsion bar (10) arranged on an input side cylinder (21) fixed on the input end of the torsion bar (10). The torque sensor also has holes (221) having axial directions consistent with the shaft of the torsion bar (10) arranged on an output side cylinder (22) fixed on the output end of the torsion bar (10). The diameters of the pins (211) are smaller than those of the holes (221). When no torque is exerted on the torsion bar (10), the input side cylinder (21) and the output side cylinder (22) are connected with the torsion bar (10) in a way that the pins (211) of the input side cylinder (21) are respectively inserted into the centers of the holes (221) of the output side cylinder (22). When excessively large torque is exerted on the torsion bar (10), the pins (211) contact the edges of the holes (221). The excessively large torque is then prevented from being exerted between the input end and the output end of the torsion bar (10).
