摘要： PROBLEM TO BE SOLVED: To provide an assembly method capable of easily positioning a resolver rotor.
SOLUTION: In this assembly method, a cylindrical member 34 for accepting and fixing a torsion bar 24 inside and this resolver sub-assembly 33 comprising the resolver rotor 32 fixed on the outside of the cylindrical member 34 are assembled together. The resolver rotor 32 is fixed on the periphery of a sleeve 28 having a recessed part formed on a part in the circumferential direction on the end face by using the recessed part as a standard position in the rotation direction, and the sleeve 28 and the resolver rotor 32 are set on a jig to be engaged with the recessed part, having a projecting part not interfering with the resolver rotor 32 and a dummy part having the same shape as a fixing part of the torsion bar 24, and the cylindrical member 34 is pressed into the sleeve 28 in the state where the cylindrical member 34 is engaged with the dummy part.

摘要： PROBLEM TO BE SOLVED: To provide a torque sensor having stopper parts formable in a compact structure for preventing excessive torsional deformation of a torsion bar.
SOLUTION: In this torque sensor 10, the stopper parts 19 and 27 are provided on each other's loose-fit portions of first and second extension sleeves 15 and 16 fixed to one end and the other end of the torsion bar 14, and a rotary tube 69 provided on a second resolver 60 is fitted to the outside of the second stopper part 27 of the second extension sleeve 16 and also used for reinforcing the sleeve 16. Therefore, the sensor 10 can be formed in a compact structure as a whole as compared with a case where the rotary tube 69 is not used for reinforcement.
