PROBLEM TO BE SOLVED: To improve assembling workability without causing irregularity of quality and deterioration of precision, and enable manufacturing at a low cost. SOLUTION: An annular motor stator 18 is arranged in a housing 14, and a motor rotor 19 is fixed to a power transmission shaft 12 so as to face the motor stator 18. A sensor rotor 23 is formed integrally with one end side inner periphery in the axial direction of the motor rotor 19, and a sensor stator 24 is arranged on the inner peripheral side of the sensor rotor 23. The motor stator 24 and the motor rotor 19 are positioned in the case of manufacturing, so that positioning of them is unnecessary in the case of assembling to the power transmission shaft 12. |
