PROBLEM TO BE SOLVED: To easily and quickly assemble a rotation displacement detector without an offset adjustment. SOLUTION: A power steering device 11 has a motor housing 14 in which a brushless DC motor 14a is provided. The motor 14a has a drive stator 18 and a motor shaft 19, and a reslover 24 which detects the rotation displacement of the motor 14a is provided on the right side of the drive stator 18. The resolver 24 comprises a detection stator 25 and a detection rotor 27, and a spring member 26 is coupled and fixed to the detection stator 25. The spring member 26 has a flat spring 35 bendable radially. The flat spring 35 is placed between the motor housing 14 and the detection stator 25 and brought into contact with them. With such a constitution, a radial elastic force is generated between the detection stator 25 and the motor housing 14, and the detection stator 25 is rotatably fitted and fixed to the motor housing 14. |
