In addition, the torque detector on the input side, the electric motor on the output side, the electromagnetic clutch and the control circuit section are housed in the same case, so the wiring between them can be shortened and the number of connecting members such as couplers can be shortened. Can be reduced, and thus operational reliability can be improved. Further, according to the above, the number of parts is reduced, and the cost can be reduced. In addition, the need for special electrical and magnetic shields is eliminated, and the functions of the entire device are integrated,
The mountability and compatibility can be improved.
