Claims

[Scope of utility model registration request]

An electric power steering device that detects torque on a steering shaft due to operation of a steering wheel and transmits an auxiliary force corresponding to the magnitude of the torque from a motor to a reduction gear provided on the steering shaft via an electromagnetic clutch. A detection means that detects the rotational speed of the reducer and outputs a voltage corresponding to the difference in these rotational speeds to the motor, and an electromagnetic clutch that takes in the output of the detection means and operates an electromagnetic clutch when the output voltage of the detection means becomes zero. 1. An electric power steering device comprising: a control circuit that outputs a control signal to the electromagnetic clutch to control the electromagnetic clutch.
