ング装置。 A pair of sensors that individually detect the amount of torsion that occurs at two locations on the gearbox side and the steering wheel side of the steering main shaft and output electric signals respectively, and the rotation of the main shaft is controlled by energizing the driving electric circuit. A frictional force applying means that functions to apply a frictional force and a phase difference between them are determined based on the signal waveforms output from both of the sensors, and when this phase difference is a specified value or more, it is output from the sensor on the gearbox side. outputting an electric signal for turning on the drive electric circuit of the frictional force applying means when the phase of the signal waveform outputted is temporally ahead of the phase of the signal waveform outputted from the sensor on the steering wheel side; A vehicle steering device comprising a friction force control circuit.
