Abstract
A rear wheel steering motor generates rotational force. A movement converter has a converting portion coupled to the wheel steering motor and configured to convert the rotational force transmitted from the rear wheel steering motor into a linear movement. An MR fluid is applied on the converting portion. An inverter controls driving of the rear wheel steering motor. A magnet switch works in concert with the inverter to change a magnetic field to selectively provide the magnetic field to the MR fluid of the movement converter.
