操舵車の後輪操舵装置。 an actuator, a rear wheel steering mechanism driven by the actuator to steer the rear wheels according to a change in state from a neutral state, and a drive from the actuator by mechanically coupling the actuator and the rear wheel steering mechanism. Front and rear wheels including a connecting member that transmits force to the rear wheel steering mechanism, a battery device, and an actuator drive control circuit that is connected to the battery device and controls drive of the actuator using battery voltage supplied from the battery device. In the rear wheel steering device of a wheel-steering vehicle, a clutch device is provided in a part of the connecting member to selectively connect or disconnect the actuator and the rear wheel steering mechanism; a voltage drop detection circuit for detecting a voltage drop; and a voltage drop detection circuit connected to the voltage drop detection circuit to control and set the clutch device to a connected state when the voltage drop is not detected, and to switch the clutch device when the voltage drop is detected. 1. A rear wheel steering device for a front and rear wheel steered vehicle, comprising: a clutch control circuit that controls setting to a disengaged state; and an elastic member that biases the rear wheel steering mechanism to a neutral state.
