PROBLEM TO BE SOLVED: To provide a vehicular toe angle control device capable of preventing any excessive control in a range of any mechanical play of an actuator. SOLUTION: The vehicular toe angle control device 6 has an electric actuator 8 for individually changing the toe angle of each wheel 3 of an automobile 100, and various kinds of sensors 10-17 for detecting the steering angle, the vehicle speed, the yaw rate or the like of the automobile 100, sets the target control amount of the electric actuator 8 based on the steering angle, the vehicle speed and the yaw rate, and performs the drive control of the electric actuator 8 based on the target control amount. The toe angle control device also has a correction coefficient setting part 53 for setting the correction coefficient so difference to reduce the target control amount when it is predicted that the load is applied to the electric actuator 8 by bringing the automobile 100 into contact with an obstacle on a road surface on which the automobile 100 travels, and a control gain setting unit 54 for reducing the control main so as to reduce the target control amount according to the correction coefficient.
