<P>PROBLEM TO BE SOLVED: To provide a vehicle behavior control capable of effectively improving straight running properties against disturbance even during straight running. Ž<P>SOLUTION: This rear wheel toe angle control device 11 comprising an electric power steering device 21 is installed on a variable rear wheel toe angle automobile V in which the toe angle θ<SB>RTC</SB>of a rear wheel 5 is variably controlled and used to control the toe angle θ<SB>RTC</SB>of the rear wheel 5. The rear wheel toe angle control device further comprises a yaw rate sensor 9 for detecting a yaw rate γ and a lateral acceleration sensor 10 for detecting a lateral acceleration αy. When the position of the device at which an external force Fp acts is forward of the center of gravity CG of a vehicle body, the toe angle θ<SB>RTC</SB>of the rear wheel 5 is set to a toe-in side according to the detected yaw rate γ and the lateral acceleration αy. When the position of the device at which the external force Fp acts is backward of the center of gravity CG of the vehicle body, the toe angle θ<SB>RTC</SB>of the rear wheel 5 is set to a toe-out side.
