A turning behavior control device of a vehicle comprising: a control yaw moment calculator for calculating a control yaw moment to be added to a vehicle; a first yaw motion adjuster, adjusting a drive force applied to the left wheel and the right wheel in at least one of the front wheels and the rear wheels of the vehicle to adjust difference in driving force between the left and right wheels; a second yaw motion adjuster adjusting a braking force applied to the left wheel and the right wheel in at least one of the front wheels and the rear wheels to adjust difference in braking force between the left and right wheels; and a yaw motion controller, outputting control signals to the first and second yaw motion adjuster to generate the control yaw moment, controlling the second yaw motion adjuster to increase braking force of the turning outer wheel while controlling the first yaw motion adjuster to increase driving force of the turning inner wheel in order to suppress the yawing motion of the vehicle, and controlling the second yaw motion adjustor to increase the braking force of the turning inner wheel, while controlling the first yaw motion adjustor to increase driving force of the turning outer wheel in order to facilitate the yawing motion of the vehicle, wherein: characterized by; when facilitating the yawing motion of the vehicle at a certain degree of understeering, the yaw motion controller increases an amount of control distributed to the first yaw motion adjuster, such that the increase in the amount of control is larger than an increase in the amount of control distributed to the first yaw motion adjuster in the case of suppressing the yawing motion of the vehicle at the same degree of oversteering; and when suppressing the yawing motion of the vehicle at a certain degree of oversteering, the yaw motion controller increases an amount of control distributed to the second yaw motion adjuster, such that the increase in the amount of control is larger than an increase in the amount of control distributed to the second yaw motion adjuster in the case of facilitating the yawing of the vehicle; at the same degree of understeering. a control yaw moment calculator for calculating a control yaw moment to be added to a vehicle; a first yaw motion adjuster, adjusting a drive force applied to the left wheel and the right wheel in at least one of the front wheels and the rear wheels of the vehicle to adjust difference in driving force between the left and right wheels;
