A travel control device for vehicle (10) includes a steering transmission ratio variable device (14), a steering transmission ratio control device (16) configured to carry out such control that an actual relative rotational angle (θre) of the steering transmission ratio variable device reaches a target value (θret), a power steering device (18), a steering assist torque control device (20) configured to control the power steering device, and a driving support device (22) configured to correct a target steering assist torque so that an actual steering angle of steered wheels (19FL, 19FR) reaches a target steering angle for driving support. When the driving support device is in operation (Step 140), the magnitude of a change in a relative rotational angle generated by the control of the steering transmission ratio variable device is decreased (Step 150 to 200) compared to a case in which the driving support device is not in operation.
