A vehicle's drag-reducing apparatus, adapted to be arranged at the tail end of a vehicle, includes a diversion body positioned at the lateral surface of the vehicle and a rotary piece. The airflow flowing across the lateral surface of the vehicle body is guided to the tail end of the vehicle by the diversion body. One end of the rotary piece is pivoted to the vehicle body, while another end is fixed to the diversion body. Rotating the rotary piece will bring along the diversion body to be abutted against the tail end of the vehicle body or to be moved to the position far away the tail end of the vehicle body. Thereby, the open of the rear door at the tail end of the vehicle won't be hindered, even where there is an arrangement of the diversion body.
