A diversion apparatus, adapted to be arranged at the tail end of a vehicle, includes a diversion assembly and a slide mechanism. The inside of the diversion assembly is hollow and formed an airflow channel. The slide mechanism is arranged fixedly at the tail end of the vehicle body and has slot tracks extended along the lengthwise direction of the tail end of the vehicle body. The diversion assembly arranged on the slot tracks can be moved and slid thereon. Therefore, the diversion assembly can be slid on the slot tracks and moved toward the front of the vehicle body to prevent the opening of the door leaf of the vehicle from being hindered by the diversion assembly.
