Abstract
In a diffuser apparatus, a plurality of diffusers are retracted in a lower part of a rear bumper and is deployed, and the operation of each of the diffusers is divided into a tilting operation and a sliding operation, so that airflow control is optimized for various situations such as driving conditions and driving environment, thereby improving driving stability and aerodynamic performance. In addition, the operation of the plurality of diffusers is controlled by a single driver, thereby simplifying the structure.
