The invention discloses a rear diffuser structure for a vehicular body. The rear diffuser structure comprises two tail wing structures, two lifting passages and a hydraulic pipeline. Each tail wing structure is positioned in the corresponding lifting passage and comprises a main wing, an auxiliary wing and a driving mechanism in parallel arrangment, wherein the main wing is positioned below the auxiliary wing, the front end of the auxiliary wing is close to the tail end of the main wing, end plates are arranged on the same sides of the main wing and the auxiliary wing, the main wing is fixedly connected with the end plates, the auxiliary wing is rotatably connected with the end plates, the driving mechanism comprises a main wing cylinder, an auxiliary wing cylinder and a base, and a rotary auxiliary cylinder is arranged on each base. The hydraulic pipeline comprises a hydraulic pump, a main wing pipeline, an auxiliary wing pipeline and rotary auxiliary pipelines, the main wing pipeline is used for connection and disconnection of the two main wing cylinders, each rotary auxiliary pipeline is used for connection and disconnection of the corresponding rotary auxiliary cylinder, and front sides of the end plates are provided with strip through holes above the auxiliary wings. The rear diffuser structure has the advantages that by adjustment of air resistance and down pressure of left and right sides of a vehicular tail portion, vehicular adhesion performance can be improved while tire load is relieved.
