The invention discloses a device for adjusting air resistance at the tail of an automobile. The device comprises two tail wing structures, airflow channels and a hydraulic pipeline, wherein the tail wing structures are arranged at the tail ends of the airflow channels respectively. Each tail wing structure comprises a main wing, an auxiliary wing and a driving mechanism, wherein the main wing is arranged under the auxiliary wing; the front end of the auxiliary wing is close to the tail end of the main wing; the middle portion of the upper plate surface of the main wing is provided with a positioning plate which is fixed with respect to the main wing; and the upper end of the positioning plate is rotatably connected with the auxiliary wing. Each driving mechanism comprises a main wing cylinder, an auxiliary wing cylinder, a rotation assisting cylinder and a base, wherein an auxiliary wing cylinder body is rotatably connected with the positioning plate. The hydraulic pipeline comprises a hydraulic pump, a main wing pipeline for connecting and disconnecting the two main wing cylinders simultaneously, an auxiliary wing pipeline for connecting and disconnecting the two auxiliary wing cylinders simultaneously, and a rotation assisting pipeline for independently connecting and disconnecting each rotation assisting cylinder. The invention is to provide the automobile tail air resistance adjusting device capable of adjusting the air resistance and downward pressure at the left and right two sides of the tail portion of the automobile, thereby improving automobile adhesion performance and reducing tyre load.
