The tail spoiler includes a center portion which is arranged along the transition region and extends along the width of the tail trunk portion, and further an air deflection part connected to the center portion in a rearward and upward direction therefrom and an angular mounting part. The angular mounting part which is also connected to the center portion has at least two shank arms spaced from each other along the width of the motor vehicle. These two shank arms are located on the upper outer face in forward direction. In addition, the mounting part includes two further shank arms which are also spaced from each other along the width of the motor vehicle but are located on the rear outer face in a downward direction and are arranged at an angle less than 180° relative to the first mentioned shank arms.
