In other words, since the horizontal mounting pieces of the air dam are attached to the horizontal wall of the bumper by overlapping them, a superior appearance with a sense of unity with the bumper can be obtained compared to the case where the air dam is attached directly to the car body wall. It is possible to precisely control the airflow that goes around to both sides of the vehicle body.
