A front-end spoiler arrangement formed on an under cover of a vehicle has to sufficiently reduce not only front lift acting on front wheels, but also air drag. The front-end spoiler arrangement comprises a front part, a ridge, a step, and a rear part. The step defines a space at the rear part. The front part and the step prevents an increase of the air drag, and air whirls s produced in the space generate downward force.
