Abstract: In a vehicle to which a vehicle body front structure is applied, an opening portion is formed behind a rear end portion of an arch portion. The opening portion is held in communication with an air flow passage, and is opened backward with respect to the vehicle. Then, the air caused to flow into the air flow passage during traveling of the vehicle flows from a front side toward a rear side with respect to the vehicle, and is discharged from the opening portion backward with respect to the vehicle.
