In the above air outlet device, the tip of the cylindrical lower end portion 21 of the air duct 20 is sandwiched between the inner peripheral surface of the grille flange portion 4 and the outer peripheral surface of the valve case 10 via the seal rubber 24. It is easy to position the lower end portion 21 of the air duct with respect to the grill 3, and the tip end of the lower end portion 21 of the air duct is surely supported by the grille flange portion 4 and the valve case 10. Even if it is small, it is possible to easily prevent unexpected deformation of the tip of the lower end portion 21 of the air duct, so that the sealing characteristics of the seal rubber 24 can be secured for a long period of time.

The lower inner surface 17 of the valve case 10
Is located at the same height as the bottom portion 22 of the air duct lower end portion 21 or below the bottom portion 22, so that water such as vehicle wash water from the outside may enter the air duct lower end portion 21. However, since the water is discharged outward from the bottom 22 of the lower end 21 of the air duct along the lower inner surface 17 of the valve case 10, it is easy to prevent water from accumulating on the bottom 22. Since the water in the recess 23 formed in the recess passes through the small groove 15 formed in the lower end surface of the valve case 10 and is gradually discharged to the outside of the vehicle body along the lower inner surface of the grill flange portion 4, the recess is formed. Water can be suppressed from being accumulated in 23 relatively easily.
