The upper limit position of this top nozzle can be set at the same height as the conventional one. Further, by moving the arm downward and further extending the top nozzle arm downward, the top nozzle is lowered to the lower limit position. The lower limit position of the top nozzle can be set lower than that of the conventional one. In this way, the top nozzle is moved up and down arbitrarily between the upper limit position and the lower limit position depending on the height of the top surface of the vehicle, and air is blown onto the top surface of the vehicle from the tip of the top nozzle to dry the top surface of the vehicle.
