PURPOSE: To perform drying of a car bumper having a concave part at its surface within a short period of time by a method wherein a speed of air blown in a first and a second moisture removing states is set to be faster than a speed of hot air blown during a first and a second drying stages.
CONSTITUTION: At a first drying stage, hot air 3a blown from a first hot air discharging port 3 is blown against a surface of a bumper 1. In this case, it is preferable that a speed of hot air 3a is set to be about 5m/sec. Then, air 4a blown from a second air blow nozzle 4 is blown against an end part 1b of the bumper at the second moisture removing stage and the moisture content left at the end part 1b of the bumper is removed with the blown air. In this case, it is preferable that a speed of air 4a is more than 20m/sec. With such an arrangement as above, it is possible to remove moisture content left at the end part lb within a short period of time.
