To provide a coating drying oven wherein the temperature of a car body (a drying object) is uniformly raised and the inside of a drying oven is easily cleaned.
A returning section 8 is formed at the upper end of each of ceiling panels of a ceiling 7. Therefore, the flow direction of an air current flowing along each ceiling panel from the upper end of each ceiling panel toward the lower end is converted by each returning section 8 to form an air current which flows from about the center of the ceiling 7 through both the sides of the car body 1 toward the underside of the car body 1 in the drying oven. Thus, the temperature of the car body 1 is uniformly raised by circulating the air for drying to under the car body 1, while, in a conventional drying oven, the air (air current) for drying is hardly circulated to under the car body 1. Since the inside surface 7a of the ceiling 7 is coated with a fluororesin, a viscous contaminant or the like adhering to the inside surface 7a can be easily removed, enabling the drying oven 4 to be easily cleaned.
