Abstract: Disclosed is a paint drying furnace for baking and drying paint films on painted objects following a painting process. In the furnace of the invention, a shunt gas passage is provided for dividing a gas outputted from inner gas passages of a radiator means from a position of a radiator circulating gas passage upstream of a connecting point of a fresh air passage and mixing this divided gas into the gas circulating through the furnace interior circulating gas passage. With provision of this shunt gas passage, a combustion type radiator heating device acts also as furnace interior heating means.
