PROBLEM TO BE SOLVED: To provide a continuous heat treatment device capable of continuously performing heat treatment by properly conveying workpieces on which coating treatment is performed on both faces, by a walking conveying mechanism using a wire, while preventing contamination of a coated face and local unevenness of temperature.SOLUTION: A continuous baking furnace 10 includes a heating chamber 12, the walking conveying mechanism 40 and a plurality of jigs 50. The plurality of jigs 50 have the cylindrical shape having a hollow section 510 to which a first wire 16 and a second wire 18 can be inserted, in the longitudinal direction. These jigs 50 are respectively disposed on positions corresponding to a front end and a rear end of the workpiece 100, of the first wire 16 and the second wire 18 to support the workpiece 100 from underneath. The plurality of jigs 50 respectively have a taper section 506 tapered toward the workpiece 100 and kept into contact with the front end or the rear end of the workpiece. |
