Beschreibung
Zusammenfassung:	A jig of a heating apparatus is provided. The jig supports a ring-shaped workpiece when conveying and heating the workpiece. The jig includes a central structure unit, a rotary drive mechanism accommodated in the central structure unit, and a workpiece support connected to the central structure unit and configured such that the workpiece is placed on the workpiece support to surround the central structure unit. The workpiece support includes a plurality of rotating rollers arranged in a circumferential direction around the central structure unit. The central structure unit includes a conveyor connecting portion to suspend the workpiece support together with the workpiece placed on the workpiece support, and a driver connecting portion from which a driving force is input to the rotary drive mechanism. The rotary drive mechanism rotates the rotating rollers by the driving force to rotate the workpiece along a ring shape of the workpiece.
