PURPOSE: To facilitate a cleaning and exchange work for a work support part and to prevent damaging of a work during high temperature heat treatment. CONSTITUTION: The work support constitutes a part of a cassette 1 on which works W are loaded in multistage and is provided with a round shaft 2 and its support member 3, etc. The round shaft 2 is formed in a direction Y in one shaft in this example, and formed in a direction X on both sides. The support member 3 is mounted on four stays 13 at each of both sides, and the round shaft 2 is supported in four spots. Thus, during cleaning and exchange of the work support, the round shaft 2 is easily mounted on and demounted from the support member 3, and simple, rapid, and sufficient cleaning is practicable at the external part of a cassette. Exchange is also facilitated. Further, since the work is continuously supported in a long state, the support bearing of the work is low, and the work is prevented from being damaged even under high temperature treatment and vibration environment.
