As a result, the upper portion of the interior space of the chamber unit 200 is closed by the upper shutter unit 310, and the lower shutter unit 320 is detached from the front surface of the frame unit 210. Accordingly, the heat treatment object may be loaded in the lower portion of the interior space of the chamber unit 200, or the heat treatment object disposed in the lower portion of the interior space of the chamber unit 200 may be unloaded.

In addition, after the heat treatment object is loaded or unloaded with respect to the lower portion of the inner space of the chamber unit 200, the lower shutter portion 320 is moved upward and downward by the upper and lower driving portions 330 disposed on both sides of the lower shutter portion 320.

For example, a groove G is formed along the longitudinal direction of the frame portion 210, and is formed to protrude on the groove G on one side and the other side of the groove G along the longitudinal direction of the groove G. The departure preventing jaw J may be welded. At this time, in order to prevent the thermal deformation of the frame portion 210 as much as possible when welding the departure preventing jaw J, the departure preventing jaw J may be spot welded.

In this way, as well as preventing leakage from the assembly portion of the shutter unit 300 by the sealing pad SP, the release preventing jaw J is welded to the sealing groove G, resulting in frequent opening or closing of the shutter unit 300. It is possible to effectively prevent the separation of the sealing pad SP, which may be caused.
