The present invention relates to an obturator of a heat treatment chamber, and, more particularly, to an obturator capable of enhancing sealing force and sealing maintenance within a chamber main body by applying filling pressure of nitrogen to a packing interposed in a contact boundary between the chamber main body and a door. In a common obturator formed by inserting, when inserting a packing at a portion where an external surface of an opening of a chamber main body meets a contact surface of a door, the packing in a groove formed at the external surface of the opening of the chamber main body, the obturator of the present invention is formed, after inserting the packing into the groove of the chamber main body completely, by forming a pressurization groove at a face opposite to a closing face of the packing, inserting an injection tube, which is introduced from the outside, at the groove of the chamber main body, and then positioning an end of the injection tube at the pressurization groove of the packing. |
