Abstract: PURPOSE:To remove a reaction tube and a cover without impact by forming at least one recess relatively on each of opposite faces of the tube and the cover for hermetically sealingly coupling the end of the tube to the cover. CONSTITUTION:A protrusion 11 is annularly formed along the inner periphery of a cap 8 at the center of the coupling face of the coupling section 10 of the cap 8, and recesses 12 are formed at both ends along the protrusion 11. Then, when the cap 8 is connected to the opening end of a reaction tube 2, the actually contact parts are only part of the coupling face of a coupling section 9 and the surface of the protrusion 11, and the contact area is resultantly reduced. However, treating gas is sealed by fitting the coupling section 9 of the oblique opening end to the coupling section 10 of the cap 8 parallel to the oblique end, and the interior is hermetically sealed. In order to set the interior of the tube 2 to a high temperature at the time of heat treating a wafer 3, the tube 2 and the cap 8 are thermally expanded, the adhering degree of the section 9 of the opening end of the tube 2 to the section 10 of the cap 8 is increased. Since the contact area of the sections 9 and 10 is only the surface of the protrusion 11, the cap 8 can be easily removed.
