ととなる。Function In the above-mentioned configuration, the main body wall and the side wall form a vacuum heat insulating material that insulates in a vacuum space, so that the heat insulating property is excellent. Even if the thickness of the main body wall and the side wall is made thin, efficient heat insulation is performed. Be done. Further, since the furnace body is formed by being divided into the main body wall and the side wall, the expansion difference between the inner wall and the outer wall generated when the temperature inside the furnace body is raised is absorbed. That is, the inner wall that expands in the circumferential direction presses the fine powder toward the outer wall, but the difference in expansion in the circumferential direction between the outer wall and the inner wall shrinks the gap between the outer wall and the inner wall, and expands the inner wall in the circumferential direction. Since the fine powder bodies are unacceptably tightly packed, the fine powders cannot flow and hinder the expansion of the inner wall. However, the inner wall is allowed to expand in the axial direction while being hindered from expanding in the circumferential direction by the fine powder body,
No thermal stress is generated on the inner wall, and damage to the main body wall is prevented.

It is arranged to fit inside. The main body wall 2 is formed in a double structure including an inner wall 2a and an outer wall 2b.
2b is formed of a thin plate material made of a metal material. A space between the inner wall 2a and the outer wall 2b is formed in a vacuum space and filled with the fine powder body 4. Further, the side wall 3 is formed by filling the inside of the hollow formed by the thin metal plate 5 with the fine powder body 4 and evacuating it. The main body wall 2 and the side wall 3 are not directly mechanically joined to each other, that is, the side wall 3 is fixed to the main body wall 2 via the structural member 6.

材７によって行なってもよい。The operation of the above configuration will be described below. First,
Since the main body wall 2 and the side wall 3 form a vacuum heat insulating material that is insulated by the vacuum space, the heat insulating property is excellent, and the vacuum space is filled with the fine powder body 4 and has sufficient strength. Becomes Therefore, the thickness of the main body wall 2 and the side wall 3 can be reduced to perform efficient heat insulation. When the inside of the furnace body 1 is heated, a difference in thermal expansion occurs between the inner wall 2a and the outer wall 2b of the main body wall 2. At this time, if the furnace body 1 is integrated into the main body wall 2 and the side wall 3 without being divided, the three-dimensionally expanding inner wall 2a is hindered from expanding by the fine powder body 4 to generate heat. Damaged by stress. However, in this embodiment, since the main body wall 2 and the side wall 3 are divided, and further, they are indirectly connected to each other via the structural member 6, the inner wall 2a hinders the expansion in the circumferential direction by the fine powder body 4. However, the expansion in the axial direction is allowed, and the deformation due to the expansion is only the shear deformation at the end portion of the main body wall 2, so that the expansion can be sufficiently absorbed. Similarly, the expansion of the metal plate 5 forming the side wall 3 is also absorbed. Therefore, according to the present embodiment, it is possible to prevent the damage by absorbing the expansion and deformation of the inner wall 2a when the temperature inside the furnace body 1 becomes high, and to prevent the risk of destroying the vacuum space. I can. Further, as shown in FIG. 4, the body wall 2 and the side wall 3 may be joined by bending the plate material 7 so as to have elasticity.

る。As described above, according to the present invention, the main body wall and the side wall are formed by the vacuum heat insulating material that insulates in the vacuum space, so that the main body wall and the side wall can be efficiently insulated even if they are thin. Can be done. Further, by forming the furnace body by dividing it into the main body wall and the side wall, it is possible to prevent the damage of the furnace body by absorbing the difference in expansion between the inner wall and the outer wall when the temperature is raised.
