響、機械的衝撃を軽減することができる。 The furnace body 1 is held by a holding tube 2, one end of the holding tube 2 is fixed to a first support plate 31, and the other end is fixed to a holding plate 4. It is supported by a second support plate 32, and the first and second support plates 31, 32 are connected to the connecting member 61,
62, 63, and 64 are firmly fixed, so
Even if the holding tube 2 is heated and expands thermally, the part that is fixed to the first support plate 31 remains as it is, and the other end with the other presser plate 4 remains free with respect to the second support plate 32. It can thermally expand, absorb thermal expansion, and reduce the effects of thermal expansion and mechanical shock.
