摘要：PURPOSE:To facilitate handling of column such as replacement, etc., by constructing a dual spiral arrangement by providing the first and the second column propers wound in a spiral shape and the second column proper is placed on top of the first column proper. CONSTITUTION:A column is composed of the first and the second column propers 13, 14 filled with column filler inside respectively and wind in the spiral shape respectively. The first and the second column propers 13, 14 are connected on one side with a joint 15 one upon another. By this arrangement, a space occupied by the column can be reduced to a minimum and even if only an extremely limited space is available, a long column can be accommodated and handling of the column for replacement, etc. becomes easy and further, manufacturing costs can be reduced.
