PURPOSE:To reduce the number of component parts, simplify an assembling work for the parts, provide a positive fixing of the parts and improve a stability of the fixed parts by a method wherein a damper rail is provided with a sealing mechanism for sealing around a supporting column and then the damper rail is fitted to the supporting column and a partition plate and fixed thereto. CONSTITUTION:Damper rails 22a and 22b are disposed in a communicating clearance 22 ranging from a right side end of a partition plate 21 up to a pair of forward and rearward C-shaped columns 23 and 24 so as to seal a spacing around the C-shaped columns 23 and 24 in a vertical direction. Since each of the damper rails 22a and 22b is set such that both longitudinal ends of each of the damper rails 22a and 22b are fixed to each of the C-shaped columns 23 and 24 and the partition plate 21, a positive fixing of each of the damper rails 22a and 22b is attained and at the same time its strength is further improved. Each of the C-shaped columns 23 and 24 are made such that a pair of C-shaped extreme ends 23a and 24a are fitted into each of corner cutout 31a of each of rectangular columns 31 so as to form a column. |
