PURPOSE:To provide a cylinder having a polygonal section formed by extruding, the interior of which is axially partitioned into plural spaces of solid structure, which looks better externally and is conveniently handled. CONSTITUTION:A cylinder 1 is formed by extruding to be polygonal in section, and the interior of the cylinder is partitioned into three spaces A-C. In this arrangement, required apparatus are disposed in the spaces A-C, respectively, so that the cylinder can be conveniently handled because pipeline and wiring will not obstruct and it looks better externally.
