Abstract
PURPOSE: To enhance the strength of a cylinder tube as well as sink its manufacture cost by forming a cylinder tube in a solid molded construction through cold plastic processing.
CONSTITUTION: This cylinder tube 1 in a cylinder device is formed by cold plastic processing applied to a material tube of metal having a necessary wall thickness, to shape up it in different wall thicknesses according to the stress expected at respective tube portions, where the wall thickness of tube 1 on the bottom member 3 side is increased to obtain a thicker part 1b. The leg length for bevel angle at the part to be welded can be therefore chosen large for the time of inserting this thicker part 1b into the minor diameter part at the bottom member 3 and welding its end to this bottom member, so that the welding strength at this part can be raised up. At the head member 4 side, on the other hand, a thicker part 1a is formed, where the wall thickness is increased alike. The conventional requirement that a flange must be welded on cylinder tube 1 at the head member 4 side is eliminated thanks to this thicker part 1a, that assures simplified construction and reduced cost.
