開昭５６３９６５４号に開示されているような油圧シリ
ンダ、ピストンロッドが開発されている。Hydraulic and pneumatic cylinders, which are generally used as actuators for driving working machines such as construction machinery, are desired to have a strengthened structure and a reduced weight. For this reason, hydraulic cylinders and piston rods have been developed as disclosed in, for example, Japanese Utility Model Application No. 56-39603, Japanese Utility Model Application No. 56-39604, or Japanese Utility Model Application No. 5639654.

工が困難であり、又この結合部は材質の異なるものな結
合しているから強度が劣り、油漏れの原因にもなる。Even though the cylinder tube of the upper rudder hydraulic cylinder is made of carbon fiber, the cylinder head and cylinder bottom, which are made of metal, are connected at both ends, which increases the weight and requires a complicated structure at the joint. This requires processing, which is difficult, and since these joints are made of different materials, their strength is poor and may cause oil leaks.
同じくピストンロッドも両端の金属材料からなるロット
ヘッドとロットエンド部の重量が重くなり、結合作業が
困難であり、結合部の強度が低下する。Similarly, the weight of the rod head and rod end portion made of metal material at both ends of the piston rod becomes heavy, making the joining operation difficult and reducing the strength of the joint.
従って本発明の目的は加工が容易なシリンダ装置の加工
方法を提供し、併せてより重量が軽く一強度が強化され
