Beschreibung
Zusammenfassung:	To provide a pipe member with a simple configuration which can reduce added vibration and improve durability.SOLUTION: A pipe member 10 mounted on an airframe 2 of a construction machine comprises an outer main pipe 12 and an inner auxiliary pipe 14 inserted into an inside of the outer main pipe 12. An outer diameter of the inner auxiliary pipe 14 is formed to be smaller than an inner diameter of the outer main pipe 12. The inner auxiliary pipe 14 includes a fastened portion fastened to the outer main pipe 12, and at least one end portion of the inner auxiliary pipe 14 is not fastened to the outer main pipe 12, to be a free end.SELECTED DRAWING: Figure 2 【課題】加えられた振動を低減することができ、耐久性の向上を図ることができる簡易な構成のパイプ部材を提供する。【解決手段】建設機械の機体２に装着されるパイプ部材１０は、外側メインパイプ１２と、外側メインパイプ１２の内部に挿入された内側補助パイプ１４とを備える。内側補助パイプ１４の外径は外側メインパイプ１２の内径よりも小さく形成されている。内側補助パイプ１４は外側メインパイプ１２に固着された固着部分を有すると共に、内側補助パイプ１４の少なくとも一方の端部は外側メインパイプ１２に固着されておらず自由端となっている。【選択図】図２
